Boca Hydro Organic Gypsum
Granular Calcium Sulfate — 21% Calcium + 17% Sulfur
Boca Hydro Organic Gypsum is a premium granular calcium sulfate soil amendment designed to provide plants with two essential secondary nutrients: calcium and sulfur.
With 21% Calcium and 17% Sulfur, this high-purity granular gypsum is ideal for fruit trees, citrus, mango, avocado, garden beds, vegetables, landscapes and turf.
Gypsum supplies calcium and sulfur without adding additional nitrogen, phosphorus or potassium, making it easy to incorporate into an existing fertilizer program when additional calcium or sulfur is needed.
Premium Calcium + Sulfur Nutrition
Calcium and sulfur play important roles throughout plant growth. Calcium supports strong plant structure, active growing points, root development and fruit quality, while sulfur is involved in chlorophyll formation, amino acids, proteins and normal plant metabolism.
21% Calcium
Supplies a substantial source of calcium to help support plant structure, growing tissues, root development and fruit quality.
17% Sulfur
Provides sulfur in sulfate form for plant nutrition without adding additional nitrogen to the fertility program.
No Added N-P-K
Allows growers to supplement calcium and sulfur independently without substantially changing their primary nitrogen, phosphorus or potassium program.
pH Neutral
Gypsum supplies sulfur without functioning like an acidifying elemental sulfur amendment, making it useful where calcium and sulfur are desired without intentionally lowering soil pH.
Ideal Supplemental Amendment:
Boca Hydro Organic Gypsum can be incorporated into complete fertility programs for fruit trees,
gardens, landscapes and turf where additional calcium and sulfur are desired.
Especially Useful for Fruit Trees
Boca Hydro Organic Gypsum is an excellent amendment for established fruit trees and other long-lived crops. Granules can be distributed across the active root zone underneath the canopy and watered into the soil after application.
Why Calcium Matters for Fruiting Plants
Calcium is an important structural nutrient used throughout actively growing plant tissue. Maintaining adequate calcium availability helps support strong cell walls, healthy roots, new growth, flowers and developing fruit.
- Supplies plant-available calcium
- Supports strong cell walls and plant structure
- Supports active root growth and new growing points
- Useful during flowering and fruit development
- Helps maintain a balanced calcium fertility program
- Can supplement calcium without adding additional nitrogen
Why Sulfur Matters
Sulfur is an essential plant nutrient involved in chlorophyll production, protein synthesis, enzyme activity and amino acid formation. Crops with higher nutrient demands can benefit from maintaining an adequate sulfur supply throughout active growth.
Gypsum provides sulfur in sulfate form while simultaneously supplying calcium, making it a convenient two-in-one amendment for complete fertility programs.

Suggested Application Guidelines
Broadcast Boca Hydro Organic Gypsum evenly across the active root zone or soil surface. Avoid piling concentrated material directly against plant trunks or crowns. Water thoroughly after application to begin moving nutrients into the soil.
| Application | Suggested Rate | Application Method |
|---|---|---|
| Young Fruit Trees | 1–2 lb per tree | Spread evenly around the active root zone and water in. |
| Established Fruit Trees | 3–5 lb per tree | Broadcast underneath the canopy and around the drip line. |
| Large Mature Trees | 5–10 lb per tree | Spread throughout the root zone. Applications may be divided if desired. |
| Garden Beds | 5–10 lb per 100 sq. ft. | Broadcast over the surface and work into the upper soil or water thoroughly. |
| Lawns & Turf | 10 lb per 1,000 sq. ft. | Broadcast evenly using a suitable fertilizer spreader. |
Application rates are guidelines:
Soil conditions, plant size, crop demand, irrigation and existing nutrient levels can all affect
the appropriate application rate. Soil testing is recommended when developing a long-term
fertility program.
Easy Granular Application
Fruit Trees
Broadcast evenly underneath the tree canopy and across the root zone. Keep concentrated granules several inches away from the trunk and water thoroughly.
Garden Beds
Spread evenly across the soil surface before planting or use as a top dressing around established plants.
Lawns & Turf
Apply with a broadcast or drop spreader for even distribution and irrigate after application.
Seasonal Fertility Programs
May be applied pre-plant, during active growth as a top dressing, or after harvest as part of an ongoing soil fertility program.

Important Application Notes
Boca Hydro Organic Gypsum is intended to provide supplemental calcium and sulfur for plant growth. Actual crop requirements vary according to soil type, plant species, plant age, environmental conditions and existing fertility levels.
For best results, use as part of a complete fertility program and maintain consistent irrigation after application. Soil testing can help determine whether calcium, sulfur or other nutrients require adjustment.
Store in a cool, dry location and keep the container closed when not in use.
