Boca Hydro Organic Citrus Heal Zinc Supplement for all Citrus and Nut Trees. 20% Zinc + Seaweed Amino Acid Plant Growth Enhancer

Why Zinc Is Essential for Citrus

Zinc is an essential plant micronutrient involved in many of the biological processes that control normal plant growth.

Although plants require only relatively small quantities, inadequate zinc can dramatically affect the appearance and development of new foliage.

Zinc participates in:

• Numerous plant enzyme systems
• Protein metabolism
• Carbohydrate metabolism
• Normal shoot elongation
• Leaf expansion
• Growth regulation
• Healthy vegetative development
• Normal reproductive growth

Maintaining adequate zinc is therefore especially important when citrus trees are producing vigorous new flushes of shoots and leaves.

Extremely Concentrated — 20.5% Zinc

Citrus Heal contains 20.5% zinc, making it a highly concentrated specialty micronutrient product.

That high concentration means growers can deliver useful zinc nutrition with very small quantities of product.

It also means precise dilution matters.

12% Amino Acids

Citrus Heal combines its concentrated zinc source with 12% amino acids.

Amino acids are fundamental building blocks used by plants to construct proteins, enzymes and other compounds required throughout normal growth.

Plants naturally synthesize amino acids through their own metabolism, but amino-acid-containing plant supplements can complement a complete fertility program during periods of rapid growth and increased environmental demand.

This combination makes Citrus Heal particularly well suited to citrus trees entering an active growth flush, when new leaves and shoots are developing quickly.

Foliar Application — The Preferred Method for Citrus

For citrus zinc supplementation, foliar application is the primary recommended use for Citrus Heal.

Applying a properly diluted zinc solution directly to young foliage provides a targeted way to supplement zinc without relying entirely on root-zone availability.

This can be especially useful in alkaline or calcareous soils where zinc may be present in the soil but poorly available to plant roots.

For best foliar performance:

• Apply during an active growth flush.
• Target young leaves that are approximately two-thirds to fully expanded.
• Apply as a fine, even spray.
• Wet foliage thoroughly without excessive runoff.
• Apply during early morning or late afternoon.
• Avoid application during extreme heat.
• Avoid spraying severely drought-stressed plants.
• Allow sufficient drying time before expected rainfall.

Why High-pH Soil Can Create Zinc Problems

A soil may contain zinc and still fail to supply enough zinc to citrus roots.

Root-zone chemistry strongly influences micronutrient availability. As soil pH becomes increasingly alkaline, zinc commonly becomes less available to plants.

This is particularly important in citrus-growing regions with naturally alkaline soils, limestone-based soils or irrigation water containing substantial alkalinity.

Under these conditions, repeated heavy soil applications of zinc may be less efficient than properly timed foliar applications.

Citrus Heal allows growers to bypass some of these root-zone limitations by delivering zinc directly to actively growing foliage.

Designed for New Citrus Growth Flushes

Citrus trees frequently produce new growth in distinct flushes rather than continuously throughout the year.

These periods of rapid leaf and shoot development create increased demand for micronutrients involved in new tissue formation.

For trees with a known history of zinc deficiency, application during active new growth provides an excellent opportunity to supplement zinc before deficiency symptoms become severe.

New growth should be monitored after treatment to evaluate whether normal leaf size, color and shoot development are improving.

Perfect for Citrus Trees

Useful Beyond Citrus

Although Citrus Heal is formulated and marketed primarily for citrus, zinc is an essential micronutrient for virtually all plants.

When properly diluted, Citrus Heal may also be incorporated into micronutrient programs for other crops where zinc deficiency has been identified.

Precision Matters With Zinc

Zinc is essential, but plants require it in much smaller quantities than macronutrients such as nitrogen, phosphorus, potassium, calcium or magnesium.

Citrus Heal's high concentration is an advantage because very little product is required, but this also means growers should measure carefully.

• Do not increase rates simply because symptoms are severe.
• Use a measuring syringe for sub-milliliter applications.
• Use foliar application as the primary correction method for citrus.
• Consider soil pH when deficiency repeatedly returns.
• Account for zinc already supplied by other fertilizers and micronutrient blends.
• For commercial programs, tissue and soil analysis provide the best guidance.
