FROST AND YOUR OUTDOOR PLANTS

Protect your plants from night-time frost

It’s understandable - in your enthusiasm for greenery you've filled half your garden or balcony with new plants, particularly flowering annuals. It all looks amazing, but eek: night-time frost is forecast. What now?

NIGHT-TIME FROST

Firstly, what actually is night-time frost? Night-time frost is quite common, when the temperature drops to below 1 to 2 degrees Celsius. A lot of outdoor plants are not affected by it, but flowering annuals like daisiesbegonias and geraniums that have just emerged from a nice warm greenhouse can be bothered by it. That also applies to Mediterranean plants like the citrus tree. The risk of night-time frost diminishes tremendously after the middle of May.

WHAT CAN GO WRONG?

Frost can cause frost damage: water expands, including the moisture in your plant. This causes tears and splits, and your plants are damaged. Frost damage can also be caused by a cold wind, incidentally. Plants in pots are at greater risk than plants in the soil. So protect them!

PROTECT YOUR PLANTS FROM NIGHT-TIME FROST

Firstly place your plants in a sheltered spot. You can also wrap them up to protect them, e.g. with a fleece blanket and a couple of clothes pegs. Newspapers can also help to keep your plants nice and cosy. As soon as the frost has departed, remove everything again so that oxygen and sunlight can get to your garden plants.
