Soil blocking turns a prepared seed-starting mix into planting blocks that sit directly in a tray. The routine works well when the mix is fine, the tray is flat, and water reaches the blocks gently from below.

Start with the block size
The Ladbrooke Mini 4 presses four 2 inch blocks. That size gives seeds, cuttings, and young starts a defined cube of mix for early growth.
The BlumWay 8 Cell Soil Blocker presses eight 2 inch blocks in one pass. It fits a bench setup where the mixing tub, tray, labels, and cleanup towel are all within reach.
Use micro blocks for tiny seed rounds
The Ladbrooke Micro 20 creates twenty 3/4 inch blocks for compact starter trays. These tiny blocks ask for a screened, moist blend and a careful watering habit.
Ladbrooke Cubic Inserts shape square pockets in compatible 2 inch blocks. Those pockets give Micro 20 starts a clean landing place during the next growth step.
Prepare the mix before pressing
Soil-blocking mix needs a moist, cohesive feel. Jiffy G316 Seed Starting Mix and Burpee Organic Coir Seed Starting Mix are useful reference points for tray-friendly texture.
The Wenses Soil Sifter helps screen coarse bits from compost or reused mix. The soil texture guide covers coir, perlite, vermiculite, tubs, scoops, and note taking for mixing days.
Give fresh blocks a tray with water control
RooTrimmer 1020 solid-bottom trays give soil blocks a contained base. The tray holds the blocks flat, gathers loose mix, and keeps water visible during bottom watering.
BeGrit 1020 mesh trays add an open layer for soil blocks after watering. Handy Pantry 1020 garden trays add a solid base stack for shallow water, wet tray pieces, and microgreen rounds.
The Felt Store Kapmat can add a cut-to-fit moisture layer under pots or tray pieces. The Bootstrap Farmer 1020 tray gives tray work a sturdy support option.
The 2Pack watering mat adds broad capillary material for tray zones. Gardener’s Supply Company capillary mat adds a long roll for shelf rows. The 50ft wick rope and Augshy 70ft wick cord give small reservoir routes a cut cord supply.
The wick cord and capillary mat guide brings cord, mat, replacement water mat, and watering stake choices into one water-control routine.
Keep watering gentle
Fresh blocks hold together with calm watering. Add shallow water to the tray, let the blocks take up moisture, and empty the tray after the surface feels settled.
The Fiskars Plant Mister gives surface moisture a light touch after sowing. The seed-starting watering guide covers misters, capillary mats, dome venting, airflow, and quick shelf readings.
Reset the tools after the tray is planted
Rinse soil blockers after use, dry the frames, and store seed pins or cubic inserts in a small labeled container. Let solid trays dry before stacking.
The tray reset guide gathers labels, misters, brushes, and dry storage into one seed-shelf routine.
