Seed treatment of cedar

Cedar seeds are very small and there are many empty seeds, so we need to select seeds before sowing to remove the empty seeds. The seeds of cedar can be sown only after soaking and sprouting. Put the seeds of cedar in cold water for 96 hours. At this time, the seed soaking effect is the best. Disinfect the seeds after soaking. It is recommended to disinfect with 0.1% potassium permanganate. After 30 minutes of disinfection, rinse the seeds with clean water and dry the seeds. Do not sow wet seeds

Planting method of cedar

Planting cedar should be carried out before the spring equinox. Sowing should be carried out as early as possible, preferably in strips. The row spacing should be kept between 10-15 cm and the plant spacing should be kept between 4-5 cm. When sowing, the big head of the seed must be upward. After sowing, the seed should be covered with yellow heart soil or burnt mud ash. It is best to spread a thin layer of straw on yellow heart soil or burnt mud ash, and then spray water. The seeds will react after about 5 days, and the seeds will appear in about half a month

Seedling management of cedar
