I'm new to the forum and not an expert gardener. Can anyone help explain
why a 10 year old weeping willow has died. It has been healthy and
undisturbed, but all this years new growth has died. The only
difference is this year I planted petunias around it? would that cause
a problem. We have not been flooded, nor have has it been too dry. Any
help would be appreciated though I fear too late for this tree but I
will be replacing it and would like to avoid facing the same problem.


Can't really say, especially not from this amount of information. You
could propagate this plant from cuttings, fairly easily (My parents
planted ours simply by pounding a branch end into the ground, and
keeping it watered!)

Generally speaking, trees take several years to die, so what started
this may have occurred several years ago.

In the US, I'd encourage you to take a sample to Extension Service, but
I don't know who would perform a similar service in the UK. Have you
a botanical garden or a good nursery nearby?
