What type of soil is better for growing succulents
Among many potted plants, succulents are highly favored for their unique shapes and easy maintenance. The key to growing healthy and plump succulents lies in mastering the scientific soil mixing method. This article will provide a detailed analysis of soil mixing solutions for succulents at different growth stages and reveal practical techniques for making low-cost granular soil.
Golden rules for succulent soil mixing
Seedling stage soil mixing solution
Leaf cuttings and young plants (1-2 years old) are recommended to use a combination of 50% peat soil and 50% mixed granules. High-quality peat soil can provide sufficient nutrients, and when combined with a fine granular matrix of 3-5mm, it can ensure water retention without waterlogging. It is recommended to use a combination of red jade soil, vermiculite, and rice husk charcoal to promote the development of capillary roots.
Growth stage soil mixing ratio
Mature plants over 3 years old need to be adjusted to 30% peat soil and 70% granular soil. At this stage, a medium granular matrix of 5-8mm should be selected, and a mixture of volcanic rock and Songmu stone in a 1:1 ratio works best. Adding 10% pine bark chips can enhance breathability and prevent root rot in summer.
Secret recipe for controlling the growth of old stakes
Wooden stakes over 5 years old are recommended to use a formula of 20% peat soil and 80% coarse granules. Using a large granular mixture of 8-12mm, a combination of diatomite, green zeolite, and Kiryu sand is recommended. Green zeolite contains trace elements that can delay leaf aging, and combining it with 10% coconut shell fragments can create a natural controlling environment.

Obtaining granular materials
Construction waste can be processed as a high-quality alternative: red brick fragments need to be sieved to retain 3-12mm granules, and coal slag should be soaked repeatedly for 7 days to remove alkalinity. It is recommended to combine 30% river sand and 20% broken charcoal, which can significantly improve soil breathability.
Matrix disinfection treatment
Homemade soil needs to be sterilized at high temperatures: spread the mixed matrix on a baking sheet and bake at 200°C for 30 minutes. After treatment, add 5% carbendazim powder, which can effectively prevent diseases and pests such as root mealybugs. Adding 3% bone meal can supplement calcium and strengthen stem hardness.
Scientific soil mixing is a core part of succulent care, and the matrix ratio needs to be dynamically adjusted at different growth stages. Mastering the technique of making granular soil can not only reduce maintenance costs but also customize a specific formula based on the characteristics of the plant. It is recommended to observe the root condition when repotting every year and optimize the soil structure in a timely manner.
