Just a plain ole compost works well, really big pot they have huge root systems but they are grown as Bonsai too.Place your wisteria container in a full sun location for maximum blooms. You’ll need to check it regularly to make sure the potting soil doesn’t dry out. You’ll need to feed your wisteria in spring every year. Use a general-purpose fertilizer with a ratio such as 5-10-5.

  Thanks Lynn, Sorry I am not familiar with 5-10-5 ratio. I usually use Miracle grow, or Epson salts mixed 1tbs in 1gal water for my plants. It seems to work really well in
  getting them to bloom, just not sure if Wisteria tolerate the Mag. which of course is what the epson salts mix is.

  These three numbers represent the primary nutrients (nitrogen(N) - phosphorus(P) - potassium(K)). This label, known as the fertilizer grade, is a national standard. A bag of 10-10-10 fertilizer contains 10 percent nitrogen, 10 percent phosphate and 10 percent potash. Epsom salt is not recommended for constant use Epsom salt is not an all-purpose fertilizer. It will create healthier, greener, bushier houseplants but only if your houseplants are deficient in magnesium or sulfate. If your houseplants are not showing the yellowing symptoms of a deficiency, Epsom salts may not be beneficial. measure the height of the houseplant in feet. You need a teaspoon of Epsom salt for each foot.Finally, avoid ingesting the salt and keep it out of the reach of children and pets. While generally considered safe, Epsom salts may cause diarrhea if consumed.

  Most soil amendments and fertilizer feeding should take place in the spring. When first planting wisteria, lightly fertilize about four to six weeks after planting in spring or summer. In following years, when the wisteria is well-established, fertilize in early spring and again in midsummer.The first is too add phosphorus to the soil. This is done by applying a phosphate fertilizer. Phosphorus encourages wisteria blossoms and helps to balance out thenitrogen. The other way to reduce the amount of nitrogen a wisteria plant is getting is to root prune the plant.

if you decide to plant it in the ground, it can and will become a fast growing nusicene - I planted two bare root ones about 28 yrs ago and they took over our trees and they keep sprouting up new shoots everywhere

  No Cheryl, This one will stay in a very large pot and I will be more easily able to train it. Thanks for your answer.

  Thanks so much, I just planted my wisteria and as it has been watered thoroughly already I just loosened all the roots that were winding around and planted it using river rocks and newspaper in the bottom which is a suggestion I got from here for all my plants so they could drain without roots not being able to dry out. Glad I was told on here not to fertilize them yet and will wait probably until the end of March when it is super set in its new pot. Because I didn't remove any of the dirt from the ball of it only loosened the roots I hope it hasn't been too traumatized. I'll do as K. below said when I see new growth on the branches. Penne

I use B12 (for plants - in the garden centers) when I transplant. Do not fertilize until you see new growth. You want the plant to focus on a healthy root ball and if you fertilize too soon it grows and bloom with a root ball that cant support it well.
