Gloxinias are naturally susceptible to several pests and diseases, such as Boron deficiency, Botrytis Blight, and Foliar Nematodes.
Boron deficiency is common among Gloxinias and affects their reproductive growth. You can treat and prevent boron deficiency by adding boron to your Gloxinias.
Botrytis Blight is a fungal disease caused by the Botrytis cinerea. This disease damages the buds, leaves, flowers, and bulbs of your Gloxinias.
Foliar Nematodes are microscopic worm-like organisms that infect and thrive on the leaves of your Gloxinias. This disease can cause dry and dull black spots on the leaves.
