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.

Slugs and snails

pest
Signs
Holes appear in the middle of the leaf rather than along the edge, young plants are eaten down to the ground, and there are slimy trails in the morning. On low-growing fruit there are gnawed pits.
Prevention
Remove the hiding places beside the bed: boards, stones, dense weeds. Water in the morning and not in the evening, so that the night is dry. Spread a band of coarse sand or gravel around the bed. Cover young plants with fleece. Pick them off at night, which is still the most effective measure.
