Daylilies require little maintenance - as long as they are healthy and bloom happily every year. It is not uncommon for gardeners to wonder why flowering suddenly slows down or even stops altogether. Fertilization might help…

Why should you fertilize daylilies?

The main reason for fertilizing daylilies is to encourage rich and intense flowering. These plants should be fertilized as soon as their abundance of flowers decreases or the flowers no longer appear.

It is also advisable to fertilize the daylilies to enjoy them for a long time. Many nutrients help the daylilies to defend themselves against diseases and pests, to be able to grow healthily and to sprout every year after winter.

When should you apply fertilizer?

When planting, you should enrich the soil with compost. So you do not need to fertilize the daylilies in the same year. From the 2nd year, an annual application of fertilizer is sufficient.

The exception is daylilies in tubs. They should be supplied with fertilizer more frequently. But beware: Daylilies should not be fertilized after July! The best period for fertilizing is from the end of April/beginning of May to June. If you fertilize later, you damage the plant. It can be difficult for them to adjust to winter if they add fertilizer too late.

Suitable fertilizers

The fertilizer should ideally have a nitrogen:phosphorus:potassium ratio of 5:10:5. The following fertilizers are well suited for fertilizing daylilies:

  • Long-term fertilizer (3- to 5-month long-term effect)
  • flowering fertilizer
  • compost
  • Damn
  • pond water
  • plant manure e.g. B. nettle manure, comfrey manure

Important notes on potential sources of error

  • sandy soils (poor in nutrients and humus) fertilize more than loamy soils
  • Never sprinkle fertilizer on the leaves of the daylily
  • Potted plants get liquid fertilizer
  • fertilize younger plants only lightly
  • Overfeeding leads to splitting of the flower stalks

tips and tricks

Alternatively, if you don't mind the expense of fertilizer, you can cover the daylily with a thick layer of bark mulch. This slowly and evenly releases nutrients to the plant and protects it from drying out.
