Jobs for August

Your garden should be in full swing and you’ll be waiting patiently for your Tomatoes to ripen, your Sweetcorn to sweeten and your Cucumbers to swell, all of which should be starting to happen by the end of the month. You should be seeing the first fruits appear on your Pumpkins and your Autumn Raspberries should be in flower!
