Arrival of Bulbs

Tulip bulbs are supplied in their dormant state and should remain dry and cool until planting. If you are unable to plant immediately, store the bulbs in a cool, dry location with good air circulation.

  • Keep bulbs dry at all times.
  • Store away from direct sunlight and moisture.
  • Ensure the storage area is well ventilated until planting.
  • Plant within 4-6 weeks to ensure best growing performance.

Planting

  • Plant tulip bulbs during autumn, ideally between October and November, once the first frosts have occurred. Cooler soil temperatures encourage healthy root establishment while helping to reduce the likelihood of soil-borne diseases.
  • Tulips are suitable for growing outdoors or under protection, including garden borders, raised beds, containers and growing crates.
  • Choose a site that receives full sun or light shade.
  • Position bulbs so they are covered by approximately 12cm of soil, resulting in an overall planting depth of around 20cm.
  • Place each bulb with the growing tip pointing upwards.
  • Leave approximately 8cm between bulbs to allow adequate growing space.
  • Where soils are heavy or prone to holding water, improve drainage by incorporating coarse grit or sharp sand before planting.
  • When planting in containers, use a high-quality free-draining compost and ensure excess water can drain freely through the base.

     
For a longer flowering display in containers, Bulbs can be planted in layers, positioning the later flowering, larger bulbs at the bottom and earlier flowering varieties nearer the surface. Separate each layer with a covering of compost before adding the next.

  • Water thoroughly after planting so the compost or soil settles evenly around the bulbs.
  • In colder regions, bulbs grown outdoors benefit from additional insulation during winter.
  • Raised beds should be protected around both the top and sides, helping to minimise frost penetration and protect developing bulbs.

Watering

  • Maintain consistent soil moisture while plants are actively growing.
  • Tulips perform best when supplied with generous amounts of water during their growing period, particularly where bulbs are being forced.
  • Ensure soil remains moist but never saturated, as prolonged waterlogging can affect bulb health.

Additional tips

  • Layering bulbs in containers is an excellent way to produce a fuller, longer-lasting spring display.
  • Remove faded blooms once flowering has finished to prevent unnecessary energy expenditure.
  • Leave the foliage untouched until it has naturally yellowed and withered, allowing nutrients to return to the bulb for next year's growth.
  • Once plants have entered dormancy, bulbs may be lifted, cleaned and stored in a cool, dry, airy environment until the following autumn.
  • Applying a balanced slow-release fertiliser during early spring can help maintain healthy growth and improve future flowering performance.

Grower FAQs

Many modern tulip varieties naturally flower most strongly in their first season. Allowing the foliage to mature fully before removing it helps replenish the bulb's energy reserves. Lifting and storing bulbs correctly during dormancy can also improve future performance.

Tulips dislike sitting in wet ground for extended periods. Improving drainage with coarse grit or growing in raised beds or containers filled with a free-draining growing medium will create more favourable conditions for healthy root development.

Where winters are particularly severe, insulating raised beds helps protect bulbs from freezing temperatures. Providing protection around the sides as well as over the surface offers better overall insulation.

After planting, water thoroughly to settle the soil. Throughout the growing season, keep the soil evenly moist, especially during periods of active growth, while ensuring excess water drains away freely.
