Garden Addicts BioSpark – Biological Soil Activator - - - [1ltr]
Description BioSpark is a liquid fertiliser made in New Zealand that combines direct plant nutrition with biological soil activation. Most liquid fertilisers do one or the other. This one does both. The NPK analysis is genuinely useful: 10% nitrogen and 11% potassium put it in the range of a real top-up feed rather than a trace supplement. Alongside that, the VM3 organics blend introduces beneficial microorganisms that improve nutrient cycling and organic matter breakdown, while the VAM (Vesicular Arbuscular Mycorrhizae) gets to work on the root system directly. VAM is a symbiotic fungi that colonises plant roots and extends its own hyphae deeper into the soil profile than root hairs can reach. It can colonise up to 80% of the root mass and helps dissolve bound phosphorus and trace elements, making them available to the plant. On compacted, depleted, or heavily chemically-managed soils where microbial activity has dropped off, reintroducing VAM can make a real difference to how efficiently plants use the nutrients already in the ground. BioSpark works as a liquid top-up within a broader fertiliser programme, or on its own for gardeners who prefer a fully biological approach. It’s well suited to vegetable gardens, lawns, ornamentals, fruit trees, and pot plants. How to use Garden beds, soil drench Mix with water and apply to moist soil during active growth. Water in well after application. Do not mix with fungicides or chlorinated water as this will damage the microbial content. Foliar spray Dilute and apply to foliage in the early morning or late afternoon. Good for a steady top-up between soil applications. Shake the bottle well before use. Lawns Apply through a watering can or sprayer. Water in afterwards. Every 3 to 4 weeks through the growing season gives the biology time to establish. Pot plants Apply to moist potting mix at pot-appropriate rates. Pots tend to lose beneficial biology faster than garden beds, so regular application is worthwhile. Frequency Every 2 to 4 weeks during active growth is recommended. Consistent use gives the microbial populations time to establish and build up, which is where the longer-term soil benefit comes from. Application rates: Garden beds (soil drench) 50–80 mL per 10 L water, covering 10 m² Foliar spray 50–80 mL per 10 L water Lawns 200–300 mL per 5 L water per 100 m² Pots & containers Small (up to 15 cm): 3–5 mL per 1 L water Medium (20–25 cm): 5–10 mL per 1–2 L water Large (30–45 cm): 10–20 mL per 2–4 L water
