How it works

  • Bulb Mix provides the ideal moisture and nutrient environment for healthy, strong plants
  • It has boosted levels of calcium and magnesium to promote strong growth, lush green leaves and vibrant coloured flowers

How to use

In pots

  1. Use Bulb Mix straight from the bag - don't mix it with other materials. Close the bag tightly after use
  2. Choose a clean container with large drainage holes that is at least 15cm deep to allow for good root growth.
  3. Partly fill the pot with Bulb Mix
  4. Set your bulbs in place at the depths recommended on the bulb packaging or labels.
  5. In pots, bulbs may be placed closer together than the spacing suggested for bulbs in the garden - this will create a denser more showy effect when bulbs are in bloom.
  6. Fill in with Bulb Mix to within 2-3 cm of the rim.
  7. Tap the new pot or container gently on the bench to help the new mix settle in and around the roots. Firm lightly
  8. Water well, allowing excess to drain freely, and keep the pot in a cool shady place until growth shoots emerge. Then move it into a well lit, sheltered position.
  9. Keep the soil moist at all times but do not over-water.


In the garden

  1. Prepare shallow trenches or planting holes slightly deeper than the recommended planting depth for your bulbs.
  2. Line the base of each trench or hole with 2-3cm of Bulb Mix.
  3. Set bulbs out at the spacing recommended on the labels, then cover over with Bulb Mix to the original soil level
  4. Water thoroughly to settle the mix but then don't water again until after shoots have emerged through the soil (rainfall should keep soil moist).
