I got this dawn redwood delivered to me from Brussel’s back in the spring. It leafed out great but as the summer went on it slowly dropped all its leaves. It has been putting out new buds for the last 6 weeks or so but they aren’t really opening, they have just kind of stalled. It had been in full Florida sun but I recently moved the tree to partial shade. It doesn’t look sick but it also doesn’t look great. I don’t have much experience with these, any tips?
