Soil Block Maker Trio, All 3 Blocker Sizes
Soil blocking is a simple and easy way to start seeds in a home setting. We use the Small Blocker for most of our flower, vegetable, and herb seeds. The Medium Blocker is perfect for planting those larger seeds like peppers, eggplant, tomatoes, pot marigolds, and cuttings. The Large Blocker is perfect for planting those larger seeds like squash and sunflowers and can be equipped with cube inserts that allow you to move a seedling growing in a small soil block into the larger soil block to continue its growth. There are no pots or trays to store or purchase each year. We use trays without drainage holes so it can be done anywhere indoors. We find that the seedlings are healthier, grow quicker, and in general hit the ground running and suffer no transplant shock.
Here is what customers are saying about how soil blocking has changed their seed starting experience.
