Our Fruit and Vegetable Fertiliser is a carefully formulated blend of premium organic ingredients to produce a slow-release powdered fertiliser crafted for a wide range of fruits and vegetables – delivering increased yields of larger, sweeter, more flavourful produce all season long.

This versatile all-purpose formula provides a balanced supply of Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Humic Acid, and Micro-Nutrients, plus natural growth promotors from seaweed and malted barley. It combines traditional, time-tested organic materials with premium regenerative ingredients to support robust growth, abundant harvests, and exceptional taste across crops like tomatoes, peppers, beans, leafy greens, root vegetables, berries, and more.

Benefits of Our Fruit and Vegetable Fertiliser

• Balanced Nutrient Profile: Supplies essential NPK along with Calcium, Magnesium, Humic & Fulvic Acids, and trace micro-nutrients (from boron to manganese) – promoting strong vegetative growth, root development, fruit set, and enhanced sweetness/flavour without excess nitrogen dilution.
• Blend of Fast and Slow-Release Nutrients: We source each nutrient from multiple premium inputs (e.g., potassium from potash, polyhalite, dried worm castings, castor meal, and seaweed) for immediate availability plus sustained release.
• Premium Ingredients - We only use the finest ingredients possible whether that is Micronised Rock Phosphate which due to its fine particle size is easy for the plant to uptake or the Yorkshire Polyhalite mineral used at Wimbledon to keep the grass green.
• Increased Yield and Flavour: Rich in phosphorus and potassium for more fruits of larger size and better quality, with micro-nutrients ensuring sweet, complex flavours. Natural growth enzymes and hormones from Scottish seaweed and diastatic malted barley boost overall plant vigour, aroma, and nutrient density.
• Premium Ingredients: Only the finest sources, including micronised rock phosphate (for easy uptake), Yorkshire polyhalite (used at elite venues like Wimbledon for sustained nutrition), Scottish seaweed, dried worm castings, basalt rockdust, clay minerals, and fermented biochar.
• Organic & Sustainable: All ingredients are certified organic and sourced as locally as possible in the UK, with fully compostable packaging.
• Multi-Input Fertiliser: Unlike single-ingredient products (often waste-based and imbalanced), our blend of 13+ premium sources ensures perfect nutrient harmony and complete essential elements.
• Local Sourcing – We buy British ingredients where possible such as our Scottish Seaweed and Yorkshire Polyhalite and produce the fertiliser on-site in Cheshire.
• Builds Soil Health: Promotes beneficial microbes, improves structure, water retention, and long-term fertility – avoiding salt build up from synthetics that harms soil and flushes out good organisms.
• Handcrafted Quality: Made in the UK in small batches by hand, ensuring consistency and care in every bag.

Why use organic fertilisers?

1. Microbial nutrient processing: Nutrients require microbes to break down, generating secondary metabolites that enhance flavour, aroma, and nutrient density – why organic produce often tastes superior.
2. Reduced nitrate levels: Dramatically lower nitrates (30–50% vs. synthetics) for cleaner, healthier, better-tasting fruits and veg.
3. Reduced pollution: Non-water-soluble nutrients resist leaching, preventing runoff and ecosystem harm.
4. Enhanced soil health: Adds organic matter, boosting microbial diversity for better performance, fewer diseases, and resilient crops.
5. Slow-release nutrient delivery: Gradual release from polyhalite, alfalfa meal, etc., lasts weeks/months – minimising burn and applications.
6. Improved soil structure and water retention: Binds particles for better aeration, drainage, and drought resistance.
7. Support for biodiversity: Encourages earthworms, mycorrhizal fungi, and beneficial organisms for natural pest deterrence and fertility.
8. Lower environmental footprint: Renewable UK-sourced materials reduce emissions and support sustainable farming.

Directions for Use Soil Preparation (Pre-Planting or Transplanting)

• Soil Beds/Raised Beds: Apply 100–200 grams per square metre. Work lightly into the top 10–15 cm of soil. This gentle rate suits diverse crops without overwhelming roots.
• Single Plants: Mix 2–3 tablespoons (30–50 grams) into the soil around the plant at transplanting. Leave a 10 cm gap from the stem to prevent burn.
• Potted Plants/Containers: Mix 1.5 – 3 teaspoons (7.5–15 grams) per litre of soil or potting mix. Mix thoroughly; containers need balanced release for steady feeding.

Feeding (Ongoing Maintenance)

Start 10–14 days after transplanting (once established). Apply every 2-4 weeks during the growing season, or as crops need (e.g., reduce in late season for flavour focus). Monitor for excess growth and adjust.

• Rows/Beds: 100–200 grams per metre of row. Spread evenly, lightly scratch in, and water well.
• Single Plants (In-Ground/Raised Beds): 2–3 tablespoons (30–50 grams) per plant. Apply in a ring around the drip line (10–15 cm from stem) and incorporate lightly.
• Potted Plants: 0.5 – 1.5 teaspoons (2.5 – 7.5 grams) per litre of soil/pot volume. Top-dress or mix into top soil and water thoroughly.

We recommend mixing with equal compost before applying – this reduces dust, activates microbes (including EM and biochar), and enhances nutrient breakdown for better flavour/yield.

Additional Tips

• Versatile for fruits (berries, tomatoes) and vegetables (peppers, beans, roots, greens) – moderate N supports balanced growth, higher P/K boosts yield and taste.
• In UK conditions, water deeply after applications to activate slow-release.
• Soil test annually (target pH 6.0-7.0) to tailor rates; complementary amendments (mycorrhizal fungi, seaweed extract) amplify results.
• Stop/reduce late season if plants thrive – focuses energy on flavour over excess foliage.

Supporting Research on Organic Fertilisation for Yield and Flavour in Fruits & Vegetables

• Global meta-analysis (2023) of 7859 data pairs: Combined NPK + organic sources improved yield by ~31% and nutritional quality (sugars, vitamin C, carotenoids, etc.) by ~12% on average, with vegetables/fruits highly responsive; balanced multi-nutrient organics excel for flavour.
• Trials on tomatoes and mixed crops: Balanced organic NPK (with seaweed, humic acids, etc.) increased sugars (up to 45%), vitamin C, and flavour compounds while sustaining yields; multi-source slow-release supports better quality than single-ingredient fertilisers.
• Studies on organic amendments (worm castings, seaweed, polyhalite): Enhanced micro-nutrients, soil health, and secondary metabolites for sweeter, more aromatic produce with 15–30% flavour boosts.

Recommended Amendments to Enhance Results 

To further optimise flavour, aroma, yield, and overall plant health, consider incorporating these complementary amendments alongside your core fertiliser regime. Each has been selected based on robust scientific evidence showing benefits for peppers, particularly in organic or regenerative systems.

• Mycorrhizal Fungi: Inoculate seedlings or apply at planting (slurry method recommended). AMF extend root systems for better uptake, increasing fruit yield (up to 20–50%), soluble solids (Brix for sweetness), ascorbic acid, phenols, aroma compounds, and stress tolerance. Meta-analyses confirm higher antioxidants and sensory quality.
• Seaweed Extract: Apply as foliar spray every 7–14 days. Acts as biostimulant with hormones and bioactives; research shows boosts in yield (up to 65% under stress), soluble solids, flavonoids, vitamin C, and flavor profile, plus enhanced aroma and nutrient efficiency.
• Liquid Calcium Sulphate (Gypsum): Apply as soil drench every 2–4 weeks. Provides available calcium without pH change; trials link to firmer fruit, reduced disorders, better shelf life, and consistent quality in variable conditions.
• Additional Humic Acid (or Humic/Fulvic Acids): Use as soil drench every 2–4 weeks. Chelates nutrients, stimulates roots/microbes; studies report 15–30% higher Brix/sugars, antioxidants, and flavour/nutritional value.
• Cover Crops (e.g., Rye, Radish, or Legume Mixes): Sow in autumn/winter, incorporate as green manure in spring. Builds organic matter, suppresses diseases; long-term trials show enhanced pepper yields, soil health, and reduced issues.
