Plumb Tree Damage
This is a Santa Rosa Plumb. Quick story behind it.
I planted this plumb in the spring of 2004, before hurricane Ivan pounded us. We had 130+ winds. The growth appeared to be stunted the following years to come. I kinda wrote it off. Last year I planted some fish beside it and it exploded. It added around 3.5' of growth over one season.
Now I'm paying close attention to it with fertilizer and mulch. I have damage to it. I'm almost positive the wounds were from the lawn mower deck hitting it over the past years. My question is, should I me treating the wounds with something? Could it be I'm wrong on the mower deck causing the wounds?
