After blooms have faded, it’s ok to deadhead, but allow the leaves to die off naturally. The leaves are necessary to feed the bulb so it can survive the winter and grow new flowers next year.
Some gardeners think that tulips do not flower well in the second and following seasons so discard them after flowering.
Slow to flower from seed and may not cone true. Best from bulb off sets harvested after foliage dies back in the late summer.
Look to ensure a distance 3.9 inches (10.0 cm) between seeds when sowing - bury at a depth of at least 3.9 inches (10.0 cm) deep.Plant bulbs in autumn to mid winter for flowering the following spring.
