Morrisons has launched a voucher scheme that aims to teach children where food comes from and encourage them to grow their own fruit and vegetables at school. The Let's Grow initiative gives customers a voucher for every £10 spent. These can be exchanged by schools for gardening equipment from seeds and spades to composting bins and planters.

Vouchers can be collected until 6 November. The supermarket has partnered with charities Farming and Countryside Education and the Federation of City Farms and Community Gardens.
