In the absence of local asparagus, supermarkets would fill the shelves with imports, Falloon predicted.
"It looks like asparagus but it tastes like cardboard. Imported asparagus is picked before it's fully developed and the vegetable draws on its existing sugar supply in an effort to grow."
Falloon, who has been growing the vegetable since 1979, said land was much more affordable in the South Island and the Asparagus Council was hoping to lure southerners into the business.
It was not a bad lifestyle, he added, with just 100 days of hard work each spring during the harvest.
"The rest of the year, there's little to do," he said.
