| Tulips need to continue to grow their foliage through maturity and then go through the ripening process in order to rebuild their strength to bloom next year. Allow the leaves to grow and then turn brown naturally. Remove them when they are at least half way browned and come off easily in your hand. Remove the spent flowers making sure to take the base of the flower in addition to the petals. This will prevent the bulb from wasting energy trying to set seed. |
