Q.Japanese Maple Tree
Our 7 year old Japanese Maple Tree got hit by frost last week.
It had filled out nicely already. We had already put in fertilizer spikes for spring and use them in fall as well. We are trickling the hose for an hour to try to revive it. We typically trickle the hose any week we do not get rain.
What more can we do and what are the prospects for recovery?
Avoid overwatering. Once a week during dry spells. Pull the mulch back from at least 6 inches away from the base of the trunk. Mulching is good, but always keep it pulled back to avoid disease.
