im getting white leaves on my Nikko Blue's and on my Jackmanii Clematis plants. they're within several feet of each other on the north side of a fence. I don't recall having this problem last year. or, if I did, it was VERY minor. this year however the Jackmanii is being consumed from the bottom up by all white (with a VERY slight hint of yellow), leaves that eventually drop off. my Hydrangea has many all white leaves on the inner portion of the shrub as well. again, dropping quickly. I can find anything and everything about "yellow leaves with green veins", indicating (chlorosis), soil PH problems limiting the plants ability to uptake Iron, but I can find NOTHING on all white leaves. one so called "expert" said he had never heard of such a thing! ha! thoughts?
