How to Chelsea Chop sedums?

NoSlugsPlease

Hi all. I bought 2 sedums Autumn Joy last year and they've now grown into 2 huge globes. I want to give them the "Chelsea Chop" to keep them from getting too big, but I'm not sure how it should be done on a plant of this shape.
The websites I've looked at show sedums that grow straight(ish) up from the ground. Should I cut all the stems back by 1/3 or some of the stems?
Thanks.

I just did mine yesterday and cut by about half, basically at where the florets were beginning. Mine were not huge. I did the same last year and it worked really well. This year I cut about half my plants, so some will bloom from June and others will start maybe in July and be more sturdy. I take the off cuts and pot them up.

I've done mine quite deep round the edges and left some in the middle.  Some people do it a bit more randomly,I believe. And some chop the lot.

Thank you. Looks like it won't go too wrong whichever way I do it...fingers crossed...

Does anyone CC verbascum? Successfully?

 A long but interesting article on the Chelsea chop says that Verbascums require a gentler approach

Useful. Thanks @AnniD

Sedums can be cut back by around half and will then be sturdier but with smaller flowers.  They can sometimes be a bt slow to put on new growth afterwards so I prefer to trim some stems and not others, to mask the damage.  The longer stems are then held up by the others and you get an extended flowering season.  I haven't tried cutting back Verbascum but I suspect it would not work.
