Timing of fertilization for orchids

① early spring potted orchids go out of the house, but the orchids without buds can be fertilized once, and then burned again half a month later.

During the sprouting period of young buds and new roots of ②, more nutrients are required. Fertilizer can be applied twice in sunny days, more than ten days apart each time.

During the "Meiyu" period of ③, seed grass grows very fast, breaking out of the ground one by one, new roots are derived, and flower buds germinate. At this time, fertilizers can be applied once or twice on a sunny day, each time more than ten days apart.

When ④ "Lesser Heat" is as thin as bluegrass, he is forced to apply light fertilizer for once.

During the period from "it dew" to "the Autumn Equinox" in ⑤, the new leaves grow and the buds have layers and shells. At this time, light fertilizer can be applied for the last time, but it must be thinner and more.

After the ⑥ "Cold Dew", the roots, leaves and buds have all come a long way. If there is a "autumn pole" (that is, it grows into a new single after autumn), it can be properly refertilized. (Lin Qingde, Mu Wei)
