From Master Gardener programs to formal degrees, what education has helped you grow (pun intended) in your career?
The single credential that moved the needle for me was a state pesticide applicator license after an IPM short course — it ‘paid for itself’ faster than a tray of microgreens. Are you leaning production or landscape maintenance? Either way, your local extension has prep classes and practice tests to get you started: https://extension.org/extension-map/.
