Thai dwarf coconut
Coconut palms grow well in a variety of soils as long as it is well-draining. They do need an average temperature of 72 F. (22 C.) and an annual dwarf coconut rainfall of 30-50 inches (76-127 cm.). Fertilization of coconuts is often necessary for the home landscape. These palms are at risk of nitrogen deficiency, which is characterized by the coconut yellowing of the oldest leaves to the entire canopy. They are also susceptible to potassium deficiency, which begins to appear as necrotic spotting on the oldest dwarf coconut leaves increasing to affect leaflet tips and, in severe cases, the trunk is affected. Sulfur coated potassium sulfate is broadcast under the canopy at the rate of 1.5 lbs/100 square feet (0.68 kg./9.3 square meters) of canopy area four times per year to prevent the deficiency.
1. Coconuts require full sun to grow properly. Give them as much sun as possible.
2. Keep the soil continuously moist with warm water but do not soak the plant. In winter, should your plant survive, mist it frequently or provide high levels of ambient humidity with a humidifier.
3. Coconuts are not particular to their soil but do prefer a very well-drained, sandy soil. A standard palm mixture is a good idea.
