How to Sow Jasmine Seeds
Jasmine is loved by gardening enthusiasts for its elegant fragrance. Mastering the correct sowing method is key to cultivating healthy plants. This article will systematically analyze the entire process of planting jasmine, from practical sowing techniques to seasonal control.
The Four Steps of Sowing Jasmine Seeds
Seed Pretreatment Techniques
High-quality seed sources are the first step to success: choose seeds that are plump and evenly colored from the current season, as older seeds can reduce germination rates by over 60%. Use the warm water activation method by soaking the seeds in 40°C water for 5 hours to soften the seed coat and promote germination.
Nutrient Substrate Configuration
It is recommended to use a golden ratio of peat soil: perlite: decomposed leaf soil = 5:3:2, with a pH value stable between 5.5-6.5. The substrate can be disinfected using the sunlight exposure method, spreading 3cm thick and exposing it to sunlight for 48 hours to effectively kill pests and eggs.
Sowing Operation Standards
Use the dot sowing method with a 2cm spacing, and follow the 'three times the seed diameter rule' for covering soil thickness. After sowing, use a mist sprayer to moisten, avoiding water冲击 that could cause seed displacement. It is recommended to use a seedling box to create a microenvironment, keeping humidity between 70%-80%.
Seedling Management Essentials
Maintain a constant temperature of 20-25°C during the germination stage, using a shade net with 50% light transmission. After the true leaves spread, supplement with 1/4 concentration of seaweed fertilizer weekly, combined with 4 hours of scattered light daily. Be cautious of damping-off disease and regularly spray a 800x solution of benomyl.
Scientific Control of Sowing Timing
In the Yangtze River Valley, it is best to sow between Qingming and Lixia, when the ground temperature is stable above 18°C. In southern regions, it can be delayed until before the plum rain season, while in northern greenhouses, it is possible to sow throughout the year. Experimental data shows that seedlings sown in late April have a 23% higher survival rate than those sown in summer.
Mastering the sowing nodes and care techniques, combined with regular pruning and shaping, jasmine can form a 30cm canopy in the same year. It is recommended to develop a planting calendar based on regional climate characteristics, regularly test the soil EC value, and create a fragrant jasmine garden.
