Spring means it's time for gardeners to think about seedlings, those little baby plants all ready to get plunked into the ground. And a hands-on technique for growing them, called "soil blocking," is capturing the attention of serious gardeners. Among them is Christopher Hallett.
He's a farm manager at Growing Hope Urban Farm , a community garden center in Ypsilanti, Mich. Hallett started soil blocking a few years ago, and taught a class last week to six aspiring soil blockers in one of the facility's outdoor greenhouses. "Take your fingers and go, boom boom boom boom," he says, demonstrating how to pack a mixture of peat moss, dirt, lime, perlite and other components into galvanized metal boxes equipped with a lever.
The tool pushes out the packed soil blocks into neat rows, like an old-fashioned ice cube tray. Many in the class were drawn to soil blocking because it's an environmentally friendly method to prep seedlings. "You don't have to use as much plastic," Donna Kolojeskie says.
A retiree, she's gardened her whole life. ("And I'm getting seedier by the day!" she jokes.) Kolojeskie says she's enjoyed learning a new skill that can cut down on her purchases of disposable containers of seedlings at big box stores.
Even peat pots, Hallett points out, are not a sustainable resource. "Those little fabric things around the peat pots are even worse," he adds. "You can't get rid of 'em.
They say 'biodegradable' but they're woven plastic." Soil blocking tools, he says, are econom.
