Just keep them really well watered as they are taking root. You probably won't see much vegetative growth happening for a while, but they should be ok. They are pretty hardy plants and will multiply like crazy once they get established. Giving them some temporary shade would be a good idea, even if it's just an umbrella or something, shading them from the hot afternoon sun would be best. Also, you made sure not to bury the crowns right?

Once they get rooted well, give them some fertilizer, they are fairly heavy feeders.

Thanks for your advice. Most of the crowns are set about right. I was moving quickly and a few crowns may be slightly above the ground. I mulched these with compost when I realized my mistake so I'm hoping they'll be ok. At this point I doubt it would be worth digging up to adjust.

Yeah, I wouldn't dig them back up, a bit too high is probably better than too deep.

Good luck
