Potted Jasmine Plant Cultivation Methods
The website tells everyone about the related knowledge of the woody flower Jasmine, the cultivation methods of potted Jasmine, and the specific introduction is as follows:
Potted Jasmine is easy to raise in spring, summer, and autumn, but not in winter. The cultivation methods of potted Jasmine can be summarized with the eight-character policy: plenty of water, plenty of fertilizer, high temperature and direct sunlight, as detailed below:
1. Plenty of Water: Jasmine has shallow roots with well-developed fibrous roots, lush branches and leaves. In summer, high temperatures cause high evaporation, and since Jasmine is not drought-resistant, the soil should not be too dry, but it should not be muddy either. It is best to use earthen pots, as plastic and porcelain pots have poor breathability and can be used as outer pots. The prerequisite for plenty of water is that the soil has a good granular structure, is loose, and breathable. The principle for watering is to alternate between dry and wet, watering thoroughly when dry. Note that dry does not mean completely dry and crispy.
2. Plenty of Fertilizer: Jasmine has a long growth cycle, high annual growth, and repeatedly sprouts branches and flowers, which consume nutrients quickly and require a lot of energy. Insufficient fertilizer will result in weak growth, thin branches, and few flowers. The prerequisite for plenty of fertilizer is the use of decomposed organic fertilizer as the main source, which is extremely important, such as rapeseed cake water (top-dressing) and water from poultry and fish innards (top-dressing), supplemented by chemical fertilizers like potassium dihydrogen phosphate. The method of fertilizing is to apply it in the evening on sunny days during the growing season, and then water back in the early morning the next day (this is crucial), doing this once a week during the growing season.
3. High Temperature and Direct Sunlight: Jasmine loves the sun and should not be overly shaded. With adequate water, full sun is best, as sufficient sunlight results in lush branches and leaves and more flowers, while low temperatures and shading result in thin leaves, few flowers, and thin branches. Additionally, moderate pruning is necessary before spring sprouting and after each batch of flowers to ensure proper branch spacing, concentrated nutrition, and reduced ineffective consumption.
Supplement: The issue of strengthening the plant during maintenance. After five years of growth, the main branches of Jasmine will age, and the upper branches will become weak with smaller flowers. Special attention should be paid to cultivating strong basal shoots, which have a robust growth and can be properly guided to replace the old main branches after a year of growth. The old branches should be cut off at the soil level to achieve the goal of updating the main branches and maintaining strong tree vigor.
The main pests during the growth of Jasmine include Jasmine leaf borer, cotton red spider mite, and flake scale insect.
1. Jasmine Leaf Borer: This is one of the main pests of Jasmine, whose larvae eat the leaves, flower buds, small branches, and new shoots of Jasmine. The bark of small branches will die after being eaten, and seedlings will die if infested, severely affecting the growth and flowering of Jasmine.
Control Methods: ① In winter or early spring, clear away the dead branches on the plant and the fallen leaves on the ground and burn them; ② thin out the leaves to improve ventilation; promptly manually catch and kill the eggs, larvae, and pupae on the leaves. ② During the growth of Jasmine, a 50% carbaryl wettable powder solution can be sprayed at a concentration of 6000 times, which has a good control effect.
2. Cotton Red Spider Mite: It can harm many flowers and many greenhouse plants. Jasmine is one of the common flowers affected. The leaves of affected flowers first show yellowish-white spots, which gradually turn red and spread to the entire leaf, causing leaf curling, yellowing, and falling off. The pest reproduces and spreads rapidly, causing serious harm to the growth and flowering of the plants.
Control Methods: During the period of red spider mite infestation, a 40% mitacloprid emulsion can be sprayed at a concentration of 1500-2000 times (or 50% mitacloprid wettable powder at 1500-2000 times, or 40% omethoate at 1000-1500 times) every 7 days, for 2-3 times, which works well. When spraying, be sure to spray the back of the leaves and the inner parts of the plant's middle and lower sections.
3. Flake Scale Insect: Occurs in several generations from April to October. The nymphs and larvae can crawl, while the adults remain fixed and absorb sap with a waxen shell. Control Methods: Use contact insecticides like chlorpyrifos during the nymph and larval stages for comprehensive spraying, and for adults with waxen shells, use systemic drugs like omethoate and a 20% petroleum emulsion that can dissolve the wax shell.
That is the detailed introduction of the cultivation methods of potted Jasmine, do you understand now?
