Hello, all. This is my first trip to this excellent site. Our Kousa Dogwood, planted in 2004, developed bracts in 2005, few in 2006, and none in 2007. It's too early for them now (southern New England), but we're, well, worried about the tree's health. Its foliage is O.K. It's in full sun, in mildly acidic soil. Do you have any insights into this? Many thanks, R
