In the propagation of black grass, it is generally based on sowing propagation, it is not very easy to sow plants.
When sowing black grass, it is mainly planted in spring. In some areas in the south, it can be sown in autumn. Generally, it can germinate at 15 ℃ - 20 ℃ for about half a month.
The life of black seeded grass in sowing can be directly sown, but the effect will be better after germination. The seeds of black seeded grass are accelerated with paper towels. Generally, it takes about 1 week to accelerate germination. After germination, they can be seeded into the soil, but germination is relatively slow
When sowing black seed grass, we should pay attention to the fact that black seed grass is more photophobic, so when sowing, we should pay attention to shade and avoid the light before germination. If the light is too strong, it may not germinate.
The seed propagation germination of black grass is slow, and needs more careful care, so it is not suitable for novice seed
In general, the germination of fresh seeds will be faster, germination rate is also relatively better.
The seedlings of black grass are not transplantable, so after sowing, it's better not to transplant easily
If the black grass is broadcast live in the open, the flowering period will be later, and the flowering time will not be long
