Culture methods and matters needing attention of two-color jasmine

Sowing and reproduction

Seed selection: first of all, the seeds should be selected before sowing. Whether the seeds are good or not is directly related to the success of sowing. 1. It is best to choose the seeds harvested in the same year. The longer the seed is preserved, the lower the germination rate is.

2. Choose full seeds without defective or deformed seeds.

3. Select the seeds free from diseases and insect pests.

Disinfection: disinfection includes two concepts, one refers to the disinfection of seeds, and the other refers to the disinfection of sowing substrates. Families often soak the seeds in hot water at about 60 degrees Celsius for a quarter of an hour, and then use warm hot water to promote germination for 12 hours. The best way to disinfect the substrate used for sowing is to stir-fry it in a pan so that any diseases and insects can be scalded to death.

Sprouting: soak the seeds in warm hot water (the temperature is about the same as facial wash) for 12 to 24 hours until the seeds absorb water and expand. For common seeds that germinate easily, this practice does not have to be done.

Sowing: for small seeds that are difficult to pick up by hand or other harness, wet the end of the toothpick with water, stick the seed-seed-grain to the surface of the matrix, cover the substrate 1 cm thick, and then put the seeding flowerpot into the water, the depth of the water is 1x2cm 2ppm 3, let the water soak up slowly (this method is called "pot immersion")
