Let the leaves on your tulips dies back completely and whilst they are doing so water once a week with half strength liquid tomato feed, this will put energy into the bulb and help it to form next years flower bud. The tulips in the ground I would leave where they are they will be fine until next year. You could actually leave the ones in the container but I assume you want to use it for something else so once the foliage has died back completely life and hang up in your shed for the summer and plant again in autumn.

Moon grower has given an excellent answer but just to add that with my pots of tulips I just move the pots to the back of the garden and let them die down there in their pots and bring down the pots next year when they are ready to flower. And I must remember to feed them too. Thanks for the reminder.

I fed my new collection of Tulips with this mixture and lost the lot, they grew well, then turned brown. Think the rich compost + feed was too much for them.

Diane I have already told you not to feed until after flowering has finished. You stated previously that you started feeding as soon as first leaves appeared. The rich compost is more likely the culprit though think of where tulips grow in the wild, the soil is lean and thin...

Thank you everybody. What would we do without GoY?
