After the beginning of autumn, it is the golden stage for the growth of chrysanthemum, so it is important to know how to care for autumn chrysanthemum. In management, it is necessary to grasp seven key points: timely moving indoors, changing pots in time, preparing good potting soil, splitting buds, paying attention to fertilization, controlling watering, etc.
1. Timely moving indoors
In order to make chrysanthemum bloom normally, do not rush to move it indoors in autumn. It should be exposed to low temperatures of about 5°C for about 10 days outdoors. During this period, water less and stop fertilizing. Appropriate sunlight should be provided during the day. Chrysanthemum can tolerate short-term low temperatures of about 0°C and short-term temperatures of about 5°C without being harmed. After the low-temperature treatment, move it indoors and care for it in a place without direct sunlight at temperatures of 10-15°C.
2. Changing pots in time
Raising large flowers in small pots is not conducive to plant growth. According to years of experience, chrysanthemum with 2-4 leaves should use a pot of 10 centimeters, 5-8 leaves a pot of 13 centimeters, 9-12 leaves a pot of 17 centimeters, 13-16 leaves a pot of 23 centimeters, and 17 or more leaves a pot of 27-33 centimeters. Do not use plastic pots, porcelain pots, or southern clay pots. It is best to use simple ceramic pots.
3. Preparing good potting soil
The best potting soil for chrysanthemum is a mixture of decayed leaf soil, river sand, and炉灰 (炉灰 =炉渣) in a ratio of 6:2:2. If there is no decayed leaf soil, you can also use a mixture of horse manure soil, river sand, and炉灰 in a ratio of 5:3:2. Do not use sticky soil or alkaline soil.
4. Splitting buds
When mature chrysanthemum grows buds and has 5-6 leaves, you should split the buds during the autumn pot change. Apply charcoal powder or fine炉灰 to the wound and then plant the separated plants in a new pot.
5. Paying attention to fertilization
In autumn, chrysanthemum grows vigorously and requires a large amount of fertilizer. In addition to placing some fermented soybean cake residue, bone meal, roasted seeds, or rabbit droppings as a base fertilizer at the bottom of the pot when changing pots, you can also place some roasted perilla seeds, sesame seeds, or pig blood meal on the top of the potting soil. If conditions permit, you can apply fermented soybean cake water or fishy water every half month.
6. Controlling watering
Compared to summer, the amount of watering for chrysanthemum in autumn should be relatively reduced, keeping the potting soil moist but not dry. Excessive watering can easily cause root rot.
7. Increasing sunlight
After the beginning of autumn, remove the sunshade facilities used in summer to let chrysanthemum get as much sunlight as possible. If the indoors are阴暗 with insufficient sunlight, you can also supplement with lights for 1-2 hours, with red light being the best, not white light.
