FrasstGrow is composed entirely of the droppings of mealworm larvae — what's known as insect frass. Nothing else is added.
Our mealworms are raised on wheat bran. What they leave behind is a premium-grade, nutrient-dense soil enhancer, grainy and dry to handle.
Odour-free, which is the practical reason indoor plant owners choose it over cow manure or vermicompost. You can use it on a balcony or in a living room without the smell.
Packed with beneficial microorganisms and natural plant growth catalysts that improve conditions in the root zone.
Contains chitin — from the larvae's own moulted shells — which acts as a natural activator of a plant's immune response, helping it defend itself.
Boosts and prolongs the fertility of potting mix by adding long-lasting primary nutrients in a form plants can take up readily.
A dry granular powder, so it's easy to measure, store and apply with no mess.
Suitable for: all indoor and outdoor plants — potted ornamentals, herbs, vegetables, flowering plants, coco-coir growing media and garden beds.
Available direct from us and on Amazon.
One scoop per week for a 5-litre pot. Scale up or down with pot size.
Mix — work the frass lightly into the top layer of soil or coco mix.
Water — water as you normally would, so the nutrients reach the root zone.
Sit back — results build over a few weeks rather than overnight.
For new plantings, mix a small quantity into the potting mix before planting.
For garden beds, scatter evenly over the soil surface and water in.
Safe for weekly use through the growing season. More is not better — stay to the recommended dose.
What exactly is insect frass? It's the droppings of insect larvae — in our case, mealworms raised on wheat bran. It functions as a natural organic fertiliser and soil conditioner, in much the same way vermicompost does, but drier and without the odour.
Does it smell? No. This is the main reason indoor plant owners choose it. Unlike cow manure or wet compost, FrasstGrow is dry, grainy and odour-free, so it's usable on balcony and indoor plants.
How is it different from vermicompost or cow manure? It's dry and odourless, far easier to measure and store, and it contains chitin — which manure and vermicompost don't. Chitin acts as a natural activator of a plant's own immune response.
What does chitin actually do? Chitin is what insect shells are made of. When it's present in the soil, plants recognise it and activate their natural defence responses — a plant that has encountered chitin tends to be better prepared against pests and disease.
How much do I use, and how often? One scoop per week for a 5-litre pot, scaled to your pot size. Mix it into the top layer of soil and water as usual.
Can I use it on all my plants? Yes — indoor and outdoor, ornamentals, herbs, vegetables and flowering plants, in soil or coco-coir. It's a general-purpose organic fertiliser.
Is it safe around pets and children? It's a natural organic product with no synthetic chemicals. As with any fertiliser, store it sealed and out of reach, and keep pets from eating it directly.
When will I see results? Over a few weeks rather than days. Typically you'll notice new leaf growth and stronger colour first; root and flowering improvements follow over the season.
Which pack should I buy? 250g suits a few indoor pots. 400g covers a balcony garden. 900g is the better value for a larger collection or a garden bed.
