1. Maintenance methods1. Temperature: The most suitable temperature is around 18 degrees. It will not be good if it is too high or too low. Generally speaking, at 13 degrees or lower, its growing period will be prolonged and the flowers will easily wither. Too high a temperature can also have adverse effects. 2. Light: Irises love light. It can tolerate partial shade, but a too dark environment will have a negative effect on its growth and flowering. Therefore, in order to meet its requirements, try to let it receive more exposure when the sunlight is not so strong. Under strong sunlight, shade is needed. 3. Watering: Iris likes moisture, but it is very afraid of waterlogging. Adequate water can not only meet its own needs, but also reduce the concentration of fertilizer and avoid fertilizer damage. Another important task is to have a good drainage system to avoid excessive water accumulation. 4. Fertilization: Generally speaking, it is not advisable to have base fertilizer in the soil, otherwise the salinity will be very high. Then apply fertilizer. Be careful not to use fertilizers containing fluoride easily. 2. Breeding techniques1. Reproduction: It can be propagated by bulbs. If the bulbs cannot be planted immediately, they need to be stored in a low temperature environment, generally around two degrees, and maintain appropriate humidity. Wait until the right time to plant it. After planting, temperature and humidity are also two very important aspects. 2. Weeding: If weeds appear after the plants are planted, they must be cleaned up. Herbicides can only be used if the bulbs are buried deep enough, but not if the bulbs are buried very shallowly. In addition, you need to pay attention to the amount of herbicides used each year. It is best not to exceed twice. 3. Problem diagnosis and treatment1. Disease: "Bull rot" is a relatively common disease that is spread by a kind of spore. You can spray medicine and reduce the humidity of the air. There is also "gray mold", which can cause growth stunting and serious damage to the leaves. Use medication in time and avoid strong light. 2. Pests: There are "nematodes", which are not only harmful themselves, but also easily spread some other diseases. Pesticides can be used and the soil should be disinfected. IV. Other issues1. Flower language: The flower language of blue-purple iris includes "missing", "good news", etc. 2. Toxicity: It is poisonous, the whole plant is poisonous, but it is very mild. |
