Could do with a bit of gardening advice, if this is the right place to ask ...
We have a willow tree in our garden which grows like the proverbial weed and needs frequent taming. Yesterday I approached it brandishing my secateurs and a small saw and realised that several of the main branches were black; several of the others were showing signs of becoming black and some were sticky and red. Is this an infestation, a fungus or something else?
I have now cut it right back, leaving the few healthy branches (it usually grows back very quickly) and sprayed the remains with a multi-purpose bug killer, as I thought that wouldn't do any harm.
Any thoughts? Should I just dig it out ask MrOurKid to dig it out, or wait patiently till next Spring in the hope that it will be ok?
Thanks for any ideas.
