Remove the flowers and put the pots outside somewhere to allow the foliage to die back naturally, feed with half strength tomato food to give the bulb a good start for next year. Once the foliage has died back plant them in the garden somewhere. They will never be as spectacular as the first year but will continue to flower for many years to come.

Thank you

You're welcome Green

The ones from 3 yrs ago are in full flower in the border where I planted them after the indoor flowering. the blooms as Moongrower says aren't as big but still garden worthy.
