DERIVED FROM Our Boric Acid 17% Boron is derived from a single, high-purity mineral source β refined to laboratory grade with no fillers or carrier agents added. Boron Source Pure Boric Acid (HβBOβ) Naturally occurring boron mineral compound refined to 99.9% purity. Provides highly bioavailable boron in a stable, water-soluble form with no chelation needed at typical application rates. A Note on Boron Form Unlike iron, zinc, manganese, and copper β which benefit from EDTA chelation for pH stability β boron as boric acid is naturally stable and plant-available across a wide soil pH range (5.5β7.5). No chelation is required or added. SCIENCE BEHIND THE FORMULA 17% Boron: Why Concentration Matters for a Micronutrient Boron is required in very small quantities β typically 0.1β0.5 ppm in hydroponic solution and 0.5β3 lbs per acre in soil. A high-purity, high-concentration source like 17% boric acid allows you to dial in precise, low doses without risk of over-application from diluted carrier products. π Cell Wall Formation Boron is structurally integrated into plant cell walls via cross-linking of pectin molecules. Without adequate boron, new growth becomes brittle, distorted, and prone to cracking β especially in rapidly dividing meristematic tissue. π¬ Carbohydrate Transport Boron facilitates the loading and movement of sugars through phloem tissue. Deficient plants accumulate starch in leaves while starving roots and reproductive tissues of energy β reducing yield and root development. πΈ Pollen Viability & Fruit Set Boron is critical for pollen tube germination and elongation. Low boron at bloom time directly reduces pollination success, leading to poor fruit set, seed abortion, and irregular fruit development in fruiting crops. Why Boric Acid Outperforms Other Boron Sources βοΈ Immediate Availability Boric acid dissolves directly into solution as borate ions (B(OH)ββ»), the form plants absorb. No conversion step needed β uptake begins as soon as the nutrient reaches the root zone or leaf surface. π Precise Dosing At 17% boron, small amounts go a long way. This makes it easy to correct deficiencies without the risk of overshooting β important because boron has one of the narrowest sufficiency ranges of any plant micronutrient. π Broad pH Stability Boric acid remains plant-available between soil pH 5.5 and 7.5, covering the full range of most commercial and garden growing conditions without the need for pH adjustment or chelation. Understanding Boron's Narrow Safety Margin Boron is unique among micronutrients: the gap between deficiency and toxicity is smaller than for most other elements. Deficiency symptoms appear below ~0.5 ppm in soil solution; toxicity can occur above ~2 ppm. Always apply at the lower end of recommended rates first, and verify with soil or tissue testing before increasing. APPLICATION RATES & DIRECTIONS Always start with lower rates and adjust based on plant response and soil or tissue tests. Boron has a narrow range between deficiency and toxicity β precision matters. Soil Application Deficiency Level Application Rate Area Coverage Frequency Light 0.5β1 lb Per acre As needed (soil test first) Moderate 1β2 lbs Per acre As needed Severe 2β3 lbs Per acre Split into 2 applications Foliar Application Crop Type Rate per 100 Gallons Timing Notes Vegetables 0.1β0.2 lbs Pre-bloom Apply early morning; avoid hot sun Fruit Trees 0.2β0.3 lbs Pink bud stage Do not apply during open bloom Row Crops 0.1β0.3 lbs 4β6 leaf stage Early morning application preferred Hydroponic / Fertigation System Type Target Boron (ppm) Stock Solution Monitoring NFT / DWC 0.1β0.3 ppm 1 g/L Weekly Drip / Ebb & Flow 0.2β0.5 ppm 2 g/L Bi-weekly Aeroponics 0.1β0.2 ppm 0.5 g/L Daily Pest Control Application Target Pest Method Rate Precautions Ants Bait stations 5% solution Keep away from pets and food areas Cockroaches Dust in cracks/crevices Light dusting Avoid food prep surfaces Silverfish Perimeter treatment 10% solution Reapply monthly; keep away from pets HOW TO USE Soil & Garden Beds Conduct a soil test to confirm boron deficiency before applying. Measure boric acid based on acreage and deficiency level (see Application Rates table). Dissolve in a small amount of water first, then dilute to desired volume for uniform distribution. Broadcast evenly or band near the root zone. Incorporate into the top 2β4 inches of soil. Water in thoroughly after application. Retest soil after 30 days to verify correction before reapplying. Foliar Spray Dissolve boric acid in warm water before adding to spray tank (enhances solubility). Add a compatible surfactant to improve leaf coverage and absorption. Apply early morning or late evening β never during peak heat or open bloom. Cover both upper and lower leaf surfaces evenly. Wait at least 14 days before repeat application. Hydroponic & Fertigation Systems Dissolve boric acid in warm water to create a stock solution. Add to reservoir gradually while monitoring ppm with a calibrated meter. Target 0.1β0.5 ppm boron depending on crop and growth stage. Check pH after addition β boric acid may slightly lower solution pH. Test boron levels weekly and adjust as needed. Flush system immediately if toxicity symptoms (leaf tip burn, leaf cupping) appear. Pest Control For ants: mix a 5% boric acid solution with a sugar-based attractant. Place in bait stations away from pets and food areas. For cockroaches and silverfish: apply a light dusting in cracks, crevices, and along perimeters using a dust applicator. Reapply perimeter treatments monthly or after rain events. Keep treated areas dry for maximum effectiveness. Pro Tip: Foliar Boron at Pink Bud for Fruit Trees For fruit trees, the single highest-impact boron application is a foliar spray at pink bud stage (just before bloom opens) at 0.2β0.3 lbs per 100 gallons. This directly supports pollen tube germination and significantly improves fruit set β especially in apples, almonds, and stone fruit. Do not spray during open bloom as it can affect bee activity on flowers. When Boric Acid Is the Right Choice Soil or tissue tests confirm boron deficiency (common in sandy, leached, or high-pH soils) Fruiting crops with poor fruit set, hollow stems, or misshapen produce at bloom time Hydroponic programs needing precise, low-dose boron supplementation Integrated pest management programs seeking a non-synthetic ant or cockroach deterrent Organic-certified growing operations requiring OMRI-compatible micronutrients When to Consider Other Options If boron levels are already adequate β over-application causes toxicity faster than with most micronutrients; always test first If you need a complete micronutrient package, consider our Micro Green 2-0-3 which includes multiple trace elements in one formula If calcium deficiency is the primary concern, Calcium Nitrate 15.5-0-0 addresses calcium alongside nitrogen without adding boron BORIC ACID CALCULATOR SAFETY & HANDLING β οΈ Important: Boron has a narrow margin between plant deficiency and toxicity. Always measure accurately and do not exceed recommended rates. Keep out of reach of children and pets. Personal Protective Equipment (PPE) Wear chemical-resistant gloves when handling or measuring Use safety glasses or goggles β fine powder can irritate eyes Wear a dust mask (N95 or equivalent) when working with dry powder in enclosed spaces Wash hands and exposed skin thoroughly with soap and water after handling Avoid touching face, eyes, or mouth during use Storage Guidelines Store in a cool, dry location in the original sealed container Keep away from direct sunlight, moisture, and heat sources Boric acid is hygroscopic β reseal tightly after each use to prevent clumping Store separately from food, animal feed, and seeds Keep out of reach of children and pets Application Precautions Never exceed recommended application rates β boron toxicity is difficult to reverse and can persist in soil for extended periods Do not apply foliar sprays during bloom or in temperatures above 90Β°F For pest control use, keep bait stations and treated areas away from pets, children, and food preparation areas Do not apply near water bodies β boric acid can be toxic to aquatic organisms at elevated concentrations Always conduct a soil or water test before applying to confirm deficiency First Aid Eye contact: Flush immediately with clean running water for 15 minutes, lifting eyelids.

FREQUENTLY ASKED QUESTIONS What is boron deficiency and how does boric acid correct it? Boron deficiency is one of the most common micronutrient disorders in plants β particularly in sandy soils, high-rainfall areas, and soils with pH above 7.0. Symptoms include stunted growing tips, hollow or corky stems, poor fruit set, thick and brittle leaves, and misshapen produce. Boric acid provides immediately plant-available boron (as borate ions) that plants absorb through both roots and leaves. Because boric acid is 17% boron, even small applications deliver meaningful correction. Learn more in our article on what boron does in plants. Is boric acid safe for organic gardening? Yes β boric acid is approved for use in certified organic growing systems when applied according to recommended rates. Our 99.9% pure formula contains no synthetic additives or carriers. Boric acid is a naturally occurring boron compound that provides essential nutrition without disrupting soil biology when used at correct rates. As with all micronutrients, the key is precision: boron has a narrow sufficiency range, so accurate application is essential for both plant health and soil safety. How does boric acid work as a natural pest deterrent? Boric acid disrupts the digestive systems of insects such as ants, cockroaches, and silverfish when ingested. It also damages their exoskeletons through desiccation over time. One key advantage over chemical pesticides is that insects do not develop resistance to boric acid's physical mode of action. In bait station applications, worker insects carry the boric acid back to the colony before it takes effect, providing broader control. For more natural pest control strategies, see our guide: A Guide to Natural Herbicides, Pesticides, and Fungicides for Your Garden. Can I use boric acid around pollinators? When used as a plant fertilizer at recommended rates, boric acid applied to soil or as a pre-bloom foliar spray poses minimal direct risk to pollinators. However, avoid applying foliar sprays directly to open flowers or during active pollinator foraging hours. For pest control applications, place bait stations in sheltered locations away from foraging areas. See our article on creating a pollinator-friendly garden and how boric acid fits into that approach. How do I know if my plants actually need boron? The most reliable way to confirm boron deficiency is a soil test or plant tissue test. Visual symptoms β hollow stems, rough or corky texture on fruit, poor fruit set, death of growing tips β are helpful indicators but can overlap with other issues. Boron deficiency is most common in sandy soils, soils with pH above 7.0, and areas with high annual rainfall that leaches micronutrients. We recommend testing before applying so you can dial in the correct rate and avoid the risk of over-application. Is boric acid safe around pets? When used as a fertilizer at agronomic rates and properly watered in, boric acid poses minimal risk to pets once incorporated into the soil. For pest control applications, keep bait stations in enclosed stations that pets cannot access, and avoid dusting surfaces where pets walk or rest. Do not allow pets to consume concentrated powder or undiluted solutions. As with any garden input, store securely and keep out of reach of animals.
