Premium Organic Fertiliser from Black Soldier Fly Frass

Root & Rise™– Signature is a next-generation natural fertiliser and soil enhancer designed for gardeners who want lush, healthy plants without compromising on sustainability or safety. Made entirely from 100% pure insect frass—the soil-enriching castings of Black Soldier Fly (Hermetia illucens) larvae—this premium, organic input delivers a potent blend of slow-release nutrients, beneficial microbes, and soil-conditioning compounds in one finely textured product. Sourced from insect larvae raised exclusively on clean, plant-based food waste, Root & Rise offers a unique, circular solution that supports your plants while restoring soil health. It’s naturally rich in bioavailable nitrogen (3.5%), phosphorus (2.0%), and potassium (2.8%)—in ratios ideal for strong root development, vigorous leaf growth, and flowering performance. But it doesn’t stop at NPK. With over 70% organic matter and a perfectly balanced pH of 6.5–7.2, it helps improve soil structure, boost microbial activity, and support water retention in all soil types. What truly sets Root & Rise apart is its ability to promote long-term soil and plant vitality through nature’s own immune-support system. The frass contains naturally occurring chitin and a broad spectrum of beneficial microbes, both of which stimulate a plant’s natural defence pathways—enhancing resilience to pests, diseases, and stress conditions. No harsh chemicals, no concentrated salts, and no animal waste means it’s safe to use around pets, pollinators, and children, making it an ideal choice for organic gardens, raised beds, lawns, orchards, and potted plants alike. Whether you’re top-dressing vegetable beds, boosting fruit tree performance, or reinvigorating tired potting soil, Root & Rise is easy to apply and works with your plant’s natural rhythms. Its fine, dry consistency blends seamlessly into soil or compost, and its slow-release nature means longer-lasting results with fewer applications. Crafted in the UK and packaged in resealable, kraft-based pouches to maintain freshness, Root & Rise is a low-impact, high-performance alternative to synthetic fertilisers and manure-based products. It reflects a regenerative philosophy: waste turned into nourishment, soil turned into life. Grow boldly, grow naturally. With Root & Rise™, you’re not just feeding your plants—you’re building a living soil ecosystem from the ground up.
