A specially formulated potting mix for growing all types of bulbous plants, like daffodils, tulips, jonquils and hyacinths, in pots or the garden. It includes Scotts Osmocote Controlled Release Fertiliser, which distributes nutrients and feeds for up to 6 months.

When to use


  • Calcium promotes strong flower stems and prevents bulb losses from diseases and rots
  • Includes magnesium for healthy, darker green leaves
  • Includes Coir, a sustainable resource that improves moisture retention while still allowing excess to drain away freely
  • Wetting agent assists moisture to soak into the potting mix and helps roots absorb nutrients
  • Certified to meet the Australian Standard for Premium potting mixes



  • All bulbs in pots, and in the garden
  • Safe to use for new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots



  • Don't use in hydroponic growing systems, ponds or submerged pots (unless covered with a layer of gravel or coarse washed river sand)
  • Don't use on lawns - use only specifically named lawn topdress soils on grassed areas


In pots

  1. Use Bulb Potting Mix straight from the bag - no further additives required
  2. Select a clean pot with large drainage holes (at least 15mm deep to allow for good root growth) and partly fill it with new potting mix
  3. Set your bulbs in place at the recommended depths on the bulb packaging. In pots, bulbs may be placed closer together than the spacing suggestion for bulbs in the garden - this will create a denser, more showy effect when the bulbs are in bloom
  4. Fill in the pot with new potting mix - leave a 2-3 cm below the rim
  5. Gently tap the pot down to help the new potting mix settle in and around the roots. Do not pack the potting mix down
  6. Thoroughly water the bulbs and allow it to drain freely. If necessary, top the potting mix up again to the suggested level of 2-3cm below the rim
  7. Keep the pot in a cool shady spot until shoots emerge. Then move it into a well lit and sheltered position


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 roughly 2-3cm of new potting mix
  3. Set bulbs out according to the spacing recommended on the bulb labels. Then cover over bulbs with the potting mix - enough to reach the original soil level
  4. Thoroughly water to settle the potting mix - do not water again until after shoots have emerged (rainfall should keep the soil moist enough)

    Bulb Mix can be used at any time of the year; however, the main planting times are:

    • March to May for Spring flowering bulbs
    • August to November for Summer and Autumn flowering bulbs



    • Bulb Premium Potting Mix contains a balanced fertiliser up to 6 months - additional fertiliser may be required in time, depending on plant needs
    • Avoid allowing bulbs to dry out - bulbs should be watered immediately after planting and frequently enough to keep the potting mix moist (not wet)



    CAUTION: This product may cause staining of hard surfaces if wet. Avoid contact with hard surfaces and if contact does occur, sweep off immediately

    When using potting mixes, we recommend the use of garden gloves to protect your hands, and if dusty, wear a particulate mask

    SAFETY FIRST: Read the instructions on the product packaging before use and take particular note of any warnings or cautions on the label

    See the Safety Data Sheet for this product



    Coir is a renewable resource used as an environment-friendly and sustainable alternative to peat

    The professional-grade wetting agent included ensures water soaks in readily and aids roots in absorbing nutrients
