Why does your Red Cabbage Ruby Perfection F1 have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlySpider mites are common pests in brassicas like Ruby Perfection, especially in hot, dry conditions. They pierce the leaf cells to suck out nutrients, leaving behind fine silk webbing and stippling on the cabbage leaves.
While often associated with flowers, thrips can attack young cabbage heads, causing silken scarring and fine webbing as they feed. This often results in silvery or necrotic patches on the developing red leaves.
In very dense plantings of Red Cabbage, excessive humidity can trap moisture between leaves, occasionally creating a fine, fungal-like webbed appearance if Botrytis or other molds begin to colonize.
