For more flowers, richer colour and better flavour.
Many flowering and fruiting plants don’t reach their full potential because they run short on phosphorus and potassium just when they need it most. The result: fewer flowers, smaller fruit and weaker flavour.
TerraSoil BioBurst Flower Mix is an organic bloom booster that gently feeds your plants during the flowering and fruiting stage. With natural sources of phosphorus and potassium, plus supporting minerals, it helps produce:
- More abundant, vibrant blooms
- Improved flower fragrance and better-tasting fruit
- Stronger, healthier plants that finish well
BioBurst works in garden soil, potting mix, raised beds and coco. It’s 100% organic, slow-release and easy to use as a soil mix or top-dress, for both home gardeners and professional growers.
Key Benefits
- Promotes heavy blooms – Organic phosphorus and potassium fuel flower and fruit production.
- Improves flower quality – Bat guano and seaweed support fragrance, flavour and resin.
- Gentle, slow-release feeding – Natural ingredients break down gradually, reducing the risk of burning.
- Works in any medium – Suitable for soil, coco coir and potting mixes.

TerraSoil BioBurst Flower Mix – Organic Bloom Booster for Vibrant Flowers & High
When to start
- Begin using BioBurst about 2 weeks before plants start to flower for best results.
Pots & containers
- New plantings:
- Mix 10 g per litre of potting mix before planting.
- As an easy guide, that’s about 1 small handful (30–40 g) for every 10 L of soil.
- Established plants:
- Sprinkle 1 small handful around the base of each plant on top of the soil.
- Gently work it into the top few centimetres of soil and water well.
Garden beds & borders
- Spread 100–150 g per square metre of soil around flowering or fruiting plants.
- This is roughly 3–4 small handfuls per square metre.
- Lightly rake into the soil surface and water thoroughly.
Larger plants, shrubs & fruit trees
- Use up to 200 g per plant as a top-dress around the drip line (where the outer leaves reach).
- Spread evenly and water in well.
How often to apply
- Reapply every 4–6 weeks during the flowering and fruiting period.
Tips
- Always water after applying BioBurst so nutrients can move into the root zone.
- Use together with a good organic base soil or compost for the best results.
