Money doesn't grow on trees, but you'll need a bit of cash to plant one.

Between paying for sprinkler systems, plants or landscaping services, gardening and landscaping can be an expensive hobby (or chore.) And whether you're just trying to make your grass greener than the other side's or you're trying to out-do the local farmer's market, Americans spend a decent portion of their time tending to gardening and landscaping: the average American spends 14 hours tending to landscaping and gardening tasks in any given week, about 2 hours each day.
