Daylily (culture)

On this page you can find suggestions how to care and feed daylilies.The first is WATER, WATER, WATER. If you do nothing else to your daylilies, provide at least 1-1.5 inches of water per week. This is more important than any feeding program.


The second of things to do is take pH readings of the locations you grow daylilies. Regardless of how much nutrition is present not much is going to be available to your plants unless your pH is in the 6.2 – 6.8 range. You can find inexpensive pH meters in several stores.


The third suggestion is to incorporate as much as organic material as you can get your hands on into your garden beds. BORDER MUSIC Compost, composted leaves, animal manures, cottonseed meal, bone meal, end the like will help keep your soil loose, provide valuable trace minerals and retain moisture.



The Nitrogen (N), Phosphorus (P) and Pot-Ash (K) that we see listed on the front of our fertilizer bags deserves quite a bit of discussion. We must understand that our daylilies are not typical perennials. With most of our flowering plants a “balanced” diet is recommended lest we get too much leaf and little bloom. Thus 10-10-10 of 6-6-6 fertilizing programs are recommended. This is not the vase with daylilies. Daylilies are in the family of plant know as monocots. They’re in the same plant family as ornamental grasses or corn! Monocots prefer to feed at a rate of 3-1-2, or when in active growth 4-1-2. Thus, 18-6-12 should be an ideal mix for us. What tests always reveal is the fact that the middle number in our fertilizer (phosphorus) is not easily soluble, while most of our nitrogen is quickly leeched away. The bottom line is that if we do feed our plants year after year in the same beds we may end up with much too much phosphorus to the point where it is toxic.

Early in the growing season in addition to the basic fertilizer regimen it’s important to add the major minors: Iron (Fe), Magnesium (Mg) and Calcium (Ca). You can get liquid feeding of several kind when you look around. Those liquid feedings are also containing trace elements like Manganese (Mn), Boron (B) , Copper (Cu) en Zinc (Zn) that are essential for grow.

There’s a lot more to say about fertilizers, but this are the most important to know. Finally a last couple of thoughts: risk using too little fertilizer, not too much and hold in mind that organic sources are better than chemical fertilizers.
