Peach tree leaves dying
HELP! The leaves of our peach tree (7ft tall sapling, grown indoors) are turning brown at the edges. Also a few have holes in them and look slightly withered. What is wrong with our tree and how do we cure it? Beginner tree parents (couple) - first co-ownership of an organism. V important. Tree's name is Penelope (Peregrine Peach) and we love her very much. Have been watering when topsoil feels dry, and using multipurpose fertiliser (nitro rich).
