Down To Earth Island Phosphate 0-11-0 | 5lb - (Case of 6)

High-Phosphorus Bloom Feed for Bud Set and Flower Development, 5lb

Bloom quantity and size are tied directly to phosphorus availability during the flowering phase, and a balanced all-purpose fertilizer doesn't always supply enough of it when a plant shifts into bud set. Down To Earth Island Phosphate 0-11-0 is built specifically for that window, delivering 11% phosphorus with no added nitrogen or potassium to compete for uptake.

The 5lb bag, sold as a case of six, is convenient for home gardeners and indoor growers applying Island Phosphate during the flowering phase across a season's worth of plants.

Key Features & Benefits

• 0-11-0 concentrated phosphorus — supplies phosphorus without added nitrogen or potassium during the flowering phase.
• Supports bloom quantity and size — phosphorus availability during flowering is directly tied to bud set and bloom development.
• For indoor and outdoor plants — suited to a wide range of flowering annuals, ornamentals, and fruiting plants.
• Can be brewed as a bloom tea — filter after steeping in water for a liquid application option.

Who Should Use Down To Earth Island Phosphate 0-11-0

This fits home gardeners and indoor growers who want to supplement phosphorus specifically during the flowering phase of annuals, ornamentals, or fruiting plants rather than relying on a balanced all-purpose fertilizer alone.

Frequently Asked Questions

What is Island Phosphate 0-11-0 used for?

It's used to supplement phosphorus specifically during the flowering phase of plant growth, since phosphorus availability is closely tied to bud set, bloom quantity, and bloom size. It carries no added nitrogen or potassium.

Can Island Phosphate 0-11-0 be used as a liquid tea?

Yes, it can be steeped in water and filtered to make a bloom tea for application through irrigation or as a drench. Filter thoroughly before applying to avoid clogging any spray or irrigation equipment.

What plants can Island Phosphate 0-11-0 be used on?

It's suited to indoor and outdoor flowering plants broadly, including annuals, ornamentals, and fruiting plants moving into their flowering or fruiting stage. Any plant entering bud set can potentially benefit from added phosphorus.

When should Island Phosphate be applied?

Apply it during the flowering period rather than earlier in vegetative growth, since that's when phosphorus demand for bud set and bloom development is highest. Follow the current label for specific rates and timing by plant type.

Why does Island Phosphate carry no nitrogen or potassium?

The 0-11-0 ratio is designed for growers who already have nitrogen and potassium covered through a base fertilizer program and want to add phosphorus specifically, rather than shifting the whole nutrient balance of an existing feeding schedule. Adding a balanced fertilizer instead would raise nitrogen and potassium levels that may already be sufficient.
