Soil Blockers are used to create free standing blocks of soil into which seeds can be sown one by one. The soil block can then be transplanted into a larger soil block or directly into the garden when the time is right. Soil Blockers do away with seedling trays and plastic pots, so they present an eco-friendly alternative for home gardeners or small scale organic growers. Our soil blockers are the best quality, made in the UK by Ladbrook.
