Compact 9 Soil Blocker (Larger Blocks)

Start your seedlings the plastic-free way with the Bloom & Gray Compact 9 Soil Blocker — a beautifully simple, UK-made tool designed for gardeners, flower farmers, and allotment growers who want strong, healthy plants from day one.

This compact soil blocker compresses your seed-starting mix into 9 perfectly formed soil blocks, each measuring 54 × 54 × 54 mm. The generous block size holds plenty of compost, helping blocks stay moist for longer — ideal during busy sowing periods when watering can slip down the list.

Designed especially for larger, fast-growing seeds such as squash, zinnias, sunflowers, and cosmos, the Compact 9 makes seed starting quick andsatisfying. In just a few minutes, you’ll have 9 uniform blocks ready for seeding.

Soil blocking encourages air pruning, meaning roots stop growing when they reach the edge of the block and naturally branch out instead. The result is dense, fibrous root systems and sturdy, transplant-ready seedlings — without the root spirals and pot-bound stress caused by plastic cell trays.

For a low-waste seed-starting setup, pair your soil blocks with reusable shallow trays that can be used season after season.

Each Bloom & Gray Soil Blocker is made in the UK from stainless steel, finished with a durable polyester powder coating for longevity and a pop of colour. Replaceable silicone dibbles press a neat indent into each block, making sowing fast and consistent.

Need to scale up? This size is also available as a 28-block soil blocker.
