Sollte ich diese von meinem Baum abnehmen, bin ich gerade in mein neues Zuhause gezogen und bin mir nicht sicher, wie ich mich um den Baum TBH kümmern soll

It’s doing fine. Water in summer. Dry leaves mean dry plant. I wouldn’t wind lights around any tree.

The lights were put up by my recently passed grandad so if everyone would like to keep their opinions on the lights to themselves that would be very much appreciated!
