I need to detatch my hydrangea petiolaris tfrom the wallo have the house painted. Will it re attach to the wall?

I’m afraid I can’t answer your question but if you have to paint the wall it’s worth a try. I suspect removing it will cause quite a bit of damage so it may be slow or unable to reattach. Maybe a greater chance if it is fairly young and not too big. I wouldn’t have thought you could do it repeatedly, as it would probably check and stall the growth each time. Having said that, if it does reattach and grow you will have a bigger and heavier plant to deal with each time you want to refresh the paint.

If you want to keep the wall painted, I would suggest avoiding climbers or having ones attached to wires which you can release and then lay the plant gently down when repainting ( ensure they are ones with flexible stems as rigid would be more vulnerable to breaking)

You'll have to cut it right back, and then guide it back in to re attach, so it'll take a few years to cover the wall again.
They don't work so well with a support - wires/trellis etc, as they don't grow the same way as things like clematis, and ultimately they reach a huge size, so they need something to root onto. It isn't really possible to have a support covering an entire house wall unless you're keeping it pruned to a smaller size every year, and limiting the spread/height.

In my experience the older stems will not grow any new adventitious roots that are needed to enable it to cling to the wall, it’s only young growth that does that as it grows … so no … it won’t reattach.

As @Fairygirl has said, you’ll have to cut it hard back so that it grows up the wall again from the base.

Can you paint around it?

I think Dove has it.

Cut it down and it will regrow and reroot quite quickly. It will leave root marks and bits of root that will not keep repainted easily. It may also pull away the ols paint and surface.

Maybe there's a decision: climber or paint.

@stevenson999 I have cut one down when it was huge and large parts fell off the wall it did take some time to regrow. Two years maybe.

Iv'e also rescued one that was starting to fall, with the aid of two step ladders and wire which was used to hold it back. It did reshoot at the top and started to fix to the wall at the top. After a year it had completely refixed and the wires were hidden. I think it depends on just how big it is as to whether this will work. You also need to drill the wall which you might not want to do especially as you are trying to repaint.

An idea, cut the hydrangea right back to just the main framework. Paint that and the wall. Allow to regrow. You might miss half a year's leaf and a year's flower, depending on the timing. You might also miss a season's nesting.
