Decide how many aubretia plants you want in your garden and remove the rest, Give a few to friends who want them.

They shouldn’t die after flowering. Do you have any well drained sunny positions such as stone walls? They like sharp drainage and they like to hang. I think they’d do better than in pots. I’d spread them around your garden and give away the excess. Be aware they may not turn out to be the same colour as the parent.

@floral_uk z.8/9 SW UK The soil is specifically made for them, well drained and with enough smooth gravel stones, PH appropriate. I am not sure why I see yellow leaves now... They get a lot of sun.

Could they be getting too much water? And the container is plastic so it's not able to breath. It's hard to tell from the picture but the soil actually looks a bit claggy. They want grit rather than smooth stones.

@floral_uk z.8/9 SW UK Grit is exactly what they have, the container has a lot of holes on the bottom so I think breathing and drainage is fine. Maybe the rain is messing with the amount of water they get...
