We've lived in our four year old home in the Willamette Valley of Oregon for over two years. The pergola over the driveway has a white wisteria on either side, finally beginning to meet in the center. The wistera on the WEST side of the pergola didn't seem to do well, leaf-wise, but was abundant with white flowers and now with strange seed PODs, that are still green, October. What is recommended to fertilize the WEST side to continue to produce flowers? And what can be done with the seed pods? Are they harvestable and replantable? Thanks, Marilyn, relatively new homeowner.
