Step by step: plant tulip
Plant tulip bulbs between October and November, when the soil has cooled but before the first hard frosts arrive. This timing allows the bulbs to establish roots before winter without triggering premature top growth. Choose a site in full sun or partial shade; tulips flower best with at least six hours of direct light, though they tolerate dappled shade under deciduous trees that leaf out after flowering. Tulips thrive in well-drained loam, sandy soil, or chalky soil. Heavy clay must be improved with grit or coarse sand to prevent waterlogging, which causes bulb rot. Dig the planting area to a spade's depth, removing weeds and breaking up compacted soil. If drainage is poor, consider planting in raised beds or mounding the soil slightly. Plant bulbs pointed end up at a depth of roughly three times their height—typically 15–20 cm deep for large bulbs, measured from the base of the bulb to the soil surface. Space bulbs 15 cm apart for a natural look, or closer (10 cm) for dense blocks of colour in formal displays. You can plant in individual holes using a bulb planter or dig out a larger trench for groups. After planting, firm the soil gently and water in if conditions are dry, though autumn rain usually provides enough moisture. Avoid overwatering; tulips need moderate water and dislike sitting in wet soil. Apply a 5 cm layer of well-rotted compost or leaf mould as mulch to suppress weeds and insulate the bulbs through winter. No staking is needed for most varieties unless you're growing very tall cultivars in exposed, windy sites.
