I used Miracle Gro Moisture Control Organic Soil (I bought a big bag at Costco and used it for other plants, so it is what I had here). The pot does have some drainage holes on the sides and drains out into a saucer shapped edge. I rarely (if ever) water it to the point where water comes out of the drainage spots though. When I repotted the plant the soil was very moist. The roots didn't look alarming, but to be honest, I don't exactly know what I am looking for. I have been encouraged to see some small new growth on it, but want to be sure I'm doing the right thing to let that new growth have a chance. I also don't want to throw away a viable plant, but if there is no hope, I will move on.

I think it's 1920s-30s, definitely with Jacobean influences in those fat legs but probably all kinds of influences. I know they aren't super trendy right now but I love these cabinets and yours has really nice details. Will you be able to glue the wood doodads back together after replacing the glass? Unless it's marked or you get randomly lucky and find a catalog, it will be hard to learn the manufacturer of it. Good score!

It looks to me like some sort of fungal leaf spot - which is usually not fatal or extremely damaging, just unattractive and annoying :-) Keep the vines well pruned to ensure good air circulation and prevent creating a moist environment that would suit fungus. Also clean up any fallen leaves and remove affected ones. Be cautious with watering and mulching to avoid creating a damp environment that might promote fungal growth. It would indeed be useful to know where you are to know more about the environmental conditions they are growing in. Is there a local garden growing them without problems so you have somewhere to compare your conditions to/someone local to discuss the growing process with? What kind of wisterias are they? It's hard to tell from the pictures but it looks like they might be twining counterclockwise which could mean either Chinese or American wisteria....

Any ideas as to these colors? Looks like 2 different ones and I love them both. We have the same shakes on the top.
