You might have made a couple of bucks mowing lawns as a kid. For adults, taking care of greenery can be much more lucrative.
Common tasks for those in the field include mowing, planting, raking and edging. If you're cooped up in an office for most of your working life, spending some time outside while banking some money can be the perfect antidote.
You won't need any special training to pick up a leaf blower or a shovel, and you'll have the satisfaction of seeing the results of your work over time.
The pay averages $15.70 an hour, and you can make more or less depending on the location. There's a lot of potential for job seekers, with 6 percent job growth expected by 2024, according to the Bureau of Labor Statistics.
