How to propagate multi-head chrysanthemum and when to plant seeds

Article Catalog

Chrysanthemums are commonly propagated by cuttings. The best time for cutting is between May and June, when the high temperature has not yet come. The substrate can be prepared with rice bran and perlite in a ratio of 3:1. Choose good, strong cuttings as cuttings. The spacing between rows is about 3cm, insert one-third of the cuttings into the substrate, then compact it and spray enough water with a watering can. When the fibrous root length of the cutting seedlings is about 2cm, it can be planted shallowly in the pot. After the potting is completed, it needs to be placed in a cool place for 3-5 days before receiving light.

1. Propagation method

1. Prepare the substrate: It is best to use soilless substrate as the substrate. It can be prepared with rice bran and perlite, the best ratio is 3:1. Place the prepared substrate in a seedling container, level it and set aside. Because the cuttings grow using the cuttings' own nutrients, the substrate does not need to contain nutrients, and there is no need to apply base fertilizer.

2. Timing of cuttings: The best time is in May-June before the high temperature comes. The cutting period needs to be determined based on factors such as the length of seedling cultivation and the number of toppings. Generally, it takes about 2 weeks to raise seedlings on a soilless substrate, and about 20 days on a soil substrate. Then put the seedlings in the pot and slow them down for about 10 days before topping, and the first period is between July and August. Based on this, you can choose the best cutting period.

3. Branch selection: Select branches with good growth, robustness and no Branches infected with diseases and insect pests are used as cuttings. Generally, chrysanthemum plants are often used as cutting seedlings after being picked several times. The length of the cuttings should be 5-6 cm, and the leaves at the base of the cuttings should be removed. It should be noted that the harvested cuttings cannot be exposed to the sun. They need to be placed in a cool place and sprayed with water to keep them moist.

4. Cutting: When cutting, the spacing between rows should be about 3cm, and one-third of the cuttings should be inserted into the substrate. After inserting, use your fingers to gently press the matrix around the base so that it can be tightly combined with the matrix. After plugging it in, use a watering can to spray it with enough water.

5. Potting: After the cuttings take root and become seedlings, it is necessary Pot in time. When the fibrous roots are about 2cm long, it is most suitable for potting. When potting, avoid damaging the root system. Try to use smaller pots so that nutrients can be more concentrated. The upper pot needs to be planted shallowly, and the pot soil should not be filled all at once. Fill more than half of the pot. You can continue to fill the pot with soil as the plant grows. After the potting is completed, it needs to be placed in a cool place for about 3-5 days, and then moved to a sunny place for normal maintenance and management.

2. Sowing time

Bulls If chrysanthemums are propagated by seeds, the sowing time is mostly from February to April. Normally, flowers will bloom the same year they are sown. After sowing, soil moisture needs to be maintained and the temperature should be controlled at around 10-18°C for germination.
