Frankly, I can't see that working - rotary lines, as I'm sure you know, fit into a socket which is inserted beneath the soil and cemented into place in order to bear the weight of washing blowing about on a windy day. Any pot you try to do that in will just fall over. Not to mention that any planting underneath or within 8 feet of a rotary airer would need to be very low growing, otherwise things like sheets, etc., will be dragging across the top of plants. That's usually why they're in lawns or at the edge of patios, because of the open and clear space around them.

I think you can buy rotary washing lines that fit onto the wall of the house

I wasn't really thinking of a pot, more like a wooden planter. She doesn't get a whole lot of washing being as she's alone and as it's quite a big rotary line she feels sure that the sheets etc wouldn't drag in it as long as they hang on the outer lines. I'm not talking anything huge here... I'm thinking about 24" x 24" or something around that size. Would it be possible to set the pole in concrete inside the planter and then fill with compost?

hi Dioritt, I have my line surrounded by wooden planter,I put a scaffolding pole through bottom of container and hammered it into ground beneath then rotary line fits into pole. It works great. If you go to my pictures, photo 1 and 10 of 310 you can see what it looks like. I also now have a border between the grass and path and as long as you keep fairly low growing plants at "whirly" end it is fine. good luck

Helen's solution would work, hammering something through into the ground like that - but you won't be able to move the planter afterwards!

Thanks, Helen. That sounds like a really good idea. I'll look into how I can do that. I doubt Mum will want to move the planter anyway so there's no problem with it being a permanent fixture :-)
