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.
Rodents and birds at the bulbs
pest- Signs
- Freshly planted bulbs are dug up and scattered over the bed or vanish without a trace. In spring nothing comes up in that spot. Birds rummage through freshly worked soil, rodents carry off the whole bulb.
- Prevention
- Bulbs are most vulnerable in the first few weeks after planting, until they take root. Lay a metal mesh over the bed or over the pot and take it off once the leaves come through. Level the planting spot and leave no husks or leftovers on the surface. Rodents leave daffodils alone, so plant them among the more popular bulbs.
- What to do
- A mesh over the planting spot is the only measure.
Gladiolus thrips
pest- Signs
- White blotches and streaks over the leaves and flowers. In a heavy attack the petals turn brown and the buds do not open at all. On stored corms and bulbs there are rough grey brown patches.
- Prevention
- The thrips overwinters on stored corms and bulbs, so at lifting cut off the top and remove it before they dry. It is most active from July to September. In a warm room it breeds all year, so keep the store cool.
- What to do
- The source suggests putting up with light damage, seeing to a clean lifting and encouraging the natural predators. It names no insecticide.
