Scotts Osmocote® Professional Seed Raising & Cutting Mix

A superior quality propagating mix for germinating vegetable, herb and flower seeds and for rooting stem, leaf and root cuttings. It includes Scotts Osmocote® that feeds for 3 months

  • Provides the ideal moisture and nutrient environment for improved germination
  • Controlled release plant food provides balanced slow nutrient release over three months that is gentle on young plants
  • Formulated with gypsum and phosphorus for better rooting and vigorous growth
  • Wetting agent added to ensure uniform wetting of mix and prevent drying out
  • Coir creates the ideal moisture and nutrient environment - never too wet or too dry
  • Water crystals keep tender seedling and cutting roots moist

Gypsum & phosphorus

The calcium in gypsum promotes strong growth while the phosphorus encourages better rooting from both seedlings and cuttings

Water crystals

Absorb and hold many times their own weight in water, releasing back into the mix as and when plants need it. Helps keep germinating seedling roots evenly moist


A renewable resource that also aids in moisture and nutrient retention

Australian Standard

Certified to meet the Australian Standard for Premium potting mixes

How it works

  • Provides the ideal moisture and nutrient environment for producing improved germination of seeds and root strike on cuttings
  • Remains moist for longer but never so wet that seeds or cuttings rot

How to use

Sowing seeds

  1. Fill a clean seed tray with Seed Raising & Cutting Mix, level off with your hand, firm lightly and water with a fine, gentle spray
  2. Sow seeds thinly and evenly as per seed packet instructions. Cover the seeds if required with their own depth of mix, pressing lightly to ensure they remain in the mix and will not be washed off
  3. Place the tray in a warm location away from direct sunlight. Keep consistently moist to the touch by periodic misting
  4. After seedlings have formed their second set of new leaves, transplant the new plants into larger pots or outdoor containers using Scotts Osmocote® Professional Premium Plus Potting Mix

Establishing cuttings

  1. Take a cutting in the appropriate way for the type of plant you are propagating
  2. Fill a pot with Seed Raising & Cutting Mix to within 2-3cm of the rim
  3. Using a dibble (about pencil thickness) make a hole in the mix and insert the cutting to about one third its length and firm in place by pinching the mix with your fingers
  4. Several cuttings can usually be placed into the one pot but don't overcrowd them - allow room for root and leaf/shoot growth
  5. Water well and keep the pot in a warm place out of direct sunlight. Enclose the cuttings in a plastic bag or similar held in place around the pot's rim with an elastic band to create a mini greenhouse that will retain humidity
  6. Keep consistently moist - remove the bag and mist the mix if required
  7. After a few weeks, test the cuttings by very gently pulling on them one at a time, Any resistance means roots are forming
  8. When cuttings have developed good roots, report individually or plant out into the garden, depending on the time of year and type of plant being raised
