1、 Pruning residual flowers

After the lily withers, the remaining flowers should be cut off in time. Because the residual flowers will continue to waste nutrients, it is more beneficial to the growth of the plant to remove them in time. In addition to picking flowers, the withered and yellow branches and leaves should also be trimmed, but other leaves should be kept as far as possible, because they will continue photosynthesis and accumulate nutrients for the seed ball

2、 Less watering

Watering should be properly reduced after the lily withers. The reason is that the demand for water is not so large. Too much water will affect the development of seed balls. Then it is to control the growth of Lily and let it store nutrients into the seed ball as much as possible

3、 Moderate fertilization

After the lily withers, continue to apply fertilizer, and the amount of fertilizer remains the same as before. This is still to raise the ball. Generally, phosphorus and potassium fertilizer are the main fertilizer and less nitrogen fertilizer is applied, so as to avoid its continuous growth and continue energy for next year's flowering

4、 Pilling or not

All the branches on the lily wither. At this time, we should consider the problem of pilling. The so-called pilling is to take the seed ball out of the soil and preserve it. It is generally refrigerated, so that there is a process of vernalization. But generally, lilies don't need pilling, especially those with small balls
