Why does your Savoy Cabbage Sonho F1 have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Savoy cabbage varieties like 'Sonho F1' have large, crinkled leaves that lose moisture rapidly through transpiration. If the soil is too dry, the turgor pressure drops causing wilting; conversely, waterlogged soil can cause root hypoxia, leading to secondary drooping.
Excessive moisture in cabbage beds promotes fungal pathogens that attack the root system of 'Sonho F1'. When roots decay, they can no longer transport water to the heavy foliage, resulting in permanent drooping even when soil is wet.
As a cool-season brassica, 'Sonho F1' is sensitive to high daytime temperatures. Extreme heat causes the plant to wilt temporarily during peak sun hours as a defense mechanism to reduce transpiration surface area.
A lack of essential macronutrients prevents the structural integrity of the cell walls in cabbage leaves. Nitrogen deficiency specifically causes older, outer leaves to yellow and lose their ability to stay upright.
