I'm really thinking about taking it out and replacing it with something that is less work, but then I'd have to spend hours sawing at the thing to get it off of that tall trellis. I just have a hard time making myself spend that many hours on something that doesn't make me food...
Any suggestions? We're in zone 7B.
imo wisteria tends to destroy things unknowingly. it thinks its doing great and it is, but its also choking out other trees, wrapping around posts squeezing them to the breaking point, finding its way in tiny cracks in your house.
the only wisterias i have seen that i liked were out in the open and trained into small trees. 10x easier to prune and control if you have to have that wisteria fix.
The world's largest known Wisteria vine is in Sierra Madre, California, measuring more than 1 acre (0.40 ha) in size and weighing 250 tons.
If it makes you feel any better, wisteria is a nitrogen fixer. Whether or not the fixed nitrogen is a benefit relative to the maintenance required to keep the plant in check is a tough call; however, just think, all the pruning you do to the plant releases that much more nitrogen into the soil.
It's awesome for attracting bees, and other pollinators as well.
i believe if you cut the wisteria back and replace it with an aggressive climber... and also as it is coming back.. if you are vigilant about cutting it back ... it will be less and less until it is no more
the key is to have a fast growing species to replace the wisteria that will do well with that added nitrogen.... cut it back... shade it out!
I can see the root system is expanding but the way I see it, I'm simply getting more and more organic matter into my soil, and more nitrogen fixing. Someday those roots will be dead and decomposing down there. Thats a great thing right?
So as long as its in zone one where I can keep chopping and dropping, I can't think of a better nitrogen fixer for the garden simply because it produces so much nitrogen rich biomass. Out in a zone 3 or 4 I would discourage it because it would probably spread out and take over everything... in 20 years you would have a wisteria forest... REALLY SUCH A BAD THING? But as for a zone 1 veggie garden I say YES grow that! In the ground or in a container your choice... I prefer in the ground where they put roots down and feed the soil from below as well as on top.. it produces so much biomass.
Also it's so trainable you could probably make living furniture out of it... or head pieces.. it's useful! I see it as a blessing not a curse. I think a lot of people who see this the way I do will appreciate this plant and I am propagating them from seed and cutting to offer for sale in my little backyard nursery.
So in conclusion, I think it's a great chop and drop biomass producer and nitrogen fixer. High maintenance tho so keep it in zone 1 or 2, maybe contained...
I have a wisteria that I planted directly between my back door and the gate to exit the property so I can keep an eye on it and chop and drop it as needed. It is also surrounded by a new garden bed that needs nitrogen, so the arrangement is pretty nice, and there is nothing for it to climb that will complicate the work pruning it.
A lot of good can come from wisteria
-vigorous grower = biomass plant
-nitrogen fixer = fertility plant
-nice scent and color = sensory plant
-great bee plant = pollinator plant
sounds like with proper planning and placement it could be an asset to any permaculture system. I have quite a few stumps around my garden that function as pumps, as soon as green growth appears I will pull it off and mulch the surrounding plants.
mulberry, trumpet vine, Virginia creeper, and hackberry all grow so quickly that they put a lot of organic material onto the soil without any extra inputs. They will be a huge asset when a drought comes my way.
