Care of your tree
Fertilizing
Avoid fertilizing shade trees until late spring of the second year following planting. Fertilizers can “burn” roots or stimulate crown growth faster than the roots can supply water.
Staking 
Stakes and guy wires should be used only if support is necessary. When using, avoid common problems by following these guidelines: If the main stem droops, find the best place for support ties by moving your hand up the trunk to locate the point above which the top can stand on its own. Place the support ties about 6" above that point. Ties can be made many ways, but a loosely-fitted figure 8 tie made of polyethylene, cloth or webbed strap is easy to install, provides, good support and cushions the tree from rubbing against the stake. Using two ties will also minimize the chance of bark damage from rubbing. Regardless of the tie used, allow slack for sway. Avoid driving stakes through the root ball, or using stakes with flanges that will break roots when removed. Remove support ties after one or two years.
Mulch
Mulch is a young tree’s best friend. It holds down competing weeds or grass, retains soil moisture, prevents soil cracking that can damage new roots, protects the trunk from lawnmower damage and helps prevent soil compaction. Organic mulches such as wood chips or pine needles also contribute to better soil structure and aeration as they decompose. Avoid limestone rock and allow no mulch to touch the tree's trunk or be piled higher than 2 to 3 inches.
Summer Watering Tips
During a drought, it is extremely important to water young trees on a regular basis. A good rule of thumb is a minimum of 1 inch per week using the slow drip method. If watering normally, you should water your tree 7-10 gallons at least 2-3 times per week. This should be increased for larger trees. Always apply a 3'-4' circle of mulch on a newly planted tree. The mulch should cover the entire root zone to help retain moisture. Hardwood or cypress mulch generally lasts longer than pine mulch. Add mulch 2-3 times during the growing season, but keep mulch from piling around the trunk of your tree to prevent potential rot problems. By following these simple tips, your new trees should stay healthy and hearty during the harsh Houston summers.
Stress
Houston summers are famous for heat and humidity, and it appears that this summer will be no exception. However, to make matters worse, this spring was very dry. The heat and dry conditions are taking their toll on our trees. Some of our street trees are showing signs of stress. This is normal for newly planted trees in drought conditions. Trees that turn brown, especially bald cypress, often recover. This can occur several times before a tree becomes established in its new environment. Every street tree Trees For Houston plants receives care and maintenance for two years. Each week our contractors water and monitor almost 5,000 trees and seedlings lining Houston streets, freeways and schools. We will continue to plant and maintain Houston’s urban forest, to help make our city greener and cleaner for generations to come. |
