Planting time
This kind of flower blooms relatively early. It usually blooms in April. Therefore, friends who did not plant in early spring can choose to wait until autumn, because the temperature in autumn is also more suitable for their growth. They are relatively cold resistant, and the most suitable temperature for budding is 15-20 ℃. However, if you choose to start operation in spring, you can blossom in three months p>
Planting steps
Preparation of matrix
Before sowing, the substrate must be selected well, and the selected substrate must have better drainage capacity, because this kind of flowers avoid waterlogging. If the drainage capacity is not good, it is easy to rot their roots and even lead to the death of the whole plant. A small amount of fertilizer can be added when preparing the substrate, so that they will not grow poorly due to too little fertilizer when they first grow p>
Sow
The vernalized seeds can be directly placed in the prepared nutrient soil, but the nutrient soil should be soaked in advance. Just sow the seeds on the surface without burying them too deep. Buried too deep in the soil will certainly affect their germination speed, and may even prevent them from sprouting p>
Film covering
After sowing, a layer of plastic cloth shall be covered on the substrate, which shall be similar to fresh-keeping film and shall be transparent and not too thick. Film mulching can not only maintain the temperature, but also maintain the humidity. When the seedlings grow two real leaves, the film can be removed. However, the surrounding environment should also be maintained at about 20 ℃ p>
Tips
If it is eroded by aphids during planting, certain measures should be taken. If there are not many insects when they are just found, they can be directly removed by hand and then sprayed with appropriate drugs p>
