Q.Is my Japanese Spirea dead?
We planted three Japanese Spirea (Magic Carpet) plants about two weeks ago. Within a couple of days, all three of them turned a brown/gray color (see photos). Are they dead or just in shock? Is there anything we can do? Everything else we planted at the same time is fine and not having these issues. Thanks for your help!

The soil looks to be a bit on the dry side for a new establishing plant. Make sure to keep these watered, letting them dry out slightly in between, until it is established.
Most spirea have very similar care no matter the variety. This article will give you general care of these: https://www.gardeningknowhow.com/ornamental/shrubs/spirea/growing-spirea-shrubs.htm

We have monitored the soil regularly and have watered them as suggested since they were planted, so dryness is likely not the issue. We think that it may be some sort of transplant shock, and are wondering if anything can be done about it or if they appear to be dead. Thank you!
