Pests and diseases

Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.

Fungus gnats

pest
Signs
Small dark gnats run over the surface of the compost or fly just above it. The larvae, with a shiny black head, live in the compost. At first the plant only loses its healthy look.
Prevention
The trouble is nearly always compost that is too wet and rich in peat: let the top layer dry out between waterings. A layer of sand or fine gravel on top of the pot takes the gnats' place for their eggs away.

Spider mites

pest
Signs
Small pale dots show over the upper side of the leaf, with a generally faded look. In a heavy attack the leaf browns or yellows and the plant dies. When it gets worse, a fine web is visible between the leaves.
Prevention
Most at risk are the plants that stand in the dry air of a room all year. Mist regularly and raise the air humidity to lessen the trouble. Keep new plants apart from the others for a few weeks.
