FoxFarm Big Bloom Organic Liquid Plant Food — 1 Pint Concentrate for Flowering & Fruiting Plants, Bat Guano & Worm Castings

FoxFarm Big Bloom Liquid Plant Food is an OMRI-listed, organic liquid fertilizer made with bat guano and earthworm castings to support flowering and fruiting plants at every stage.

Big Bloom is designed for gardeners who want an organic, easy-to-use liquid feed that encourages flowers, fruits, and healthy vegetative growth without synthetic additives. This 1-pint concentrate mixes readily into water and can be applied by hand, hose-end sprayer, or through drip systems. With a mild 0-0.5-0.7 NPK profile and natural ingredients, it supplies trace elements and micro-nutrients to improve bloom set and overall plant vigor.

How quickly will I see results after feeding Big Bloom?

Because Big Bloom is a soluble liquid formula, many gardeners notice greener leaves and revived blooms within a few days of application. Results depend on plant size, soil condition, and watering practices, but the fast nutrient uptake makes it a good option for quick correction.

• Visible leaf color improvement often within 48–72 hours.
• Better flower set over the following 1–3 weeks with regular use.
• Works well as a corrective feed for potted plants and containers.

What is the best way to apply this organic bloom fertilizer?

Mixing is simple: combine 4 tablespoons (about 60 mL) of Big Bloom per gallon (4 L) of water and apply every other watering. It is compatible with watering cans, hand sprayers, hose-end sprayers, siphon mixers, and drip irrigation systems—making it flexible for beds, containers, and greenhouse use.

• Standard feed: 4 tbsp per gallon every other watering.
• Use with drip or hose-end systems for even coverage.
• Reduce frequency for seedlings and newly transplanted young plants.
