How low a temperature can my coleus tolerate in Michigan? Temps dropping tonight. Planted coleus about 10 days ago, looking pretty healthy. However, temperatures are predicted to drop tonight. I'm very concerned. Do I need to cover them?

Subjecting coleus to temperatures below 50 degrees is not advisable - so I would definitely cover them.
