Tulips are grown from bulbs and have a cool requirement of at least 2 months of soil temperatures less than 9°C

Spacing/Density:

Plant 12–30 cm apart (depending on cultivar and bulb size).
Plant in one metre wide beds and allow 45–60 cm between the rows. If bulb circumference is 8–9cm this equals 1–2 million bulbs/ha. If bulb circumference is 10–11cm this equals apprx 500,000 bulbs/ha

Crop protection:

Shelter is needed from strong winds as this may damage the blooms.

Soil type:

A crumbly soil type is needed that is well drained and has good structure. Irrigation may be necessary if conditions are dry between August and December. pH 5.5–6.5

Fertilisers:

The nutrients required include nitrogen, potassium and phosphate. Best added before planting.

Pest/Diseases:

Tulip virus, Stem and bulb nematodes, Botrytis, Bulb rots, Phytophthora, Fusarium, Thrips

Harvesting:

Flowers should be cut 1–2 days before full bloom stage when 50% of petals show colour. The flowers keep at 0–5°C for about 2 weeks and have a vase life of 4–11 days at 16°C. Flowers are picked in bunches of 5 or 10 depending on the market specification and should be stored in an upright position. To prevent damage, flowers should be packed in sleeves.

Marketing:

Tulips are sold directly to florists or through the auction system. There is also an export market for them. Tulip bulbs can be grown for Northern Hemisphere producers. This is usually done under a contractual arrangement for a particular buyer.
