With more than three decades in the garden industry, Paul Zimmerman explores the passion that connects gardeners around the world with those who also live it. Drawing on years of travel, conversations with growers and garden makers, and countless visits to gardens across continents, Paul looks beyond the “how-to” and dives into the deeper questions — why do we garden, what’s changing in the gardening world, and what does it reveal about who we are?
Bringing Plants, People & Ideas Together with Peter Rijssen
What does it take to get a plant to your garden center and into your garden. It starts with the plant breeder and if that plant is interesting a whole system kicks in.
My guest on this podcast is Peter Rijssen owner of Plantipp, a company based in The Netherlands that represent plant breeders. He acts as their agent.
It’s a great insight into what goes on behind the scenes before plants ever reach your garden

"Roses Are Hard To Grow". How Did We Get Here-How Do We Get Out?
I believe most gardeners want to grow roses, but many are intimidated by them because of their reputation for being difficult.
Matt, Jason, and I look at how roses got this reputation, whether it’s still deserved today, and what all of us who love roses can do to make growing them easier, more approachable, and a lot more fun.

The Everyday Rose Show. A Discussion About Rose Rosette Disease
Raising Funds for Rose Rosette Researchhttps://charity.gofundme.com/o/en/campaign/raising-funds-for-rrd-researchThere is a lot of information, and misinformation, about Rose Rosette Disease. I held a discussion with Dr David Byrne, Dr Kevin Ong and Dr Mark Windham to talk about RRD. We talked about it's history, what spreads it, what does it look like, tips to prevent it and what to do if you get it. We also answered questions provided to us by gardeners like you.The research they do is generally funded by grants. This year, (2020) they did not get the grant so we have set up a Charity Go Fund Me Page to help fund their research. In cooperation with the AGRS™ (American Garden Rose Selections™), a Charity Go Fund Me page has been established and you can donate now to help with this effort. Please make a donation to this vital work.gofundme.com/f/raising-funds-for-rose-rosette-disease-research
