What soil is Jasmine suitable for growing in?
As a famous traditional flower in China, jasmine is widely loved for its white and fragrant flowers. If you want to grow luxuriant jasmine, mastering soil characteristics and maintenance points is the key. This article will systematically analyze the secret of jasmine cultivation from soil selection to daily management. Three major factors in Jasmine soil selection 1. The loose and breathable substrate structure Jasmine root system is fleshy and requires a soil porosity of>30%. It is recommended to use matrix particles with a particle size of 0.5-2mm, and 30% perlite or coarse river sand can be added to improve clayey soil. The basin needs to be turned and replaced every two years to prevent hardening from affecting root respiration. 2. Fertility characteristics of continuous fertilizer supply In addition to the base fertilizer, phosphorus and potassium fertilizers should be top-applied every 15 days during the growing season. It is recommended to mix bone meal (ratio of nitrogen, phosphorus and potassium 3-15-0) with decomposed sheep manure (containing 24% organic matter) at a ratio of 1:3, which is particularly effective during the flower bud differentiation period. 3. The soil pH value is regularly tested in a stable and acidic pH environment to maintain the pH value in the range of 5.5-6.5. It can be adjusted by watering 1:1000 ferrous sulfate solution every month, or mixing 5% pine needle soil to maintain acidity. Alkaline soil can easily cause iron-deficiency yellow leaf disease. The classic ratio recommended for the scientific soil blending plan of jasmine flowers is 40% humus soil +30% garden soil +20% perlite +10% decomposed manure. Increase the humus soil to 50% during the seedling period, and 5% rice hull carbon can be added to three-year-old piles to enhance drainage. Pay attention to layered filling: 3cm ceramite cushion at the bottom of the basin, mixed matrix in the middle layer, and 2cm pure legular soil on the top layer for root protection. Jasmine flower system maintenance guidelines 1. Light and temperature management requires ≥6 hours of direct light every day, and appropriate shade at noon in summer. The overwintering temperature remains at 10-15℃, and temperatures below 5℃ will cause freezing damage. Full sunshine maintenance can be carried out in spring and autumn. 2. The coordinated control of water and fertilizer follows the principle of "seeing dry, seeing wet", and 2cm of topsoil is dried and poured thoroughly. Add potassium dihydrogen phosphate (800 times solution) before flowering, and replenish nitrogen fertilizer in time after flowering. Stop fertilizer and control water during winter dormancy. 3. Pruning and flower promotion techniques Retain 2 pairs of leaves after flowering and re-cut them to promote new branches. Plastic pruning is carried out in March every year to remove weak branches and crossing branches to keep the plant type transparent. Combined with pickings, the amount of flowers can be increased by 30%.
Through scientific soil management and refined maintenance, jasmine flowers can become frequent visitors to the balcony. Remember the three key tips of regular soil change, precise fertilization, and reasonable pruning. Even novices can make jasmine bloom every year. It is recommended to test soil conditions quarterly and adjust maintenance plans in a timely manner.
