Do you care to elaborate as to why this is bad? It the temp change too much of a shock?
Yesterday it was 66F here and honest the grass was mostly green. The plants front and back yards potted or planted have started to push or bud but no sign of leaf emerging. This "to me" is controlled more by length of day then temperature.
Some plants never loose leaf and normally just change leaf color. They also react to temperature but not as one would think is good but really is.
Last night we had a severe drop in temperature accompanied by a fair amount of snow, actually the only real snow we have had here.While shoveling and cleaning up the car and truck I noticed this Rhododendron acting cool, and to me it shows the benefit of snow/ice insulating a plant which honest took me a long time to see and understand as it seems crazy.
I noted the picture to try to better explain;
The Blue circle shows the leaf fully covered in snow but fully open and extended supporting the snow.
The Green circle shows that after I brushed some away for the picture.
The Red circle shows the leafs curled as they are every morning it is 28-32F and normal - they were NEVER covered in snow.
That was at 3PM here and they wide open leafs I uncovered are now fully curled at 5:20PM as the Red circled are. The blue circled left undisturbed are still extended supporting the insulating snow
Hard to explain but snow is your friend and from experience it helps more then harms most plants that are acclimated to your location
No plant was hurt in any way - kind of cool
