Fall-Scaping

10/3/2017

​​In Autumn, attention seems to be mostly focused on trees and foliage. When you take a step back to look at the larger landscape, it’s ALL the plants that contribute to Autumn’s magic. Shrubs, grasses, and other diminutive plants, should not be overlooked when planning a landscape that captivates in the fall.
Ornamental Grasses
Grasses are notorious for being big-impact, yet, easy-care plants. It’s not just in summertime that their beauty shows though. As fall progresses, some grasses will go through a color change. Some will turn from green to yellowish-tan, and varieties like our ‘Shenandoah’ Switchgrass and ‘Blaze’ Little Bluestem have rich purple and red hues in Autumn, before they turn tan. ‘Indian Steel’ Indian Grass, which has blue colored summer foliage, turns to copper, while the seed heads

​change to chestnut brown. When it comes to cutting grasses back we prefer waiting until late winter/early spring to do it, so that we can take full advantage of their texture and interest throughout fall and winter. Some years, heavy snow pack can cause your grasses to deflate, this isn’t a problem, but you can always wait for a ‘warm’ winter day and cut them down if they flop over too much for your liking.
Picture
​Seedheads 
We all know that deadheading is great for pushing out more blooms from perennials, but you may want to consider leaving summer’s last blooms on for the birds. Not only will our feathered friends appreciate having the seeds around for winter, but your landscape’s aesthetics can also be improved. The darkened, upright seedheads of ‘Powwow Wildberry’ Coneflower add texture, and the ‘Autumn Joy’ Sedum and ‘Arizona Sun’ Gaillardia are great candidates for providing interesting shapes.   
Evergreens  
Evergreens provide a backdrop for the changing scenery. My favorite part of fall is in the early to mid-stages when there is plenty of green remaining in the lawns and in some of trees that don’t turn until late in the season. The range of colors at that time is the greatest. Evergreens can prolong that lush look throughout the fall and winter. The bluish colors of the Colorado Spruce, Black Hills Spruce, and Douglas Fir are especially good to help the tan soft plumes of tall grasses like ‘Karl Foerster’ Feather Reed Grass stand out.

Unique Fall Features of Trees & Shrubs  
Choose Crabapples like our ‘Harvest Gold’, that have persistent fruit. Meaning, they hold on to their fruits well into the season. After leaves fall off, the small golden-yellow apples are revealed. All our Viburnums have gorgeous, bright fall leaf colors, and they also bear colorful small fruits. In particular the American Cranberrybush Viburnum has bright, glossy, cherry red fruits that hold on to branches well after leaves have fallen. Another tree with interesting features is the Grey Alder, which  has a seed structure that 

​To sum up; don’t miscount the small stuff. In every niche of the garden there lies an opportunity to display the beauty of fall!

Hot Stuff

7/15/2017

5 Comments

 
We polite Midwesterners like to talk about the weather. It’s an easy, neutral subject that’s usually banal small talk. I do it all the time, but often wonder if I’m being just plain whiney. This month, however, I feel like we have actually earned the right to gripe. June is not supposed to be as hot and dry as it was. My lawn is already going dormant, and my rain barrels were near empty. This June has been particularly brutal on new plantings! The atmospheric forces of strong wind, heat, sun and no rain have taken their toll.
Naturally, we have been receiving lots and lots of phone calls and emails about newly planted trees and shrubs turning brown. We get these types of questions every summer as soon as the weather really heats up. 
Picture
​This June 2017 we have seen a ton of these calls. Often, it’s the people who do spring plantings who have the hardest time figuring out what’s going on, they get used to a watering schedule when the weather is much cooler and the rain is more prevalent. However, the first week of hot, sunny weather and their trees stress because they haven’t accounted for the weather and increased watering enough.These calls also come from people who have planted in the previous year. Keep in mind that it takes a long time for a tree’s roots to grow enough to support it. Again, we find that people assume, because the tree looked great in the spring without supplemental watering, that it was good to go. On the contrary folks; keep a close eye on your trees for the first 3 years, and sometimes more. When it’s unseasonably hot and dry your tree will need some help.
 
If bad enough, drought stress can kill a new tree, but don’t panic at the first sight of brown leaves. Good news is, if caught in time your tree can recover. If you suspect drought stress e.g. sudden browning of leaves or some leaves are outright falling off, increase your watering and be patient. Your tree will look stressed for a while, but in time, they can re-leaf. (Sometimes, they won’t re-leaf right away, but might come back the next year, looking just fine.) 

So, get out there and check the moisture levels on your trees and increase the amount of water you are putting on them, and prepare for the heat!

How to Play in Clay

5/10/2017

1 Comment

 
“Does this tree like clay soil?”
A question we sometimes loathe. A more appropriate question is, “How well does this tolerate clay soil?” We have a lot of clay soil here in Iowa, and sometimes that clay is covered by a nice foot or more of lush topsoil. Ah, what privilege!  For others, (those of you in newer construction areas), all but a few inches of topsoil have been graded away through construction processes, meaning mucky, heavy clay is lurking one shovel scoop away. There are ways to work around clay.

​With vegetable gardens or flower beds, you can improve soil structure and texture by adding organic materials like compost, mulch, leaves…etc. Just keep adding these year-to-year, and in time, you will see an improvement.
Picture
On the flip side, when it comes to planting trees and shrubs, your best bet is to plant the right species for the soil that you have, instead of trying to change the soil. The vast majority of Bentley Ridge’s plants can take a fair amount of clay, but some are better than others. See the list of recommended plants that have the best tolerance at the end of the blog.

“Should I add some gravel, or sand when planting a tree to improve drainage?” NO. A tree’s roots spread very far and wide, so it is nearly impossible to amend the entire area where it will grow. Adding lighter materials, such as, peat moss, sand, or fancy ‘tree planting soil’ (sold at other retailers) to the planting hole, is not recommended either. The University of Minnesota has done extensive research on the topic, and have concluded that adding gravel to the soil will only make the problem worse because it creates a perched water table. Imagine digging a hole with hard clay and adding gravel at the bottom. It will pull more water out from the nearby soil, which will collect into the hole making it even wetter than before. Plus, over time, the clay particles will filter into the gaps in the rock allowing even more moisture to sit.
When considering light soil additives, your tree roots might be happy for a while in the light soil, but will not want to spread and break into the clay. Your best option is to dig a wide hole, score the sides of the hole with a shovel and backfill with the existing soil, taking care to break up/loosen the soil as you fill in the hole.
More tips for planting in clay:
  • Clay soil does not drain well and is often water-logged, so avoid overwatering. Before watering, dig down a few inches into the soil to gauge moisture levels.
  • Plant on the high side- It’s never good to plant trees and shrubs too deep, especially in clay soils. Raise the rootballs 1-3 inches above grade when planting in heavy soils. This is particularly true of evergreens, which don’t like soggy soils. If an evergreen has to go in a clay area be sure to plant them on the high side.
  • Clay soils are often alkaline (high pH). PH levels determine the availability of nutrients that a plant can absorb. Certain species can develop nutrient deficiencies, like iron chlorosis, which is often seen on Pin Oaks and River Birch, but can be present in many other species. Here is a link to learn more about chlorosis. There are many reasons why leaves turn yellow, so we suggest that if you suspect you have a problem, to have your soil tested first before treating your tree. Iowa State University performs soil tests.​

Do We Sell Christmas Trees...No...Maybe?

12/3/2016

0 Comments

 
With Christmas approaching we get asked the question, "Do you sell Christmas Trees?", quite a bit. The simple answer is no, we do not have trees that you can come in and cut down for a Christmas tree. However, last year we had an interesting request from a customer, she and her husband wanted to take a live tree home and keep it over Christmas and plant it in the spring. We were quite skeptical of this endeavor, but we saw it through and they purchased a 6' Austrian Pine. Recently they came back to the farm and gave us this update.
Picture
​​Christmas Tree Saver, chose a LIVE tree and plant it in the Spring.
 
My husband and I generally purchase a cut Christmas tree from a local tree farm, but grew tired of throwing away money at the end of the season, and the tree that had grown for several years. After researching and talking to local gardening guru’s, we decided to try a live tree and plant it the following spring.
 
We chose Bentley Ridge Tree Farm to purchase our “Christmas Tree” in 2015 for the first time. The farm had already closed for the season, by mid-November, but we were welcomed to come out for an appointment to pick something. Our Austrian Pine was a bit wild looking but that suited our needs. My husband is handy in all things, so he fabricated a 22-inch diameter steel container with hand hold slots, to keep our tree in its root bag before being planted a few months later. Other individuals could use a “Multi-Purpose Steel Utility Tub” found at home improvement stores.
 
After bringing our tree home mid-November, we placed our 6’ pine in our garage until after Thanksgiving. Getting it in our house was a bit interesting, but once in the front door we used a heavy drop cloth to slide it across the floor, instead of picking it up. The tree was decorated with lights and ornaments and watered well to keep it happy. I did need to purchase an extra-large tree skirt to fit the height of the container holding the tree. The tree skirt allowed gifts to be placed on the skirt at the base of the tree. Regular tree skirts fit but wouldn’t allow much fabric on the floor. We watered the tree about every other day, but checked it daily to make sure it wasn’t dry or oversaturated.
 
Once Christmas was over, and decorations put away, we moved the tree back to the garage until the end of February. When the weather was mid-30’s to 40’s most of the time we transitioned our tree to sit outside the garage. After the ground had thawed in April we planted the Pine and watered it well. The Austrian Pine has done well all Summer and Fall. We recently picked out our Christmas tree at Bentley Ridge for a second year. This time choosing a Colorado Blue Spruce. We will let you know how that one fares as well as an update to the 2015 Austrian Pine. 
So, the question of whether or not we sell Christmas trees might have a more complicated answer than we originally thought!

Have a Merry Christmas and Happy Holidays!

Autumn Agenda

9/8/2016

0 Comments

 
​​As many of you know, Autumn is a great time for planting. The temperatures have cooled which means your trees will benefit from reduced transplanting stress. Plus, you can get by with a little less watering. Here are a few things to know about caring for trees in the fall:
Protect:
We get asked all the time, which trees and shrubs do deer stay away from? The simple answer is, none! If hungry enough, they will browse just about anything, and they certainly don’t discriminate when it comes to antler-rubbing. So with that in mind, if you haven’t already done so, you need to get your trunk protectors on your trees! Young trees have very thin bark and can be easily and irreparably damaged by critters. Even if you think you don’t have deer in your neighborhood, other delinquents such as rabbits and voles can become desperate enough to gnaw off bark. Protecting your trees can be as simple as installing one of our trunk protectors. They are a rigid plastic mesh that doesn’t cost much and takes 10 seconds to install. Our trunk protectors can actually be left on year-round because they don’t actually touch the trunks. Other tree wraps and “protectors” should be removed in the spring because they and don’t allow the growing trunks to expand plus they can hold in moisture which can be damaging.
Picture
​For shrubs, or If you live on an acreage, wooded lot, or the edge of town where there are sure to be ravenous deer, you may just want to fence them completely. Expert tip: make the fence wider and taller than you think, deer are tall and can reach a long way, so 3’ tall chicken wire will not do the trick.
Fertilizing:
Yes, you can fertilize in the fall! The trick is to wait until the plants start to go dormant around mid-October before applying fertilizer, because you don’t want to flush out tender new shoots and leaves just before the cold hits.  Allow the plants to begin dormancy, then apply. The roots will still be actively taking in and storing nutrients even after the leaves have fallen off. The extra nutrients will be available in the following spring which gives your plants head start for the new growing season. If you have already purchased and have been using our Root & Grow fertilizer through early fall, no worries. The formulation is designed for root development, so it is low in nitrogen, and is safe to use this time of year.
Picture
​A Note on Perennials: Let foliage die back before cutting back. If you are planting late, you may need to add a layer of mulch in late fall or early winter to prevent frost heaving. Just remember to remove any coverings like mulch in early spring to avoid rotting.
 
…So grab yourself a PSL (pumpkin spice latte) to go, and come on out to the tree farm!

Introduction to Bentley Ridge Perennials

8/2/2016

0 Comments

 
It’s official, we are now selling perennials!
​     We hope that expanding our range of products makes Bentley Ridge Tree Farm & Nursery more of a one-stop-shopping experience. We are starting out with 18 varieties and we will see where they take us!
The varieties we grow have been hand-picked for these outstanding qualities:  
  • Winter Hardiness and Durability
  • Long Bloom Time
  • Low Maintenance
  • Range of Colors and Textures
  • Wow-Factor 
Picture
Still The Quality You Have Come to Expect!
​     As always, we grow everything we sell on site at our Urbandale Farm! Like all of our trees and shrubs, we grow our perennials in fiber root control bags, not plastic pots. Root formation is ideal in these bags - no circling roots, which means you don’t have to cut up or break up the rootball when you go to plant them. This also means that there is reduced transplanting stress. Our perennial bags are biodegradable and can technically be left on and planted in the ground. We do recommend removing at least part of the bag to accommodate the quickest root growth. (As a reminder, our tree and shrub root bags do need to be completely removed). Most people like to purchase and plant perennials in the spring, however, our stock is fresh, healthy, and beautiful!  They can brighten up any landscape immediately.

Try a Trio!  
         
     We have put together a few groupings that have complimentary colors and textures with long lasting impact, when planted together.
  • Shenandoah Switchgrass/Dark Towers Penstemon/Arizona Sun Gaillardia
  • Little Spire Russian Sage/Powwow Wildberry Coneflower/Karl Foerster Grass
  • Salvia Lyrical Blues/Indian Grass/Brightside Shasta Daisy
  • Swan Burgundy & White Columbine/Little Bluestem/Denver Daisy Black-Eyed-Susan

Managing Japanese Beetles: Balancing Control Effort with Accepting Loss

7/5/2016

0 Comments

 
The ubiquitous Japanese Beetle is here to stay. It is thought to have been introduced to the US in 1916 in New Jersey and has made its way to the Midwest. As a non-native, it doesn’t have many natural enemies, so it has been able to proliferate, and will continue to do so…at least until predators arrive. In commercial horticulture, we use a pest management method called Integrated Pest Management (IPM) which principles are to use a variety of techniques to control plant diseases. The point of IPM is to limit the use of pesticides; to not reach for the chemicals at first sight. The focus of Japanese Beetle control is not complete eradication, but minimization of their effects.

Life cycle
With IPM, it is critical to understand the life cycle of a pest to know how to treat the problem. Adult Japanese Beetles emerge from the ground in July, feed on leaves and flowers and mate, until late September when they lay eggs in the ground. The larvae of JBs live and feed on turfgrass roots in late summer-early fall and then move downward in the soil where they overwinter. In spring, the larvae move back up in the soil and feed on turfgrass roots again until July and then pupate and emerge as adults.

Control Methods

Topical Sprays
Foliar sprays are very effective at killing JBs. You can find a variety of ready to use sprays at your local garden center. Sevin, Spectracide Bug Stop, and Bayer Advanced Lawn & Garden Control sprays will do the job. Since they are broad spectrum they kill honeybees and other beneficial insects. They can also be harmful to birds, aquatic species and humans, so please limit your use.

Systemic Insecticide
This type of pesticide is applied as a root drench or injected into the trunks of trees. The pro of systemics is that the plant takes the chemical up internally, which means it won’t wash off when it rains, as with topical sprays. Larger plants take more time to move the chemical up to the top of the plant, so you may notice a delay in effectiveness in those plants. With systemics, the insect must ingest the plant before it is killed, so you will still see beetles browsing. Systemics do also harm honeybees and some other beneficial insects, so do limit your use.  

Organic Controls
There are some natural remedies and even though they may be less effective than harsh chemicals, they are definitely worth trying. As stated earlier, JBs don’t have major predators in the US but Milky Spore fungus and nematodes are biological agents that can be effective controls.They are used to kill grubs. Other products worth investigating are Neem and Cedar oil, which work to repel JBs.

Hand Picking
This is the most environmentally safe method, and can be done pretty easily on smaller shrubs and flowers. Pick off beetles and chuck them into a bucket of soapy water as you go. They will die in the soapy water, and you won’t have to go to the mess of smashing them between your fingers.

Plant species less commonly eaten by JBs
JBs browse hundreds of species but there are a few plants they love and some that we know they don’t go for as much. To have fewer JBs in your yard, avoid planting species they love the most.
  •   Plants that attract JBs:  Rose, Apple/Crabapple, Birch, Cherry, Plum, Norway Maple, Linden,             Walnut, Horse Chestnut, Aronia.
  •   Plants less commonly eaten:   Common Lilac, Red Maple, White and Red Oak,  Spruce, Fir, Pine,     Tuliptree, Holly, Hemlock, Arborvitae

 Three Common Myths:
Myth 1    If you treat your turfgrass with grub insecticide, you will have fewer adult JBs in your yard. Reality    JBs can fly up to 5 miles to find food, so the majority of beetles on your plants may not have come from your own turf. Don’t bother treating your turfgrass unless you know you have a grub problem. To scout for grubs pull up a few 12” x 12” squares of grass and count how many grubs you have. It’s recommended to not spray unless you have 7-15 grubs per square foot. Do this in April- May or September.

Myth 2   You should install a pheromone trap in your yard to lure and kill large amounts of JBs.
Reality   Pheromone traps use the scent of roses and a JB sex hormone to attract and trap adult beetles. What usually happens is that you will actually attract more JBs to your yard than what your plants attract on their own, without the traps. Many of these beetles never end up in the traps. Some still argue that traps may be effective on large areas of land like acreages, where you are able to place the traps a far distance from plants you are trying to protect.

Myth 3   JBs are introduced to your landscape from plants purchased at garden centers/nurseries.
Reality   JB adults lay eggs in turfgrass, so there are no eggs or larvae in other type of plants. It may be possible for a stray adult beetle to hitch a ride in a plant on the way home, but one beetle is negligible in comparison to the thousands that fly in from nearby turf.

Summary: It is important to know that you will probably never be able to get rid of every Japanese Beetle. One of IPM’s main principles is to accept a certain amount of loss. Yes, it’s annoying and unsightly, but it’s good to know that JB damage is almost always aesthetic and doesn’t kill affected plants.

ReThink your RePlanting

6/1/2016

0 Comments

 
Most trees can live a long time, so long that it almost seems like they will be around forever. Well, as we all know, “stuff” happens. Storms, diseases, and old age inevitably occur. Part of owning and caring for trees is dealing with loss. When a large tree falls, a tremendous void is made, literally and figuratively. It’s like an old friend is gone and now you’re left in the blinding sun. You’ve lost all your energy-saving shade, and now your neighbors have a full view of you in your pajamas. We’ve got some tips to help you make a good re-planting decision.
  1. You don’t have to plant a tree in the same place as the original. We know, it’s difficult to imagine a tree in any other place than where your original tree was, but after removing the tree and grinding out the stump, there will still be a large amount of roots which take a long time to decompose. This will make the planting of a new tree nearly impossible, and it is not ideal for the new tree’s roots. Consider a different place for the new tree, or plant it at least 6’ away from the old tree’s stump. If the original tree was young or small, you may be able to plant a nice new one in the same spot.
  2. You don’t have to choose a super-fast growing tree as replacement. One thing we hear all the time is, “We lost a tree, but we are getting up there in age and don’t have the time to wait for something to grow.” We hate to burst your bubble, but there isn’t going to be a magical tree that becomes full grown in a matter of a few years. Obviously faster growing trees grow faster, but asking if they will be fifty feet tall in a couple of years is unrealistic. Even though fast growing trees have their place, they may not be the best choice for all locations.
  3. You can view the loss as a new opportunity. The glass is always halfway full, right? The tree is gone, so now you can finally get that turfgrass established where it was once too shady. Who knows, that new sunny area could be all the inspiration you need to install a beautiful new sun-garden.
A lot of our customers at Bentley Ridge Tree Farm & Nursery have homes in suburban developments that were recently corn fields, so they aren’t dealing with the large tree loss scenario that was presented above. However, they do occasionally lose a newly planted tree. Tree loss in the first year after planting usually comes down to two things underwatering/overwatering or improper planting technique. Both of these things can be easily prevented if the proper research or questions are asked at the time of purchase. If your tree doesn’t make it the first time around you can accept the possibility that maybe you cared for it improperly, or you can do some research and come up with other potential reasons that the tree died (ex. bad soil, bad placement, bad weather, or ornery wildlife). When trees die, it is up to you to decide if you want to try again. You can try replanting the same type of tree in the same spot for the first replacement, but if you are struggling getting a tree established and it is the 3rd time around, it is definitely time to try a different species or different location in your yard. Either the tree you selected was not appropriate for the site, or you have an underlying issue with the soil. 
The good news behind all of this is that we are here to help, if you bring in pictures to us, or email us questions or concerns about your tree or shrub, we will do our best to make sure those issues get resolved, and that you end up with a happy tree!

Alternatives to Maples: A Lesson on Diversity

10/18/2015

0 Comments

 
Maples are usually the first thing people ask for when they step inside our gate, especially in autumn when the spotlight shines brightest on them. We see why they are so popular. Depending on the exact species, Maples can be fast growing, provide dense shade, display fabulous fall color and perform well in a variety of soils and landscapes. There’s one problem though, Maples are on the verge of being overplanted. What problems could arise from overplanting? Does Dutch Elm Disease or Emerald Ash Borer ring a bell? It’s not that overplanting causes diseases, but when aggressive diseases occur, they can target and wipe out a single species, or at least severely reduce populations. So by logic, it is wise to plant a wide variety of species to minimize loss.  While having a sugar maple, red maple and black maple sounds like diversity, they are all in the same genus. You will have much better insurance the further apart they are on the family tree.

There are instances where it makes sense design-wise to do mass plantings. Uniform rows of the same plant are beautiful. Going back to the history lesson, remember, Elm trees were commonly planted densely along streets to create that beloved covered archway feeling. After Dutch Elm disease swept through, those streets were left completely bare. Yes, it is good to have consistency and order, especially in shrubs and perennials, but when it comes to trees, mixing it up has benefits. You will end up with a more natural, park-like setting. Plus 'branching out' into multiple tree types, you get a wider range of features like spring blooms, form, fall color, bark color, evergreens, etc. You can really get the most out of your space.

What are other fall color options at Bentley Ridge?

Northern Red Oak
Canada Red Chokecherry
Pagoda Dogwood
Serviceberry

Shrubs: Nannyberry Viburnum, American Cranberrybush Viburnum, Blackhaw Viburnum, Arrowwood Viburnum, Burning Bush.

​Don’t get us wrong, we’re not telling you to not plant maples. We think they are good trees, but consider choosing alternatives. For those of you who don’t have any maples, the next time you look over at your neighbor’s yard in envy, embrace your uniqueness, you may just have a leg-up in the diversity department. The photos below are some of our best fall color selections- none are maples!

Common Plant Myths

9/17/2015

0 Comments

 
We get a lot of great questions from our customers. We like inquisitive shoppers. It tells us that they’re open to learning about plants and how to care for them, which makes them good ‘plant parents’. Occasionally we get questions that might make us chuckle, like, “Does a tree need to face the same direction in my yard that it’s currently facing at the farm where it’s grown?’ Short answer, no. Long answer, also no. We also get recurring questions; things that are old wives tales, things they heard from their neighbor next door.  Some even stem from miss-information they’ve received from professionals in the arboriculture, horticulture, and landscaping fields. Today’s blog post is to shed light on a couple common false assumptions about the manner in which trees grow and pruning myths.

To preface this topic, trees grow from the top up. Meaning, the branches that you see on a tree will always be located at that height on the trunk where they first originated. The branches don’t magically get higher and higher as the tree gets taller, instead, the tree will sprout new branches from the top (usually) as it grows. For some, this may seem like a no brainer, but you would be surprised how little some people pay attention to nature. These people get confused when they see our young trees at the farm. They say they want a tree that has branches that that start out higher up the trunk, you know, for ease of mowing.  Well how can that be? The tree is only 8 feet tall, so you wouldn’t have hardly any canopy left if you didn’t have those low branches. As the tree grows taller you can prune them out, silly! But don’t get antsy about limbing up your tree too quickly. We encourage waiting a few years before removing lower branches…the next paragraph will explain why.

 A false assumption about limbing-up is that if you cut off lower branches, it will stimulate the top of the tree to grow faster. We have also heard that removing branches will reduce competition for nutrients in other parts of the tree. (Insert game show wrong answer buzzer noise) There may be a shred of truth to this but the main point missing here is that branches have leaves, and leaves are where a plant gets its energy from. Remember biology class and photosynthesis? The more leaves you remove, the less potential for gathering energy. By removing too many branches, you can actually stunt growth. This is especially true of young trees. Put the loppers down and let the tree grow! The things you want to focus on early are crossing/rubbing branches or double leaders.

One of the most untrue sayings is, "Tree roots mirror the size and shape of a tree's canopy." This would incur that a tree's roots go as deep as the tree is tall. In actuality, most tree roots grow no deeper than 2 feet below the soil surface and can grow much much wider than the width of the canopy, Some tree species do have deeper tap roots, but the saying is mostly false 

We are not trying to belittle our customers here and say they are clueless, just that we are amused by some of things we hear. Hey, if we weren’t tree experts, we would assume the same things too!

Since there so many more myths to debunk, we will most likely re-visit this topic in future blog posts. If you have an old wives tale or a question about plants you’ve been trying to solve, shoot us an email at info@bentleyridgetreefarm.com or post it on our facebook page. We will try to answer them all.
