Q: I planted a 1" diameter Red Maple in April. Also I had
sod installed just before that.
So I had to water it every day for the
first few weeks. Then every other day for another couple of weeks.
problem I'm have is that the end of the leaves are turning black. There
is some new limbs and leaf growth. Any idea what the problem is?
Too much water in the soil forces oxygen out of the pore spaces. Roots
require oxygen in the soil to survive, so the end result is roots that are
literally drowning because there is too much water.
I realize you had a lawn to keep established, and watering was a must.
However, if you can water the tree separately from the lawn somehow, that
would be better for the tree.
At this point it is a wait-and-see situation to see if the tree will
recover. If it does, only water once a week, applying 1" of water each
time, during any extended dry spells.
