Creating a begonia potting soil recipe at home can be both economical and tailored to your plant’s needs.

Where to Buy Begonia Potting Soil
Begonia potting soil can be purchased at any major garden center, online retailers, or specialty plant shops.

The ideal Rex Begonia soil mix should focus on providing good drainage with a rich organic base.
Combine two parts peat moss, one part perlite, and one part pine bark to create an airy texture suitable for Rex Begonias. Consider adding a slow-release fertilizer to support their intensive foliage growth patterns. Avoid dense or moisture-heavy mixes that could suffocate their root systems.

Begonia Potting Soil Ratio
The standard begonia potting soil ratio should be light and well-balanced, typically leaning towards more organic matter.
