Cabbage commonly gets clubroot (Plasmodiophora brassicae), which causes wilting and swollen, distorted roots even when plants are well watered. To address it, pull and destroy infected plants, avoid replanting brassicas in that spot for several years, and if you can, improve soil pH toward neutral (clubroot is worse in acidic soils). For prevention, keep soil from staying constantly wet and use clean transplants to reduce introduction.

Harvest when the heads feel firm and dense to the touch, typically around 75 days from transplanting. Look for mature outer leaves that are fully expanded and heads that have stopped “loosening” at the sides—if you can easily compress the head with light pressure, it likely needs more time. For best quality, harvest before prolonged hot weather and before heads start to split at the surface.
