Black eye susan vine - some sort of fungus?

[canesisters]

About a month ago I was at a hardware store and they had hanging backets for $5 - BIG ONES! One of them was a black eye susan vine so I snatched it up and planted it next to my backyard gate. It did well for a couple of weeks but now is turning yellow around the bottom and the yellow leaves are getting black spots. It's putting out new growth. Probably 3" or so of new vine, and LOTS of blooms. Some of the black spots eventually turn into holes, but I don't see any signs of bugs. Some sort of fungus????
Or just transplant stress???
(I know, I know... 'where are the pictures?'... I'll try to get some this evening)

Older leaves may not be of much, or any, value to a plant.

The photosynthesis powerhouses are the newer, fully-opened leaves. The older leaves slip into a non-productive state as they age.

Now, this is what I've learned from horticulturalists. I can't imagine how they could hook a meter on a leaf & determine how much it is producing in the way of sugars & starches. Still, it seems to make sense and you may just want to remove those leaves and allow the plant to continue with its new growth.

Could you be watering it too much? This causes leaves to turn yellow and fall off.

I started some from seed, and ran out of room for them... so they have sat in their tiny pots getting rained on day and night. Mine look exactly as you describe. Bought my Mom two very large plants for mothers day- and they are gorgeous, not a spot on them. Go figure. One of my favorite plants, though!

Didn't get picts... one of those afternoons. :/

It's not that it's getting too much water - but maybe irrigular watering?? It does wilt in the afternoon if I've skipped a day or 2 watering it. It looked really sad yesterday afternoon and thankfully we had some rain overnight. If I get a little bit of time tonight, I think I'm going to put up a little trellis on the fence behind it. Then do some pruning of all the lower leaves and work out some of the tangle at the base. Maybe, since it was a hanging basket when I bought it, it's having trouble with sitting right on the ground??

Hope it makes it - such a pretty little thing.
By the way, does the vine self seed like the 'regular' black eye susan plant? I'd LOVE for this little thing to just take over that whole corner eventually.

I bought one that was potted and planted it in the ground too, but it hasn't done much climbing on it's trellis. :/

As to your question about it reseeding...I don't know... But it is not related even remotely to the perennial black eyed susans.

They are rudbeckia...the annual vine is thunbergia. But now that you mention it I think I'll collect the seeds and see if I can't start them next spring.

I bought seeds. They take forever- so start early!

I have never had them to reseed.
