Q.Pink flowering kousa dogwood producing very few blossoms
Help! I planted this tree two years ago, fertilizing with acid fertilizer in the spring and fall. The tree is growing well and appears healthy, but produces only a few blossoms (two dozen or so). What do you recommend?

My dogwood did not blossom too well this spring either due to the cold spring we had - the blossoms are very tender to the cold. Drought could also affect blossoms. These and other reasons are discussed in the following article:
