First, the five-step pruning method of chrysanthemum 1, pruning axillary buds
In the strong seedling stage of chrysanthemum, its axillary buds grow vigorously, and too many axillary buds will make chrysanthemum consume nutrients quickly and cannot grow normally. We need to cut off the extra axillary buds with scissors, just like the illustration of chrysanthemum pruning method above, to avoid the loss of nutrients and the loss of aesthetic feeling of chrysanthemum plants.
2. Choose your heart in time
Chrysanthemum grows vigorously, so it is necessary to control the height of chrysanthemum and carry out core removal. Pick it in three times. For the first time, after the height of chrysanthemum has exceeded 10 cm, the extra branches and leaves of chrysanthemum are picked, leaving only 4-5 leaves at the bottom to continue to grow. The second time was in mid-August to cut off the redundant branches on the side branches, leaving only 2 ~ 3 leaves. The third time is to cut off vigorous, weak and redundant branches in early autumn to keep the beauty of chrysanthemum plants.
3. Properly sparse buds
In the budding stage of chrysanthemum, in addition to the soybean-grain-sized buds at the top, small lateral buds may grow next to them. In order to make chrysanthemums bloom bigger and more beautiful, we usually need to use tweezers to cut off excess side buds in the morning to sparse them. Pay attention to leave a spare bud when thinning the bud to prevent the terminal bud from blooming, and then cut off the left bud after the terminal bud blooms.
4. bloom was cut and trimmed.
During the flowering of chrysanthemum, it is necessary to cut off the flowering branches in time, and pay attention to pruning from the roots when cutting off the branches. When the flowering period of the whole chrysanthemum has passed and it no longer blooms, we need to cut off the withered and old parts of the stems in the pot to keep the potted plants beautiful.
5, pruning overwintering
Chrysanthemums need to be prepared for winter after flowering, and then wait until the next year. When we cut off the old branches, we need to pay attention to leaving the perennial roots. The seedlings growing next to the perennial roots will survive better and have stronger vitality in the coming year.
Two, chrysanthemum pruning 1 three points for attention, cleaning and disinfection
When pruning chrysanthemums, it is necessary to keep the environment clean and hygienic, so as to avoid chrysanthemum infection caused by environmental pollution after pruning, which will lead to chrysanthemum disease. At the same time, our pruning tools also need to be disinfected by boiling water, and then dried for pruning. Pay attention to make the incision as smooth as possible when trimming.
2. Trim height
When pruning the branches of chrysanthemum, it is mainly to prune the branches higher than chrysanthemum, and try not to prune the branches that are too low. If you prune the low branches near the roots at will, the plants may grow slowly. When pruning at the same time, you can't cut off the nodes on the branches, so you need to pay attention to pruning above the nodes.
Step 3 water properly
After pruning the chrysanthemums, we need to control watering. The branches of chrysanthemum are reduced, and the demand for water is also reduced appropriately. So we need to reduce the amount of water when watering. Generally, we only need to spray chrysanthemum leaves with a spray to keep the air moist.
Three, chrysanthemum disease control 1, rust
Once chrysanthemum is infected with rust, its stems and leaves will be greatly damaged. Facing the symptoms of chrysanthemum rust, we can choose to spray 500 times of 65/ 100 zineb wettable powder every half month or so, which can be cured generally for 2 ~ 3 times.
2. Black spot disease
Chrysanthemum black spot disease will cause a large area of irregular black spots on its leaves, which will lead to plant death in severe cases. In the face of the symptoms of chrysanthemum black spot disease, we can remove the damaged leaves first, and then spray 1/2 bordeaux solution for prevention and treatment, and it can be cured after 3 ~ 4 times.
3. Gray mold
Gray mold of chrysanthemum will damage its flowers, leaves and stems to some extent, and skin rot will appear on its plants. We can choose to spray 500 times of 65/ 100 zineb wettable powder 1 time, 1 ~ 2 times a week to cure the botrytis cinerea.
Conclusion: We know that it is necessary to prune chrysanthemums in time to keep them beautiful. As long as the five steps of axillary bud, core removal, bud thinning, pruning and wintering are achieved, beautiful chrysanthemum potted plants can be pruned.
