In the process of cultivating Torenia fournieri, the plants can be maintained in a brightly lit position during the growth period, and the temperature should be controlled at 15~30℃. In the spring, summer and autumn, the air humidity should be kept high, and the application should be 1~1 every month. Two times of decomposed cake fertilizer water, 1-2 times of phosphorus and potassium fertilizer can be applied in summer and autumn, and reasonable pruning and topping can be done.
Torenia fournieri is a typical positive plant with strong heat resistance. It needs to be maintained in a sunny environment during the growth period, and the temperature should be controlled at about 15 ~ 30 ℃, but the summer light is relatively strong, in order to avoid strong direct light can move the plants to a ventilated astigmatic place to facilitate the healthy growth of branches and leaves.
Torenia fournieri is a fertilizer-loving plant. During the growth period, liquid fertilizer is applied 1 to 2 times a month, mainly with decomposed cake fertilizer water. In summer and autumn, the phosphorus and potassium fertilizer can be topdressed 1 to 2 times according to the growth of the plant. The amount of nitrogen fertilizer is to avoid excessive growth. After fertilization, a proper amount of water should be poured in to keep the pot soil moist.
Pruning is one of the breeding methods and precautions of Torenia fournieri. When there are 5 true leaves at the young stage, the first topping is required to promote the growth of more branches, and then according to the plant's growth should be thinned and short-cut, and old branches and dead branches should be cut off together to facilitate the beauty of the plant shape.
Torenia fournieri prefers to grow in a high-humidity environment. It needs to maintain a high air humidity during spring and summer, mainly by atomization or spraying. In summer, it is also combined with watering for soil loosening and weeding. To promote the concentration of nutrients in the roots.
Torenia fournieri is susceptible to grief, powdery mildew, leaf spot, aphids and other hazards in the seedling stage. At this time, the interval of watering should be increased, and the diseased plants should be cut off and destroyed, and then the corresponding chlorophyll mancozeb solution is sprayed for prevention.
