It is traditional to plant tulips in October when the ground starts to cool down. Tulips do benefit from using bulb starter when first planting and if you can loosen the soil to a depth of 20cms that would also be helpful to the root development. Plant tulip bulbs 15cms deep and 10cms apart in free draining soils. In the heavier soils add grit and rotted humus material to give extra drainage.
Tulips if left in the ground are are unlikely to re-flower after their first year. The alternative to discarding such an expensive bulb is to lift and dry the tulip bulbs after flowering. Deadhead to prevent seed production and wait until foliage turns yellow before lifting the bulbs. Lift and allow the bulbs to dry thoroughly before storing.
Propagation: Division, Separate offsets when bulbs are lifted to be stored dry in a tray over summer. Replant offsets at least 15cms deep rather than too shallow or they may not flower. Feed during flowering and leaf stage.
