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?
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.
