Soil Block Maker, Large - Makes Four 2" Blocks

Soil blocking is a simple and easy way to start seeds in a home setting.  The Large Blocker is perfect for planting those larger seeds like squash and sunflowers. 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. * This blocker is transitioning to a black finish. During this change, you may receive either a silver or black soil blocker. We appreciate your understanding and apologize for any inconvenience.

Here is what customers are saying about how soil blocking has changed their seed starting experience.

Customer photo review of Soil Block Maker Large 4 Cells

These soil blocks are wonderful. I haven’t transplanted to the garden yet but I’m imagining that the seedlings will take to it much better.

The block seed starts are far superior to regular container starts.

Soil Block Maker, Large

I love working with Gardeners Workshop. The tools are great. Seeds are nicely packaged. As a new flower grower I wish the seed packets had a photo on them. Then I know what colors I am planting where. The seeds are great and germinate well.

First time making soil blocks. I really enjoyed the process and the seedlings are looking great.

Soil Block Maker Large 4 Cells

Couldn't believe how quickly the seeds germinated and the roots began growing down to the trays. I started a few zinnias late in May as I am in Michigan and they already have buds on them.

10 out of 10 recommend this soil blocker if you're interested in soil blocking! It's so fun to use, easy to squeeze, and easy to clean. I did forget to clean it overnight once and I didn't rust, so that's a bonus!

Love my new block makers! The instructions were easy to follow. I made several blocks for my Zinnas and they grew fast and healthy! This is a game changer for me. Love the simplicity and the fact that I am using way less plastic. Will definitely recommend to all my friends!
