Since we're aiming for financial recovery in the garden, I just love volunteers -- the plants that grow from compost or simple self-seeding. We've got two plants that are probably in the squash/melon family that sprouted about a month ago and are growing like Jack's beanstalk. We also have a couple that I'm pretty sure are butternut squash seedlings, since they sprouted in the area where we composted last fall. Whatever they are, we have plenty of room, and it's like getting free (and often care-free) plants.
We also have another kind of volunteer -- Paul -- who tilled the two extra-weedy beds that we'd almost given up on. Okay, so he was volunteered by someone else, but he was great about it and generous with his time and energy and tiller.
Despite all the planning and the investing and the science, really, it's the volunteers that make a difference in the recovery garden.
