Planting near a furnace exhaust vent
I am a total gardening newbie and getting going in the backyard of my new house. I want to plant a small Japanese maple next to my house but am worried about the exhaust from my furnace and gas water heater. I gues trees don't mind CO2 but i wondered if the hot air might cause damage in general or mess with the tree's dormancy somehow in the winter.
Anyone know how much clearance I should have? I was thinking 5'
