The editor provides netizens with answers on how to care for iris flowers and shares some small experiences in planting and managing iris plants. Next, let's introduce them.
Caring for iris flowers is very simple. You just need to choose the right substrate, ensure suitable temperature and lighting, water and fertilize appropriately, and do a good job of pest control and weeding. It is easy to keep iris flowers healthy. Below, we will explain in detail the methods for growing iris flowers.
1. Substrate Selection
Iris flowers do not have high soil requirements, but it is best to choose soil with good drainage. Generally, peat, coarse sand, and vermiculite can be mixed in a ratio of 4:3:3.
2. Temperature and Lighting
The optimal growing temperature for iris flowers is 16-18°C. Too high or too low temperatures are not conducive to their growth. It is best to grow them in a greenhouse when there are significant temperature fluctuations. Iris flowers enjoy sunlight and should be exposed to light frequently. In the summer, when sunlight is too strong, they can be appropriately shaded.
3. Water and Fertilizer Management
Iris flowers like moisture but are afraid of waterlogging. Watering should be based on the soil's dryness or wetness, keeping the soil slightly moist but not dry, and avoiding waterlogging that can cause root rot. Iris flowers do not need too much fertilizer. It is sufficient to apply a compound flower fertilizer or diluted thin cake fertilizer water before flowering in the spring growing season. After the flowers fade, it is best to apply another thin liquid fertilizer.
4. Pest Control and Weeding
Iris flowers are prone to pests and diseases such as nematodes and gray mold. When pests occur, a diluted phosphorus imidacloprid solution can be used for pest control. When diseases occur, the diseased leaves should be cut off, and the plant can be transplanted in severe cases. Also, when there are too many weeds, a corresponding herbicide can be sprayed, but note not to exceed two applications per year.
