What soil is best for growing a Radermachera sinica (China doll)? Detailed soil mixing guide

1. Requirements for the growing medium

There is a saying that every plant has its own growing medium. Although this saying is a slight exaggeration, it still holds some truth. This is because every plant has its own habits and characteristics, which determine what kind of soil is most suitable for growing it.

1. Air permeability

During its growth and development, its underground tissues, like its above-ground tissues, also need to breathe, which determines that it is not suited to overly compact growing media, while relatively loose, air-permeable growing media are more suitable for growing it.

2. Good drainage

It is very afraid of waterlogging. Once water accumulates in the growing medium, it can no longer continue to grow normally. There are two reasons for this: first, the accumulated water may rot its roots; second, its roots will find it difficult to breathe in water. Once the function of the roots becomes abnormal, it cannot normally absorb nutrients from the growing medium, and thus cannot grow normally.

3. Rich and thick

A rich, thick growing medium contains abundant nutrients. After it absorbs these nutrients, it can grow quickly. In addition, if the soil also contains a small amount of humus, its growth will be even more vigorous.

2. Preparation of the growing medium

Based on the above requirements for the growing medium, we provide a common growing medium preparation method:

Garden soil : leaf mold : decomposed organic fertilizer : river sand = 5:3:1:1

This growing medium has extremely strong fertility and can provide it with enough nutrients to support its growth and development.

In addition, during preparation, the pH can be adjusted to 4.5-6.5, which can make it grow better.
