I have two potted wisteria vines that are growing nicely. They have been in pots for about 3 months now. They are getting spots all over the leaves and I don’t know what is happening. I have a water sensor and I was letting the roots get dry before watering and then would do a deep soak. A few weeks ago I switched to only letting the roots get to damp before doing the root soak. Nothing has made a difference with the leaves. Please help! There aren’t signs of aphids on them. They both get about 8-10 hours of full sun. It’s summer now and ranges between 85-95 degrees but that just started this past week or so. It was mild spring temps before then.
