Why does your Brassica Pigeon F1 Round Victoria have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
In Brassicas like Victoria Round Cabbage, a lack of potassium prevents proper osmoregulation within the leaf cells, leading to necrosis at the margins and tips. This is common in heavy-feeding crops where soil nutrients have been depleted by previous plantings.
Excessive use of nitrogen-based fertilizers or high mineral content in irrigation water can cause salt buildup in the leaf margins. In cabbage, this osmotic stress draws moisture out of the leaf tips, resulting in dry, brown edges.
Brassicas have a high water content and require consistent moisture; rapid fluctuations between bone-dry and saturated soil cause cellular collapse at the leaf tips. This often occurs during the head-forming stage when transpiration rates are highest.
Strong, dry winds can increase the transpiration rate beyond the roots' ability to supply water to the outer leaf edges. This physical dehydration causes the thin margins of the Victoria Round Cabbage leaves to desiccate and turn brown.
