If the soil pH is unsuitable, you can use regulators such as ferrous sulfate to adjust it.

Pests and diseases: Carefully check the leaves, branches and roots of the pine and cypress bonsai for signs of pests and diseases. If pests or diseases are found, take corresponding control measures promptly. You can spray insecticides and fungicides, or remove the pests and diseases by hand.
