I'm in zone 5b (Central MA). I know the optimal time for planting trees is fall and early spring. It being the middle of May right now, I'm thinking I may have to work hard to keep these trees alive.
I've planted them on a slight mound with an inch or two of mulch with a berm at the top of the mound (I guess it is to help retain water there. I did it because people said to :).
The tree is about 5 feet tall with no leaves or anything yet.
Also, how long should it take before I see some form of life, like leaves or some sort of growth.
