Daylillies

Question

For the past 2years my daylight has not flowered. It’s in a very large pot and we did split the crown into 2 last year but it still has not flowered why?

Answer 1

Are they planted too deep? Daylily plants should be set in the ground so that their crowns (the point at which the foliage and roots join) are about 1 inch under ground. Bulbs should be planted 6 to 8 inches deep.
Are they getting enough sun? Most varieties bloom best in full sun. More sun equals more blooms with daylilies.
Are you fertilizing them? Depending on your soil, a light fertilizer (and plenty of water) will help improve performance.
