Florikan Sapphire Aluminum Sulfate | 50lb (40/PL)

Coated Aluminum Sulfate for Blue Hydrangea Bud Color

Blue hydrangea coloration depends on a steady, well-timed supply of aluminum, and repeat manual applications of an uncoated form both raise labor cost and risk uneven runoff. Florikan Sapphire Aluminum Sulfate is designed to increase the development of blue flower color in blue Hydrangeas using a patented polymer coating technology to sustain nutrient release.

Sold as a 50lb bag, 40 per pallet, coated for gradual release specifically on Hydrangeas.

Key Features & Benefits

• Formulated specifically for blue hydrangeas — the product's sole named, labeled use case.
• Patented polymer coating technology — sustains nutrient release to support blue bud coloration over time.
• Reduces potential nutrient runoff and leaching — compared to an uncoated aluminum sulfate application.
• Controlled release reduces need for multiple applications — one incorporation covers more of the production cycle.

Who Should Use Florikan Sapphire Aluminum Sulfate

This fits nursery and greenhouse growers producing blue-variety hydrangeas who want a coated aluminum sulfate that sustains release and cuts down on repeat manual applications.

About Florikan Sapphire Aluminum Sulfate

Sapphire Aluminum Sulfate is manufactured by Florikan using the company's patented polymer coating technology, applied here specifically to sustain aluminum sulfate release for blue hydrangea bud color.

Frequently Asked Questions

How and when should Sapphire Aluminum Sulfate be applied?

Incorporate it into the growing media during blue hydrangea production, since it's formulated to sustain release across the crop cycle rather than deliver aluminum in a single burst. Its coated release means growers don't need to reapply as frequently as they would with an uncoated form.

Why does aluminum sulfate need a polymer coating?

Florikan's patented polymer coating technology sustains the release of nutrients specifically to reduce potential nutrient runoff and leaching into the environment. That controlled release is also what reduces the need for multiple applications compared to an uncoated product.

What crop is this product formulated for?

It's labeled for use on Hydrangeas, and specifically designed to increase the development of blue flower color in blue-variety plants. It isn't positioned as a general-purpose acidifier or micronutrient product.

How does this reduce labor compared to uncoated aluminum sulfate?

Because the controlled release technology reduces the need for multiple applications, growers spend less time on repeat manual treatments across the hydrangea production cycle. That's in addition to the reduced runoff and leaching risk the coating provides.

What size and packaging is this listing?

It ships as a 50lb bag, 40 per pallet, sized for commercial blue hydrangea production. That volume suits nursery and greenhouse operations running hydrangea crops at scale.
