 has said. Temperatures could be as high as 90F (32C) this week, following weeks of washout weather . As well as enjoying the sun, anyone who has planted blight-resistant tomatoes 'will be rewarded for their foresight' with a glut this week, said Guy Barter, the RHS's chief horticulturist. Sweetcorn also thrives in hot temperatures, when their photosynthesis works best. 'This is going to give it a very welcome boost,' said Mr Barter. 'In other years the sweetcorn gets to October and it's not right and the flavours never quite as good. But it's paid off this year.' Other varieties will not do so well out of the heat, particularly cruciferous varieties and salad leaves. 'Things like cauliflowers and cabbages and lettuce will mature all in a rush, which is always a pesky nuisance,' said Mr Barter.){kind=link}
