Sowing in trays is perfectly suited to growing plants in a sheltered place.
Thanks to small holes drilled at the bottom of the tray, drainage can be optimized and is very effective.
A great many plants, vegetables and flowers can be sown in this manner. Avoid this technique for taproot-type plants (like carrots) and plants that should be started directly in the growing bed.
Sowing in trays, broad pans & shallow crates
- Place clay pebbles at the bottom of the tray (in a layer about ½ to 1 inch (1 to 2 cm) thick) to ensure drainage.
- Fill the broad pan or tray up to ⅔ full with seedling soil mix or substrate prepared from peat or soil mix (one part) and river sand (one part). Don’t add any fertilizer.
- Flatten thereafter with a trowel or a slab of wood, and add soil mix until the tray is ¾ full.
- Press down again.
- Sprinkle seeds evenly throughout the tray.
- Press down lightly with a wooden board.
