Q. What is the best way to acclimate a blooming hellebore houseplant to outdoors before planting it?
I have a shade garden here in central Kentucky.
Hellebores are gorgeous but not natural houseplants, so they do not always make it through the transition to growing outdoors.
Find a spot in your home that is cool but has bright light and move your plant there soon. Something like an enclosed porch or unheated garage that does not freeze will work well. The plant will prefer the relatively cool conditions. If you notice leaves turning yellow, it is too warm. Water lightly, allowing the soil to dry somewhat before watering again, but don't let it dry out all the way.
Wait until spring to make a full transition to outdoors and take about ten days to gradually acclimate the plant to days and nights outside before planting it, after the last frost date for your area. Good luck!
