Question: 548-2111
We have some sixty year old pink dogwoods that are a little weak this year. Six or seven years ago you recommended a fertilizer treatment and they perked up. We had an arborist inject the trunk with a liquid infusion of nitrogen. What could be the problem? Pattie, Norwich, CT

Mort's Answer:
It is time for another supply of fertilizer. I am assuming that the arborist did not find any earwigs in the bark. Nitrogen is a good quick fix. You should use a granular fertilizer like 5-10-10 or 5-10-5 to supplement the nitrogen. Drill about ten holes a foot or more deep in a circle ten feet from the trunk. Fill the holes with the fertilizer. You will need about 50 to 80 pounds.
