Kelp Meal Fertilizer
Dry kelp meal fertilizer made from seaweed to support growth and stress tolerance. Apply it to soil for slow, steady feeding and a simple source of kelp-based plant nutrition.
Apply it to the soil as directed, water it in, and let the dry formula provide steady nutrition between feedings—no liquid mixing required.
Why You'll Love It
- Healthier Soil Dry kelp meal worked into soil for slow, steady release.
- Steady Growth Feeds gradually rather than all at once, so plants get a long supply.
- Complete Nutrition Seaweed-based nutrition that supports growth and stress tolerance.

How to Use Kelp Meal Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Small to medium plants (spring & summer) | 1/2 - 1 tsp, sprinkled evenly around the plant and gently mixed into the top of the soil, then watered | Apply every 1-2 weeks |
| Large plants (spring & summer) | 2 - 3 tsp, sprinkled evenly around the plant and gently mixed into the top of the soil, then watered | Apply every 1-2 weeks |
| Fall & winter (all sizes) | Same amounts | Apply every 2-4 weeks |
| Compost tea (optional) | 2 - 4 tsp per gallon of compost tea | Add when brewing |
This is a dry meal, not a liquid — sprinkle it around the plant, scratch it gently into the soil surface, and water as usual. No mixing or dilution needed unless you're brewing it into compost tea.
What's Inside
One ingredient: dried, ground Ascophyllum nodosum — the cold-water Norwegian kelp used across the TPS line, here in whole-meal form for organic gardens. Kelp isn't an NPK fertilizer in the usual sense; its value is everything mineral analysis doesn't capture: natural growth-promoting compounds, plus the broad spread of trace minerals seaweed concentrates from ocean water, released gradually as soil microbes break the meal down.
That slow breakdown is the point of the meal format. Where a liquid feed is available immediately and gone in weeks, kelp meal worked into the topsoil feeds soil organisms for a season, improving the biological activity that unlocks nutrients already in your soil. It pairs with, rather than replaces, your regular fertilizer — the meal builds the soil while the fertilizer feeds the plant, and a scoop in the compost tea brewer extends the same benefit to everything you water with it.
Made For
Organic vegetable gardens, raised beds, flower beds, roses, shrubs, fruit trees, and container plants — anywhere you're building soil rather than just feeding a plant — plus compost piles and compost tea brewing.
Problems It Solves
- Garden soil that's gone lifeless after years of synthetic-only feeding
- Plants that respond weakly to fertilizer despite regular applications
- Transplants and new beds slow to establish
- Compost tea brews missing a mineral-rich food source
FAQs
How often should I apply kelp meal?
Sprinkle it evenly around the plant, gently mix it into the top of the soil, and water as usual — 1/2 to 1 tsp for small to medium plants, 2 to 3 tsp for large ones. Apply every 1-2 weeks in spring and summer, dropping to every 2-4 weeks in fall and winter. For compost tea, add 2-4 tsp per gallon when brewing.
Is kelp meal a complete fertilizer?
No — and it isn't trying to be. Kelp meal is low in NPK by nature; what it delivers is growth-promoting compounds, trace minerals, and food for soil microbes as it breaks down. Plants still need a primary nutrient source, whether that's rich compost or a regular fertilizer. Think of kelp meal as the soil-building layer underneath your feeding program, not a substitute for it.
How is kelp meal different from liquid kelp or seaweed extract?
Same seaweed, different clock. Liquid kelp and extracts are processed for immediate availability — fast to act, gone in weeks, ideal for a quick response. Meal is the whole dried kelp, ground: it has to be broken down by soil life, so it acts slowly and keeps working for months. Meal builds soil over a season; liquid gives plants a direct, short-term push. Many gardeners run both.
Is this safe for organic vegetable gardens?
Yes — it's a single-ingredient product, dried Norwegian kelp, made for organic gardens. Work it into the soil around edible crops at the label rate and wash harvested produce as you normally would. As with any soil amendment, it's for feeding plants, not for human or animal consumption directly, so store it sealed and out of reach of children.
Can I add kelp meal to my compost pile or compost tea?
Both. In the pile, kelp meal adds trace minerals and feeds the microbial activity that drives decomposition — a light dusting between layers is plenty. For tea, the label rate is 2-4 tsp per gallon while brewing, which dissolves kelp's soluble compounds into a liquid you can water in anywhere, effectively converting the slow meal into a faster-acting feed.
When will I see results?
Slower than a liquid fertilizer, on purpose. Kelp meal works through the soil, so the first several weeks are microbial — nothing visible. Expect plant-level differences over 4-8 weeks of regular use: sturdier new growth, better response to your regular feeding, transplants establishing faster. The full payoff is cumulative across a season as soil biology builds. For fast visible change, brew it as tea.
