How do you distroy trees in Harvest Moon DS?
You need to get your axe up to 400% skill level and then go tot he bottom floor of the 1st mine and get your hammer and mine some mystrile ore. Come back out and phone baibara the blacksmith (after 11:00 am)and tell him you would like to upgrade your axe. He will then ask what ore you would like to use, tell him mystrille. He will tell you it costs either 2000g or 3000g and takes 3 days.Then when you get your axe back you should be able to chop down trees.
