Description
Silica sand is an excellent medium for cold, moist stratification — a simple and effective process used to overcome seed dormancy and encourage germination.
To use, combine moistened silica sand with your seeds in a sealed container or plastic bag. Place in the refrigerator for the recommended duration (check your seed packet for timing), and monitor regularly for moisture and early germination.
Silica sand is ideal for this process thanks to its light colour, which makes it easy to see and retrieve seeds against the pale background. It also provides excellent drainage and aeration, reducing the risk of mould and rot during stratification.
