Had some warm weather around a month ago and my outdoor elm, which I've had for +5 years, started to wake up and grow like crazy. A few weeks later, we had one day where it was ~40 degrees and since them my Chinese elm stopped sprouting new buds and has dropped quite a few of it's new leaves. It's never woken up and then quickly gone dormat again, so I just want to make sure it'll be okay, or if there's anything I should do. Thanks!
