Fast growing, climbable tree?
We have a large backyard, which has a 30'X40' spot that gets mostly sun during summer -- I haven't noted its exposure during winter. I'd love to plant a tree with a low and strong enough branching structure that my kids could enjoy climbing it. A fast grower would be a plus, and double (but low priority) bonus if it would get edible fruit. I have no idea or knowledge regarding growing trees, so any guidance and/or pointers would be much appreciated. Thanks in advance!
