The eventual needle drop is inevitable, but if your tree seemed fresh when you picked it and now is shedding a lot of needles, it’s likely been placed in a room that’s too dry and hot. Combine this with insufficient watering, and your tree will begin dying too soon. Greg Wash advises that 'if you notice your tree is beginning to shed more than usual, check the water to see if it's too low and check if you put it next to a heat source that you could move it away from.'
