Troubleshooting
Snapdragon 'Rocket' problems — and how to fix them
Snapdragon 'Rocket' (Antirrhinum majus 'Rocket') 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.
Snapdragon rust
Brown pustules on leaf undersides, common in warm, humid weather. Space plants, water at the base, remove affected leaves, and choose rust-resistant strains.
Root and stem rot
Wet, poorly drained soil rots the base. Improve drainage and avoid overwatering.
Flopping spikes
Tall spikes bend in wind or rain. Pinch young plants for bushier growth and stake or net tall stands.
Aphids
Infest soft new growth and buds. Rinse off with water or treat early before they distort the spikes.
