a few weeks ago i bought a baby redwood. It was about two feet tall, with a few branches. as soon as i got it home, i put it in a planter. the place i got it from said that it didnt like a lot of water, so i gave it a big splash of water every 2-3 days, instead of every day. well, ive noticed that one of the lower branches is wilting, and i would hate to have my tree die on me… any tips?
