Uncover gydrangeas- when?
My hydrangeas are covered with leafs, boxes, to overwinter them in zone 5a/b. I hope they are still alive?
When should I uncover them? Temps are fluctuating and quite low for this time from about -2* +4*Celsius, nights are even much lower.
What and when should I do?
Thank you all.
***** don't tell me I have to cover myself first:-)
