When topdressing it, it should be carried out according to the planting years and methods. If it is planted for the first time, the organic fertilizer should be applied when the seedlings are larger, and the dosage should not be too high. If it is one year or two years old, it is necessary to apply cake fertilizer with high concentration or continuous and effective organic fertilizer before winter. If it is planted on the ground, after pruning, dig a ditch around the rhizome and apply appropriate amount of cake fertilizer. If it's potted, apply a proper amount of cake fertilizer at the same time of root repair and soil replacement.

First planting

If the plant is planted for the first time, apply organic fertilizer or some media such as pine forest peat as fertilizer, or use cake fertilizer, bone meal and other organic fertilizer. Put 20-50g fertilizer in a 20cm basin when applying, and pay attention not to use too much.

Two, one or two years

One year or two years old plants should be applied with cake fertilizer of high concentration or organic fertilizer of continuous effectiveness before winter. For example, the rotten cake fertilizer can be used, to turn over the soil to apply, so that winter also has enough nutrients into winter, when dormancy is not applied.

If the plants are planted on the ground, after pruning, dig a circular ditch around the rhizome. According to the specific plant size, each of them can bury 200 to 300 grams of fertilizer cake, and can also apply about 500 grams of animal manure, so as to meet the nutrients needed in the next year.
