Plant both now wisehedgecrone. I grow them both in pots and in the borders. Don't worry about the lilies you've already planted, they'll come up soon I'm sure. No need to dig them up and disturb them. Whereabouts in the country are you, perhaps it's just not warm enough for them yet. Some but not all of mine are showing.I grow several different types of them and they're always reliable. Unless the lily beetle gets to them.
I leave the tops of my Nerines exposed and they stay in their pots over winter although I put them somewhere frost free. I grew them in the ground for years and for a few years now they've been in pots. I just use mp compost for both although folk say lilies like ericaceous soil.
