Congratulations and keep monitoring the weather in Ohio. We have gotten past my avge last date of frost by a few weeks and the coldest in the next 10-days is forecasted to be 41, so I am hoping things will stay as they are, more or less. In mid February, I moved out all the inside potted plants to the outside and reversing that now would be a pain. Cover it if a frost is announced and you have still have it outside (but better to bring it in).
An early-blooming but unknown lacecap that was supposed to be a Nikko Blue Hydrangea started the broccoli phase about 3 weeks ago!!! Weird, man. The weather this year is just way off. I usually do not see hydrangeas start opening flower buds until very early April but this year, in the middle of January, I had roses blooming so go figure! My paniculatas and oakleaf hydrangeas are leafing out but as of last weekend, I had not seen any broccoli in them; the paniculatas will wait until May to open the flower buds but the oakleafs may do that soon the way things are going thanks to El Nino.
I have a grocery store hydrangea too and it has not bloomed well. Winter weather messed it up. I planted it in a protected location but the weather was so bad (temps going down then up and all over) that it did not bloom the last two Springs. I guess the flower buds got zapped when it broke dormancy and the temps went down below freezing. This winter, it never lost its leaves since it did not go dormant so maybe it will bloom.
Wish you good bloomage with yours!
