I was saying that if you want to start a cork supply business (grow cork trees because you see an increased demand), you'll have to wait for at least 25 years to make any cork at all, and probably 35 years to make any revenue.

A tree reaches maturity after ~25 years after planting, and the first harvest is usually low quality, so it doesn't bring money. After the first harvest it can be harvested every 9-10 years, and you can do so for hundred of years (a healthy cork oak can live for 5-600 years).

Cork does grow on trees, but slowly :).
