Floral foam has long been a staple in the floral industry, praised for making floral arrangements faster and more convenient. Many florists rely on it for its ease of use, but as awareness grows about the environmental and health impacts of floral foam, it's becoming clear that we need to rethink its place in our industry.
Floral foam is a type of single-use plastic, and its environmental footprint is staggering. Each block of foam contains as much plastic as 10 plastic shopping bags.
After it's used, floral foam can take thousands of years to break down, and as it decomposes, it releases microplastics into the environment. These tiny particles wash into our waterways and have been found in fish, our food, and even in our own bodies. There are numerous studies and articles about the known and unknown potential impacts on nature, animals and human health. A collection of horror stories...
As floral foam breaks apart in flower arrangements, it contaminates the flowers and foliage, making them unsuitable for composting. As a result, both the foam and the flowers end up in landfill, adding to the growing waste crisis.
Floral foam is not just an environmental hazard—it's also toxic. Made from chemicals including phenol and formaldehyde, it poses serious health risks.
Formaldehyde, a known carcinogen, can cause skin irritation and respiratory issues with prolonged exposure. Worse still, these chemicals leach into the environment when the foam is disposed of, contaminating our waterways and harming aquatic life.
To extend the life of cut flowers, floral foam is chemically treated to maintain a pH balance. But this process involves additional chemicals, further impacting the delicate pH balance of ecosystems when the foam is discarded.

The tide is turning, though, and there is hope. In 2020, the Royal Horticultural Society (RHS) made a ground-breaking decision to ban floral foam from all its events. That means no foam is used at prestigious shows like Chelsea Flower Show, a huge step in promoting sustainable floral practices. Now, even institutions like the Church of England are considering following suit—imagine the impact this could have on floral displays in churches across the country!
There are an increasing number of courses and workshops to learn new ways of creating eco-arrangements.
The good news is that there are countless alternatives to floral foam. With a little creativity and ingenuity, florists can craft stunning, eco-friendly arrangements without relying on plastic. After all, flowers were arranged beautifully long before the invention of floral foam in the 1950s. In an upcoming post, I’ll be sharing some of these innovative techniques and ideas.
For me, it’s a firm no to floral foam. I’ve learned to create fabulous floral displays without any of the harmful chemicals or waste, and I’m proud to be part of the movement toward a more sustainable future for floristry. We can can create fabulous displays with none of those nasties!
