About soil condition, Phoenix roebelenii grow best in fertile, well-drained soils, but are tolerant of a wide range of soil types and conditions. They will even grow in heavy clay soils, as long as the drainage is good. They are not particularly fussy about soil pH, but prefer a slightly acidic to neutral soil (6.0 to 7.0).
Like the other palm trees, the Phoenix roebelenii needs a lot of sun. It's best to plant this tree in an area that gets full sun all day long. If you can't provide that much sun, then you'll need to give the tree at least 6 hours of direct sun each day. If you don't, the tree will become weak and its leaves will start to turn yellow.
The temperature condition that is most ideal for the growth of the phoenix roebelenii is one that is warm and humid. This type of palm is native to Southeast Asia and is used to tropical climates. It can, however, adapt to other types of climates as long as the temperature does not drop below freezing. When growing this palm indoors, it is important to maintain a consistent temperature and humidity level to ensure proper growth.
Ideal humidity condition for this plant is around 50%. If the humidity dips below 30% the leaves will start to brown and the plant will become stressed. If the humidity is too high, the leaves will start to yellow.
Regarding fertilizer, this family of plant is not too needy, and too much fertilizer will actually damage the roots of a Robelenii palm. If the leaves of your plant are yellowing, this is a sign that you are feeding it too much. The ideal fertilizer for a Robelenii palm is a slow-release fertilizer that is high in potassium and low in phosphorus. An excess of phosphorus will encourage excessive growth of the plant, which is detrimental to its health. The roots of a Robelenii palm are very delicate, and too much fertilizer will burn them. If you see brown tips on the leaves of your plant, this is a sign that the roots are being damaged by too much fertilizer.
Pruning is an important part of caring for your phoenix roebelenii. Although this plant is relatively low-maintenance, regular pruning will help it stay healthy and looking its best. You can prune your phoenix roebelenii anytime from late spring to early summer. Simply remove any dead or damaged leaves or branches, as well as any suckers that may be growing from the base of the plant. When pruning, be sure to use sharp, clean shears to avoid damaging the plant.
Propagation is by division or by rooting stem cuttings. It is best to repot every 2-3 years. The roots are brittle and dislike disturbance. Use a well-drained potting mix. Water regularly during the growing season, allowing the top layer of soil to dry out slightly between watering. Fertilize monthly with a balanced fertilizer. These palms are relatively slow growing.
Usually, the plant growth rate in a 6 to 12 month period. they will reach a height of 3 to 5 feet and a spread of 4 to 6 feet. The record highest temperature that they can withstand is 122 degrees Fahrenheit.
Common problems for this kind of plant are leaf spot, root rot, and mealybugs. Leaf spot is a common problem for most plants and is caused by a fungus. The fungus will cause the leaves to turn yellow, brown, or black and can eventually kill the plant. Root rot is another common problem and is caused by a bacteria. This bacteria will kill the roots of the plant and can eventually kill the plant. Mealybugs are small insects that suck the sap out of the plant and can cause the plant to become stunted and produce less leaves.
