Guerilla Gardening turns neglected land into gardens.

You may not have a yard. You may not even have a balcony. But, with the right attitude and some seed balls, the world is your garden.
Guerilla gardening usually describes the act of turning desolate bits of land… abandoned lots, road medians, etc… into vibrant community gardens full of blooms.
You can go one step beyond and turn neglected land into a pantry.
Taking seeds that will grow in your part of the country and planting them… or even just tossing seedballs… into appropriate areas has the potential to provide you with extra food supplies on the down low.
Ideally, you want to keep these less than obvious. Growing pumpkins at a street corner may not work well. Growing potatoes in a hydro field, or a back alley, may work better. Think small or inconspicuous. And, of course, in the case of potatoes, you can also plant the potato itself and wait for nature to work its magic.
To create a seed ball, you mix dry potter’s clay with homemade compost and seeds, roll them into small balls, then let them dry. Toss the seed balls wherever you want the plants to grow and hope for the best.
This is an excellent conversation about the ins and outs of making your own seed balls.

Spring is coming quickly, so it’s time to move quickly.
We’re also running out of time to buy seeds. Make sure you buy organic whenever possible. Heirloom is even better. You can even save seeds from the vegetables you eat or, in the case of the likes of zucchini, toss leftover veggies that you might otherwise compost.
P.S. In the comments on the video above, Ben Riley suggested you “use Premium cat litter (That includes bentonite) to save money if you don’t have clay on hand.”
