The seeds of bosju have the ability of self sowing. Once planted, a large number of self sown seedlings will be produced. With a little protection, they can bloom as usual. It can be sown in the open bed in the middle of April. If the temperature is suitable for about 6-7 days, the seedlings can be unearthed.
From July to August, when sown, it will bloom in October, and the plants are short, strong and tidy.
When the seedlings have 4-5 true leaves, they can be transplanted, and the heart can be removed, or the seedlings can be intercropped after direct seeding. If the base fertilizer is applied to the planting land, there is no need to apply fertilizer again in the growth period. If the soil is too rich, the branches and leaves are easy to grow in vain and the flowering is reduced.
It is not easy for the flower to bear fruit during the high temperature period from July to August. The seeds are easy to fall off after ripening and should be collected in the early morning. Bosju is a short sunshine plant, which is often leafy and flowered less in spring, and short, neat and blooming in summer.
The cutting should be carried out in warm May, and can bloom from June to July.
The stout top branch can be selected, and a section of 8 cm to 10 cm long can be cut as the cuttings. Three to five plants are planted in the flowerpot as a cluster. The basin should be buried in the soil, exposed to the ground for 4 cm to 5 cm, watered and shaded, and take root half a month later.
After rooting, thin liquid fertilizer was applied once every 15 days. When it was 15 cm long, the top buds were removed to promote more branches. If the fertilizer and water are properly controlled, flowers can be seen in about 45 days.
Whether seeding or cutting seedlings, they need to be dwarfed to a certain extent, in order to avoid windward collapse after the plant is formed.
When topping and coring, it is necessary to pay attention to the sharpness of the trimming tools to ensure the symmetry of the incision. The new terminal bud can be removed several times in succession, and the plant can be short, strong and healthy.
