To prevent tulips from drooping in the vase add a copper coin - eg 1p - to the water

My mother always makes a small pin prick just below the head if the flower if they are cut in a vase and that generally works. If they are in the garden try green garden canes.and loose string.

take them out and wrap them in paper as a florist would. trim the ends, refresh the water and after a couple of hours all shoudl be well!
