I do it myself, but mainly because I don't have a ton of money to contract a good landscaper. I am currently posting while applying a hot water bottle to my sore body after several hours of transplanting, edging, weeding and mulching. It is definitely possible to enjoy a beautiful garden and have a professional do the work.
Then you can do the picturesque stuff like cutting flowers LOL inhaling the scent of roses and having garden parties.
Gardening is a good way to get some exercise if you need it, though. But a lot of insane gardeners are probably like me, and tend to overdo it. I have had professionals do things like planting trees and shrubs and installing fencing etc. One thing I really enjoy doing is mowing LOL I do a terrible job, but I love zipping around on the mower.
I got myself an edger for Christmas last year, and used it for the first time. I did an awful job
, and used a LOT of bad language. But that was fun, too. I like garden toys.
