They may be quite rare in recent years but when the UK is hit by a heatwave, it comes in force. Here are just a few tips on how to deal with plants in hot weather. Here are just 4 effective ways of dealing with a heatwave.
In the greenhouse cover the glass with any form of shading. On my greenhouse I use an old bamboo blind which is draped over the roof. Shading is readily available from places such as amazon (http://amzn.to/29KrxQ3).
PAINT THE GREENHOUSE
Traditionally gardeners would paint the greenhouse glass using a water version of shading. Simply ‘paint’ the shading onto the external glass surface (http://amzn.to/29IYlg0). At the end of the season you scrap the paint off – this can be time consuming.
PROTECT THE PLANTS FROM WITHIN Recommended Method
This year I’ve been using, and having great success, with ‘Chill Out’ – based on natural plant extracts it alters the plants natural reaction to hot weather. You water it onto the plants and it allows them to grow in temperatures over 30*c and therefore avoids wilting. “By changing the plant’s reaction to heat stress you can get continued growth and the plant can thrive high temperatures.”.

I like to water at early morning and to give everything a really good soak. Not just one or two watering cans over the flowers and veg but several. Don’t forget about crops like fruit trees, bushes and potatoes. In the greenhouse throw a few buckets of water over the floor to cool the temperatures.
