Basic requirements for iris potting soil

Iris loves light, is cold-resistant and drought-resistant, and is not picky about soil. However, in order to promote its growth better, the breathability and drainage of the soil are particularly important. The ideal iris potting soil should have the following characteristics:

1. Good breathability: beneficial for root respiration and plant growth.

2. Good drainage: prevent water accumulation and avoid root rot.

3. Rich in nutrients: providing the nutrients needed for iris growth.

Proportion of iris potting soil

According to the above requirements, here is a common iris soil mixing scheme:

1. Decomposed leaf soil: 40%

Decomposed leaf soil is a type of soil with high organic matter content, rich in nutrients needed by plants, which is beneficial for iris growth.

2. River sand: 20%

River sand has good breathability and drainage, ensuring the normal respiration of iris roots.

3. Perlite: 20%

Perlite is a lightweight material with good breathability and drainage while also enhancing soil fertility.

4. Peat: 20%

Peat is an acidic soil, which is beneficial for iris growth.

Precautions

1. pH value of iris soil: The pH value of iris soil should be between 5.5 and 6.5. Excessive acidity or alkalinity will affect the growth of iris.

2. Avoid using chemical fertilizers: Iris soil is already rich in nutrients, and excessive chemical fertilizers can burn the roots.

3. Regularly replace iris soil: Every 2-3 years, the iris soil should be replaced to ensure soil fertility and breathability.

The soil proportion for iris potting is crucial for its growth. Through the above introduction, it is believed that you have a comprehensive understanding of the proportion of iris soil. Reasonably mixing the soil during the care of iris will add a beautiful landscape to your garden.
