Troubleshooting
Red Dragon Fruit problems — and how to fix them
Red Dragon Fruit (Selenicereus undatus) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot
The number-one killer. Caused by overwatering or poorly draining soil. Reduce watering and improve drainage immediately.
Stem rot
Soft, discoloured stem sections indicate fungal or bacterial rot. Cut back to healthy tissue and apply a fungicide paste to the wound.
Failure to flower
Insufficient light is the most common cause. Plants also require a slight dry period in winter to trigger flowering.
Mealybugs
White cottony clusters in stem joints. Treat with isopropyl alcohol on a cotton swab or neem oil spray.
Fruit cracking
Irregular watering during fruit development causes splitting. Maintain even irrigation once fruit has set.
