The credit crunch trend for growing produce at home has helped garden centres increase sales by 10%.

Sales at garden centres and nurseries rose 10.2% in the three months to May, according to the Horticultural Trades Association.

The upsurge in demand had been driven by increased interest in home growing, with children involved in school gardening projects using 'pester power' to get their parents to buy seeds, said the HTA.

Sales of pots, canes, compost and other garden-related items had also risen, the trade organisation reported.
