Benefits from adding compost or well-rotted manure
Sunlight Thrives in full sun to partial shade. Minimum 6 hours of direct sunlight daily produces the best flowering results.

Maintain consistent moisture during active growth in spring
Reduce watering as foliage yellows naturally
Avoid overwatering during summer dormancy
Temperature
Requires cold winter period (12-16 weeks below 10°C)

Excellent frost tolerance
Spring Care
Apply balanced fertiliser when shoots emerge
Remove spent flowers to prevent seed formation

Mark planting areas to avoid accidental disturbance
Mulch lightly to suppress weeds
Autumn Preparation
Clear away any remaining dead foliage
Apply compost around planting areas
Check for overcrowded clumps that may need dividing

Poor Flowering Usually caused by insufficient winter chilling, overcrowding, or inadequate sunlight. Ensure proper planting depth and consider relocating to sunnier positions.
Bulb Rot Typically results from poor drainage. Improve soil structure with organic matter and ensure planting sites don't collect water.
Short Flowering Period Normal for tulips, but can be extended by choosing varieties with different bloom times and providing consistent spring moisture.
Buy firm, plump bulbs without soft spots or mould
Larger bulbs (12cm+ circumference) produce bigger flowers
Purchase from reputable suppliers for guaranteed variety authenticity
Plant immediately upon purchase for best results
With proper planting and care, Tulip Columbus will reward you with magnificent spring displays for 3-5 years minimum.
