Lilies should be cut off in time after they have withered. Because the residual flowers will continue to waste nutrients, it is more beneficial for the growth of plants to remove them in time. In addition to picking flowers, the withered and yellow branches and leaves should also be pruned, but other leaves should be kept as much as possible, because they will continue photosynthesis and accumulate nutrients for the seed ball.
Watering should be reduced properly after the lily has withered. The reason is that the water demand has not been so large, too much water will affect the development of the ball. Then it is to control the growth of lily, let it store nutrients in the seed ball as much as possible.
After the lily withers, it is necessary to continue to apply fertilizer with the same amount as before. Do so or to raise the ball, generally based on phosphorus and potassium fertilizer, less nitrogen, so as to avoid its continued growth, but also for the next year to continue to bloom energy
When all the branches on the lily are dead, the problem of pilling should be considered. The so-called pilling is to take the seed ball out of the soil for preservation, generally for cold storage, so that there is a vernalization process. But generally, lilies don't need pilling, especially for the varieties with small balls.
