Q.Norfolk pine tree
HElP ME!! My Norfolk pine is turning yellow and Brown . Should I cut.the branches off or what? I don’t want to kill it. Linda Heath

Norfolk pines require high indoor humidity which is difficult to achieve during months that the furnace is on. Misting is only a temporary measure so the key is to find a place that gets sufficient light and humidity. Clustering indoor plants together may help as well as setting the plant over a tray of water with pebbles in the tray. You don't want the plant itself to sit in water as too much water causes browning of needles. So does too little water! I think this plant needs a larger pot and careful watering. There must be a drainage hole in the pot. I would not prune because it isn't certain the entire branch is dead. Needle drop may be followed by new needles. (This isn't a true pine tree.)
