1. Breeding temperatureUsually, it is difficult to accurately adjust the temperature during home breeding, so as long as the temperature is around 10-30℃, it will be fine. If conditions permit, the temperature can be maintained at 18℃ right after the plants are potted, and then lowered to around 15℃ after about a month of cultivation. The temperature during the winter should be above 5℃. If it is too low, frost damage will occur. 2. Sufficient lightIt is a plant that likes sunlight, and its light needs should be met during both the growing period and the flowering period. It can accept direct sunlight in spring, autumn and winter, but after entering summer, you should pay attention to shade at noon. In addition, the temperature should be lowered appropriately and windows should be opened more often in summer. 3. Water ManagementAppropriate humidity in the breeding environment will help the plant grow, but if there is too much water or it is too dry, the plant will have poor growth performance and easily wither. After the soil becomes dry, it needs to be watered sufficiently, but there should be no accumulation of water. 4. Disease prevention and controlMarigold is easily attacked by stem blight. If it is not treated in time, the plant will easily die. When the disease occurs, medication should be taken as soon as possible. Drugs such as benomyl and thiophanate-methyl can be used, and they must be used consistently. |
