Plant lilies with at least 5″ of soil above the bulb which means a LARGE pot if you are using one. Soak the lily bulbs over night in cold water before planting them if they look a little soft. Lilies can be planted from late autumn to early spring.

How do you keep calla lilies blooming?

Too much nitrogen will encourage foliage to grow but will prevent the plant from blooming. Switch your fertilizer to one that is higher in phosphorus than nitrogen to make calla lilies bloom. If your calla lilies are not planted in an area that gets plenty of water, this may be causing them not to bloom.

How do you keep calla lilies from falling over?

Water the callas once or twice weekly, before the top 1 inch of soil dries completely. Provide 1 to 2 inches of water at each irrigation so the soil remains moist to a 6-inch depth. Lack of moisture causes the stems to wilt and weaken so they cannot support the weight of the flower bud or flower.

Calla Lilies are not drought resistant and should never be allowed to totally dry out. Soggy soil is not good either and they should never sit for more than 15 minutes in a saucer of water.

What month do you plant lily bulbs?

Plant lily bulbs in the fall, a few weeks before the winter brings freezing temperatures. Bulbs planted in the autumn will have well established roots in the spring. The bulbs benefit from a winter chill to produce big blooms. We do advise planting in spring in areas with particularly harsh winters.
