Organic Plant Feed for Stronger Growth & Healthier Roots | Natural Microalgae Biostimulant | Indoor & Outdoor Plants, Flowers, Lawns, Vegetables & Houseplants | Pet Safe & Vegan | 1L
A Feed That Actually Delivers.
Struggling roses, tired lawns, houseplants that never quite thrive — Northern Algae's Natural Plant Booster was developed to solve exactly that. It's a 100% natural, microalgae-based liquid feed that works across your whole garden: houseplants, vegetable beds, hanging baskets, lawns and borders, all from one bottle. Real customers have seen it happen — a rose bush left for dead came back to a full, healthy shrub within weeks of regular feeding, and a Poinsettia bought at Christmas was still in vivid colour seven months later, fed only every couple of weeks.
The reason it works comes down to the numbers. Trials run independently through local universities showed a 67% increase in biomass compared with a leading chemical fertiliser. Rather than chasing high NPK figures the way most synthetic feeds do, ours sits deliberately low (on average N 7.52mg/L, P 3.83mg/L, K 491.41mg/L) — because organic, bioavailable nutrition gets taken up by the plant straight away, instead of building up unused in the soil, the plant doesn’t expend energy converting synthetic fertiliser. That's what drives the stronger roots, healthier leaf colour and better flowering you'll see with regular use.
It's built to handle whatever you're growing. Feed it to vegetables, flowers, houseplants, hanging baskets or your lawn, indoors or out, without changing the routine. There's nothing synthetic in the formula, so it's safe to use around pets and suitable for vegan growers too.
Behind the bottle is a straightforward process, not a manufactured one. The microalgae is cultivated in North East England through a process that actively captures CO2, then simply harvested and bottled — no chemical treatment, nothing concentrated or altered along the way. Buying a bottle means every feed is tied to that same carbon-capturing cycle, so the environmental upside comes built in rather than bolted on.
1. Real results, independently verified:
See visibly healthier growth in weeks, not months. Independently lab-tested by local universities, our formula produced 67% more biomass than a leading chemical fertiliser in trial conditions.
2. Why lower numbers work harder:
Our NPK is deliberately low (on average N 7.52mg/L, P 3.83mg/L, K 491.41mg/L) because it's organic and bioavailable — plants absorb it immediately instead of it sitting unused in the soil like synthetic feeds.
3. Safe around family and pets:
100% natural microalgae, no synthetic chemicals. Fully pet safe and vegan friendly, so you can feed houseplants, herbs, lawns and cut flowers without worrying about children or animals nearby.
4. Works everywhere, proven by real gardeners:
One concentrated formula for indoor plants, outdoor beds, lawns, containers, hanging baskets and cut flowers. One customer's struggling rose bush transformed into a full, healthy shrub over a few weeks of regular feeding; a Christmas poinsettia fed every 2-3 weeks was still thriving and in colour seven months later.
5. Made with purpose:
Grown in North East England using a CO2-capturing cultivation process. Every bottle supports carbon capture as well as plant health — sustainability that backs up the results, not instead of them.
