I believe that the tree has to be a certain height before you can sit. This depends on how long you play Animal Crossing. The tree grows in stages. Once you have played fifty days and you've played for fifty hours, then the tree will grow again and you can sit on it.
The way the tree grows is hours played / days played. Here's a visual guide for you
Once you hit the 50 hours played / 50 Days played, you can sit under the tree.

i think it's worth noting that the 50 days isn't just more adding on to the 50 hours. it's basically playing on 50 seperate days. so if you play for an hour a day for 50 days, your tree should get to that size. or you could time travel and play for a few hours straight or something.
