How to grow blue lily

1. Maintenance methods

1. Temperature: It has a strong adaptability to temperature and can grow under relatively cold conditions. This can be seen from the fact that its distribution area is mainly in the north. Although it is relatively cold-resistant, its heat resistance is not very good, so some measures can be taken to cool it down in summer.

2. Light: Indigofera is a light-loving plant. As long as the sunlight is not too strong, full sun is generally available. Appropriate shade is only needed in the summer when the sunlight is relatively strong, but it should not be placed in complete darkness. When it blooms, pay special attention to providing sufficient light.

3. Watering: Indigofera does not require much water because it is a very drought-resistant plant. During the growing and flowering periods, the soil can be kept semi-moist, but no water can accumulate. When it is hit by rain, the excess water needs to be drained in time.

4. Fertilization: Due to its strong adaptability, it does not require much fertilizer. In addition to base fertilizer, top dressing can be applied once or twice a month.

2. Breeding techniques

1. Reproduction: It can be propagated by division. April is more suitable. The first step is to choose a strong mother plant. Generally speaking, it is more appropriate to divide each mother plant into three to five parts. The specific number can be determined according to the volume. Plant them separately, with a row spacing of about 15 cm and a plant spacing of about 15 cm. After planting, compact the soil and then water it thoroughly.

2. Pruning and weeding: These two steps are also very important. Pruning can be done in spring, cutting off some dense and yellowing branches and leaves. It can also be slightly trimmed after flowering. Another thing is that when there are many weeds, they need to be cleaned up in time.

3. Problem diagnosis and treatment

1. Diseases: There are relatively few diseases. Occasionally there may be "leaf blight", which is more likely to occur in summer. Just spray the medicine in time.

2. Pests: Relatively speaking, there are more pests than diseases. During the seedling stage, the damage caused by mole crickets is relatively serious and can be controlled by using chlorpyrifos. From July to August, there are more aphids, and omethoate can be used.
