Whilst the weather is turning and we start to think of Al Fresco dining once more. Some have tried the BBQ but it hasn’t quite been warm enough just yet. My gardening instincts remind me that it is of course possible to have a frost up until the end of May so be warned. The ground is not quite warm enough yet and any sunny days with open blue skies end with the heat of the day being sucked out into the atmosphere and the cold air from the ground with it. This can result in the lower branches and leaves of newly growing plants suffering from what we call an aerial frost.
