Frost Dates

Facts about Frosts

There is a difference between ground frost and air frost. Many plants can survive a ground frost, as it’s just dew freezing on the ground. An air frost is much more damaging to plants, so don’t freak out if you hear that there’s a good chance of a ground frost, as most plants need only a little protection from it, if any at all.

Where you live. Basically, the higher up you are, the greater the risk of frost. The further South and West and the nearer the coast you are, the less risk of frost there is. If you’re an urban gardener you can also get away with more (murder if you live in London….)

UK Frost guidelines. So even once all these variables are taken into account and then with the impact of climate change on top, we still figured it would be helpful to have a bit of guidance on the subject. We’ve searched high and low for a decent table of dates on the internet, but we haven’t found anything easy and reliable to use, so here’s our own easy-peasy, at-a-glance guidelines for UK frost dates.

No guarantees, but hopefully this will help and keep your eyes on the weather forecast. Give us a shout if we’ve got anything horribly wrong……
