GS Plant Foods Liquid Kelp Fertilizer 1 Gallon Concentrate — OMRI-Listed Seaweed, Makes 800+ Gal

GS Plant Foods Liquid Kelp Fertilizer is an OMRI-listed seaweed concentrate that feeds roots, improves soil biology, and supports greener, more resilient lawns, gardens and ornamentals.

This concentrated Ascophyllum nodosum kelp extract is formulated for organic growing and dilutes to make over 800 gallons of feed solution from a single 1-gallon bottle. Gardeners and landscapers use it to encourage stronger root systems, assist nutrient uptake, and support plant vigor across lawns, vegetables, flowers and shrubs. Because it’s OMRI listed, it fits into certified organic programs and is suitable for growers who want a natural, marine-derived plant stimulant rather than synthetic chemistry.

How do I use this kelp fertilizer in my garden?

Mix the recommended dilution for foliar spray or soil drench according to plant type and growth stage. Apply during active growth, and avoid treating during the hottest midday hours to prevent foliar burn; early morning or late afternoon is best. Regular, moderate applications provide steady benefits without overfeeding.

• General dilution: follow label for rates (concentrated to make 800+ gallons).
• Apply as a soil soak or foliar spray every 7–14 days during growing season.
• Use more frequently for seedlings and transplants to establish roots.

What plant benefits can I expect from Ascophyllum nodosum seaweed?

This kelp fertilizer supplies naturally occurring hormones, trace minerals and organic compounds that support root growth and strengthen plant responses to environmental stress. It helps plants mobilize nutrients already in the soil rather than acting as a primary N-P-K source, so pairing with balanced fertilizers can give fuller nutrition. Effects are cumulative, improving soil biology and plant vigor over multiple applications.

• Improves root development and root mass for better nutrient and water uptake.
• Supports greener foliage and more consistent growth under stress.
• Can enhance flowering, fruit set and overall plant productivity.

Is this product safe for organic growing and which crops can I use it on?

GS Plant Foods Liquid Kelp is OMRI listed and compatible with National Organic Program standards, making it acceptable for certified organic production when used as directed. It’s a versatile amendment suitable for vegetables, herbs, ornamentals, fruit trees, shrubs, lawns and container plants. Always follow certification rules and label instructions for organic program compliance.

• OMRI listed for use in organic systems.
• Safe for edible crops when used according to label directions.
• Works well in soil, in raised beds, containers, and turf applications.

How does one gallon translate to coverage and mixing convenience?

The concentrate is formulated to stretch a little or a lot depending on dilution rates—one gallon can produce more than 800 gallons of ready-to-use solution for light maintenance sprays. That makes it cost-effective for large lawns, community gardens or commercial use. For small gardens, the concentrate stores easily and you mix only what you need for each application.

• One gallon concentrates into over 800 gallons of spray at maintenance rates.
• Easy to measure and dilute for targeted applications or large-scale spraying.
• Long shelf life when stored cool and out of direct sunlight.

Who is this for: GS Plant Foods Liquid Kelp Fertilizer suits hobby gardeners, organic growers, landscapers and commercial producers who want a natural seaweed-based plant stimulant. It’s especially useful for anyone establishing transplants, improving soil biology, or looking to support plants facing environmental stress. If you need an OMRI-listed, marine-derived foliar or soil amendment that mixes concentrated for wide coverage, this product is designed to fit into both small-scale and larger production routines.
