I just purchased this Dawn Redwood a couple weeks ago. It has started losing needles at the tips, they dry out and are crispy. See the attached photos.
As I see it, a few things may have caused this. One, it is root bound and I had to cut some roots to remove it from the nursery matting it was on. Two, I had to leave town for a few days, but left it on a dripper system , but it may not have received enough water? Three, I was fertilizing some other plants and hit this one with some inorganic fertilizer. Could this be fertilizer burn?
So, solutions. Would repotting now help? Into a larger pot with pumice or something inorganic? I’ve been watering more frequently. It’s in a smaller 2 gallon pot.
This is my first post, and I’m very much new to this, so if this should be posted elsewhere, please let me know.
Thanks for any help,
