I went to buy a birthday present for Janice and couldn’t resist buying one for home too. I bought a Japanese Wisteria from Webbs of Wollaston. They were £9.99 each and look really healthy. Now, one month on, it’s still in its original pot and I am nervous about potting it on. I don’t want to lose it. Wisteria is a vigorous climber with long, fragrant, pendulous pea shaped flowers and lime green foliage. This white variety of Japanese Wisteria can grow to 12 metres high and up to 8 metres wide and needs a wall or an arch or pergola. This climber can also be trained to grow up into a mature tree. I have read that the stems get large and gnarled and woody as the wisteria matures. The fragrant flowers appear in spring and early summer and will occasionally give a second flush in late summer.
I don’t really have a perfect spot for this plant so I think I may put it into a large 50 litre pot with a strong support for a couple of years. Update – The Wisteria is now in a large planter with an obelisk for support. Fingers crossed.
New wisteria. Cut the vine back severely right after planting. Then, the next year, cut the main stem or stems back to 3 feet of the previous season’s growth. Once the framework is full size, shorten further extension growth in midsummer to where growth began for that season.
Read that last tip today. 17th April 2018, one year on from planting. It looks a bit scary to cut back like that. The plant still looks ok. New buds showing so I will wait and see if we get any flowers this year.
