Silver Lace Vine problem (pic)
Just wondering what could be causing this problem on the leaves of my Silver Lace Vine. When emerging this spring, everything was fine. About two weeks ago, I noticed some discoloration of the leaves, going from green to a brown. Then came some 'blotches' of tan brown.
Our weather has been quite wet this year, but no PM on any other plants, just the usual bottom leaves turning yellow on a few plants in the gardens.
Should I be looking for a pest? (Haven't seen any, but that doesn't mean they are not there...) Or is this some fungal/bacterial problem?
Thanks for any help. The problem is climbing as fast as the vine. I would prefer an organic solution if there exists one.
