🌱 Fertilizer

Light applications of fertilizer once or twice a year during the growing season are enough for Cow horn. Do not fertilize in winter or summer when it is dormant. Cut back on fertilizer after repotting and wait a couple of months following repotting before applying any. Fertilizing helps maintain healthy growth and encourages blooms.
