Growing tomatoes in a cool or maritime climate can feel like an uphill battle. It doesn’t have to be.

In this episode, I’m joined by tomato expert Holly Farrell, author of The Tomato Grower’s Handbook, to talk about how to get reliable, flavourful harvests even when summers are mild, damp, or unpredictable.

We dig into practical strategies for gardeners in places like coastal Canada, the UK, and the U.S. Pacific Northwest—where heat is limited and blight is always lurking.

In this episode, you’ll learn:

Why variety choice matters more than anything else The difference between bush (determinate) and cordon (indeterminate) tomatoes How to use microclimates (walls, courtyards, sunny corners) to your advantage Simple ways to add protection—from cloches to greenhouses How to reduce risk from blight in damp conditions Tips for growing tomatoes in: Balconies Containers Garden beds Tunnels & greenhouses How to deal with wind exposure (especially coastal winds) Holly’s favourite tomato varieties for different uses If you’ve ever struggled to ripen tomatoes or deal with disease pressure, this episode will give you a clearer path forward.
