Career as a Gardener UK?

I have ADHD and have spent quite a lot of time career hopping. I would really like to try gardening though, specifically to work for myself in garden design.

What would be the best route though? What qualifications would I need and should I (at age 21) go back into education to get them or spend some years working, save up, and then pay for them?
