Care of Triangle Palm Trees
Triangle palms add that tropical feel to the landscape. The triangle palm grows its fan-like fronds from three points on the trunk, making a triangle. This palm is single-stemmed and will grow to 25 feet tall. Slow-growing with blue/green foliage, the triangle palm is hardy from USDA planting zones 9b through 11. The tree can be grown from seed and the seeds are poisonous if eaten.
Water the tree for long periods once a week when young and every other week for older trees. Spread the water in a 3- to 6-foot diameter of the trunk, as the root system spreads far. Cut watering back to once a month in early winter to prevent the tree from freeze damage.
Apply a palm tree food in April, June and August. Follow manufacturer’s directions on how much to apply for the size and age of the tree.
Cut off palm fronds that are yellowing or dead as close to the stem as possible, using a ladder and long-handled pruners. Do not prune the triangle palm as the fronds gather nutrition for the tree and cutting them off will leave the tree weak.
Apply an extra dose of fertilizer if the tree develops yellowing in the crown, yellowing or bleaching to the fronds or spots on the fronds that just do not look normal. These are signs of a nutritional deficiency, usually caused by using a general-purpose fertilizer not made especially for palms.
Care For Potted Palm Trees
Potted palm trees bring the feeling of the tropics indoors. In coastal areas, potted palm trees can tolerate full sun exposure. Palm trees need pruning to remove old leaves that have become damaged. As a general rule, palm trees need to be transplanted when the roots are coming out of the pot bottom, the soil becomes compacted or the palm tree becomes too unstable. Also the rim of the pot should be at least 2 to 3 inches above the soil line to leave room for watering. Potted palm trees like high humidity. One way to solve the humidity issue is to place a large tray filled with pebbles under the palm tree. Keep the tray filled halfway with water. Salt buildup causes leaf tip burn and eventual death of the palm tree. To prevent winter growth, do not fertilize during the fall or winter.
Do not try to climb the tree to remove dead fronds. You can get hurt or damage the tree. If it is too high for you to reach, call a professional.
