The cherimoya performs well on a wide range of soil types from light to heavy, but seems to do best on a well-drained, medium soil of moderate fertility. The optimum pH ranges from 6.5 to 7.6. Cherimoyas need plenty of moisture while they are growing actively, but should not be watered when they are dormant. The trees are susceptible to root rot in soggy soils, especially in cool weather. Commence deep watering biweekly in April.
Drip irrigation is also an excellent way to supply water.
It is best to avoid poor water to prevent salt build-up. Drought-stressed trees will drop their leaves, exposing the fruit to sunburn. Cherimoyas should be fertilized on a regular basis. Increase the amount of fertilizer each year until the trees begin to bear fruit. Mature trees require an annual application of 4 ounces of actual nitrogen per inch of trunk diameter.
