Wisteria Trim ???

japusJanuary 13, 2013

I am thinking I made a big mistake last year when I trimmed my 4 wisteria vines.
I lopped off the main stem, which now I know I shouldn't have done.
I now understand how to trim a wisteria, however the question I have is...
(((.Once the main stem is cut off..will the last bud on that main stem take over as it's main stem ?)))
I have read a wisteria vine is hardy and hope that's the case here.

Do you have a pic? How old are they?

What kind of wisteria is it - Chinese, Japanese, or American? If it is Chinese or Japanese, was it a grafted plant and, if so, did you cut it off below the graft union? (That's not a good thing to do as what will grow back is from the rootstock which is usually an inferior plant grown from seed and is often a Japanese wisteria, even if the purchased plant was a Chinese one...)

Personally, I think much of the pruning advice for wisterias is unnecessarily complicated! I cut all new whippy growth back into the desired framework once it gets to be 2-3' or so long. I grow both the Chinese and Japanese wisterias to be 'trees' which allows them to be grown as free-standing (except for metal support poles on either side of the trunk) and makes them easier to control. Both bloomed in their 5th year in the garden and the Chinese one started producing the secondary summer flush of flowers in its second year. After cutting new growth back, a flower forms near the pruning site a week or so later! Prune, prune, prune seems to be the rule to get a dense, vigorous plant. I wouldn't grow one on a tall arbour or pergola because it would be too hard to prune it up there!

I love my wisterias and am already looking forward to their spring bloom. Watching the progress of their buds into flower is a measure of the days of spring here :-)

I only grow the American Wisteria (Wisteria frutescens), and I don't think you can hurt it by pruning. It may not be the right time to prune, and you may lose a year's flowers by pruning now, but it is unlikely to die.

This is all Chinese Wisteria, purchased 4-5 years ago from a local Lowes store.
Your looking at the growth before I trimmed it back.
Regarding pruning, I have read in my zone 5. winter pruning in Dec, then summer pruning after flowers...
These were planted from a commercial flower pot
I love these wisteria plants, along with all that I see.
