Question
I have a flowering dogwood planted in well-drained soil,partial sun & shade in lower Michigan. It  has a variegated leaf but only bloomed once in the last 7-8 years.It's in excellent health other than that. Has beautiful leaves but never flowers. Can you advise me ? ?Thanks

Answer
fertilize dogwood Camellia-Rhododendron food,
acid based fertilizer, right after they bloom. I can usually expect to see flower buds start to form about 2-3 months later. Or you can use 0-10-10 fertilizer
in early to mid-Summer to help induce flower bud
formation. The problem is the nitrogen use a fertilizer that is low in nitrogen.
Normal lawn fertilizers are high in nitrogen and the tree maybe getting too much nitrogen from the lawn fertilizer. Broad cast the fertilizer around the tree under the foliage and water in. Use 1 cup per inch of tree diameter.
