Where to plant baby hydrangeas?
Two days ago I found a nursery on Ebay that was selling these baby nikko blue hydrangeas for $3! I LOVE nikko blues! I couldn't pass up on that as I don't mind their little size and enjoy raising plants, so I bought ten of them. They came in today. They appear quite healthy and have lots of roots growing out the bottom of their little 3" pots.
Looking at our weather forecast it would appear (Fingers crossed) here in my area of Georgia that our last frost/freeze will be tonight. I've brought my babies in tonight.
My question is this: Once danger of frost is past, the rest of the nights here for the next month or so look like they'll be in the 40s-50s. Are these baby hydrangeas big enough to be planted outside and able to handle those temperatures, or do I need to plant them into larger pots that can be brought inside at night until it warms up more (Late spring, early summer?) and then plant them into the garden?
I attached an image so you guys can see their size.
Thanks so much everyone! :)
