Tip
Alocasia with leaf spots has sunburn
In the partial shade, the alocasia impresses with its lush green foliage. However, if the exotic houseplant is confronted with a location in full sun, yellow-brown-black spots appear on the leaves due to the blazing sunlight. In contrast to yellow leaf discoloration due to waterlogging, nutrient deficiency or drought stress, the spots do not spread further. Fatally, this leaf damage is irreparable.
