🌾 HOW TO USE
Soil Drench
Mix 3–5 mL per litre of water and apply every 7 days during periods of rapid growth or heavy rains.
Frequent Irrigation
Use 1 mL per litre of water with every watering for ongoing support.
Blossom End Rot Prevention
Apply weekly throughout fruiting stages to prevent calcium-related deficiencies.
Foliar Application
Use 2–4 L per hectare. Spray directly onto plant foliage to the point of run-off as needed throughout the growing season.
Soil Application
Use 8–16 L per hectare, applied in irrigation water until soil is saturated. Continue every 7–14 days at 2 L per hectare as needed.
Hydroponic & Soilless Systems
Use 1–2.5 mL per litre of water in the reservoir once per week or as needed throughout the plant's lifecycle.
Nursery & Container Plants
Mix 5–15 mL per litre of water. Apply as a foliar spray or soil drench. Continue use throughout the season as needed.
Turf & Lawns
Apply 80–150 mL per 100 m² through irrigation. Maintain with 25 mL per 100 m² every 7–14 days as needed.
