Thanks rhizo_1! Do you have any specifics in mind? I'm a lot less familiar with annuals than I am with perennials.

We can all make suggestions but not until we know how much sun these plants will receive during the day.

It gets about 5-6 hours of full sun, and partial shade the rest of the way. It's also been raining every 4-5 days, which keeps the soil moist. I'm in Cambridge, MA, so zone 6, I believe.

Plant some annuals if there is room (some dark petunias draping down would be nice, especially if they were scented ones...) but that doesn’t really address the issues.... If the soil is wet in the pot, either the soil mix is not right and holds too much water, OR the drainage holes in the pot are inadequate or plugged, OR you’re watering too much. Figure that issue out and correct it - don’t count on annuals to solve that problem. The other issue that strikes me is that 5-6 hours of full sun is less than optimal for wisteria bloom development - can you move the pot to somewhere that it will get more sun?

What kind of wisteria is it - American, Chinese, or Japanese? It’s not going to stay 1.5’ tall for long! Are you pruning it now to promote flowering wood development? I haven’t grown the American type but do have both a Chinese and a Japanese one. The Chinese one started producing summer flowers in its first year as we pruned it - about 7-10 days after we pruned back whippy new growth, a flower raceme developed near where we had cut it back - so we’re were sure that one was developing flowering wood! It still took 5 years to do its first spring flower show, but we were in no doubt that it eventually would! The Japanese one has never done the summer flowers with pruning. It took 5 years too to do its first spring flowering. Our experience is that prune, prune, prune is the way to get them to flower relatively quickly and profusely (plus keep them under control!) Have you grown wisteria before? Has that been your experience with them too?

Hi woodyoak! Thanks for the advice. Yeah, I realize that I'm guilty of watering even if it's rained recently, so the soil never really dries out. Now that I've realized it however, I figure having 1 or 2 annuals with them in the pot would somewhat help. Also, because I only got these wisteria about 3-ish weeks ago, they just recovered from transfer shock recently, which is why I'm slowly easing them into more sunlight per day. I started with 3, brought it up to 5-6, and maybe in a week or so, i'll put them in a sunnier spot.

As for previously growing Wisteria, I've had the exact same experience, except I started with the American and Kentucky variety, so it was very easy to control. Unfortunately, it ended up having WMV and I had to get rid of them. I've since sanitized and bleached everything, and am starting again from square one, which is why I'm all antsy about these ones (helicopter parent haha).

I was wondering, could you also please provide your input on my other post? I suspect it's edema cause it looks quite different from what I think WMV looks like.

I saw your other post - but I’ve never had to deal with any significant disease issue with mine so I have nothing to contribute :-). If it’s not WMV, I’d think it might likely be something related to the wet soil and perhaps the low hours of sun. Where did you get the wisteria from? I doubt that there is much point in gradually increasing the sun it gets - if they were grown outdoors, they are probably used to - and want - full sun....! As long as it is getting sufficient water - and it sounds like it may be getting too much! - it should be fine in full sun. I’ve never grown them in pots though.... I only grow them in the ground, so I have no direct experience with your growing situation. Any perennials I’ve grown in pots are always put in sun if they are full-sun type plants. They never have problems as long as they get sufficient water for their needs.
