I think my wisteria is dying
So I think I'm killing my wisteria...
It's a small little thing that started out as a bare root and so is planted in a container for now. It has plenty of leaves and was looking great up until last week when I noticed a portion of it starting to die off--leaves turning crunchy and attached stem dying also. I have been giving it a gallon of water about once a week, and I'm now suspecting that I've been overwatering it :( Rookie mistake I guess...but how do I fix it!? I also added about a capful of foliage pro to the water since that's what I do for my other woody plants in containers...was that a bad idea?
Also, I noticed the leaves have a sort of spiderweb-like substance all over them with tiny beige bugs caught up in it. The leaves also look dusty in a way, so I'm wondering if there's some sort of mildew on them? What can I do to save this??
