1、 Breeding method

1. Preparation of matrix: it is better to use soilless matrix. It can be prepared with rice husk and perlite in the ratio of 3:1. Place the prepared substrate in the seedling container and set it aside after leveling. Because cuttings grow with the nutrient supply of cuttings themselves, the matrix may not contain nutrients and there is no need to apply base fertilizer

2. Cutting time: the best time is from May to June, and the high temperature has not yet come. The cutting period should be determined according to the length of seedling raising time, the number of coring and other factors. Generally, it takes about 2 weeks to raise seedlings without soil substrate, and about 20 days with soil substrate. Then, the slow seedlings in the basin can be picked for about 10 days, and the head setting period is between July and August. Therefore, the best cutting time can be selected

3. Branch selection: select branches with good growth, strong and no diseases and insect pests as cuttings. Generally, chrysanthemum plants germinate after picking their hearts for many times as cutting seedlings. The length of cuttings should be 5-6 cm, and the leaves at the base of cuttings should be removed. It should be noted that the harvested cuttings should not be exposed to the sun. They should be placed in a cool place and sprayed with water to keep them moist

4. Cutting: when cutting, the row spacing shall be about 3cm, and one third of the cuttings shall be inserted into the matrix. After insertion, gently press the matrix around the base with your fingers so that it can be closely combined with the matrix. After inserting it, spray enough water with a watering can

5. Potting: after the cuttings take root and become seedlings, they need to be potted in time. When the length of fibrous root is about 2cm, it is most suitable to go to the basin. Avoid damaging the root system when putting on the pot. Try to choose a smaller pot for the flower pot, so that the nutrients can be more concentrated. Shallow planting is required for the upper basin. The basin soil should not be filled at one time. It can be filled into more than half of the basin. It can be filled again with the growth of plants. After the basin is finished, 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

If the multi headed chrysanthemum propagates with seeds, the sowing time is mostly from February to April. Normally, flowers can bloom in the year of sowing. After sowing, the soil humidity shall be maintained and the temperature shall be controlled at about 10-18 ℃ to germinate
