Down to Earth Seabird Guano 0-11-0 | 20lb - OMRI Listed

High-Phosphorus Guano for the Flowering and Fruiting Window, 20lb

Bloom and fruit set are the two stretches of a plant's cycle where phosphorus demand spikes hardest, and a general fertilizer's phosphorus share often isn't concentrated enough to meet it. Down to Earth Seabird Guano 0-11-0 is a high-phosphorus input meant specifically for that flowering window, applied across the mid-season stretch on both indoor and outdoor plants.

This 20lb size suits home gardeners applying Seabird Guano across a season of flowering and fruiting plants.

Key Features & Benefits

• High-phosphorus 0-11-0 ratio — concentrates on phosphorus for the flowering and fruiting window rather than spreading nutrition evenly across NPK.
• OMRI Listed — certified organic despite its concentrated, single-nutrient phosphorus profile.
• Seabird-sourced guano — derives from naturally deposited seabird guano rather than a synthetic phosphorus source.
• Mid-season timing — applied throughout the flowering period on indoor and outdoor plants alike.

Who Should Use This

Growers of strawberries, melons, vegetables, and flowers who want a phosphorus boost timed to the flowering and fruiting window, rather than an all-season blanket feed, are the right fit for Seabird Guano.

Frequently Asked Questions

Why is Seabird Guano so phosphorus-heavy compared to a balanced fertilizer?

Its 0-11-0 ratio is built specifically around the flowering and fruiting window, when phosphorus demand outpaces what a balanced all-purpose blend typically supplies. That concentration is the point, rather than a drawback, for the timing it's meant to be used in.

When during the season should this guano be applied?

It's meant for mid-season applications throughout the flowering period, on both indoor and outdoor plants. Follow current label directions for specific rates by crop and bloom stage.

Is Seabird Guano OMRI Listed?

Yes, this guano is OMRI Listed for certified organic production. Double-check the listing printed on your specific package against what your certifier currently accepts before relying on it for certified acreage.

What crops respond well to Seabird Guano?

Strawberries, melons, vegetables, and flowers are commonly cited as responding well to mid-season applications, with improvements to yield, quality, and flavor. It's best matched to plants actively flowering or fruiting rather than ones still in early vegetative growth.
