Getting hardwood in stardew valley is going nowhere

And don't sell any. Robin's second house upgrade wants 150 hardwood on top of the gold, so bank that first.

secret woods. north end of cindersap forest, there's a big log blocking the way in and you need the steel axe to break it. inside are six large stumps that come back every day, copper axe is enough for those and each one drops 2 hardwood. go every morning and it adds up fast. later on mahogany trees give hardwood when you chop them, so plant a few on the farm.
