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.
Vine weevil
pest- Signs
- The half round notches along the leaf edges in summer are the work of the adult beetles and do the plant little harm. The larvae are the danger: white grubs with a brown head eat the roots, the plant suddenly drops its leaves and dies, most often between autumn and spring.
- Prevention
- Most at risk are plants in pots and troughs. In a bed the damage is rarer. At repotting check the roots and the compost and pick the larvae out. You find the adult beetles in the evening with a light, when they crawl over the plants.
- What to do
- Pick the adults off in the evening, set sticky traps indoors and change the compost, removing the larvae as you go. There is no insecticide. As biological protection, water beneficial nematodes into the compost at the end of summer, while the larvae are still small.
