Wisteria bonsai, with its graceful posture and evergreen leaves, has become a favorite of many gardening enthusiasts. To cultivate a healthy wisteria bonsai, the choice of soil is crucial. What kind of soil is best for wisteria bonsai? This article will reveal this secret.
Wisteria Bonsai Basic Soil RequirementsThe requirements for soil in wisteria bonsai are not high, but there are some considerations. Wisteria bonsai thrives in soil that is well-ventilated, well-drained, fertile, and slightly acidic.
Common Wisteria Bonsai Soil Recipes1. River sand mixed with decomposed leaf soil: River sand can increase the soil's air permeability and drainage, while decomposed leaf soil provides abundant organic matter and nutrients. The ratio of this mixed soil is usually 1:1.
2. Decomposed leaf soil mixed with garden soil: Garden soil contains certain nutrients, while decomposed leaf soil helps with the soil's water retention and air permeability. The ratio of this mixed soil can be 2:1.
3. Decomposed leaf soil mixed with coarse sand: The ratio of this mixed soil is usually 1:1, suitable for wisteria bonsai that prefer a slightly dry environment.
Wisteria Bonsai Soil pH ValueWisteria bonsai thrives in soil with a pH value of 6.5-7.5. Soil that is too acidic or alkaline is not conducive to the growth of wisteria.
How to Test Soil's Air Permeability and Drainage1. Observe the color of the soil: Healthy soil should be dark brown or black, indicating the presence of rich organic matter.
2. Squeeze the soil: Healthy soil should be able to be easily squeezed into a ball but should not be too compact, as this would affect the soil's air permeability and drainage.
3. Watering test: Pour water into the soil and observe its infiltration rate. If the water can rapidly infiltrate, the soil has good drainage.
