In short
The last frost is not on the same day everywhere, so the recorded weeks are a guide and not a date.
Growing conditions
The leaves are listed as edible and as toxic at once. The toxicity is to cats and dogs, not to people.
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.
