Nominate a Young Grower Today!

Congrats to the 2025 GrowerTalks/Ball Horticultural Company Young Grower Award winner:
Isabela Chamorro from Mahoney’s Garden Center, Woburn, Massachusetts!

Do you know of an excellent, hard-working professional under the age of 35? You should nominate them for the 2026 GrowerTalks/Ball Horticultural Company Young Grower Award! For the last 21 years, we’ve recognized young horticulturists for standing out from the crowd in this tough business, who—for whatever noble reasons—have chosen to have a career in this industry.

After three finalists are chosen, each is asked to write guest editorials for the June issue of GrowerTalks, gets a free trip to Cultivate’26 and, while they’re in Columbus, attend a special dinner with Anna Ball and other industry luminaries. The winner is announced at the Unplugged event during Cultivate’26, will be the subject of our September issue cover story and serve as one of our judges for next year’s award.

An extra special thanks goes to Ball Horticultural Company, BASF and AmericanHort for sponsoring this year’s award!
