Adding kelp to soil can improve soil health by providing essential nutrients like potassium and trace minerals. It also helps increase microbial activity, leading to better plant growth and overall crop yield. Consider using kelp as a natural fertilizer for your garden.
Kelp contains potassium, iodine, magnesium, and iron, and cytokinins found in seaweed are natural growth hormones that drive dynamic plant development and higher yields.
Soil Health & Fertility
Organic kelp additions slowly decompose, enriching soil with vital organic matter that improves texture and retains moisture. This process creates a perfect environment for beneficial microbes to thrive, ultimately boosting soil fertility over time.
Eco-Friendly Protectors Against Pests & Diseases
By incorporating seaweed or kelp into your gardening, you can harness their natural defenses against pests and diseases.
The unique compounds in these marine elements help plants resist fungal infections and insect attacks.
Gardens with seaweed have stronger defense mechanisms, reducing the need for chemicals.
Varieties of Seaweed and Kelp for Optimal Soil Health
- Ascophyllum Nodosum: They have balanced nutrient mix, it’s particularly effective in boosting plant vitality.
- Kombu (Laminaria): A potassium-rich variant that help development of flowers and fruits.
- Wakame (Undaria Pinnatifida): Can help stimulating beneficial soil bacteria.
- Norwegian Kelp: Renowned for its ability to improve seed germination rates significantly.
Each type is packed with essential micronutrients like iodine, calcium, and magnesium which are crucial for robust plant growth.
Prime Sources of Seaweed and Kelp
- Seaweed can often be collected directly from the beach—always check local regulations regarding collection practices.
- Specialty Organic Stores: These outlets may offer unique or locally-sourced seaweed options not available elsewhere.
I contacted my local beach mangement leader, and got apporovel to pick washed up kelp from a beach.
Offical the could not approve the harvesting, but I got an unoffical approval to take what I wanted. It is in many ways a win win deal. I clean the beach from unwanted washed up kelp, while the beach gets cleaner.
I wait until after easter to let any bird eat what they need in winter time.
One benifit of pivking washed up seeweed are that it have been natural claned for a year by rain and snow.
Key Considerations If You Buy Seaweed Products
- Select suppliers that practice sustainable harvesting methods to preserve our natural resources.
- Find products devoid of pollutants or excessive salt residues which could detrimentally affect plant growth rather than nurture it.
- Formulation Type:
- Raw: Perfect if you prefer an all-natural approach by incorporating directly into compost heaps or concocting homemade liquid fertilizers.
- Processed Forms (e.g., pellets): While these might include additional ingredients that enhance their nutritional value, always scrutinize labels thoroughly.

Where to buy seaweed fertilizers
Organic Sea-K kelp powder from Greenleaf Nutrients can be found at Amazon, the price per now is $ 9,90 per 200 Grams.
Organic Liquid Seaweed from Bloom City can be found on Amazon, the price is $19.99 for 0.94 Liters concentrated liquid. Liquid kelp is better if you want to use it as a foliar spray fertilizer, where you apply it on the leaves.
How to add seaweed or kelp to garden soil
The first step in harnessing the power of seaweed or kelp is ensuring they are impeccably clean. This involves meticulously removing any residual salt, sand, or tiny marine inhabitants that might be attached. Start by vigorously rinsing them under a strong flow of water—preferably using collected rainwater or dechlorinated tap water to keep the beneficial microorganisms intact.
Eliminating Salt Residues
Desalination is critical—it safeguards your garden crops from the detrimental effects of excessive salt accumulation in the soil. Submerge your cleaned seaweed or kelp in a bucket filled with fresh water overnight. Refresh this water multiple times until it stays clear, signaling that most salts have been effectively removed.
Drying for Optimal Storage
Post-rinsing, spread out the seaweed or kelp on a flat surface under direct sunlight; utilizing a mesh screen will facilitate optimal air circulation. Allow them to dry thoroughly; this may take one to two days depending on climatic conditions. Properly dried seaweed and kelp not only last longer but also integrate more easily when mixed into soils or added to compost piles.
Preparing for Future Applications
Once dry, chop up these nutrient-rich sea greens into smaller fragments—a tactic that simplifies future use whether you’re amending soil directly or enhancing compost mixes with organic matter. Store these chopped pieces in breathable containers such as burlap sacks which deter moisture buildup and keep pests at bay.
By meticulously following these steps before introducing seaweed and kelp into your garden’s ecosystem, you ensure each strand significantly boosts plant health and elevates fertility levels within your natural haven.
How to add seaweed or kelp to garden soil
1. Direct Application:
- Technique: For the straightforward gardener, scattering dried seaweed or kelp meal directly onto the soil proves both simple and effective. Distribute the dry material around plant bases throughout the growing season.
- Advantages: This approach gradually releases nutrients as it breaks down, ensuring a consistent nutrient flow that bolsters plant development.
- Points to Consider: Aim for uniform distribution to prevent nutrient concentration spots which could disrupt soil balance.
2. Composting with Seaweed and Kelp:
- Technique: Blend seaweed or kelp with other organic residuals like kitchen leftovers and lawn clippings in your compost bin.
- Procedure:
- Shred or tear the seaweed/kelp into smaller fragments to expedite decomposition.
- Intermix these bits within your compost heap, alternating with carbon-rich agents such as dead leaves or straw.
- Regularly turn the pile to oxygenate and promote breakdown.
- Advantages: This method boosts microbial life, enhancing nutrient availability when this enriched compost is introduced to the garden soil.
3. Creating Liquid Fertilizers:
- Technique: Often referred to as “seaweed tea,” liquid fertilizers are dynamic solutions that channel nutrients straight to plant roots for immediate absorption.
- Steps:
- Steep dried seaweed or kelp in water (ideally collected rainwater) for roughly two weeks.
- Filter out solids—these remnants can be returned to the compost—and dilute if needed before application.
- Application: Administer this tea by dousing at plants’ bases or foliar feeding through gentle leaf sprays.
- Benefits: Swift uptake aids stressed or newly transplanted crops in quickly establishing themselves.
Timing & Dosage Guideline
- When applying dry meals directly, use modestly—a handful per square yard during planting suffices.
- For teas and extracts, apply every four weeks during peak growth periods but lessen frequency as temperatures decline.
- Always conduct a patch test first if concentrations are uncertain.
