Taylors Bulbs director Adam Taylor said sales to garden centres were very strong in August. One customer had reported sales eight times up on last year, and another 2.5 times up.
"August is really a set-up month, with the main sales period still to come," said Taylor. "Customers are reporting to us that it's autumn already. The peak selling months are September and October, but if you can start off well, things will hopefully stay that way."
He added that a lot depends on how retailers react. "Bulbs are an impulse product and if centres get them out on the shelves, people buy them."
There has also been interest in onion sets, with many customers asking for them.
