Right or wrong a florist is not considered the most manliest of professions for a guy. I think I know how to change that. Simply change the name of the job.
When it comes to carpenters - you have framers and guys who do finish work. Both are carpenters and both jobs are considered equally manly. Likewise if you think of it trees are just giant plants and cutting down trees could be considered similar to what framing houses is to carpentry.
Having said all that - here's my idea; change the name of the job from florist to flowerjack.
Having said that - here's the Lumberjack Song.
