Those roses are the "bare roots" that some folks sell... I recognize the plastic pot from HD in pic #2 from your OP. Since you're in Walnut, CA, it's extremely late for bare roots here, but you're doing well so far. January is our normal bare root season in So. Calif. The advice above is perfect, but I'd really emphasize watering them like crazy now, and maybe putting up some sort of shade situation for them for awhile until they get their roots established. We're having really mild temps now, but if they're in full sun in Walnut, you need to be careful with them. Water and shade.
