Gardening doesn’t have to be complicated, but there are a few things that you have to have to make it work. You have to have plants or seeds, a place for them to grow, and also water and sunlight. You can use municipal water for your garden, but the downside of that is it doesn’t come free.
However, if you are lucky enough to live in a location where it rains, you can offset at least part of that cost by using rainwater in your garden instead. In many areas, with some pre-planning you can even use rainwater for all your landscaping water needs!
