After planting a bunch of red plants, place them in the shade for 3 days to slow down the seedlings. Then put it in the sun to ensure sufficient light. To facilitate the control of light intensity, a suggested scaffold can be built above the flowerpot. When the light is too strong, especially at noon in summer, it should be shaded by 50%. Once it is in low temperature, it needs to be covered with plastic film for proper heat preservation, which can be done at night or in rainy days.
A string of red like humid environment, should spray water once a day, except rainy days. When watering, the difference between ground temperature and water temperature shall not exceed 5 ℃. When the temperature is high, spray water to the surrounding environment frequently to reduce the temperature and increase the air humidity. Clean branches and leaves regularly to improve photosynthesis, once every 15-20 days.
The soil provides an important guarantee for the growth and development of flowers, but it does not guarantee the robust growth of plants. It is far from enough to rely on the little water, fertilizer and air in the soil. It is also necessary to apply fertilizer outside the roots. The specific methods are as follows:
After potting for a week, apply fertilizer outside the root once. Spray spray once a day after three days. Urea, potassium dihydrogen phosphate and a small amount of superphosphate are selected as fertilizer. The spraying time is in the early morning and evening.
After that, watering and fertilization will be combined in the maintenance, and fertilization will be carried out outside the root 8-12 hours after watering. Pay attention to the construction in windy days or when the light is strong.
Sowing in different seasons, flowering time is also different. Sowing in spring, flowering in autumn; sowing in Greenhouse in autumn, flowering in April to May of the next year. The flowering period can be controlled in the following ways:
Cut off the shoot of flower bud in time, and postpone the flowering period appropriately.
After each flower failure, remove the remaining flowers in time, strengthen the management of water and fertilizer, a bunch of red can re branch and bloom, and extend the flowering period.
A bunch of potted red plants need to be topped three times after transplanting to inhibit their growth and promote the germination of lateral buds. In this way, the plants are short and strong with more flower heads.
