How often to water Dragon fruit
- Spring–Summer (Mar–Sep)
- Every 7 days
- A cactus, but it drinks during growth: water thoroughly once the soil is dry all the way through, about every five to ten days.
- Autumn (Oct–Nov)
- Every 10 days
- Taper off as it cools, to about once every ten days once the soil is dry.
- Winter (Dec–Feb)
- Every 30 days
- Nearly dry: as a guide, moisten lightly about once a month on a mild day, since cold, wet soil rots the stems.
Light and placement for Dragon fruit
As a guide, a sunny spot outdoors from spring to fall, since it needs strong light to flower; moved into full sun too suddenly it generally scorches yellow, so acclimate it gradually in spring.
Overwintering Dragon fruit
Overwintering guide: 5°C (41°F) or above
Tropical and tender, so keep it above 5°C as a guide: move it to a bright indoor window when nights fall below about 10°C and let it rest nearly dry, since frost generally turns the stems to mush.
Fertilizing and repotting Dragon fruit
Fertilizer
As a guide, slow-release fertilizer about every two months or a diluted liquid feed about monthly from April to October, and none in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Dragon fruit
