Formative Training Wisteria

TheSouthernGardener

Hello All,

I've  recently bought a wisteria ' Amythest Falls' from my local garden centre. Supposedly smaller and less vigorous than chinese wisteria apparently and as you can see from the pictures she's about three feet high,flowering lovely and seems to be happy enough in the large pot bought for her. I'm keen to unwind the plant from the little trellis it came wound around but don't really know where to start. My plan is to attach a strong trellis to the wall and run it vertically to about 8 ft.  whereby it can hopefully be trained along a wooden beam running the length of the side of the house. Any hints on achieving this would be great and also should I wait till the flowers have done their thing or crack on right away. Thanks.

I would say to enjoy the flowers now - they don't last very long. The growth will speed up after they have finished. I would imagine she would be happier in the ground, if you can swing it. How much sun does the wall get?

About six to eight hours, I've got clematis and roses on same wall and they flower well even though it's not full sun exposure all day. Much keep it in admittedly very big pot as it's sitting on concrete path. Everything is basically in pots at the side of the house as the previous owner covered it with tarmac 😠

Others will know, but I would say the pot might not be large enough if you want it to rise eight ft and cover a wall. It would be a huge amount of watering also.

I have a wisteria on an east facing wall that gets full sun till midday and then just good light but not direct sun.   I would think 6 to 8 hours are plenty but that pot needs to be a lot bigger to sustain a wisteria and will need regular watering and feeding.

Might be worth seeing if you can remove some of the tarmac to plant the wisteria and roses in the ground.  It's often not that thick a layer but it depends what's underneath - horrendous rubble or some good soil?
