Why growers reach for a Swift Blocker

A soil-blocked seedling at transplant time — dense roots, air-pruned at the edges, no circling
A soil-blocked seedling at transplant time — dense roots, air-pruned at the edges, no circling

Roots that move without the shock

When a root hits the open edge of a block, air stops it — so seedlings build a dense, fibrous rootball instead of circling. They transplant like they barely noticed the move — most starts ready to plant out in about four weeks.

Seed before you eject

Sow the whole tray, dust with vermiculite, then press the blocks out. Faster than dip-and-press blockers — and impossible with them.

Kind to your hands

The lift-to-eject action skips the squeeze — no strain on the hand or wrist. Growers with carpal tunnel or arthritis tell us it's the difference that lets them keep sowing.

Made once, in Michigan

Stainless steel, handmade in southeast Michigan. A buy-it-once tool built to outlast a shelf of plastic trays.

OBSESSED with the improvements made on this version! Fills up a 1020 tray perfectly, and I love that the dibbles are stamped instead of rubber. The steel also feels sturdier compared to older units. Just remember to use sifted soil mix, or soil mixes made specifically for soil blocking so you don't clog up/bend the cells

Terrible. The product arrived damaged. I reached out to get another one. I did get a quick response, but they never re-sent the product or a return label.

Absolutely a game changer. I can't wait to stop using winstrip trays. The swift blocker saves us time forming blocks and I am sure it will save us time transplanting those blocks.

Top quality and craftsmanship- just what I needed for smaller seeds that will go straight to the garden w/out potting up. Planting my prize long-day onions in them- 1 seed per 128 cell. Looking forward to compare the results to bulk-onion sowing I usually do. Thank you!

I love this tool! It allows us to quickly and easily make a full tray of soil blocks all at the same time using trays that we already have. It's obvious that the Swift Blocker was thoughtfully created, and I'm so grateful. This was our first purchase, but I doubt it will be our last. Five enthusiastic stars from WildAugust Flowers!

This soil blocker is exactly what we needed! After working with the old stand-up style blocker for the past 7 years, we are delighted to have this much more ergonomic block maker. The blocks come out perfectly and fill the 10x20 trays nicely so less space is wasted in our greenhouse. The coated metal is awesome to keep things clean!
