Types of palm trees

With more than 2,500 palm tree species growing worldwide, they’ve adapted to a wide range of growing conditions. Palm trees are native to both arid and wet regions. Some grow in full sun, others in shade. Some stay small, while others grow more than 50 feet tall. Before selecting one for your yard or pool deck, be sure it’s going to be able to live there. The following is a small sampling of some of the popular palm trees that Americans like to grow.

Palm tree growing requirements

Palm trees grow best in conditions that resemble those of their native range. Consider your climate, soil, and moisture conditions, as well as available sunlight before making a selection.

Climate

Palm trees come from tropical or semi-tropical climates where freezing temperatures are extremely rare. Gardeners in warm regions, USDA hardiness zone 9 and higher, can choose from a diverse assortment of native and exotic palm trees for landscaping or outdoor containers. A few palm species can withstand winters as far north as zone 7. In cooler climates, select palms to grow indoors year round, or outdoors during warm weather only.

Light

Some palms require full sun exposure for at least six hours per day. Others grow best in dappled shade and suffer in excessive sunlight. A few tolerate a wide range of light conditions. Be sure to choose a palm tree that will grow in the conditions your landscape or home has to offer.

Soil

Many palm tree species grow just fine in either acidic or alkaline soils. They all require well-drained soil. Those planted in containers thrive in high quality, all-purpose potting soil. Avoid planting palms in low-lying areas where water pools after rain. Amend heavy clay soil with a liberal amount of soil conditioner before planting.

Moisture

Palm trees from arid regions, such as the Mexican blue palm, Pindo palm, and Triangle palm, need little supplemental irrigation. Some of these types can make excellent container plants.

Water-loving palms, like the Ruffled Fan palm, Everglades palm, or Sabal palm, may need to be watered daily. These could be good choices for wet locations and heavier soils.

How to plant a palm tree

Once you’ve selected a palm tree, it’s time to plant. Follow these guidelines to get your tree growing.

Timing

Plant palm trees in the late spring or early summer at the beginning of the main growing season. Doing so gives them the maximum amount of time to establish an extensive root system before winter dormancy, and helps to prevent cold damage.

Planting

Dig the planting hole two to three times the width of the tree’s root ball, and no deeper than the height of the root ball. If the soil is composed of heavy clay, make it three-fourths of the root ball’s height. Mix the soil from the hole with soil conditioner at a 1:1 ratio.

Carefully remove the tree from its container without damaging the heart. It may be easier to cut the container off the root ball. Gently loosen any tightly wrapped roots. Place the tree in the hole and confirm that it’s at the proper depth before backfilling with the soil mixture.

Build a low soil berm around the outside of the planting hole to help direct water toward the root zone. Finish off with a three inch layer of mulch.

Bracing

Tall, top-heavy palm trees may be susceptible to blowing over in strong winds. Smooth palm trunks don’t lend themselves to conventional tree staking, but you can support them with bracing.

  • About four feet from the ground, wrap the trunk with three layers of 16-inch wide burlap.
  • Use twine to attach four 12-inch slats of 2×4 lumber, vertically and evenly spaced, around the protected area of the trunk.
  • Drive four wooden anchor stakes two to three feet into the ground, aligned with the positions of the four vertical slats, four feet from the base of the tree.
  • Measure from anchor stakes to the vertical slats and cut four 2x4s to length for the braces.
  • Place the bottom of the brace against the inside of the stake and the top of the brace against the vertical slat. Nail the braces to the stakes. Secure the braces to the slats with wire and then (carefully) nail the brace to the upper slat without nailing into the tree.
  • Remove bracing after the first full year.

Palm tree care and maintenance

Once they’re in the ground, taking care of palm trees is pretty easy. With occasional feeding, watering, and pruning, they’ll thrive.

Water

Water daily for the first week or two after planting, then check the soil moisture three times per week. In rainy weather, supplemental watering is unnecessary. During hot, dry weather, daily watering may be required for palm trees in outdoor containers.

Fertilization

When palms aren’t properly nourished, they indicate their stress with discolored lower leaves. Prevent this with a good fertility program. Feed palm trees with 8-0-12, plus 4 percent magnesium palm fertilizer in early spring and early summer for consistently beautiful foliage. Don’t apply turfgrass fertilizer within 15 feet of palm trees, as the excess nitrogen will stress the tree.

Pruning

As palm trees grow, the lower fronds die back. To keep the tree looking its best and to eliminate hiding places for pests, prune the tree once or twice a year. Don’t remove foliage that hasn’t turned completely brown. Use pruning shears or a pruning saw to remove dead and damaged fronds, flowers, and fruit. On younger trees, leave at least two inches of the greenery on the trunk.

Cold weather protection

In the landscape, plant only palms that are hardy for your climate. In the event of an abnormal cold snap, protect these palm trees with an extra layer of mulch and cover the foliage with a frost blanket.

Outdoor container plants can be moved to a protected area, away from prevailing winds. A sheltered site along a south or southeast facing wall can provide some radiant heat as well as protection from wind. Potted palm trees can be wrapped with insulating material or placed on top of heating mats for added protection.

Fertilizing lawn

Besides mowing and watering, part of keeping a lush lawn is fertilizing it properly in the fall. If you've ever shopped for grass fertilizers, you may have heard of winterizing fertilizer. Basically, this type of lawn food, typically a nitrogen-heavy version, prepares grass with an energy reserve for winter. For an explanation of why you should fertilize your grass just before wintertime and how you should do it, read ahead.

Why would you fertilize your lawn during the winter?
Fertilizing way ahead of the growing season will help your grass grow healthy when the temperature warms up. You might see companies refer to such seasonal fertilizers as winterizing fertilizers. This name is somewhat misleading since you want to apply the fertilizer during late fall when grass growth slows down. They're all about preparing your grass for winter.

Daffodils
Daffodils are spring-blooming flowers, but they’re often planted in the fall. Daffodil bulbs should be planted two or three weeks before the ground freezes, so keep an eye on your local weather for the best results. In mild climates, daffodils can be planted as late as the end of November, while cooler climates may need to plant them in September or October.

There are still a few things that you can and should do outdoors in November to improve your garden.

Harvest the last of your fall garden
If you had a fall vegetable garden, be sure to bring in the last of the harvest. You may have already completed this step if you live in a cooler region, but, for those further south, this is the perfect time to wrap up your harvests. Be sure to store them somewhere dark and cool, like the fridge or a cellar (depending on what you were growing), or can them so they last longer. Any produce that’s left on the vine for too much longer will begin to rot or suffer frost damage.
