The Emerald Ash Borer was recently discovered in Boulder, CO. This devastating insect had destroyed millions of ash trees in other

states. To see the latest recommendations about Emerald Ash Borer, please visit the official multinational website created by universities from many states and Canada, EmeraldAshBorer.info or the new Colorado-based site, EABColorado.com


Here is information about Emerald Ash Borer from experts at Colorado State University

if you suspect Emerald Ash Borer, please have the insect positively identified by before beginning any course of pest control. Contact your local CSU Extension office for information and identification. Click here for a list of offices.

In late September of 2012, Tagawa Gardens was approached to help the national website Ask.com answer some frequently asked tree and shrub questions.  Mike Landers, one of our Certified Arborists who also owns Mike Landers Tree Planting Service (the company which we recommend for tree planting) came to the plate to assist us, and is featured in the following videos produced by Ask.com (links used with permission):

Whether you are looking to add a few new plants to your yard or are in need of ideas and plants for a whole new landscape, we invite you to take a stroll through out beautiful, well-stocked outdoor Nursery. We offer  you a wide range of plant choices that will provide a variety of options for colors, shape and size. from evergreen to deciduous trees and shrubs to hardy groundcovers, fruiting trees, shrubs and vies, the Nursery is THE place to come for your tree and shrub needs. All of our plants have been selected to perform well in our sometimes-challenging Colorado climate.

Here in the tree and shrub nursery, we encourage you to think of trees and woody shrubs as the structural components of your landscape – the ‘bones’ of any great landscape design.  Once the structural elements are in place, it is much easier to fill in with perennials, ornamental grasses and annuals for bursts of seasonal color and interest.


Let Our Experienced Staff Assist You!

Our tree and shrub nursery staff is a team of knowledgeable, talented horticultural professionals and Arborists, each with their own area of expertise.  We are particularly familiar with plant choices and cultural practices suited to Colorado’s climate.  Come in and let one of us help you with plant selection, design challenges, plant identification and plant problem diagnostics.  Our goal is for all of our Nursery guests to have a successful, enjoyable and educational visit.

Frequently Asked Questions about Trees and Shrubs

1. How do I plant a tree or shrub?

Dig the planting hole AT LEAST twice as wide as the root ball (3 to 5 times as wide is better) and 2” to 4” shallower than the depth of the root ball.  You want the root flare (the area where the main roots come out from the trunk of the tree) to be 2” to 4” ABOVE grade.  Too high is always better than too deep!  The soil removed from the hole can be amended by 25% or less (never more) with organic compost.

Place the tree or shrub in the hole and remove any material around the root ball such as wire baskets, burlap and twine.  Add the amended soil halfway up the side of the root ball and then water.  Add the remaining soil and water again, making sure that you do not cover the top of the root ball with soil.  Add a 2” to 3” layer of bark mulch, being careful not to allow the mulch to touch the trunk.  Mulch up against the trunk or main stem can lead to crown rot.

2.  How often should I water a tree?

This is a tricky one. The frequency and the amount of water may vary greatly depending upon such factors as soil type and drainage, weather conditions, time of year and plant species. A good rule of thumb is to water the plant, then dig down about 6" outside of the root ball - not into the root ball- take a handful of soil and squeeze it into a ball in your hand. Now open your hand. If the soil stays together in a ball, the soil is wet enough. If the soil crumbles and does not form a ball, continue to water.

The biggest problem we see in the landscape is root rot from over-watering. Remember that a plant needs oxygen as much as it needs water and the only way that a plant gets oxygen is through its root system. Over-watering is caused by the frequency of watering, not the amount of water applied. So let your soil dry out somewhat in between watering.

3. When is the best time to plant a tree or shrub?

The very best time to plant a tree or shrub is in the early spring while the plant is still dormant and before it leafs out. However, here in Colorado, successful planting – especially of container-grown plants - may be accomplished throughout the year.  If you can get your shovel into the ground, you can plant!

4. How do I take care of my tree or shrub during the winter?

Trees and shrubs are designed to enter winter dormancy with little “help” from humans.  But in Colorado, there are a few things that we can do for our trees and shrubs to get them through the harsh winter conditions in the best of health. The top three things we can do are these:

     1) Winter Watering

     

We cannot overemphasize the importance of watering trees and shrubs during the winter!  From roughly October through to March (or, during the time landscape irrigation systems are turned off) plants need to be watered once a month, at a minimum.  If the temperatures reach the 40s or higher during the day, you can water.  Be sure to water in the morning so that if the temperature does drop below freezing overnight, the water will not pool and freeze around the crown of the plant.

    2) Mulch

Apply a 2” - 3” layer of mulch (bark chips, chopped leaves, pine straw, etc.) in the fall. The extreme temperature fluctuations of our winters can be very hard on the root systems of your tree or shrub. By adding a layer of mulch you will help keep the soil at a more even temperature, preventing root death.

     3) Wrap

Use a crepe-type commercial tree wrap on newly planted trees to help prevent sun scald. Start at the base of the trunk and work upwards to the first branch. Wrap your tree at Thanksgiving and be sure to remove the wrap by Easter. If there has been any damage to the tree’s bark, do not apply wrap as it could provide a haven for insects or diseases as they move into the trunk.

5. What's wrong with my tree?/What kind of plant is this?

Tagawa’s Nursery staff is more than happy to try and help you determine what might be happening to your tree or shrub or make an identification for you.  You are welcome to bring in samples, but we ask that you use guidelines before you do:

     1) Zip-top baggies are everyone's friends!

When bringing in tree or shrub samples – especially in a suspected disease or insect situation – please put the material in a sealed plastic bag before you bring it in to the Nursery.  We appreciate your help in keeping our Nursery plants safe from any introduced infestation.

     2) If one leaf is good, many leaves are better!

We’re good, but we’re not always that good.  If you want to know what a particular plant is, bringing in a 6” – 8” (or larger) section of branch so that we can look at multiple identifying characteristics will help us make the quickest and most accurate plant identification for you.  When in doubt, more is better.

     3) We'd love to come visit, but we just can't...

Some things have to be seen in person for an accurate diagnosis to be made.  While we will do our best for you over the phone or via e-mail, please understand that in some cases, the best way for us to serve you is to recommend the services of another reputable horticultural professional.
