Sea Rocket problems — and how to fix them
Sea Rocket (Cakile maritima) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot in heavy or wet soil
The taproot is especially vulnerable to fungal rot in poorly drained or overly moist compost. Ensure gritty, fast-draining growing medium and avoid overwatering.
