Never buy or plant a soft daffodil bulb, as that means there is rot or another disease inside the bulb. Bulbs with two tips will produce two stems. Small bulbs may not flower in their first year. [4] X Research source
Only plant one type of daffodil per hole or trench.
In places with severe winters, ensure at least 3 inches (7. 6 cm) of soil covers the bulbs![8] X Research source If you can’t tell which end is “up,” plant the bulb on its side.
Do not place daffodils in the same vase as other flowers. Daffodil sap causes other flowers to wilt. [11] X Research source
To be safe, don’t start pruning until late May or June. [12] X Research source
Yellow spots on the stems or leaves may indicate Stem Nematodes. Destroy all the infected plants, and then do a hot water treatment. Treat fungal diseases such as rot and mildew with a fungicide spray, and treat viral diseases, such as the yellow stripe virus, with an insecticide spray or the hot water treatment.
