Start seeds the plastic-free way with the Bloom & Gray 28 Soil Blocker — a durable, UK-made tool designed to help gardeners and growers raise strong, healthy seedlings with excellent root systems.
This soil blocker compresses your seed-starting mix into 28 uniform soil blocks, each measuring 54 × 54 × 54 mm. The generous block size holds plenty of compost, allowing blocks to stay moist for longer — a huge advantage during busy sowing periods when watering time is limited.
Ideal for larger vegetable and flower seeds such as sunflowers, cosmos, zinnias, and squashes, the 28 Soil Blocker makes efficient work of sowing sessions. In just a few minutes, you can produce 28 perfectly formed blocks ready for seeding, making it a favourite for market gardeners, allotment growers, and flower farmers alike.
Soil blocking promotes air pruning, a natural process where roots stop growing when they reach the edge of the block and branch out instead. This creates dense, fibrous root systems and sturdy, transplant-ready seedlings — eliminating pot-bound plants and root spirals common with plastic cell trays.
For a low-waste seed-starting setup, pair your soil blocks with strong, reusable shallow trays that can be used season after season.
Each Bloom & Gray Soil Blocker is made in the UK from corrosion-resistant stainless steel, built to withstand years of use. Replaceable silicone dibbles create a neat planting indent in every block, ensuring fast, consistent sowing.
Looking for a smaller option? The Compact 9 Soil Blocker makes 9 blocks at a time.
Need smaller cells? The 112 Soil Blocker and Compact 36 Soil Blocker are ideal for small to medium-sized seeds.
