The planting of chrysanthemum

Chrysanthemum should be planted in loose, fertile and permeable slightly acidic sandy soil, and phosphate and potash fertilizer can be properly applied as base fertilizer, if the leaves are small and yellow, urea can be sprayed appropriately, and the Beginning of Autumn should ensure sufficient fertilizer and water at the flowering stage. appropriate application of phosphorus and potassium fertilizer can prolong the flowering period. It is very important to control the water of potted chrysanthemum. When the chrysanthemum grows strongly, it is necessary to change the pot, pick the heart in time according to the growth situation in the later stage to promote the lateral branch, remove the axillary bud properly in the strong seedling stage, and cut off the side bud in the bud stage.

First, choose soil

When potted chrysanthemum is planted, it is suitable to use loose, fertile and permeable slightly acid sandy soil, so the soil of rotten plants can be used: garden soil: river sand, the ratio is 4: 4: 2, and the soil can be disinfected if possible.

II. Regular fertilization

1. When cultivating chrysanthemums, improper fertilization during the period will easily lead to overgrowth, and excessive fertilization will lead to sparse plant height and leaves, so the base fertilizer is suitable to use phosphate fertilizer and potash fertilizer, and topdressing in the later stage should not be too early. If there is a phenomenon of small and thin leaves and yellowing leaf color, 0.1% urea solution can be sprayed many times until the leaf color returns to green.

2. If there are symptoms such as lack of phosphate fertilizer and potash fertilizer, 0.2% potassium dihydrogen phosphate solution can be sprayed. After the Beginning of Autumn and before flowering, sufficient fertilizer and water should be ensured, and the concentration should be gradually increased. Appropriate application of phosphorus and potassium fertilizer can make the flower color bright and the florescence prolonged.

3. Proper water control

If you want chrysanthemums to grow densely, fertilized leaves, short and strong, and not barefoot, it is critical to control water during the period. When potted chrysanthemums are watered, they should be properly watered. Even in the vigorous growth period, it is only necessary to spray water on the leaves once a day in the morning and evening.

IV. Timely transplanting

The main results are as follows: 1. In the whole growth stage of chrysanthemum, the pots generally need to be changed 2-3 times, and the seedlings can be transplanted to small pots with a diameter of about 12cm for maintenance, strong seedlings can be transplanted to pots with diameters of about 15cm, and buds can be transplanted to pots with diameters of about 20cm before differentiation.

2. During the period, fertilizer can be applied according to the growth situation, which is beneficial to supplement the nutrients needed in each growth period. Do not raise small seedlings in large pots or large seedlings in small pots. If branches and leaves are found to grow vigorously in the later stage, part of the fibrous roots and persistent soil can be removed.

Fifth, pick the heart in time

Timely coring can not only promote more lateral branches, but also effectively depress plant height. The number and time of coring potted plants can be determined according to different shape selection arts. Generally, 4-7 chrysanthemums are retained, and 4-5 leaves are retained after chrysanthemum seedlings are planted. When the lateral branches grow 4-5 leaves, each side branch leaves 2-3 leaves, and then carry on the second coring.

6. Wiping buds and thinning buds

In the strong seedling stage of chrysanthemum, a lot of axillary buds will sprout, which need to be pinched with fingers in time, otherwise a lot of nutrients will be consumed, and a lot of lateral branches will sprout, showing that the chrysanthemum plant is disorganized, in the chrysanthemum bud stage, there are side buds on the branchlets under the top buds, which need to be cut off as soon as possible, which is helpful to promote the growth and hypertrophy of the top buds.
