Cultivating irises 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's easy to keep irises healthy. Below, we will elaborate on the cultivation methods of irises.
1. Substrate Selection
Iris doesn't have high requirements for soil, but it's best to choose well-draining soil. Generally, peat, coarse sand, and vermiculite can be mixed in a ratio of 4:3:3.
2. Temperature, Lighting
The optimal growing temperature for irises is 16-18°C. Too high or too low temperatures are not conducive to their growth. It's best to cultivate them in a greenhouse when there are significant temperature fluctuations. Irises enjoy light and should be exposed to it frequently. In the summer, when the sun is too strong, some shading is appropriate.
3. Water and Fertilizer Management
Iris prefers moisture but is afraid of waterlogging. Watering should be based on the dryness of the soil, keeping it slightly moist but not dry, and avoiding waterlogging that could rot the roots. Iris does not need a lot of fertilizer. It is sufficient to apply a compound flower fertilizer or diluted thin cake fertilizer water before flowering in the spring. After the flowers fade, another application of thin liquid fertilizer is recommended.
4. Pest Control and Weeding
Iris is prone to pests and diseases such as nematodes and grey mold. When pests appear, a diluted solution of phosphorus and imidacloprid 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 times a year for weeding.
