Liquid seaweed fertilizer is not only organic, however it likewise originates from a sustainable source and can be harvested without harming the environment.

The majority of seaweed-based fertilizers are made from kelp, a variety of seaweed that can grow to lengths of over 50 metres. Micronutrient found in organic seaweed fertilizers include magnesium, potassium, zinc, iron and nitrogen– all of which are helpful to plants. Nitrogen, for example, is necessary to the production of nitrate, a crucial element required by plants throughout photosynthesis.

I can’t rave enough about the benefits of using a liquid seaweed fertilizer on your garden, be it on your lawns, your flower beds, your vegetables or even on your houseplants.

Where Should You Apply Liquid Seaweed Fertilizer?

Seaweed has more than 70 minerals, vitamins and enzymes. Here are just a handful of its lots of benefits and utilizes:.

Liquid seaweed solution promotes additional budding if applied as the plants are starting to bud.
It extends the service life of vegetables and fruits if used 10 days before collecting.
The extract extends the life of cut flowers if they are sprayed with it a day or more before cutting.
It can also be used as a rooting solution. Location cuttings in a solution of liquid seaweed and water till roots develop, then plant. When planting seeds or transplanting, water with the service.
If used to pasture crops, the algae increases the nutrient uptake, the protein content and total quality of the crop.
Seaweed extract likewise boosts crop yields, improves resistance of plants to frost and illness, increases uptake of inorganic constituents from the soil, strengthens resistance to stress conditions and minimizes storage losses of fruit.
It promotes vigorous development and assists discourage pests and diseases on fruit, flowers, vegetables, yards etc
. Seaweed fertilizers are especially beneficial in natural gardening. They include nearly every micro-nutrient in a completely chelated (instantly offered) form. The algae is also filled with carbohydrates, which plants use as a foundation. Numerous advantageous microorganisms likewise use carbs as a food source.
Liquid seaweed fertilizers (particularly the alginates in the seaweed) act as soil conditioners. The alginates react with metals in the soil and kind long, cross-linked polymers in the soil. These polymers improve the crumbling in the soil and swell up when they get wet. They likewise maintain wetness for a long time.

Research study on the Beneficial Results of Liquid Seaweed.

Many studies at major universities all over the world have actually yielded different findings about the favorable effects of liquid seaweed as a fertilizer, including:.

Seeds took in seaweed extract germinate more rapidly, have bigger root mass, stronger plant development and greater survival rates. Soaking plant roots in the extract likewise reduces transplant shock and speeds root development.
When plants were fertilized with seaweed scientists found that: geraniums produced more flowers per plant; grapes were sweeter; gladiolus corms grew bigger; and cucumber yields increased 40 percent (and the fruits suffered less typically from softening and rotting).
Improved yields after seaweed treatments were determined in potatoes, sweet corn, peppers, tomatoes, apples, strawberries, okra and oranges.

Essential Plant Hormones in Seaweed.

Another major component in liquid seaweed fertilizers is the hormones. The main hormonal agents in seaweed are auxins, cytokinins, betaines and gibbelerins. These hormones are vital to plant health. Most of these are just required in very little proportions, but are very important nevertheless.


There are many different auxins, and they all have their particular functions. Among their main functions is stabilizing speed of development. They have both growth-stimulating and growth-delaying functions. They likewise stimulate root growth and prevent bud forming or bud opening at the wrong times.

Seaweed can play an important function in the production of the plant’s own auxins, because the enzymes formed with the assistance of trace elements from the liquid seaweed fertilizer play an important role in the development of these auxins.


Cytokinins are another group of crucial plant hormones. They start and activate standard development procedures. The cytokinins offered in liquid seaweed extract promote development with greater vigour because they mobilize nutrients in the leaves.

They also provide defense from marginal frost (approximately -3 Celsius). Cytokinins likewise slow down the senescence (aging procedures) in the plant.


Betaines play an essential function in the osmotic processes in plants. They assist to increase the water uptake in plants and are incredibly useful in dry conditions. Betaines are also especially practical to plants under tension.

Spray Fertilizer Straight on the Leaves.

Foliar application is no doubt the most effective and effective method of administering liquid seaweed to your plants. Kelp extracts are 8– 20 times more reliable when used to the leaves than when broadcast on the soil.

Spray the fertilizer as a fine mist until it leaks off the plants’ surfaces. The plants will immediately soak up the fertilizer and start to gain from it by the second day.

Note: The other advantage I have discovered is that the liquid seaweed fertilizer applied as a foliar feed actually seems to hinder such nasty bugs as greenfly and whitefly naturally. What more could I request for!

Vary the Concentration Based on Requirement.

One benefit of using a liquid seaweed fertilizer is that you can vary the concentration according to your requirements. For example, you would most likely utilize a more diluted mixture on a lawn but would tend to use a stronger concentration for a houseplant.

Something I have discovered is that a little of this item goes a long method with some pretty excellent results. Personally, among my preferred usages for liquid seaweed fertilizer is to provide my exhibition vegetables a boost during the growing season in the hope that I will stand a better chance of protecting a few rewards once the summertime program comes around each August.

How Is Liquid Seaweed Fertilizer Made?

Liquid seaweed fertilizers are made from numerous species of seaweed that are cleaned, dried, grated and processed to allow the natural benefits to go into impact immediately upon contact with either the plants’ foliage or the soil itself. This speeds up the natural processes by transforming raw seaweed into an easily applied and quickly digested weed.

Harvesting methods make sure sustainability of the natural crop. Selecting healthy weeds growing under optimal conditions guarantees the very best growth-promoting substance yield.

Liquid seaweed extract is produced without any acid and no caustic or organic solvents. It is a truly natural product that has been thoroughly used in natural grower trials.

Seaweed Fertilizer Usage in the United Kingdom.

Seaweed fertilizer is understood in the dialects of Norman as vraic, a word that has also gotten in Channel Island English– the activity of collecting vraic being termed vraicking. In Scotland, it is used as fertilizer in lazybeds or feannagan. Falkland Islanders who gather seaweed have likewise been nicknamed “Kelpers” from time to time. Liquid seaweed fertilizer is used by much of the English and Scottish Football Premiership Premises, as well as numerous UK Champion Golf Courses.
