Best Plant Food & Daylily Fertilizers

Daylilies are not heavy feeders and do pretty well without any plant food. But, if the soil assessment shows a deficiency, feed them with nitrogen-rich balanced fertilizers.

best daylily fertilizer

When the growing medium is fertile, daylilies do not need a lot of fertilizer. Hence, the light application of plant food also works for them. You can apply fertilizers before the flowers bloom or use a slow-release or continuous fertilizer when planting.


The best daylily fertilizer should have a decent mix of potassium, and phosphorous, with high nitrogen composition. Balanced NPK 1:1:1, meaning 20-20-20 or 10-10-10, can work well for all daylily varieties.


The only difference between these two variants is that the former has 2X nutrients in the same amount and will be costlier. However, it is safe to opt for slow-release and liquid fertilizers as they do not unnecessarily shock the plant.


Daylilies are easy to grow in backyards and pots. But when the soil is not adequately fertile, it impairs the blooming process and the overall growth. Thus, you need to use fertilizer. However, not every fertilizer is equally good.


Hence, the difference between the best plant food for daylilies and an average pick can be pretty drastic. This choice will also result in a difference between achieving dull, lifeless daylilies and beautiful, vibrant counterparts.


Sadly, picking the wrong plant food can be disastrous and usually impossible to recover from. So, to help you make the right pick, we present below a few of the best alternatives for daylilies.


Ideal NPK for Daylilies

As stated, daylilies love the balanced formula in NPK. Thus, you must always aim for nitrogen, phosphorous, and potassium in a 1-1-1 ratio, like 10-10-10 or 5-5-5.


However, if you are a serious planter and need a precise NPK ratio while shopping for daylily fertilizer,  you can follow our below-listed recommendations:


  1. 20-20-20 or 10-10-10 NPK is ideal during the fall. It can help the plant grow taller and stronger. In addition, it can also help the daylilies grow more flowers in number and size. A balanced NPK is also vital for maintaining healthy and vibrant blooms.
  2. 10-50-10 is a good NPK to achieve excellent daylily bloom all summer.
  3. 16-4-8 is ideal for good leaf and plant growth. You can opt for it in spring.


As much as the choice of a good fertilizer is vital, you must also ensure that you do not over-fertilize the plant. Ideally, fertilizing once a year with mulching is recommended for optimal growth. It is always safe to err on the moderation side than overfertilizing the daylilies.
