Why did Chrysanthemum morifolium bloom for one day and get along with it for another?
Cultivation and management of hibiscus.
Fusang grows vigorously, has a long flowering period and needs sufficient nutrients, so the soil in the basin is very fertile. Pot soil preparation of hibiscus should be given different proportions according to its growth stage. After the cuttings survive, they should be placed in a 3-inch pot, and the pot soil can be prepared with 7 parts of garden soil, 7 parts of manure 1 part and 7 parts of sand 1 part. Put it in the shade after serving. After delaying seedling 10- 15 days, move to the sunny place. Water 1-2 times a day according to the dry and wet climate. After growing for more than 2 months, it can be replaced with a 5-inch pot. Pot soil should be prepared with 8 parts garden soil and 2 parts dung soil, and some cake fertilizer powder should be put at the bottom as base fertilizer when changing pots.
When the seedlings grow to a height of 20 cm, the first coring is carried out to promote the germination of the lower axillary buds. In the process of sprouting and forming branches at the base, 3-4 branches of new technology with similar growth intensity and balanced distribution are selected, and the remaining axillary buds are erased to concentrate nutrients for the growth of the remaining branches.
In the spring of the next year, it was moved to outdoor culture, so it could be replaced with an 8-inch pot. Pot soil can be 6 parts garden soil and 4 parts dung soil, and the bottom of the pot is made of hoof crumbs and bone meal as base fertilizer. At the same time, each branch is left about 10 cm for short cutting. After germination, two branches are left in each branch, and the other branches are erased.
In the third spring, there is no need to change pots, but short scissors are needed. The principle of pruning is to remove the weak and retain the strong, to remove the dense and retain the fine, so that the plant cluster is full and symmetrical and a beautiful skeleton is cultivated. In the spring of the fourth year and every two years thereafter, gradually replace the pots with 10- 12-inch pots, with 6 parts of garden soil and 4 parts of manure. When changing pots, shake off the old soil at the edge and trim some old roots.
Fertilizer and water management during hibiscus growth: water every morning and evening in midsummer 1 time; In spring and autumn, if the basin is dry in the morning, you can add a small amount of water, and generally pour 1 times of water in the afternoon. Attention should also be paid to spraying water on the leaves during the growth period to improve the air humidity, especially on the balcony. Water should be watered according to the wintering situation in winter. If you overwinter in the greenhouse, water it every 1-2 days 1 time. If you overwinter indoors, water 1 time every 5-7 days, so the amount of water should be small. Topdressing in the growth period is generally 1 double liquid fertilizer once every 15-20 days; Fertilization should be light when the plants are young, and the times should be frequent. Fertilization should be thick for adult plants, and the interval can be longer. When overwintering indoors, sprinkle a thin layer of dry fertilizer on the surface of the basin soil. The fertilizer can be coarse cake powder or sauce residue powder.
