I put some of mine in the soil last sunday. So any time now really. Dig the hole larger than the pot, make sure the soil is losened up in the bottom of the hole. I mix in compost with some of the soil. then I carefully knock the plant out of the pot and place it slightly deeper [bulb 4-6" below the soil level] re place the soil and fir and water well.

hope this helps.

Thanks for that, my lillies started off with about 3 or four in the pot last year, they are still in the same pot this year but their must have more than doubled this year, will i be able to seperate them?

yes you could but you will damage the roots and this may cause them to wilt/fail. I would probably wait until the autumn/spring. I usually tip them out of their pots in autumn and check the bulbs for vineweevils/pests. I then repot them in new compost and separate them then. The smaller bulbs are potted on and kept 'round the back' of the greenhouse until flowering size.

Thankyou Seaburngirl I appreciate your advice I'll leave them for now ,I need to sort my soil out anyway, do you have any tips on soil conditions for them?

They prefer soil that is slightly acidic. I have never personally had any problems with Lillies growing in ordinary compost. I have mine in pots and just leave them over winter.

Thanks Kidermorie I'll try some in pots and some in the garden and see what works better

mine are in slighty alkaline soil as I garden on chalk. I mulch the borders with home-made compost and leaf mould in the autumn.
