Lemon tree issue

[Anniekay]

Big no- no to put it in a bigger pot. Now you have lots more soil to stay sodden wet. Just do not water it any further and do not repot a declining plant into new wet soil, particularly a lemon that grows in free draining sandy soil by nature.I

Yes cut off the dead black parts, like I said, to green stems.

Ok I've cut them off but on this existing pic before I cut them off zoom in whats that on the stem it's green but looks like it's turning a different colour

Try using your fingertip to test the moisture. If it's not dry 1-2" down, do not water. The stems are still plump, so it hasn't given up yet

Fall plants don't need watering like in Summer. Matter of sticking your finger see if it's moist.
