I'm wondering whether its cacti you have or air plants? I've never heard of cacti growing on tree stumps - have you a photo please?

when i read this I thought it was a joke? A MOVEABLE tree stump and CACTI on it ?????presuming this is a serious message, do you mean an old dead tree stump? try googling cacti that grow outside in Britain?You could grow ivy all over it?

Yes I mean an old dead tree stump. I have very gently removed some of the cacti leaves dipped them in rooting powder and put them in a warm place. I then plan to cut out 1 inch square bits of netting and glue them on three sides to the stump allowing a space to push in some cactus loving soil. When my cactus leaves root I'll place them round the stump under the net and then in 20 years , long after i'm dead and gone, there may be a beautiful tree stump like the one i've been given.

well, I do wish you good luck with this Harry, but will they withstand our freezing cold Winters? Could you move them indoors in Winter, say to a greenhouse or conservatory? If it works, post a photo on here in the future?
