Boca Hydro EDTA Fruit and Flower micronutrient blend for professionally managed citrus and fruit tree orchards

Boca Hydro EDTA Fruit & Flower Micronutrient Blend 3-3-3

Concentrated Boron, Zinc and Magnesium Nutrition for Flowering, Fruit Set and Premium Crop Quality

Boca Hydro EDTA Fruit & Flower Micronutrient Blend is a highly concentrated specialty fertilizer developed for commercial orchards, fruit farms, vineyards, greenhouses, nurseries and serious home growers who need precise control over boron, zinc and magnesium nutrition.

Producing high-quality fruit requires more than supplying nitrogen, phosphorus and potassium. Trees must also have access to very small but essential amounts of micronutrients during flower-bud development, bloom, pollination, fruit set and early fruit growth.

When micronutrients become limiting, an orchard may continue to look generally healthy while producing weak or uneven bloom, poor fruit set, malformed fruit, irregular development or foliage that cannot photosynthesize at full capacity.

This concentrated formula supplies 7% boron, 5% zinc and 2.5% magnesium, together with a supporting 3-3-3 NPK analysis. It is designed to supplement an existing fertility program without requiring large additions of base fertilizer.

Boron supports reproductive growth, flower development, pollen function, sugar movement and normal tissue formation. Zinc supports enzyme activity, shoot development, protein production and normal plant metabolism. Magnesium supports chlorophyll formation, photosynthesis and the maintenance of an efficient fruit-producing canopy.

Because these nutrients are required in extremely small quantities, a relatively small amount of product can treat hundreds or thousands of gallons of finished solution. Preparing the recommended concentrate allows precise measurement with a syringe, graduated cylinder, dosing pump or fertilizer injector.

Commercial Orchard Formula NPK 3-3-3 7% Boron 5% Zinc 2.5% Magnesium EDTA-Based Blend Precision Low-Rate Feeding Fully Water Soluble

Designed for Commercial Fruit-Production Challenges

Weak or Uneven Bloom	Flowering is one of the most nutritionally sensitive stages in fruit production. Inadequate micronutrient availability before and during bloom may limit normal flower development even when an orchard receives adequate NPK fertilizer.
Poor Pollination & Fruit Set	Boron supports normal reproductive-tissue development and pollen function. Correcting an actual boron shortage can help support more uniform pollination and fruit establishment.
Malformed or Uneven Fruit	Micronutrient imbalances during flowering and early fruit development may contribute to irregular fruit formation and reduced marketability. Precision supplementation supports nutrient availability while young fruit tissues are developing.
Weak Canopy Performance	A productive orchard requires healthy leaf area to capture sunlight and manufacture the carbohydrates used to size and mature fruit. Magnesium supports chlorophyll, while zinc supports enzymes and normal plant metabolism.
Hidden Micronutrient Hunger	Trees may experience reduced productivity before severe visual symptoms become obvious. High-pH soil, alkaline irrigation water, sandy or heavily leached soil, stressed roots and nutrient interactions can reduce micronutrient availability.
Heavy Crop Demand	High-yielding trees remove nutrients through harvested fruit and place additional demand on leaves, roots and reproductive tissues. Targeted supplementation can be incorporated without greatly increasing total nitrogen or fertilizer salts.
Precision Fertility Management	Commercial growers can make small, controlled nutrient adjustments based on crop stage, source-water analysis, soil testing, leaf-tissue analysis and observed plant response.

Product Benefits

Flower-Bud Development	Supplies boron and zinc to support normal flower-bud differentiation, reproductive growth and flower formation.
Pollination & Fruit Set	Supports the nutritional conditions required for normal pollen function, flower retention and early fruit establishment.
Fruit Shape & Uniformity	Helps maintain balanced micronutrient availability during the early stages when fruit structure, shape and uniformity are being established.
Canopy Efficiency	Magnesium supports chlorophyll formation and photosynthesis, helping the canopy manufacture energy and carbohydrates for fruit growth.
Enzyme & Metabolic Support	Zinc supports enzyme systems, protein formation, shoot development and normal plant metabolism.
Controlled Nutrient Input	Provides concentrated micronutrients without forcing growers to apply large quantities of nitrogen, phosphorus or potassium solely to address a trace-element limitation.
Multiple Application Methods	Suitable for foliar feeding, pots, containers, soil drenches, hydroponics, coco, rockwool and properly diluted fertigation programs.

Commercial Orchard Application Strategy

Pre-Bloom Programs	May be incorporated into a carefully managed pre-bloom nutrient program when crop history, soil testing or tissue analysis indicates low boron, zinc or magnesium availability.
Bloom & Fruit Set	Low-rate foliar or root-zone applications may be used to support micronutrient availability during flowering and early fruit establishment. Always avoid excessive boron.
Early Fruit Development	Supports the developing canopy and young fruit during periods of active tissue formation and increased demand for plant energy.
Post-Harvest Programs	Where appropriate for the crop, post-harvest supplementation may be incorporated into a program intended to restore nutrient reserves and support development of the following season’s buds.
Deficiency Correction	Can be applied through foliar spraying, irrigation or root-zone drenches when a deficiency is suspected or confirmed. Begin with the lowest applicable rate and evaluate crop response before repeating.
Professional Monitoring	Commercial programs should be guided by soil analysis, irrigation-water analysis, leaf-tissue testing, crop stage, previous applications and the nutrient contribution of all other fertilizers.

A Small Amount Treats a Large Volume of Water

Why Make a Concentrate?	Plants require boron and zinc in extremely small quantities. Preparing a master concentrate allows fractions of a gram to be measured accurately and distributed evenly.
Routine Foliar Coverage	At a foliar rate of 0.3-0.4 g per gallon, only 100 g of product prepares approximately 250-333 gallons of finished foliar spray.
Root-Zone Coverage	At a finished rate of 0.05-0.10 g per gallon, only 100 g of product prepares approximately 1,000-2,000 gallons of finished root-zone solution.
Precision Fertigation Coverage	At a final irrigation rate of 0.01-0.02 g per gallon, only 100 g of product treats approximately 5,000-10,000 gallons of irrigation water.
Low Storage Requirement	The concentrated analysis reduces the amount of fertilizer that must be stored, transported, measured and introduced into the orchard compared with dilute micronutrient blends.
Professional Control	Growers can adjust micronutrient input without materially changing the orchard’s primary NPK program, irrigation EC or overall fertilizer strategy.

WARNING — Contains Boron: This fertilizer contains added boron and is intended for use only on directed crops. Use on other crops, or under conditions other than those recommended, may result in serious crop injury. Do not combine with other boron-containing products unless the total boron contribution has been calculated.

Precision Product — More Is Not Better: Boron has a narrow range between deficiency and excess. Measure carefully, begin at the lowest listed rate and do not exceed label directions.

Commercial Grower Recommendation: Use as a targeted supplement rather than a replacement for a complete orchard fertilizer program. Base repeat applications on soil testing, leaf-tissue analysis, irrigation-water quality, crop load, growth stage and previous fertilizer inputs.

Compatibility: Conduct a jar test before preparing a large or unfamiliar mixture. Do not combine concentrated stock solutions unless compatibility has been confirmed. Add products separately to the final irrigation water whenever possible.

Solution Management: For hydroponic and soilless systems, maintain the final nutrient solution within the pH range recommended for the crop, generally around 5.5-6.5. Monitor EC, source-water nutrients and the complete fertilizer program.

Application Safety: Do not apply to heat-stressed, drought-stressed or visibly damaged plants. When crop sensitivity is unknown, test a small number of plants before widespread application.

Storage: Store the dry product tightly sealed in a cool, dry location. Protect from moisture and humidity. Keep prepared concentrate covered, clearly labeled and out of reach of children and pets. Shake or stir before measuring if settling occurs.
