Feel free to do some light pruning with the understanding that yes, it may impact the blooming potential of those particular stems but not of the unpruned stems. The Limelight Collection does not contain any cultivars that bloom early or very early. Therefore, if you prune quickly now, it is possible that even the pruned stems may still blossom, albeit later than usual or after the unpruned stems. This can vary by geographical location and time of year.
