If you don’t want the blackbirds to eat your strawberries, keep them well covered. I plant strawberries 30cm apart in each direction, mulch well with pine needles to keep the fruit clean and to deter slugs and snails then cover with bird mesh. Nails in the side of the raised beds keep the mesh in place.
These carrots were sown in mid-June, harvested late October from the tunnel house. About 20 carrots from a 30cm square planting (twenty five seeds sown in a five by five block).
