U.S. Department of Agriculture Hardiness Zone Map

According to the U.S. Department of Agriculture, “USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location.” This map is based on the average minimum temperature that occurs during the winter, per year, over the past 30 years. It is important to understand that these values are not derived from the lowest temperature that has ever occurred, but rather, the average annual radical minimum temperature during a past 30-year period.

You can visit the USDA plant hardiness webpage to learn your area’s specific plant hardiness zone by simply entering in your zip code. You can also view a 2012 USDA Hardiness Zone Map of Indiana on their interactive map page.

Hardiness zone adherence is not enough to sustain thriving, long-lasting, fully-performing trees and shrubs.

Root Damage

The most common culprits behind root damage are lawn mowers, construction work, pests, and unstable soil conditions. However, there are several more ways a root system can ensure stress and damage. In order to protect a tree’s root system, you must stay on top of all the proper tree care practices.

Here are some great tips to get you started on the right path:

Fortifying Roots

Annually, you want to revitalize your tree’s root system. You can do this by hand using a hand cultivator tool to gently loosen the top 2 to 3 inches of soil. This is a great way to alleviate soil compaction and let in more water and air to the roots.


Trees that are newly-planted, young, or under some sort of duress (i.e. illness, pest infestation, etc.) should be watered often. Keep in mind, however, that too much water is just as damaging as too little. Before each watering, use your fingers to test the moisture level of the top 2 inches of soil. If it is still moist to the touch, you can hold off one more day before watering your tree again. If it is dry, it needs more water.


Mulch is incredible important for tree care. Not only does it protect roots from sun damage, wildlife interference, and soil compaction, it also helps to retain moisture and add valuable organic matter to the soil. Keep your mulch at least 6 inches away from the trunk, but be sure to add 2 to 4 inches of depth.

Drip Lines

Take into consideration the tree’s drip line. This is where the edge of the canopy extends, and forms a circle around the tree. This area should be moist to the touch to ensure the roots are getting enough water.


When there is nothing more to do for your tree, be sure that you are implementing regular inspections to look for signs of trouble. Check for pest infestations, dry soil, damaged bark, missing foliage, discolorations, fungal growth, and anything else that indicates the tree is not as healthy as it should be.
