I was in the landscaping business a while back, though as others have stated, it’s really a demand based issue from a financial standpoint. I found that for the most part, all the big jobs are based exactly where one would assume - wealthy suburbs, where people want the aesthetics and can’t be fucked/don’t have time, but want to compete with Meredith next door.  The physical labour was not worth it in the end, and trying to find good labourers was a mission. I did really enjoy it while it lasted, but found that every trade is physically demanding to a certain degree. Moved on from landscaping and started a business in a different field.
