The care of Impatiens involves multiple aspects, including soil, light, temperature, moisture, fertilization, pruning, and pest control. The following are detailed answers to these aspects: 1. Soil requirements
Impatiens prefers fertile, moist, loose, and slightly acidic sandy loam soil. If the soil is too sticky or alkaline, humus soil, vermiculite, perlite, etc. can be added to improve the soil, or nutrient soil can be made by mixing humus soil, garden soil, and river sand in a ratio of 3:2:1. This soil is beneficial for the root growth and nutrient absorption of Impatiens balsamina. 2、 Lighting requirements
Impatiens prefers light and needs to be placed in a well lit area, receiving at least 4 hours of direct sunlight per day. But during high temperatures in summer, it is necessary to avoid direct sunlight exposure to prevent leaf burns. The placement of Impatiens can be adjusted appropriately according to seasonal and climatic changes to provide suitable lighting conditions. 3、 Temperature management
The suitable temperature for the growth of Impatiens is 16-26 ℃. During high temperatures in summer, it is necessary to take appropriate shading measures and maintain good ventilation to reduce temperature and prevent the occurrence of diseases. In winter, it is necessary to pay attention to keeping warm and keeping the room temperature above 10 ℃ to avoid freezing damage to plants. 4、 Water management
During the growth period, it is necessary to keep the soil moist and avoid being too dry or too wet. Watering should be done evenly, avoiding water accumulation, and paying attention to ventilation to prevent soil mold. The watering frequency can be adjusted according to the season and temperature. During high temperatures in summer, watering can be done once a day, while during low temperatures in winter, watering can be done every 5-7 days. 5、 Fertilization techniques
During the growth period, Impatiens requires timely fertilization. You can apply decomposed organic fertilizer or diluted liquid fertilizer every 10-15 days to provide sufficient nutrition. Before the flowering period, phosphorus and potassium fertilizers can be applied to promote flowering and prolong the flowering period. When fertilizing, avoid letting the fertilizer come into contact with the leaves and flowers to prevent burns. 6、 Pruning management
In order to maintain the beautiful shape of Impatiens and promote branching, timely pruning is necessary. During the seedling stage, heart picking treatment can be performed to promote branching growth. After the flowering period, timely cut off residual flowers and dead branches to facilitate the growth and flowering of new branches. 7、 Disease and pest control
The common diseases of Impatiens balsamina include powdery mildew, brown spot disease, gray mold, etc. They can be controlled by using pesticides such as powdery mildew, methyl tobramycin, chlorothalonil, or carbendazim. Common insect pests include aphids, red spider mites, thrips, and noctuids, which can be controlled using insecticides such as imidacloprid, imidacloprid, trichlorfon, imidacloprid, avermectin, chlorfenapyr, or fipronil. At the same time, the risk of disease and pest occurrence can be reduced by regularly cleaning dead leaves and weeds, keeping the surrounding environment clean, and implementing reasonable pruning and planting density control.
The care of Impatiens requires comprehensive consideration of multiple aspects, and only by taking the correct maintenance measures can Impatiens bloom healthily and beautifully.
