I followed your instructions for propagating wisteria cuttings, but within two weeks they were covered with a white fuzzy mold and all died. Since I have already thrown out the dead cuttings, I cannot send you a picture. However, I have attached a picture of a new set of cuttings that I handled the same way. What should I do to help them survive until they have developed roots?
The first group probably had too much moisture. This time, make sure the soil mix is dry before watering and only water enough to moisten the soil. Do not saturate. Also allow the water to drain off before putting the plastic back on.
I would not let the cuttings touch. You can start another pot so you can separate these.
Here is probably the article you reference:

Hello - I have been trying to look after my wisteria and watering it regularly but it looks floppy, has brown leaves and looks generally unhealthy. Is it infected? I have attached an image. Thank you, Mark
They are drought tolerant plants and don't need a lot of water. I would cut back on the watering if it's an established plant. Brown edges on leaves mean the plant is stressed. Another possibility is the soil is not well draining and the roots are saturated or damaged and can't take up water. If the plant is headed for root rot you may need to move it to a dryer location.
The article below addresses those concerns:

In June I pruned the plant which is about eight years old and had the most blooms ever. But after blooms finished new leaves have wilted and the plant seems to be dead. I have watered it regularly. Could a cold wind have scorched it, as we live on the coast and do get strong winds at times. But plant has never reacted in this way before.
It is possible, if it is cold at this time. After pruning, they can be a bit sensitive. Overwatering will not be good for it though. Only water if the soil is dry down to about 5 inches or so or when it has not rained for weeks. They are somewhat drought tolerant. Overwatering will cause infection.
It will be best to wait until spring to take action, as then you will know whether it is actually injured or if it just needed to recover from the pruning.

Question: In the winter (February) when I further cut my wisteria shoots down to 3 buds... am I cutting the original summer shoot down to 3 buds removing the new shoot sprung from bud 6 or am I cutting the new shoot that spring from bud 6 down to 3 buds leavin g the original 6 bud shoot and a new shoot pruned down to 3 buds?
Growth is numbered by years that it has been alive. Usually, Wisteria blooms on the previous year's growth. Growth from this year will not bloom, but that same growth will bloom the next year.
When pruning, make sure to leave enough of the previous year's growth intact. This will be where the flowering will occur.

I have had mature wisteria 6 years (growing in pot ) and it has flowered this year. From what I am reading ,is this incorrect way to grow it? Regards Gerald
You can, certainly, grow them in containers! Flowering is a good sign that they are happy and comfortable.

Should my wisteria come up from roots each spring?
Yes, in colder regions the top growth will die back in the winter on young wisteria, and in the spring, the roots will send up new shoots. As the wisteria ages and the stalks thicken, there is less winter damange.
The roots can be aggressive. Here's a helpful article about the roots: https://www.gardeningknowhow.com/ornamental/vines/wisteria/wisteria-root-system.htm
If your plant is sprouting too much and you need to get it under control, this article will help: https://www.gardeningknowhow.com/ornamental/vines/wisteria/controlling-or-getting-rid-of-wisteria.htm
I root pruned the plant last year and this year the larger roots stubs that remained in the ground have sprouted aggressive suckers. Today I dug out what I could of these down to about 12" depth and treated the stubs with gyophosphate. Hopefully that solves that issue on last year's severed roots The plant is over 10 years old and the branches are pruned several times a year and we enjoy our multitude of blooms. The issue is the root crown and shallow root stubs put out many suckers and pruning at ground level is hard on my knees and pruners. I blasted the crown with water - that helped to remove the suckers at the root. I am reluctant to remove all of the large roots that move out about 1" below ground level. Which leads to my question: What can I do to slow down the proliferation of shoots?
Pruning wisteria only encourages these shoots, and yet, it should be pruned regularly!
These vines are innately aggressive, especially if they're healthy. This article may be of some help:
