We have a Japanese camellia tree/bush on the side of our house, approximately 7 ft tall, and the trunk is about 6-8 inches in diameter. The trunk is 3 1/2 ft away from the foundation (concrete slab). My husband wants to take it out as he's convinced it's too close to the house. I don't want to remove it unless absolutely necessary as it produces the most stunning flowers. I can't find anything conclusive about how close they can be. Does anyone have any thoughts?
