It should get more leaves in a few weeks. There are lots of trees in Denver metro that got frosted. Part of the problem is that it was a very mild winter and trees leafed out earlier than normal. Hopefully there's not another late freeze that gets the new leaves.

There's been a couple springs that the big locust tree in front of my house didn't get it's second set until June.

All the leaves on all the honey locusts in my neighborhood got whacked by the snow storm, all shriveled up and falling off now. I guess their leaves were just too tender and new. The other trees with larger leaves (even my peach tree) seem fine.
