have two new weeping cherry trees. Within two weeks. Problem is
the leaves on both trees are turning brown and wilting. They appear
to be dying. I am new to this. Does this mean my trees are going
to die, or is this normal?
asked our landscaping and arboriculture expert, Jim Antill, for
his thoughts. Jim says:
If you mean the leaves
went brown within two weeks, there could be several reasons, depending
on the time of year you planted. If it was in the late autumn they
were planted, they could be naturally shedding their leaves, as
all cherries do in winter.
But it sounds more likely
that they are getting either too much water, or too little. If the
hole they are planted in does not drain properly but the tree is
still watered, the roots will be standing in water and they will
die. Roots MUST have air: roots in water, no air. Roots die, tree
dies. It only takes a week!
On the other hand, if
they are not getting enough water they will shed their leaves to
try to prevent water loss, and so save the tree. If you water it
in time, the tree may lose its leaves but hopefully will grow some
more. This problem is most common with summer planting.
