Three Trees to Plant this Earth & Arbor Day

This weekend we celebrate our magnificent home on Earth Day. A week later it’s all about the trees during America’s observed Arbor Day (April 29th). Abundant Tree Care would like to encourage you to take this opportunity to bring up more beauty with a variety of plants and trees.

If you’re in need of some ideas on which tree to plant, we’ve listed the details on three great options below. Contact our team with any questions.

(Great News: You can get a couple of the below trees, plus some others, for FREE at the Louisville Nature Center on Saturday, April 22, from 9am-1pm.)

White Dogwood   {Cornus Florida}

partial shade; moist, well-drained soil.

height:  20-30′    spread:  15-20′

Tough and stunning, the Dogwood is an excellent landscape choice in all four seasons. Flowers are showy in spring. Leaves turn red-purple in fall. Glossy red fruits attract winter songbirds.The inner bark of the flowering dogwood root contains the alkaloid cornin which Native Americans used as a treatment for malaria.

Eastern Redbud   {Cercis Canadenisis}

shade-full sun; high drought tolerance, few pests, low salt tolerance  

height:  20-30′    spread:  25-35′

Judas Iscariot was said to have hanged himself on a close relative after betraying Christ. The blooms of the tree, originally white, were said to have turned pink with shame or blood. Folk healers used the bark of eastern redbud to treat diarrhea and leukemia. The light magenta flowers are edible and look and taste great on fresh salads.

American Hornbeam  {Carpinus Caroliniana}

shade-full sun

height:  30′    spread:  25′

The wood on this tree is one of the hardest in our area. It is smooth and appears muscular.  Other common names for this tree are ironwood and blue beech. This tree is an excellent easement or median tree and tolerates the shade of other trees.

Arbor Day Around the World

It’s April and almost time for one of planet Earth’s favorite parties – Arbor Day

Arbor Day is a simple holiday in which we are encouraged to plant trees. In the U.S. it is celebrated nationally the last Friday in April, however, many states choose their own day to observe depending on the climate and most suitable planting season (Kentucky officially observes the day on the first Friday in April.).

The very first documented arbor plantation festival took place in the Spanish village of Mondonedo in 1594. The first American Arbor Day originated in Nebraska City, Nebraska on April 10th, 1872. The celebration is now observed across the world. Below are a few ways our neighbors honor the tree.

Without trees, where would this cute koala bear hang out?


The down under folks devote more than a few days to their beloved trees. Their Arbor Day is in June and then National Tree Day is the last weekend of July. Arbor Week is also celebrated at various times throughout the year according to the region.




In addition to Arbor Day, Canada celebrates Maple Leaf Day the last Wednesday in September during National Forest Week.




Arbor Day is celebrated in China on March 12th. This date was chosen to commemorate the passing of Dr. Sun yat-sen, known as the father of modern China.




In Israel, it’s Tu Bishvat or Tu B’Shevat (New Year of the Trees) and it’s celebrated on the 15th day of the Hebrew month of Shevat






In Namibia, a National Tree of the Year is chosen and planted. It usually takes place the second Friday in October



Fertilize Your Plants and Trees

Just like us, trees and plants require nutrients to live and grow. Also similar to us, the demand includes both macronutrients (like Nitrogen, Phosphorus, and Potassium) and micronutrients (Iron, Zinc, Copper). Different types of plants and trees established in different types of conditions need varying amounts of these nutrients, and deficiencies could result in a failure to thrive as well as stronger vulnerability to disease and vengeful insects.

Inside Louisville’s city lines, the threat can be even greater. Trees in urban and suburban environments are often under further stress due to conditions such as low moisture availability, competition with neighboring turf, and what is called the “urban heat island” effect.

But we do have some trusty tools in our belt to keep this risk in check. In addition to keeping newly planted trees watered and pruned, there are a variety of fertilizers available to nurture the soil your new tree or plant calls home. And these last months of winter, as we prepare for spring’s new growth, are a great time to act.

Finding the Right Fertilizer

Both organic and inorganic fertilizers can be used to supply these important nutrients. While inorganic fertilizers are highly soluble and more rapidly available to the plant, the effects are not as long lasting as organic fertilizers which take time to break down and release nutrients more slowly. A combination of both can be applied to tackle both immediate and extended needs, but Abundant generally prescribes organic, slow release fertilizers that we inject into the ground with a pump-driven soil probe.

The best indicator of the type of fertilization your plants and trees might need is a soil test. The samples are analyzed by a laboratory and a recommendation is made based upon the current level of each nutrient, the acidity or alkalinity of the soil, and the types of plants being grown. You can get a free soil evaluation by taking a sample to your local county extension office.

While the soil test is the most accurate indicator there are a few other ways you can measure what your plants lack and need:

Shoot Growth:If new shoot growth is in excess of 6 inches, fertilization is probably unnecessary. If growth is under 6 inches, fertilization might be applied.

Foliage Color:Yellow or off-color leaves could indicate a need for fertilization as these symptoms generally occur on trees which are not using up enough of one or more required nutrient.

Yard History: Trees and plants in yards that are fertilized for turf on a regular basis rarely need to have supplemental fertilizer applied. Resort to taking a look at your shoot growth to see if anything additional is required.
