The shortest day of the year (21 June) is the time to start thinking about planting garlic.
Look for a well-drained spot - pots, hanging basket or any available space in your raised garden will suit. Add some compost, a little bit of potting mix and mix in some Nitrophoska Blue fertiliser. Plant single cloves twice the depth of the actual clove, compost over the top and don't fill in with soil. Your garlic will be ready to harvest around the longest day on 21 December.
