Lemon Tree in big trouble

[veggiechicken]

we reduce watering down in the winter (keeping it just moist) and tend not to feed over winter, just start feeding again about late April and give a last feed around when it starts cooling down and threatening frosts outside..

Everyone goes on about summer vs winter food, and yet baby bio citrus feed is highly rated and claims to be used winter/summer. This is what I've been using. Additionally Jimny14 doesn't feed his at all.

Just to clarify, Jimny does feed - but not over winter.

I had a lemon once, it survived a couple of years, produced one lemon, had lots of sooty mould so I put it outside as punishment. It died.

Beware using vine weevil soil drenches on edibles. The one I used stayed effective in the plant for months.

Biological controls would seem to be the safest way to go.
