I have p. parviflora 'Adcock's Dwarf.' It's been in the ground for about 1 year. It was planted from a 7-10 container last year. Seemed to do fine through the summer and pretty mild winter but then early spring about 75% of the needles turned brown almost overnight and fell off.

There seemed to be no pattern that I could discern to the needle blight. Despite the needle issue, it has been pushing candles all over the place and it seems new growth will come this spring. I am pretty sure this is not fungal blight and I recognize that the process in fact did not start overnight but just seemed to manifest that way.

I have read here and elsewhere that "needle retention issues" are common with Adcock's dwarf.

Does anyone know what that means?

Thanks in advance.
