Talking with a bloke in the supermarket a few days where he was saying he's been tapping some of this Silver Birch trees, he reckons the syrup is not as sweet as Maple and much prepares it . I dont have any growing here but they grow so fast that getting a few Birches growing could be worth doing.
richardw, I find the silver birch likes it when there’s good soil mositure. They grow almost as fast as acacias here. What size (girth) do they have to reach before you can start tapping them for syrup? Box elder (Acer negundo) makes good syrup so I’ve read. They’re too weedy for my liking so silver birch might be just the ticket.

Recent research on sugar maples shows that the trees can be quite small--they are apparently pumping soil moisture up and into sap very aggressively in the springtime, and a single tap in a small tree is OK. Then again, it does seem like tree cruelty to tap a very young one.
Growing in a coastal zone 7a in the Northern Hemisphere. Hot humid summers and cold snowy winters. Plenty of rain. Sandy loam topsoil over clay subsoil, whatever the glacier left behind when it made Long Island.
