Pinus NIGRA

Sowing and germination

Seeds are stratified for 30 days in a cold environment at a temperature of 4-5°C. At home, the seeds are placed in the refrigerator. Before planting, the seeds are soaked in hot water for 24 hours and in any growth stimulant for 2 hours, then sown to a depth of about 7 mm and sprinkled with a layer of soil. They are moistened with a spray bottle, covered with film and germinated in the light at a temperature of 18-22°C. The seedlings need ventilation. It is necessary to avoid waterlogging and drying out of crops. Seeds can germinate from 3 weeks to 2 months.
