Basil is a plant with deep roots. Its roots can reach 50-100 cm into the soil. Therefore, it is advisable to choose a sandy loam with good drainage and rich and loose soil, and apply sufficient base fertilizer before planting. In family breeding, it's best to choose deep and wide flowerpots, so as to meet the root depth needs of basil.
Because of the short frost free period, it is necessary to raise seedlings in the greenhouse or greenhouse in order to harvest seeds. If you only eat tender leaves, you can raise seedlings or direct seeding. The seedling stage is usually sown in the middle and late of April.
Put the seeds into the gauze bag, shake off the water with force, cover with wet towel or gauze, keep warm and moisturize, and put them at the temperature of about 25 ℃ for germination. In the process of germination, rinse with water once a day to control the amount of seeds. If the amount of seeds is large, turn it 1-2 times a day to make the temperature balanced and the buds orderly. The temperature may be slightly higher in the early stage of germination, which can promote germination. When the buds are about to emerge (the seeds are about to open their mouths), the temperature shall be reduced by 3-5 ℃, so as to make the buds thick and tidy. After sprouting, in case of special weather, the buds can be moved to 5-10 ℃ to control the growth of buds and wait for sowing.
From March to April in the South and from late April to may in the north, the seeds shall be sown in the sunny morning. The nutritious soil shall be put into the sowing tray, and the seeds shall be watered thoroughly with hot water or warm water. After the water seeps, a layer of medicinal soil shall be sown, and the sprouted seeds shall be evenly sown in the tray, covered with 1cm thick medicinal soil, covered with plastic film, heat preservation and moisture preservation. After transplanting, water firmly to ensure the basin soil is wet.
Some flower friends have large balconies or flower beds, and they will plant a lot of basil. At this time, we should pay attention to the maintenance and management of seedlings. When the height of seedlings is 6-10 cm, the seedlings should be thinned and supplemented. Generally weed twice, the first time 10-20 days after emergence, shallow hoe topsoil. The second time is from early May to early June. When weeding, you can turn over the soil by the way to keep the soil loose. The seedlings are afraid of drought, so we should water them in time. Flower bed culture of flower friends, you can apply some chicken manure water, maintain nutrition supply.
