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.
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.
After pruning the potted plants, you should take off the pot, cut off the withered and rotten roots, and then replace them with new nutritious soil. At this time, you can bury 50 to 100 pieces of fertilizer cake in the middle and lower part of the pot, which can meet the growth demand of the next year.
