A week before Christmas, I bought a young live Christmas tree. It is in a pot on our balcony. Starting spring season, the tree started growing beautifully and spreading green little brunches. Last week I noticed white cottony things covering some of the the brunches. I am not sure if it's a web or fungus. It is white and dense, covering the needles too. What can I do about it? I would appreciate your help.

It's an insect pest, likely from scale insects. You can remove infected areas, of not too much. Also, treat the tree with neem oil. It is an organic insecticide that doubles as a fungicide and should take care of the problem. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
