Grow Notes

One ingredient. Plenty of growing potential.

Easy to use, low in odour and ready to apply directly to soil. No complicated preparation needed!

How to Use

Three simple steps

1. Sprinkle: Apply the recommended amount evenly over the soil around your plants.
2. Mix: Gently work the frass into the top layer of soil, where practical. Avoid piling it against delicate stems.
3. Water: Water in after applying to help incorporate the frass into the soil.

That's it! No composting or ageing required before ordinary soil application.

Pots & houseplants

For established potted plants, start with the following amounts:

• Small (10–15cm): 1–2 level teaspoons (1.9–3.8g)
• Medium (20–25cm): 1 level Australian tablespoon (7.6g) 
• Large (30cm+): 1–2 level Australian tablespoons (7.6–15.2g)

Garden beds & vegetable patches

Mealworm frass can be used for both maintaining established garden beds and preparing soil before planting. The amount depends on how you're using it:

• Established garden beds: 50g/m² (about ½ cup). Lightly top-dress around established plants.
• Higher-demand garden beds: 50–100g/m² (about ½–1 cup). Apply according to crop needs and existing soil fertility.
• New garden bed preparation: 100–200g/m² (about 1–2 cups). Mix evenly through the upper 5–10cm of soil before planting. 
• Individual new plantings: A modest amount appropriate to the planting. Mix into the surrounding soil rather than concentrating against roots.

Lawns & grass

Rich Roots can also be used as a supplementary organic soil amendment for established lawns and new lawn preparation:

• Established lawns: 10–20g/m² (about 1⅓–2⅔ Australian tablespoons). Distribute thinly and evenly, then water in thoroughly.
• New lawns or seedbeds: Around 30g/m² (about 4 Australian tablespoons). Lightly incorporate into prepared soil before seeding.

How often?

For most established plants, herbs and garden beds, start with feeding every 4 weeks during active growth. Fast-growing vegetables, actively fruiting plants and other nutrient-hungry plants may benefit from feeding every 2–3 weeks if needed. During cooler months, low-light conditions or periods of slow growth, reduce feeding frequency.

Tip: Start with the lighter amount, particularly for indoor plants, seedlings, new transplants and sensitive species. Increase only where plant needs and growing conditions justify it.
