A balcony garden.
With the weather getting hotter I looked at my balcony to see what I want to do with it this year. I browsed the internet and find a whole site about Square Foot Gardening. Though I have limited space, I think I can manage a few boxes about 30cm x 30cm (1'x1') in a row. Not technically what the site mentions, but close enough.
I have a bunch of strawberry-plants that could go in, and I want more fresh herbs (I hate buying them in the store). Mmm project!
