Step 1: Choose and Prepare Location for Garden Bed

1.1. A good option for raised garden beds is building them on the south side of the structure – there will be enough sun and place on walls if you decide to fasten a few additional special hanging garden beds. Another choice is to place it on the north side of your backyard; make sure the chosen area is not too shady.

Consider these factors:

Sun exposure
Easiness to reach
Water proximity
Drainage
Wind directions.
