I grow fresh food organically from home.
Right now, I'm just starting out, so I'm doing a lot of experimenting. For most of the day, I do a ton of research on new ways to grow my vegetables on sites like Pinterest.

You can start pursuing gardening at any time and any age. I literally started gardening using just a plastic tub and some lettuce that I'd bought from the store, so you don't need too many resources to get started!
