@ublaszko We bought it in October and it sat in its pot until spring when we got it out and planted it by a fence. We then dug it out because a plant by the gate was accidently killed off and we needed our privacy, plus another plant had grown up next to it and we thought we'd keep it (since discovered that this was elder, which we need to get rid of soon). The roots had grown out of the pot shape slightly when we dug it out but it seemed to be fine, and its been a few weeks since planting.
I think it probably needs more water since it hasn't had a chance to establish yet so it won't be drought - tolerant until next year. Keep the soil moist but let the top inch or two dry out between watering. 👍 It's probably just stressed out.
