Growing season in UK boosted by a month

Climate Change, UK Climate Change

The UK growing season for plants is longer than at any time since records began in 1772 extending the range of flowers and vegetables that can be grown successfully in the UK.

Six of the ten longest growing seasons have also occurred within the last 30 years

During the last 10 years the ‘plant’ growing season, according to the Central England Temperature (CET) record, has been on average 29 days longer than the reference climatology period 1961-1990, according to Met Office figures released on World Meteorological Day [23 March, 2016].

The increase in growing season length is largely due to the earlier onset of spring, warmer temperatures into late Autumn and the reduction of regular frosts in the winter.

The earliest start of the thermal growing season was in 2002 when it began on 13 January. The longest growing season in the 240-year series was 330 days, in 2000. The shortest growing season was 181 days in 1782 and 1859. In 2012 the thermal growing season was 282 days, up from 279 days in 2011 and above the 1961-1990 average of 252 days.

Predictions are that the growing season could lengthen by a further two months by 2050 . In some southern areas , the growing season may even run continuously all through the year.

The effects of climate change on gardens in the UK will be challenging, but there is a silver lining – we might be able to grow a different range of  plants and flowers – what an exciting future for UK gardeners!

I am not an experienced gardener - more of an enthusiastic amateur who learns by trial and error and is keen to "manage" the effects of the weather on my garden. Writing this blog is my passion and I hope that it will continue to grow, allowing global gardeners to communicate about the effects of climate change on our plants and the future of our gardens.

    Hi Debbie – it certainly has, and very warm at the moment, so feels rather strange bringing in all my tropical’s when its so darn warm – I just don’t want to get caught out when I go away in a couple of weeks time. You should post this on the UK Hardy Tropical’s forum as well – best of wishes to you – Will

    Hi Debbie,
    Just read your post and it seems so appropriate. Here in New Zealand we had a very short spring and rushed into summer at the beginning of November. Currently at the end of January we have just had 3 months of almost no normal rain – just some rain storms in various places – and very hot temperatures. We have just as a country had the hottest January since records began. It is a great growing season but without the rain has meant the need for watering to keep things growing. I’m now deciding that everything I put into the garden will need to be able to withstand prolonged hot dry periods. I see that the Northern Hemisphere is currently in a prolonged intense cold. We need lots more people writing about it. Thanks for your blog. Margaret
