There are many reasons why iris flowers do not bloom during the flowering season. There are several reasons. If it is caused by lack of sunlight, it should be given sufficient light and maintain 6-8 hours of sunlight every day before flowering. If it is caused by unsuitable soil, you can replace it with suitable soil quality and provide fertile soil with good permeability and excellent drainage. If it is caused by improper fertilization, phosphorus and potassium fertilizers should be applied before the flowering period and the application of nitrogen fertilizers should be reduced. If it is caused by a disease, the diseased branches and leaves should be cut off and treated by spraying.

1. Supplementing sunlight

Reason: Irises must have good sunlight to bloom. If there is a lack of light, photosynthesis will be difficult to synthesize nutrients, and naturally they will not be able to supply them to bloom. This is a common reason why iris does not bloom, and this factor is critical.

Solution: In order to promote the beautiful flowers of iris, it should be given sufficient light and maintain 6-8 hours of sunshine every day before blooming, but no strong light.

2. Replace the soil

< /p>

Reason: Irises like to grow in alkaline soil. If the soil provided is unsuitable or acidic soil is used, these soils are not suitable for growth and will directly affect flowering.

Solution: It likes fertile soil with good permeability and excellent drainage. If the soil itself does not meet the growth needs, you can replace it with suitable soil quality.

3. Reasonable fertilization

< /p>

Reason: Improper fertilization and lack of fertilizer will cause the plants to lack nutrients. Too much nitrogen fertilizer will also cause iris flowers to have difficulty blooming.

Solution: When it grows and blooms, you should pay attention to reasonable fertilization. Apply phosphorus and potassium fertilizer before the flowering period and reduce the application of nitrogen fertilizer.

4. Prevention and treatment of diseases

< /p>

Cause: Infection with diseases can also affect normal flowering and hinder plant growth.

Solution: Pay attention to prevention at ordinary times, prune diseased branches and leaves promptly after the onset, and spray pesticides for treatment.
