Care Guide
Pyrostegia vines are relatively easy to care for and can be grown in a variety of conditions. Here are some tips for caring for your Flame Vine:

Common Pests & Diseases
Pyrostegia is generally resistant to most pests and diseases. However, here are some potential issues to watch out for:
- Spider Mites: These pests can infest the plant and cause yellowing and browning of the leaves. Treat with insecticidal soap or neem oil.
- Aphids: These pests can cluster on the undersides of leaves and cause yellowing and curling of the leaves. Treat with insecticidal soap or neem oil.
- Root Rot: Overwatering or poorly draining soil can cause root rot in Pyrostegia. To prevent this, make sure the soil is well-draining and avoid overwatering.
