Planting Guide
Planting Depth
Plant 6–8 inches deep, measuring from the base of the bulb.
Planting Time
Plant in autumn after soil temperatures cool below approximately 60°F.
Spacing
Space bulbs 4–6 inches apart for a full display.
Site Selection
Choose a sunny location with fertile, well-drained soil. Avoid areas where water stands during winter.
Planting Tips
Plant bulbs with the pointed end facing upward. Water thoroughly after planting, then allow natural winter moisture to sustain them until spring.
Garden Care
Water Requirements
Moderate during active growth. Once foliage has died back, bulbs prefer relatively dry summer conditions.
Fertilizer
Incorporate compost when planting or apply a balanced bulb fertilizer in autumn and again as shoots emerge in spring.
Maintenance
Remove spent flowers to prevent seed formation while leaving foliage intact until it yellows naturally. This allows energy to return to the bulb for next year's display.
Pests & Diseases
Generally dependable. Bulbs may be damaged by rodents in some gardens. Excellent drainage greatly reduces the risk of bulb rot.
Cut Flower Use
Harvest stems just as the flower begins to show color but before fully opening. Tulips continue to elongate after cutting and develop beautifully indoors. Fresh stems typically last 5–7 days in a vase and pair especially well with alliums, narcissus, peonies, and flowering branches.
Companion Plants
Beautifully combined with:
Allium 'Mount Everest'
Anemone coronaria 'The Bride'
Galanthus woronowii
White foxgloves
White peonies
Phlox 'David'
Campanula 'Alba'
