Novice must plant: potted sunflower planting method

Sunflower seeds are large achenes with plump grains. Seed activity is strong, stress resistance is strong, seeding can be used seedling block, common peat, even common garden soil, without special seedling treatment. When sowing, insert sunflower seeds vertically into the sowing medium, tip down, and cover with soil about 1 to 2 cm. Keep the medium moist before emergence. It usually takes 3 to 7 days to emerge. Seed germination needs shade, appropriate soil cover helps to help germination when self-capping.

sowing

1. Seeds need to germinate before sowing. It is more practical to germinate with tissue paper. After soaking in water, the tissue paper covers the seeds. It can germinate in about 2 days. Of course, it can also be soaked in water. Generally, it is almost soaked overnight.

2, potted sunflower seeds are small, the top soil ability is relatively weak, sowing is not easy to be too deep, generally about 1 cm.

3. Cover soil after sowing and lightly suppress it. If seedlings are planted in winter and spring, they can be covered with film and kept warm to shorten the emergence time.

After germination, keep the medium moist and place in bright sunlight for management. Keep the environment and medium moist, can accept strong sunlight, insufficient light will grow.

If the seedlings are too dense, they can be thinned. Use toothpicks, tweezers and other fine objects to carefully remove the medium, remove the seedlings that need to be taken out, and transplant them into small bowls. During this period, if there is damage to the root system, it will not affect the growth of later plants.

colonization

After the seedlings grow 4 to 6 true leaves, they are planted. The pot diameter is 14CM (No. 5 middle pot), the planting material is 70% nutrient soil +30% vermiculite, and 30g rotten chicken manure is used as base fertilizer. The seedling block can be directly embedded into the pot. Small pots of false planting carefully take out seedlings with soil, with soil planted in new pots. Water it thoroughly.

After planting, it can be managed by full sunlight by standing in a shady and ventilated place for one day. Water every morning, sunflower growth fast, large water demand. The more leaves, the faster water consumption.
