Sustainability for flower farmers

Nov 11, 2025

How do we define ‘sustainable flowers’? This is an essential question to ask, for growers, wholesale hubs, and florists alike.

In this video, Theresa Schumilas of Garden Party Flower Farms discusses how to define sustainable flowers in an authentic way, arguing that sustainability must start with the soil. She also walks you through an audit of sustainable practices on her own farm, highlighting successes and areas for improvement. 

Nobody can give you a ‘yes’ or ‘no’ answer on sustainability. I think a better question to ask a farmer is ‘Tell me about your soil building practices.’
