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.
Aphids
pest- Signs
- Colonies of small aphids sit on the shoot tips and the underside of the leaves. The leaf curls and puckers, and sticky honeydew is left on everything below. The viruses they carry are more dangerous than the feeding itself.
- Prevention
- Go easy on nitrogen, because soft sappy growth is what aphids are looking for. Encourage the predators (ladybirds, lacewings, parasitic wasps). Use a reflective mulch, which puts them off settling, and a strong jet of water to knock the colony off the tips.
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.
