Time and key points of fertilization

After the orchid leaves the house in early spring, around the "Qingming Festival", choose a sunny day, first irrigate the orchids without buds, mainly thin. At an interval of more than half a month, water it again. Those who have blossomed have to wait for more than ten days before they can apply fertilizer. If you want to turn the basin and change the soil, you can put some rotten sediment at the bottom of the basin, and then cover the mud layer to plant on the root base, so that there is no need to apply fertilizer in the same year. In the period of bud and new root germination, more nutrients are required. If not given proper fertilization, the soil will be broken in the grass and the new leaves will become thin, and it is not easy to produce flowers, or affect the growth and flower size of next year. Entering the Meiyu period, the 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. Lesser Heat, such as bluegrass, thin and weak, will have to apply light fertilizer once. During the period from White Dew to the Autumn Equinox, due to the growth of most of the new leaves and the complete capsid of each layer of the bud, light fertilizer can be applied for the last time, but it must be thinner and less than before.

Fertilizing should be carried out in the morning and evening. If it is a little solid on the basin surface, first gently loosen it with a blunt bamboo piece along the edge of the basin, do not touch the Langen. If the leaf is thin and light in color, it is a phenomenon of lack of fertilizer, which can appropriately increase the frequency of topdressing or increase the concentration. Fertilization should be based on the principle of small amount, thin, frequently irrigated and timely.
