Troubleshooting
Red Riding Hood Mandevilla problems — and how to fix them
Red Riding Hood Mandevilla (Mandevilla sanderi 'Red Riding Hood') 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 from overwatering
The most frequent issue for container-grown specimens. 'Red Riding Hood' has a relatively small, compact root system that can quickly become waterlogged in heavy or slow-draining media. Ensure fast-draining mix, do not leave standing water in saucers, and reduce watering frequency significantly in autumn and winter.
Spider mites in hot, dry conditions
Spider mites are common on Mandevilla in warm, dry environments. Symptoms include fine webbing on leaf undersides and yellowish stippling. Increase humidity around the plant, spray foliage undersides with water, and treat with neem oil or insecticidal soap spray weekly until resolved.
Loss of flowers in low light
Moving 'Red Riding Hood' indoors or to a lower-light position in autumn frequently triggers flower and bud drop. If overwintering indoors, provide the brightest possible position and supplement with a grow light if needed. Even partial bud drop is normal during the transition to indoor conditions.
