Forsythia suspensa is a wild or artificially cultivated Chinese herbal medicine plant, an evergreen tendril shrub, native to tropical America. It is an ornamental plant that can blossom in summer, autumn and winter, with beautiful tree posture and vigorous growth, and can blossom and bear fruit at the same time. So, do you know how to raise forsythia? Next, Uncle Gardener introduced the cultivation methods and precautions of Forsythia suspensa: 1. Soil: Forsythia suspensa seeds should be planted in sandy loam or loam with good drainage, deep soil layer and loose and fertile soil. Apply decomposed chicken manure, sheep manure 1000 kg, calcium superphosphate 50 kg, diammonium phosphate 30 kg every 667 square meters, plow and harrow to make it 100- 120 cm wide and 20-30 cm high. Cutting should choose sandy land with convenient irrigation and good air permeability. It is advisable to plant a gentle slope facing the wind and the sun. 2. Potting: Forsythia suspense can germinate about 10 day after sowing, and the germination rate is about 50%. Seedlings usually need to be cultivated for 2 years before they are born, so they should go to pots or gardens. Cuttings are carried out in late spring and early summer. Select 1~2-year-old shoots, cut them into 15 cm long, and insert them into wet sand bed. It takes about a month to take root, one and a half months to enter the nursery for cultivation, and then leave the nursery in the second or third year. Plastic surgery for bending branches will begin in the second year after the seedlings are born. Forsythia can bloom in summer, autumn and winter. 3. Temperature: Forsythia suspensa likes warm and humid environment, and the optimum growth temperature is 22-30℃, so it is a plant with low cold resistance. If you encounter long-term low temperature or sudden frost, plants are vulnerable to cold damage, and their safe wintering temperature is at least 5, so you should pay attention to cold protection. 4. Lighting: I like sunshine, and I am a little tolerant of shade. Even in hot summer, we should give enough light to grow and bear good fruit. During the growing period, try to receive sunlight, especially forsythia suspensa and forsythia suspensa. The stronger the sunshine, the brighter the golden color of its branches and leaves, and the brighter the markings on its leaves. When the light is insufficient, the color often fades and turns green, which makes the leaf color unsightly. 5. Watering: I like wet soil environment, but I am not tolerant of drought. During the growing period, especially in summer, it is necessary to fully water and keep the basin soil moist to meet the needs of plant growth and flowering. Waterproof and moisture-proof, watering should master "thousands of wet and white". But it can't be too wet or too stagnant. After the rainy season, it should be checked in time to dump the accumulated water in the basin. Water should be controlled in winter to keep the basin soil dry. 6. Fertilization: Because of the large growth, it can blossom and bear fruit continuously from summer to winter under suitable conditions, and it needs a lot of nutrients. Therefore, it is necessary to constantly supplement nutrients and strengthen fertilizer and water management during the growth period. Nitrogen fertilizer should be topdressing every half month in spring to promote the growth of branches and leaves. In the summer and autumn after pregnancy, the fertilizer mainly containing phosphorus and potassium should be topdressing once every half month to promote continuous flowering and fruiting, so that the flowers are lush, colorful and fruitful. Even if plants are moved indoors in autumn, it is still necessary to apply phosphorus and potassium fertilizer appropriately to increase the color of fruits and prolong the observation time of fruits. For tree species with mottled leaves, attention should be paid to the application of phosphorus and potassium fertilizer throughout the growth period to make their leaves bright and beautiful. Forsythia will blossom and bear fruit at the same time. 7. Pruning: Extremely resistant to pruning. In spring, plants are pruned by turning over flowerpots. Remove too dense weak branches, cross branches, parallel branches, pests and diseases, and cut the remaining branches short to keep the plants well ventilated and transparent, and the plant shape is round. During the growing period, when the branches grow unevenly, they can be adjusted by pinching and pruning. If fruit is not needed after flowering, the flowering inflorescence can be C.
