Daylilies thrive with the right nutrients, and selecting a suitable fertilizer is crucial for their growth and blooming potential. Here are key points to consider:

Types of Fertilizers

• Balanced Fertilizers: Look for options with equal parts nitrogen, phosphorus, and potassium, such as:
  • 10-10-10
  • 12-12-12

• High-Nitrogen Fertilizers: Daylilies particularly benefit from fertilizers higher in nitrogen, which promotes lush foliage and vibrant blooms. However, be careful with High-Nitrogen Fertilizers as too much will cause excessive foliage growth at the expense of bloom.

• Organic Options: This is probably the most important consideration for the average gardener. Compost and aged manure are the most effective way of improving soil structure and drainage, promoting beneficial microbial growth, and providing nutrients to the plants with less need for inorganic fertilizers.

Application Timing

To maximize the benefits of fertilization, follow this schedule:

Application Tips

• How to Apply: Add the fertilizer evenly around the base of the plant, avoiding direct contact with the crown and leaves to prevent burn. If you have adequately added compost to your garden beds, you should use half, or less, of the recommended amount of fertilizer. If you use aged manure, you do not need inorganic fertilizers at all.

• Watering: Water thoroughly after application to help nutrients reach the roots.

• How Often?: Fertilize once in early spring and again after the first bloom cycle. Avoid over-fertilizing, and too much Nitrogen, as this can lead to excessive foliage growth at the expense of blooms. Again, if you have added a good amount of compost to your garden beds, you can use less than half of the recommended amount of fertilizer or aged manure.

By following these guidelines, you can ensure your daylilies receive the nutrients they need for a stunning display throughout the growing season.
