It’s easy! Simply use containers on hand, like leftovers from all the trees you planted last year, or make a raised bed garden with left-over wood from when you built your new fence (or your neighbor’s leftovers), reclaimed or salvaged wood works great too.
Some things to keep in mind when you build your raised bed garden:
3′ wide is plenty wide enough, you need a comfortable reach
6′ long is also long enough to ensure the same comfortable reach
1′ high is okay, but if you do 2′ you won’t have to bend down as far to reach your plants
If you build close to your house you will use the heat from your house to help insulate your garden
