Giant Sequoia turning Orange-Yellow
I need help with my Giant Sequoia. I bought it as a sapling and it is now about a foot tall. This is the first full summer I have had it. I live in southern Michigan and our summers are hot (80-95) and very humid. My giant sequoia is planted in a pot and it gets about 12-13 hours of sunlight a day. I water it when the soil feels dry, which is almost every day.
The bottom needles of the tree are beginning to turn orange and yellow, it looks like it is slowly creeping up the tree. The new growth at the top of the tree looks fine.
Does anyone know what could be wrong with it? I'm thinking maybe its too humid in Michigan?
Thanks in advance!
