Equisetum hyemale problems — and how to fix them
Equisetum hyemale (Equisetum hyemale) 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.
Invasive spread
Rhizomes escape borders and colonise lawns and beds; the deep roots regenerate from fragments. Always confine to a sunken pot or solid root barrier.
Stems drying and browning
Almost always underwatering. The rootzone must stay saturated; brown, papery stems signal the bog has dried out.
Flopping or leggy growth
Too much shade or overly rich soil produces weak, leaning stems. Move to fuller sun and avoid fertiliser.
Winter dieback
In cold zones top growth browns off; this is normal. Cut spent stems to the base in late winter and fresh shoots emerge from the rhizome.
