Troubleshooting
Snapdragon Achimenes problems — and how to fix them
Snapdragon Achimenes (Achimenes antirrhina) 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.
Leggy, non-branching growth
Pinch out growing tips when stems reach 5–8 cm in spring to encourage branching and a bushier, more floriferous plant.
Premature dormancy
Allowing the soil to dry out completely during the growing season triggers early dormancy. Water consistently and never let the root zone fully dry in summer.
Bud blast in cool temperatures
Flower buds turn brown and fail to open below about 17°C (63°F). Site the plant away from cold windows and draughts.
