The second step is to assess your space. If you have a small space, then you have to think outside of the box in terms of how to make the more efficient use of your space. Not only can you set plants on a sunny patio, but you can also use vertical space as well. Many urban gardens use trellises or garden netting to support vining plants like tomatoes, berries, squash and beans. Moreover, you can also use topsy turvys or fashion one from a 5 gallon bucket. Urban gardeners are also screw in rain gutters to create small, uniformed beds. This is a great way of growing lettuce, spinach or strawberries!
