Begonia Soil Requirements

Begonias need to be planted in a well-draining potting mix with an acidic pH level between 5.2 to 6.0 (5.5 being ideal)
Begonia Soil pH
Soil pH is important for various reasons, but mostly because soil acidity affects the availability of several nutrients to plants. While begonias may grow well in a wide pH range, they prefer soils with an acidic pH level between 5.2 – 6.0
Begonia Soil Type
Begonia plants prefer light sandy soil with excellent drainage. The best type of potting mix for a begonia is a well-draining mixture of peat moss and sand or perlite.
Begonia Soil Mold Problems
There are many ways to handle begonia soil mold problems including taking preventative measures, properly maintaining your plants, and using fungicides.
