1. Master growth habits, and pay attention to light and water.
Yushu has low requirements for soil. Yushu likes warmth and should be placed in a sunny place. It can also grow well under the condition of indoor scattered light. Avoid direct sunlight. Remember that summer exposure can cause leaves to shrink and turn yellow. It should be planted on fertile sandy soil with good drainage. Yushu is suitable for growing at a temperature of 20 to 30 degrees. Spring and autumn belong to the growing period, so we should get more sunshine. When the temperature is too high in summer, keep out the sun and don't let the sun shine directly on it. When the temperature reaches above 35 degrees Celsius, the growth of Yushu will be delayed or stopped. Water 2-3 times a week during the growing period, and strictly control watering in hot and humid July and August. Poor ventilation or excessive water shortage in midsummer can also cause leaves to turn yellow and fall off, so they should be maintained in a semi-shady place. After autumn, watering gradually decreases. When cultivating outdoors, avoid heavy rain, or there will be too much water in the roots, which will easily lead to the death of rotten roots. When changing pots every year or putting houses in autumn, attention should be paid to shaping and pruning to make the plant shape more elegant.
2. Pay attention to pruning management and strengthen pest control.
Yushu likes to fertilize, and it should be fertilized 2-3 times a month during the growing period to keep sufficient fertilizer in the soil. After Yushu sleeps in spring, change the pot soil once. When changing the pot soil, organic fertilizer and chicken and duck manure are added to the soil as base fertilizer. When changing pots in spring, we should apply foot fertilizer to the soil so that Yushu can grow more beautifully. Yushu is pruned according to his hobby. He likes to have a round and plump crown. When pruning, he cut off the long branches and overlapped the crowded branches too much, so that the external crown of the plant was complete and the internal branches were properly dense. The main pests and diseases in Yushu are leaf spot, anthracnose, scale insects and so on. If diseases are found, it is suggested to clean the damaged leaves in time and deal with them in time to prevent the spread of pests. The main diseases are carbon spot and leaf spot, and 70% thiophanate-methyl wettable powder 1000 times can be sprayed. The indoor ventilation is poor, and the stems and leaves are vulnerable to scale insects. Use 40% omethoate emulsion 1000 times solution for spray killing.
3. Fertilize flowers in time to promote flowers to flourish.
No flowering is mainly caused by insufficient light, unreasonable watering and fertilization and unsuitable soil. We can make corresponding adjustments according to the specific situation, and strive to make Yushu blossom earlier. In order to make Yushu blossom, we can appropriately increase the light for Yushu, with sufficient light in spring, autumn and winter, and properly shade it when it is hot in summer to prevent Yushu leaves from being sunburned. Because we know that if we want Yushu to blossom, we must first have light. In order to make Yushu blossom earlier, phosphorus and potassium fertilizer or potassium dihydrogen phosphate water-soluble fertilizer can be applied to Yushu in spring. Applying phosphorus and potassium fertilizer to Yushu can be applied once every 65,438+00 ~ 65,438+05 days, or the NPK compound fertilizer with the ratio of 65,438+0: 65,438+0 can also make Yushu flourish and achieve the effect of flowering and bursting pots.
