Protecting your garden
Last frost dates

First and last frost dates are imperative for gardeners, but can you tell when the last frost will be this year?

Frost dates refer to days when temperatures fall sub-zero and conditions become cold enough to damage or kill your plants.

They are important to know, because although it is astronomical spring from tomorrow, spotting the first signs of true spring-like weather, and consequently when to start sowing plants, can be tricky to pinpoint.

Last frost dates are based on historically averaged temperatures, but are never a one size fits all scenario. The dates depending on your location's altitude, latitude, and urbanisation, with dates ranging from end of March to mid-May.

While you can certainly search up the average last frost date, which is generally a ten-day window, they are only an average and not a definitive. If you are worried about a frost after planting, you can use a fleece to protect your tender plants.

You could also add a layer of mulch to your vegetable garden, watering frequently, which will provide an added layer of warmth and natural frost protection.

Vegetables like lettuce, carrots, cabbage, spinach, and radishes are better at withstanding lower temperatures. Other, warmer-season crops like cucumbers, tomatoes, and peppers will likely struggle, so timing is imperative.

The coming days look set to bring fluctuating temperatures to the UK and Ireland.

If in any doubt, wait a few weeks after your area's average last frost date, to give your plants a stronger chance from an unexpected frost. Keep your eye on the TemperatureRadar up to four days ahead too!

The image shows an intense tropical cyclone over the western Pacific, east of Taiwan and the Philippines. The centre of the system is depicted as a light purple and white vortex with a clearly visible eye, surrounded by a ring of red and orange areas indicating the strongest wind speeds. A white arrow marks the typhoon’s predicted track towards the north-west, in the direction of Taiwan. To the west of the storm lie the Philippines, with the cities of Manila and Cebu; to the north of these lies Taiwan, with Taipei. Further west, the Chinese coast, including Hong Kong, and parts of Vietnam can be seen. The coloured wind map shows predominantly green areas outside the storm’s core, indicating significantly weaker winds. White streamlines illustrate the typhoon’s anti-clockwise circulation in the Northern Hemisphere. The highest wind speeds are concentrated around the eye of the cyclone.
