January to February is the ideal time to plant trees. During dormancy, all the energy in a tree is in the root system. They will establish very quickly. In the spring, they will be ready to grow leaves. Planting and establishing trees is all about managing air and moisture in the soil. The exception is palms. They are not technically trees and should only be planted in the late spring and summer. Three of the most common causes of poor plant establishment or tree death are planting too deep, under watering, and over watering. If appropriate trees are planted at the right depth and they are irrigated properly, the trees will thrive for years to come. As simple as this sounds, problems often arise that lead to poor establishment or plant failure.
Following ten critical steps can ensure proper tree planting:
1. Look up for wires and lights. Make sure that the tree species’ mature size will not interfere with any utility lines.
2. Find the topmost root and treat root defects. After removing the pot from the tree, remove all excess soil on the top of the root ball, until a root that is similar in diameter to the lower branches is located. That is the topmost root. Look for any roots that encircle the rootball, particularly close to the trunk. Remove any roots that will strangle the trunk. Cut all encircling roots at the point they turn to encourage root branching. Then, rough up or shave off all the roots on the perimeter of the rootball. If the tree is balled and burlapped, use a metal skewer to locate the depth of the topmost root.
Remove an inch or more for extremely rootbound trees.
3. Dig shallow and wide hole. Using the corrected rootball as a gauge, dig the hole slightly less shallow that the rootball. Loosen the top six inches of soil around the entire rootball.
4. Carefully place tree in hole. Lower the tree into the hole slowly.
5. Position top root 1-2 inches above landscape soil. Make sure that the rootball is above the surrounding soil grade. If balled and burlapped, the nylon straps, metal pins, burlap on top of the rootball, and wire basket above the grade will need to be removed.
6. Straighten tree. Check the tree from two directions at 90% angles from each other.
7. Add and firm backfill soil. Tamp soil with fingers, not feet. Do not stomp on the soil. It will compact the soil and reduce the oxygen to the roots.
8. Add mulch. Apply a 2–3-inch layer of natural mulch out to the perimeter of the trees branches, or beyond if possible. However, there should be 1 inch or less mulch on top of the rootball. Do not allow mulch to touch the trunk.
9. Stake and prune if needed. If there is a strong steady wind, staking is necessary. Otherwise, don’t stake. Make sure to do all structural pruning is done at planting time. Establish a central leader and remove crossing branches. But do not remove the lower branches. Just reduce the length. The tree needs to bring food to the lower portion of the trunk to increase the diameter.
10. Water the tree. Don’t walk away until the tree has been watered. Apply at least ½ gallon. The tree will need to be watered twice a week for 20-30 weeks. The larger the tree, the more water needed at each event. However, if the water doesn’t perk in within a few minutes, reduce the amount being applied. Overwatering can be as harmful as underwatering.
Many future problems can be avoided by paying attention to tree selection, planting and maintenance in Florida’s high wind climate. We may think of tropical storms causing tree damage but our typical summer thunderstorms can produce winds in excess of 50 miles per hour with downbursts reaching over 100 mph.
There is no way to protect trees from all storm damage. Trees are not adapted to worst-case storms, such as Hurricanes Michael or Ian, only to our average wind climate.
It’s wise to take time to select and correctly plant the right trees for North Florida.
Past hurricanes have taught us that large growing trees planted too close to curbs, sidewalks or buildings blow over easily because they don’t have adequate room to develop a sound root system. It’s best to either plant these trees farther away, plant trees that may stay small, or increase the size of space allocated for tree root growth.
Research and storms have taught us that tree roots need large soil spaces for strong, stable growth. The more rooting space trees have, the less likely they are to fail. Strong root growth is essential for tree stability and health. Large maturing trees need at least 30 feet by 30 feet (900 ft. sq.) of rooting space. Many construction practices such as paving over roots, raising and lowering soil grade, and soil compaction from equipment result in root injury for existing trees, making them less durable and less stable.

Studies have also shown that trees growing in groups better survive high winds compared to individual trees. A group was defined as five or more trees growing within ten feet of another tree, but not in a row.
A short list of large maturing, storm resistant trees to consider include live oak, sand live oak, bald cypress, pond cypress, black gum and magnolia.
Do some homework and take a look at tree species that have done well in your area. If you don’t want or need a large tree in your yard, there are many small and medium sized wind-resistant trees from which to choose, like Crape Myrtle and Vitex. Many palms are wind resistant too, particularly the cabbage palm.
Having success with trees in the landscape involves starting with healthy, well-developed trees. Plant the right tree in the right place. Follow good planting procedures, including not planting trees too deep and providing adequate root space to allow for strong, healthy root growth. Practice correct maintenance techniques, which includes learning how to prune to produce a structurally sound tree. Finally, consider if it is time to be proactive and have large over-mature, declining trees removed and replaced before the next storm.
There are some key practices that are necessary to make sure your trees and shrubs establish and thrive in your landscape. Learn a few pointers from UF IFAS Extension Escambia County to promote healthy establishment after correct plant installation. Learn about installing shrubs with the UF IFAS publication Establishing Shrubs in the Florida Landscape.
If you plan to purchase a container tree or shrub this cool season, it is important to follow a few important steps during installation. UF IFAS Extension Escambia County shows you how to find the root flare and remove excess soil above the root flare. These are a couple of steps that will help ensure your plant has a good chance at thriving in the landscape. #plantingdepth#treeinstallation
Pecan trees are well adapted to our area, making beautiful large shade trees. And, if the correct varieties are planted, they can provide pecans.
Only those pecan varieties that show some real resistance to disease problems are recommended for planting here in the humid south. Select grafted trees of Desirable, Curtis, Elliott, Moreland or Stuart varieties.

Obtain and plant your pecan trees during the winter – December through February. Purchase trees that are three to six feet tall. Larger trees are more difficult to transplant.
Give pecan trees plenty of room to grow. The distance between trees should be approximately sixty feet because mature trees are quite large. Commercial producers sometimes use a closer spacing, primarily because they are using varieties that will bear at an earlier age. But most of those varieties do not have good disease resistance and still require pesticide spray at times. Homeowners will not have the needed equipment to spray a large pecan tree and the drift from such sprays would not be desirable around your home, so commercial varieties aren’t recommended for home plantings.
One of the keys to survival of a pecan tree is not allowing the root system to dry out before, during or after transplanting. Regular watering will be required for a period of at least six months or until the young tree is well established. The planting hole should be 18 to 24 inches wide and only as deep as the root system. Spread the roots so they are not matted together. The planting depth is critical. Place at such a depth that the uppermost root is at or near the soil surface. Excessively deep planting can result in eventual death of the tree.
When planting your tree, there is no need or advantage to using peat moss, compost, manure or other organic matter in the planting hole. Plant the tree in the native soil without amendments.
Do not fertilize when the tree is planted. Wait until May of the first year after planning to apply fertilizer.
Remember that pecan trees are large at maturity, with branches spreading 30 feet or so from the trunk. Also, because of the brittle limbs and failing nuts, it’s best not to plant these trees too near the home, driveway or sidewalk.
