Why does your Gerbera Royal Mini Deep Rose have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Gerberas are sensitive to high concentrations of salts from fertilizers or hard tap water. As the plant transpires, these minerals accumulate at the leaf margins, causing tip burn.
Gerberas require consistent moisture but hate 'wet feet.' Fluctuating between bone-dry soil and waterlogged conditions stresses the vascular system, leading to necrotic leaf tips.
As a cultivar often grown in controlled environments, 'Royal Mini' varieties can suffer from dry air. Low ambient humidity causes moisture to evaporate from the tips faster than the roots can replace it.
Excessive moisture on the foliage, especially in dense 'mini' varieties, can allow fungal pathogens to enter. While often presenting as spots, early stages can manifest as necrotic tissue at the edges.
