How to raise jasmine flowers that bloom three times a year
Jasmine is famous for its fragrance, and to achieve three blooms a year requires mastering scientific maintenance methods. This article will analyze in detail the management points corresponding to the three flowering periods, and combine them with specific seasonal characteristics to help you create a jasmine courtyard with endless flowers. Jasmine flowers have three flowering cycles to manage the first flowering period (June-July). Nutritional start. The first flowering period in summer requires the principle of "applying thin fertilizer frequently." It is recommended to use 1:1000 potassium dihydrogen phosphate solution and apply it every Tuesday and Friday evening. Combined with the watering method of "seeing dry and wet", replenishing water in the morning to keep the substrate moist, and using sunshade nets to adjust the growth environment below 30℃, the flowering period can be extended to 25 days. During the full flowering period (August), water and fertilizer control During the flowering period in August, the fertilizer concentration was increased to 1:800, and more decomposed soybean cake water was applied to supplement trace elements. The "dipping basin method" is used to keep the air humidity above 65%, and spray to cool down during the high temperature period at noon. Cut off residual flowers in time and retain 2 pairs of leaf nodes to stimulate the germination of new branches. At the end of flowering period (September to October), the maintenance transition period is gradually reduced to no fertilizer, and the "dry-wet alternating method" is used to control water, and the temperature difference between day and night is maintained at 8-10℃. The plastic pruning will be completed before winter, leaving 15-20cm of the main stem, and cooperating with the rhizosphere soil for cold protection to reserve energy for the next year's flowering. Acidic soil (pH 5.5 -6.5) is the key factor in four-season maintenance. Pine needle soil is mixed into when changing pots every spring. Light management follows the principle of "full sunshine in winter and spring and half shade in summer." Regularly use iron chelate to prevent yellow leaf disease and keep the leaves green and oily.
By accurately grasping the water and fertilizer ratio, temperature and humidity control and pruning timing during the three flowering periods, and cooperating with basic maintenance throughout the year, the ornamental effect of "three seasons fragrance" of jasmine flowers can be achieved. It is recommended to establish a maintenance log to record each flowering time and maintenance details, and gradually form a personalized management plan.
