Three weeks ago I asked about early pruning, and was advised not to do
it yet.

During the weekend I went off and did it. I noticed last night that
white residue is everywhere on the branches of the roses. Is that sap?
It's not powdery mildew, it's more like milk dripping. Was I too late?

Thanks for any answers,
Kostas
