Q.potted wisteria plant
Have potted wisteria in a reasonably large pot (4 years). Had amazing flowers this year. New growth appears crumpled…leaves upright and not completely opened, and not new runners. Have not put manure to plant yet…not sure what to add here.
First make sure you don't have a bug problem - distorted leaves are often caused by aphids or scale. After that turn your attention to cultural matters. If manure - well composted, I hope - is your preferred fertilizer, you might add some bonemeal to improve the phosphorous content.
