Liquid Micronutrient Fertilizer · Approved for Organic Use in Canada
A liquid 3% boron fertilizer for foliar, soil drench, and fertigation use. Corrects confirmed boron deficiencies in fruit and nut trees, vegetables, alfalfa, berries, cannabis, and other crops. Derived from Disodium Octaborate Tetrahydrate.
Boron is one of the eight essential plant micronutrients. It supports cell wall formation, pollen viability, and sugar transport. Because boron is immobile in plant tissue — it can't move from old leaves to new growth — a consistent supply during flowering and fruit set is critical.
Boron-responsive crops: alfalfa, apples, pears, brassicas, sugar beets, sunflowers, celery, canola, cannabis, grapes, strawberries, tomatoes, citrus.
Test before you apply. The margin between sufficiency and toxicity is narrow. Our Soil Analysis Test can confirm whether your soil needs boron before you apply.
DIRECTIONS FOR USE
Apply only when a deficiency has been confirmed with a soil or tissue analysis. Start at the low end of any rate. Multiple smaller applications outperform single heavy ones.
Home Garden
Foliar Spray- 1–2 mL per litre of water. Apply early morning, in the evening, or during lights-off. Spray foliage until wet, no runoff. Repeat every 1-2 weeks as needed. For cannabis, discontinue foliar by week 3 of flower and all boron applications 2 weeks before harvest.
Soil Drench - Hydroponic / Fertigation / Coco / Soil Containers: Add 1 mL of Liquid Boron 3% per 30 L of finished nutrient solution (delivers ~1 ppm boron). For any reservoir, divide litres by 30 to calculate mL needed. Use a 1 mL syringe for accurate measurement.
Commercial Operations
Foliar - Mix into 20–50 gallons of water per acre (100+ gallons for air-blast orchard sprayers).
