Advance planting of white Easter lily bulbs will lessen a dreaded detergents, turpentine, coal tar and cat poison that can injure your plant. In the late Spring and early Summer each three-day period there will be a series of storms that take small amounts of white lily bulbs in southern California, and just as the white lily leaves start to cover the ground they will be blown away by strong winds. White lily bulbs can be buried vertically or horizontally in a pot of potting soil to be placed about six feet from the surface of the soil. The white lily bulb should be dug up to the bare trunk of the plant as soon as it is full leaf size. Eventually the root balls and the bulbs will begin to rot, and lilies should not be planted into any dry, stressed soil, because white lilies require plenty of water during their lifetime of 55 to 65 years of life.
To determine if you have clumps of white lilies in the ground you will need to look at the flower carcase on the top of the potting soil. If the flower is covered with a large stem of 4 inches or larger you have white lilies. When seed pods open or when the green flowers fade the white lilies are past a certain age. Long after the white blooms are gone the plants survive, although now resembling Bermuda grass. The once thin stems of the new plant are filled with tender green leaves that have just started to grow. From now until your new white lily plant grows and flowers, keep it well fed with a high quality organic fertilizer such as Sodium Thiosulfate, a mostly harmless and easy to apply soil amendment. Clear the seed pods from the bottom of the plant, and if the new leaves are dirty clean them up too. White lilies have dark green, creamy-white, blood-red or yellowing flowers that last from spring through fall, and start to fade when the plant reaches its fourth to fifth year of life.
