A bit scared
I impulse bought some Meconopsis Lingholm plants in 7cm pots early autumn. They were very cheap and I couldn't resist. I can't remember now who I bought them from (online) but had some email discussions with the very helpful seller who thought the position I had for them was ideal, acidic, moist, light shade but said to pot them on and plant them this spring. I know they need moist soil in summer but free draining as well especially in winter. My plan is to dig quite deep holes and put a good few inches of grit at the bottom so they won't get waterlogged in winter. My question is should I use ericaceous compost or a soil based ericaceous/grit mix? I don't want to make it so well drained they're too dry in summer. I'd love to have this plant thrive in my garden and want to give them the best chance, all advice welcome.
