Tigwell added: "Garden furniture isn't growing quite as fast in percentage terms as bird/wildlife care, but these are high-value sales when they are achieved.
"If garden centres put down less space to outdoor furniture then they could do more on the indoor ranges. The market has probably got quite a bit further to go, especially if centres look at Swiss garden centres and how they sell all the soft-furnishings alongside the key products.
"But it will be like most band-wagons: people need to get on it fast and then move out before growth begins to slow, as it undoubtedly will," she added.
Tigwell said garden centres are still a long way from selling hotspots and need to recognise the value of the best selling places in their shops: "I suspect that some of the larger centres have looked at this, but the large number of suppliers and changing seasons makes, it more difficult than in the supermarkets and even they have had some trouble with it," she said.
