No. 02 — What Flytiliser actually does
This isn’t just
fertiliser.
Most fertilisers feed your plants. Flytiliser feeds your plants and your soil — and it does something no seaweed feed, worm casting, or synthetic granule can replicate. Here’s what happens when you use it.
NPK 3-1-3 delivers meaningful nitrogen for leafy growth, phosphorus for root development, and potassium for stronger stems, better fruit, and improved disease resistance. Not trace amounts — real, working levels that you’ll see in the plant within weeks.
And it’s slow release. Synthetic fertilisers deliver a fast spike and disappear — often washing straight through the soil before the plant can even use it. Flytiliser breaks down steadily over weeks. One application feeds your plot for a full month or more.
Flytiliser is microbially active — it introduces and feeds the beneficial bacteria and fungi that healthy soil depends on. Healthy soil biology means nutrients become more available, water is retained more efficiently, and soil structure improves with every application.
Synthetic feeds can’t do this. Many actively damage the microbiome that makes soil productive in the first place. Use Flytiliser consistently and you build soil that works harder each season — not soil that needs ever-increasing inputs to perform.
Flytiliser contains chitin — the natural biopolymer found in insect exoskeletons. No seaweed feed contains it. No synthetic NPK contains it. Nothing in a garden centre contains it.
When chitin enters the soil, plants interpret it as a signal that insect pests are present and activate their own natural defence systems — thickening cell walls, producing defensive compounds, stimulating mycorrhizal fungi. The result is crops that are measurably more resistant to pest damage and disease, without any chemical input whatsoever. Your plants defend themselves.
Seaweed fertiliser — Maxicrop being the most common — has an NPK of roughly 0.3-0.1-1.5. Flytiliser is 3-1-3. That’s ten times the nitrogen, ten times the phosphorus, and double the potassium. Plus chitin. Plus live microbial activity. Seaweed is a soil conditioner at best. Flytiliser is a genuine plant feed that also conditions the soil.
Over-apply synthetic fertilisers and you burn your plants — roots scorched, leaves yellowed, plants killed. Flytiliser is almost impossible to over-apply. Nutrients are bound within organic matter and release gradually. For gardeners who’ve killed plants with feed, that peace of mind alone is worth the price.
No. 03 — What to use it on
Works on everything.
Outstanding on these.
Beds, borders, pots, lawns — Flytiliser is genuinely all-purpose. But some crops show a response that will stop you in your tracks.
Hugely responsive to the potassium content — fuller fruit set, deeper flavour, better resistance to blossom end rot. The chitin effect helps defend against common diseases without spraying.
Cabbages, kale, broccoli, Brussels sprouts — all respond strongly to nitrogen and chitin together. Chitin’s pest-deterrent signal is especially valuable here as brassicas attract a wide range of damaging insects.
Carrots, parsnips and beetroot respond to the phosphorus content, encouraging deep, well-formed roots. The balanced, low-nitrogen profile prevents forking and excessive leafy growth at the expense of the root itself.
Heavy feeders producing enormous biomass across a long season. Flytiliser’s slow-release profile matches their steady demand far better than a single high application — consistent feeding without the boom-and-bust.
Fast-growing crops that rapidly deplete soil. Regular Flytiliser top-dressing keeps soil biology active and nutrient levels consistent through multiple cuts — better quality leaves right through the season.
Not just the veg patch. Established borders, ornamental beds, and tired lawns all respond well. For lawns: scatter at 30–50g/m² in spring and again in autumn to build soil health and reduce dependence on synthetic lawn feeds.
No. 04 — The numbers
What’s in
the bag.
NPK 3-1-3. Slow release. Chitin-active. Microbially alive. Here’s what each number actually means for your garden.
Drives leafy growth, stem strength and vigour. Slow release means sustained feeding — not a fast flush of soft growth that collapses or yellows within weeks.
Supports deep root development and establishment. Works with soil biology to improve nutrient uptake over time. Essential for transplanting and new bed preparation.
Strengthens cell walls, improves drought tolerance, boosts fruit set and flavour. Particularly valuable for tomatoes, courgettes, and all fruiting crops. Helps plants fight disease from within.
No. 05 — How it compares
Flytiliser vs
everything else.
Most gardeners are using seaweed or synthetic granules. Here’s an honest look at what they’re getting — and what they’re missing.
| Flytiliser (BSF frass) | Seaweed fertiliser | Synthetic NPK granules | |
|---|---|---|---|
| NPK profile | 3-1-3 · slow release | 0.3-0.1-1.5 · very low | Variable · fast release |
| Chitin — natural pest defence | ✓ Yes — uniquely | ✗ None | ✗ None |
| Feeds soil biology | ✓ Yes — microbially active | Mild benefit only | ✗ Can damage microbes |
| Release profile | Slow — weeks to months | Fast — days | Fast to moderate |
| Risk of burning | ✓ Very low | Very low | ✗ High if over-applied |
| Improves soil long-term | ✓ Yes — builds season on season | Minimal | ✗ Degrades over time |
| Origin | British BSF farm, Staffordshire | Wild-harvested seaweed | Manufactured / mined |
| Carbon footprint | Very low — food waste input | Low | High — energy intensive |
No. 06 — How to use it
Simple to use.
Hard to get wrong.
One 500g bag feeds a standard 4×2m raised bed for a full growing season. Scatter, water in, let it work. That’s all there is to it.
Apply before planting and fork or dig into the top 10–15cm of soil. Give it 2–3 weeks before planting to let the soil biology activate fully. Sets the whole season up right.
Scatter around the base of plants — not touching stems — and water in well. Repeat every 4–6 weeks through the growing season, March to October.
Mix into compost before planting, or top-dress established pots every 4 weeks. Particularly effective in containers where nutrients leach out with every watering.
Add one tablespoon to each planting hole before setting in your seedling. Direct root-zone contact gives the plant an immediate nutrient boost at the moment it needs it most — establishment is visibly faster.
