Troubleshooting
Raceme catmint problems — and how to fix them
Raceme catmint (Nepeta racemosa) 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.
Crown rot in wet winters
The greatest risk is waterlogged soil in winter, particularly in heavy clay. Plant in raised beds or gritty, free-draining soil and avoid mulching over the crown. Good drainage is the single most important factor for longevity.
Cat damage
Cats roll on and chew plants, attracted by nepetalactone. Protect young transplants with bamboo stakes placed around the plant or wire mesh cloches until established. Older, established clumps generally recover well from cat attention.
Leggy or sprawling growth
In rich soil or partial shade, stems sprawl and flop. Shear plants by about half immediately after the first flush of flowers (usually late June–July) to promote a tight, compact second flush of growth and blooms.

Most raceme catmint issues are care-mismatch, not bad luck. Dial in the basics:
