If you live somewhere that doesn’t have any soil but just a patio you can do container gardening. Plant your flowers and plants in containers. These don’t have to be expensive decorative plant pots if you can’t afford. Cheap empty buckets such as those that had paint in once washed out can be used to grow food in. But if you want your garden to look decorative a low maintenance then have some attractive plant pots with some flowers, herbs and plants that grow back every year such as strawberries and mint.
