Its latest idea is a Horticultural Enterprise Pack, which went out to schools in March. The boxes, supported by Westland Horticulture, include compost, seven types of seeds, seed trays, pots, plant labels and growing advice, along with tips on ways to use the "garden centre in a box".
Woodcote Green also promotes school vouchers, each worth 25p and given out with every £10 spent. Newsletters, advice and curriculum links supplements the packs. The annual Woodcote Green Horticulture Show encourages children to show off what they have grown.
Explaining the centre's approach, Barnden says: "We don't only do things for profit. But a school satchel is a powerful tool - there are 70,000 parents and grandparents we can reach that way."
