Planting Tips

Chapter 21 What are the common methods of flower sowing

Sowing is generally divided into two types: open field sowing and greenhouse sowing.The methods include withdrawal, drill and on-demand.

(1) The sowing method is often used for smaller seeds, such as aster, snapdragon, cineraria, cattail flower, etc.Before sowing, the soil should be finely flattened, and after 1-2 hours of watering, the seeds should be evenly spread on the border or in flower pots, and covered with fine soil after sowing so that the seeds are not visible.When sowing very small seeds, such as cattailwort, perennial primrose, gloxinia, rhododendron, etc., in order to prevent uneven spreading, the seeds can be mixed with a small amount of fine soil and then spread.For border sowing, it is best to cover with plastic film or reed curtains in spring to keep the bed soil moist.For those planted in pots, cover them with glass and newspapers to keep them moist and keep warm. If necessary, soak the pots with water, and try not to water them directly from above.

After the seedlings emerge, gradually remove the cover.

(2) Drill sowing method: make shallow furrows at a certain distance from the border or basin soil, and sow the seeds into the furrows to flatten them. Other management is the same as that of sowing.Drill sowing is mostly used for taproot flowers that are not suitable for transplantation or autumn sowing flowers in the open field, such as poppies, morning glory, poppy, impatiens, radish, straw chrysanthemum, etc.

(3) On-demand method Large seeds can be sown one by one to save seeds, such as mirabilis, nasturtium, sweet pea, etc. The thickness of the covering soil is equivalent to about 3 times the diameter of the seed.Regardless of the sowing method used, proper humidity, temperature and fresh air should be maintained after sowing.After the seeds germinate, the amount of watering should be appropriately reduced, and the light should be gradually increased. If the seeds are too dense, the seedlings should be planted in time to maintain ventilation and light transmission.When the seedlings grow to 2 to 3 true leaves, they are planted separately, and the transplant-resistant flowers can be transplanted 1 to 2 times, such as asters, impatiens, and a string of reds, and then planted in flower pots or flower beds.Some flowers are not resistant to transplantation, such as poppies, sweet peas, etc., it is best to use the direct seeding method or nutrient pots to raise seedlings.
