Ladbrooke Soil Blockers
Made in England by Ladbrooke Ltd. The soil block system allows for easy transplanting and eliminates root spiraling.
A successful recipe for soil block mix (with thanks to Eliot Coleman): Mix 2 10-qt. buckets peat or coir with 1/2 cup of lime and 2 cups of azomite. Add 2 buckets of sand, 2 more buckets of peat, 1 cup of phosphate, 1 cup of greensand, 1 cup of bloodmeal and 1 more cup of azomite. Mix well. Add 1 bucket of compost and 1 bucket of soil and mix again. Add water until the mixture is spongy but not soggy and start making blocks.
