1. Select short and excellent varieties.
There are many varieties of chrysanthemums. If you want to plant potted plants, you can choose some shorter varieties to plant. For example, table chrysanthemum has short varieties such as "Xu Tao" and "Ling Boxian". This kind of chrysanthemum is short and strong, with luxuriant leaves and bright flowers, short growth period and long flowering period, which is very suitable for potted viewing.
2. Don't cut it too early, and the cuttings should be short.
In order not to make chrysanthemum plants grow too tall, the cutting time can be postponed. The cutting time of chrysanthemum is the key factor to determine whether chrysanthemum can be dwarfed. Generally speaking, Chrysanthemum Tridentate can be suitable for cutting in June, and Chrysanthemum Monochamus can be suitable for cutting in July and August. Chrysanthemums cut in summer can be shorter10-20cm than those cut in spring, and many chrysanthemums can only bloom after two or three months.
In addition, the chrysanthemum branches used for cutting should not be too long and as short as possible. Many people will use 3-4 branches longer than 10cm as cuttings. In fact, they can be shorter and keep two nodes, one of which is rooted in the ground and the other is exposed. Two nodes are enough for cutting survival, and the cutting is short, which is more conducive to dwarfing chrysanthemum plants; You can also leave 3-4 knots, which are deeper when you cut into the soil, and only one knot can be exposed. Other buried stems can take root, more nodes can take root, and the plants will be stronger.
3, it is necessary to properly pick the heart, wipe the buds and sparse the buds.
Chrysanthemums should be picked in time, so as to break the top advantage and promote the growth of branches as much as possible. Otherwise, if there are few branches, the main branch will continue to rise and even become an "army of one branch", which will affect its flowering. According to the variety and plant growth, chrysanthemum usually needs to be pitted 2-4 times. In addition, the last time to remove the core should not be too late, otherwise it may cause chrysanthemum not to sprout or bud.
In addition, there may be many axillary buds in the strong seedling stage of chrysanthemum. In order to reduce nutrient consumption, it should be smoothed in time, otherwise too many branches will make the plants look chaotic. In addition, there may be lateral buds on the shoots under the terminal buds in the bud pregnancy stage of chrysanthemum, so these unnecessary buds should be removed to promote the hypertrophy of the terminal buds of chrysanthemum.
4. Control fertilizer and water
Chrysanthemum likes fertilizer, but too much fertilizer can easily lead to excessive growth and thin leaves, so it can't be used in excessive fertilization. Phosphorus and potassium fertilizer can be used as base fertilizer, and no fertilizer is applied at seedling stage. During the growing period, only 1-2 times of thin fertilizer is needed every month. After beginning of autumn, the amount of fertilizer can be increased, which can make the chrysanthemum more colorful and the flowering period longer. In addition, the water content should be well controlled, too many plants are easy to grow in white, and the water content should be enough to maintain the consumption of plants that day.
5, acupuncture dwarfing or dwarfing with hormones.
Some chrysanthemums will grow wildly during the growing period. In order to prevent plants from growing too fast and too high, we can pierce chrysanthemums with sterilized sewing needles or big heads. Chrysanthemums generally pierce the center of stems, and those that grow vigorously can pierce them directly. Note that the puncture site should be selected at the lower end of the leaf at the growth point, which can destroy some transportation tissues of chrysanthemum and inhibit the growth of chrysanthemum, thus limiting the growth height of chrysanthemum.
At the same time, chrysanthemum dwarfing hormone, such as Bijiu (B9) paclobutrazol, can also be used. , usually sprayed once every 7 ~ 10 days after the last pot. Pay attention to spraying at noon, when the temperature is high, it is easy to cause phytotoxicity.
Well, the little gardener introduced the measures to dwarf chrysanthemums here. Thanks for reading, and enjoy it!
