Wait about a month after planting or until plants begin to grow to start fertilizing. Fertilization in the first year should be frequent (every 2 months) with light applications of 0.25 lb (118 g) per plant. Use a 6-6-6, 8-3-9, 8-4-12 (palm special) with 2-3% magnesium or similar

Irrigation (watering)

Although pitayas are members of the cactus family and may withstand dry periods, they have a fairly high water requirement. However, excessive soil moisture will result in the development of bacterial and fungus diseases. A dry period is required for abundant bloom induction, but once plants flower, periods of drought may result in poor production. Therefore, no watering is recommended during the spring once summer rains begin or watering is initiated since flowering will be induced.
