Roborowsky's Sage problems — and how to fix them
Roborowsky's Sage (Salvia roborowskii) 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.
Damping-off of seedlings
As an annual grown from seed, seedlings are susceptible to damping-off caused by Pythium or Botrytis in cool, damp, overcrowded conditions. Use a sterile, free-draining seed compost, water from below, and provide good ventilation to prevent seedling collapse.
Aphids on tender growing tips
Soft, sticky young shoots are attractive to aphid colonies, which distort new growth and reduce vigour. Check plants regularly and treat with insecticidal soap or a strong water jet at first sign of infestation.
