① select healthy twigs, only keep 2 or 3 leaves at the top, and remove all others.
Cut off the long branches below and keep the length of about 8cm above.
Prepare sand in the basin and poke a hole with chopsticks.
③ carefully insert the chrysanthemum branches, and gently press down on the surrounding sand.
It can also be bagged for moisture. Wet the sand with a watering can. About 2 weeks, the chrysanthemum took root.
Remove the chrysanthemum from the basin and clean up the soil on the root system.
According to the natural shape of the root system, the plants can be separated.
Prepare a new flowerpot and put it on again!
Generally, chrysanthemum will pick the heart 2 to 3 times, in order to promote the germination of lateral branches, so as to let the flowers bloom more!
When the chrysanthemum seedling grows to about 10cm, the first heart picking can be carried out. When the heart picking, only 3-5 leaves at the base of the plant can be left, and the buds on it can be pinched off.
After the new branches grow out of 5 to 6 leaves, you can carry out the second heartlifting!
Chrysanthemum is a short day plant, too much light time every day, will affect the flower bud differentiation of chrysanthemum. Therefore, if the chrysanthemum does not bloom, you can put the chrysanthemum into a black house.
Make sure that the light time of chrysanthemum is less than 12 hours a day.
Besides the time of illumination, there is also the temperature difference. Only when the temperature difference is about 10 ℃ can the flower bud be gestated.
Therefore, conditional flower friend had better put chrysanthemum in outdoor culture, to increase the temperature difference between day and night
It is mainly lack of phosphorus and potassium elements. Therefore, potassium dihydrogen phosphate can be sprayed at a ratio of 1:1000, once a week, three times in a row, and it is almost ready to conceive.
First, take the chrysanthemum out of the flowerpot and clean up the soil on the root system.
② carefully check the root system of chrysanthemum and cut off the rotten and blackened root system with sharp scissors.
③ soak the cut of Chrysanthemum in carbendazim solution for about 20 minutes and sterilize it. Then take it out and put it in a cool and ventilated place to dry.
④ prepare new soil and flowerpot, do not use the former one, to avoid rotting again. Put a layer of ceramsite on the bottom of the flowerpot, pervious water, and then fill the flowerpot.
1. Soil: Chrysanthemum likes loose, fertile and slightly acid soil with good drainage, so the suitable soil ratio is: 6 parts of saprophytic soil, 3 parts of sandy loam, 1 part of cake fertilizer residue.
2. Watering: Chrysanthemum likes to water, about once every 2-3 days, in the morning or at night.
3. Fertilization: after the beginning of autumn, every 7-8 days, use the liquid fertilizer of potassium phosphate, or 0.1% potassium dihydrogen phosphate, or 30% fertilizer water of the rotten cake.
4. Light: chrysanthemum is a short sunshine plant. It can bloom only after 12 hours of light every day. Note that the light is not good either. If the house is very bright at night, cover a paper box for chrysanthemum to block the light!
In fact, it's good to cut off the chrysanthemums that have already blossomed. After all, it's a waste of nutrition to stay on them.
When pruning, cut all the chrysanthemums from the root up about 2cm. Note that the bottom of the sprouting seedlings from the perennial root is not need to be removed, it has a strong cold resistance, overwintering is not a problem!
