We had a dogwood tree planted last year. It has brown and crunchy leaves from last season and it appeared to be dead. This evening, I noticed a few fresh, green leaves at the top of a couple of branches. Does this mean it's coming back? Should we give it a chance? Seems late in the season for new growth. This one is in full sun. Our other dogwood tree in the back corner of our yard (with more shade) which we had planted at the same time, has had flowers for weeks now.
