Gardening in August and September
July brought a heap of snow to the alps, and the ground temperatures are down, so expect the spring bulbs to be a little later in showing their colourful heads.
Remember Fathers Day 3 September this year. Check out our Facebook Page to go into a draw for a Free Fathers Day gift – Mid August
