As far as I know, JM leaves will not become red again once they turn green. Many varieties are red when they leaf out in the spring. Some retain their color if they get enough sunlight, others will turn green at some point or another regardless of sunshine. If your Red Select puts on any more new growth this year, the new leaves should be red (unless it was mislabeled). Next spring, the entire tree should be red and stay that way at least through spring and early summer. However, it might still green up some as the summer progresses.
