Last year I dead headed some of my lilies and then planted them from pots into the border and have been rewarded by some lovely flowers this year.

Don't know if this is correct, but it works. See my photo's

Also, I have some that I simply left in their pots and use as patio plants. Hide them away in the back of a border until next spring and bring out to brighten up your patio or terrace areas.

The ones left in their pots are a little later in flowering.

just dead head the flowers but leave the stems to die back naturally, then they can be removed later in autumn.. if you keep them in the pot over winter make sure you keep the bulbs protected as they are more exposed in the pot than they are in the ground..

Thank you, I will give it a go.
