Planting A Palm Tree
Planting palm trees is similar, in most ways, to planting other kinds of trees. Nursery-grown palms are generally sold either potted or balled and bur lapped. Palms shipped UPS or parcel post are generally shipped bare root, to comply with state regulations concerning transporting soil, and to minimize shipping cost. Try to plant your tree shortly after purchase. If there is going to be any time lag between purchase and planting, make sure that the tree’s root ball is kept moist but not soaking.
When transporting and handling palm trees, use care. The bark is easily damaged and damaged areas leave the tree vulnerable to insects and fungus. The best time of year to plant is during the warmer months when the soil temperature is at least 65 degrees F.
Choose a location where the palm tree will receive full sun.
1. Dig a hole
The hole should be wide enough to fit the root ball with plenty of room to spare, twice as wide as the root ball might be a good rule of thumb in many cases. The hole should be just deep enough so that the tree is planted at the depth at which it was grown. Do not plant the tree any deeper as this may deprive the roots of nutrients and water.
2. Situate the palm tree in the hole, backfill with the freshly dug soil.
3. Build a soil barrier
When the palm tree has been planted, build a soil barrier around the circumference of the hole to form a dam that will hold water. Then lay down a layer of organic mulch around the tree. About three inches deep should do. You can also frame the base of the palm with landscaping stones or pavers.
4. Water Frequently
Frequent watering is crucial for newly-planted palm trees. Water your palm tree daily for the first two weeks and then tapering off over several months as the tree establishes itself. Use a bubbler or arrange a hose to slow soak the area around the tree. It is important not to allow the soil to dry out as this will severely weaken your new palm.
Maintaining a Palm Tree
Once planted, a palm tree is easily maintained with just a little effort and some tender loving care.
The most important factor in a palm tree’s health is soil. Compacted, nutrient-deficient soils found in most urban environments do not contain the components necessary for a palm to truly thrive. As steward to your trees, it is your responsibility to maintain healthy soil. You can do that in two ways.
Palm trees require a large variety of nutrients to survive and because they thrive in sandy, well-drained soils, these nutrients tend to leach away quickly. As a result, most common problems with palms are caused by a lack of nutrients or improper fertilization. There are palm-specific fertilizers available that release their nutrients very slowly to provide consistent, targeted feeding. If palm fertilizer is not available in your area, a balanced fertilizer containing 8-8-8 works well, or for more rapid growth, a 12-6-12 fertilizer. If your palm shows a light green or yellow color feed it a few spoons full of Epsom salt.
Other Care Concerns
The most important consideration is to ensure that your palm receives sufficient water for healthy growth. In desert areas and in the absence of regular rainfall, periodic watering is essential. Slow drip or bubble type watering over a number of hours is better than a simple drenching with a hose. As for how often, this will depend on the climate, season and rainfall frequency. In many areas, twice a month during the summer decreasing to once every six weeks during the colder season should be enough.
As they grow, the older fronds of palm trees will turn brown, die and, eventually, fall off. For esthetic reasons, you may wish to speed the process along a little by pruning off the dead fronds. Use some caution when pruning a palm tree. Prune only the dead fronds and remember not to cut too close to the trunk. In the case of a large tree, this is a job that should be left to a tree maintenance specialist.
Use caution when using lawnmowers and weed-whippers around palm trees as even minor bark damage may attract insects or invite disease.
