Sea Weed Extract 250 ml

Seaweed extract is used as liquid organic bio fertilizer because of it’s organic micro nutrient, NPK and Natural Growth Hormones content such as Cytokinins, Alginic Acid, Mannitol, Gibberellins. Seaweed is Used as Plant Growth Promoter for all Kinds of Plants.

Seaweed extract is 100% natural, water-soluble, liquid organic bio fertilizer containing micro and macro nutrients, formulated Seaweed extract derived from vegetable kelp Seaweed.

Seaweed contains a sufficient amount of oceanic bio-active matter such as Phycocolloid, Mannitol, Oligose, Polyphenol, Trehalase, Cytokinin, Betaine, Lignin etc which are essential for improving germination, root development, leaf quality, general plant vigor and resistance to pathogens.

Nutritional facts:

Nitrogen(N) + Phosphorus (P2O5) + Potasium(K2O) > 3%
Calcium(Ca) + Magnesium(Mg) + Zinc(Zn) > 0.9 %
Amino acids + Fulvic acid + Humic acid > 1.88%
Aluminium(AI) + Boron(B) + Cobalt(Co) < 300 ppm

Uses of Seaweed Extract:.
1.Being rich in bio-activators (the ingredients for healthy decomposition) Seaweed is great for compost piles as it assists in speeding up the decay of other organic matter.
2.Seaweed contains large traces of potassium and natural hormones making it a hearty fertilizer that strengthens roots and a plant’s overall system.
3.It lowers vulnerabilities against diseases.
4.Its smell repels many unwanted pests and insects though it unfortunately also makes earthworms temporarily run for the hills, which is noteworthy because worms are important contributors to soil composition. However, they don’t disperse for long and in the end the benefits of applying fresh seaweed out way this temporary situation.
5.Improves the uptake of nutrients (CEC)

Seaweed Fertilizer: When To Use Seaweed Extract In Your Garden

Seaweed fertilizer is essentially plant food just like bonemeal fertilizer.

Fertilizers made from seaweed are a great source of nutrients and trace elements (absorbed from the sea) for plants grown in containers or even those grown on the ground.

They’re eco-friendly and sustainable and contain micronutrients to enrich your soil and increase crop yields.

You may find it by different names such as bladderwrack or kelp.

Although most seaweed fertilizer is marine kelp, freshwater seaweed is also rich in minerals like nitrogen, and phosphorus and may be used to supply nutrients to your plants.

What Is Seaweed Fertilizer?

Seaweed may be used whole, as a liquid or it may be composted and crushed before it is added to the soil as fertilizer.

There are different types of seaweed fertilizers generally made of kelp extract and found in varying forms such as:

  • Liquid Seaweed Fertilizer– best for plants grown in containers since it soaks through easily and plants get nutrients faster.
  • Seaweed Extract Powder– this is a very potent fertilizer and is obtained by drying out all the water from seaweed.
  • It is extracted from brown seaweed such as Ascophyllum Nodosum, Laminaria, etc.
  • Seaweed/ Kelp Meal– this is essentially dried and crushed seaweed.
  • Calcified Seaweed– this one isn’t kelp fertilizer.
  • It is a mix of calcified coral and algae (with around a 50% calcium content).

There are many different brands of seaweed fertilizer with Neptune’s Harvest (Amazon) being one of the more popular options.

Their liquid fertilizer ingredients have an indefinite shelf life since they are only activated once the water is added to them.

How Do You Use Seaweed Fertilizer in The Garden?

Seaweed fertilizers help improve your plants’ health.

They may be applied to the soil as mulch or mixed in with the compost pile.

Avoid rinsing the seaweed beforehand to remove the salt as this will take away many of its positive micronutrients and alginates.

The salt may get washed out by rainwater or hose down the soil after applying the fertilizer.

Alternatively, seaweed fertilizer can be applied through a foliar method—applying it directly onto the leaves.

Before you begin, check for and remove any dead or decaying leaves.

Use a diluted form of liquid fertilizer (liquid kelp) and spray it in the form of a light mist over the leaves.

You may either use a foliar spray for this or attach the liquid with your hose and fertilize while watering the plants.

Some gardeners may use a combination of seaweed and fish fertilizer to fertilize their house plants -this seaweed and organic fish emulsion (liquid fish) is sprayed in the foliar method.

Seaweed fertilizers can improve root growth and seed germination.

How Much Alfalfa Meal Should I Use?

Organic fertilizers are best for plants.

Many gardeners use a combination of Alfalfa meal and kelp (or seaweed fertilizer npk) to complete the NPK (Nitrogen- Phosphorus- Potassium) content of the soil.

Alfalfa meal is derived from alfalfa grass and is rich in nitrogen and calcium.

Use the following list as a guide for how much Alfalfa meal you need to use:

  • 12 lbs/ 1000 square feet for a light coat (¼ cup per plant)
  • 25 lbs/ 1000 square feet for a regular coat (1/3 cup per plant)
  • 50 lbs/ 1000 square feet for a heavy application (1/2 cup per plant)

What Are the Benefits of Using Seaweed Fertilizer in Your Garden?

Seaweed products are beneficial to your garden vegetables in a number of ways:

  • It contains nutrients such as NPK and magnesium, iron, zinc, and calcium as well as growth hormones encouraging healthy plant growth.
  • It is a form of mulch keeping the soil damp and reduces the amount of water needed.
  • It reduces the frequency with which you need to weed your garden since it doesn’t contain any seeds (possible weeds).
  • It keeps your vegetable garden free of pests such as slugs, worms, and even birds since all these creatures despise the texture and saltiness of fresh seaweed.
  • It helps plants build immunity against fungi and diseases.
  • Unlike dry fertilizers such as compost and other mulches, seaweed doesn’t blow away in the wind.
  • Seaweed fertilizer keeps the soil aerated and healthy.
  • It enriches plants grown in hydroponics by providing them with the nutrients plants generally extract from the soil.

Are There Any Downsides to Using Seaweed Fertilizer?

Since it is an organic fertilizer, seaweed fertilizer doesn’t really have any significant problems.

One of the main issues is its high salt content and this isn’t particularly detrimental to plant health.

As mentioned previously, the salt may wash out with the rain or when you water your garden.

Another minor issue is when it is applied as a mulch, it may break down faster than it can enrich the plant.

Again, this is avoidable by applying it using the foliar method or mixing it in with the compost heap.

Other than this, there aren’t any significant downsides to using seaweed fertilizer.

How to Feed Seedlings with Seaweed Extract Fertilizer

If your new baby seedlings are a few weeks old now, it may be about time to feed them for the first time! In best practice, seeds are sowed in very mild, light, fluffy seedling starting soil mix, which is generally pretty devoid of nutrients. That is fine (for now) because tiny seedlings do not need or like fertilizer in the first couple weeks after sprouting. It can actually harm them, or “burn” the seed and prevent germination!

On the other hand, as they begin to grow, that fluffy seedling mix quickly becomes too light and won’t be nutritious enough to keep them happy for very long. Fertilizing seedlings with seaweed extract can help solve that! It is gentle, sustainable, and effective.

Let me show you how we fertilize our seedlings seaweed extract fertilizer to help keep them healthy and strong! It is very simple, and will make for a pretty quick post! At the end, you’ll find a demonstration video.

When do I start to fertilize my seedlings?

Seeds are pretty amazing little things. The seed itself contains all the food and nutrients that the little plant they produce needs for those first few weeks after sprouting. But as they start to mature, they’re also going to start to get hungry. Like any good baby should, they will get very cranky if you don’t feed them when they want it. Signs of distress include yellowing leaves, stunted growth, and even disease or death.

The best time to start fertilizing your seedlings is before they begin to get cranky. It is a lot better to keep them satiated then wait until they’re in trouble, and try to correct the damage. This is sort of a Goldilocks and The Three Bears kind of story. Not too early, not too late, not too much. We want “just right”.

Wait until after first couple sets of “true leaves” appear, and then start to feed them very lightly. About 3 to 4 weeks after germinating is a good target, about the time you’d want to start to thin them also.

What are true leaves? When a seed germinates, the first set of little leaves that emerge (often heart-shaped, and often looking exactly alike between dozens of varieties of veggies) are not the true leaves. These are the cotyledon leaves – their embryonic leaves. The two leaves that come after the cotyledon are their “true” leaves. Those leaves will more closely resemble what the mature leaves of the plant will look like.

These seedlings are TOO SMALL to be fed any fertilizer yet! The image in the top right show the heart-shaped cotyledon on a bunch of broccoli, bok choy, kale, and mustard greens. The lower right are tomato sprouts, and the on the left is a tomatillo. Wait another week or two, until the true leaves become larger and another set starts to appear.

If you’re going to plant your seedlings outside or pot them up within a few weeks after germination, it may not be completely necessary to feed them in their starting container. When they are planted outside in a bed of rich soil, or into a larger container with fresh soil and compost, they’re going to be essentially “fed” in that process. Yet if you are like us, and keep seedlings in containers for two or three months before planting them outside, they’ll definitely want a few rounds of food during that time.

What should I fertilize my seedlings with?

Many gardeners, us included, like to use a dilute organic seaweed extract fertilizer. It is nice and mild, making it very difficult to shock or harm your seedlings unless you really overdo it.

Seaweed extract helps the plants grow bigger and develop stronger root systems. Both of these contribute to overall improved plant health and immunity. Just like people, a plant with a strong immune system has a stronger ability to fight off disease, pests, or rebound from stress. Seaweed extract is loaded with over 70 beneficial vitamins, minerals, micronutrients, and enzymes! It contains magnesium, potassium, zinc, iron and nitrogen – to name just a few.

Cold-pressed kelp is commonly used to make seaweed extract. The harvest and cultivation of kelp is widely recognized as sustainable and environmentally-friendly! This is an excellent (and often overlooked) multi-purpose fertilizer; one that can be used for much more than seedling care! When we don’t have time to make a batch of compost tea, we water our garden beds or house plants with it too. Additionally, seaweed extract can be used to make foliar sprays. The plants can then absorb all that good stuff straight through their leaves.

Edit: We used to use this seaweed extract (at the time of writing this post), but the formula recently changed and it no longer says OMRI listed for organic gardening. I’m not sure what’s up, but we since switched to this organic seaweed extract instead.

From the book “Seaweed Sustainability” – Academic Press:

“Seaweeds grow in abundance in the oceans, many of which are edible and safe for human consumption. They have been documented to contain many of the essential nutrients such as omega-3 fatty acids, amino acids, vitamins, minerals, and bioactive compounds.

For many years, seaweeds have also been cultivated and utilized directly as food for humans or as feed to produce food for human consumption (e.g. fertilizer). Since seaweeds grow in many climatic conditions globally, their cultivation has minimal impact on the environment. Seaweeds are increasingly recognized as a sustainable food source with the potential to play a major role in providing food security worldwide.”

Kritika Mahadevan, Chapter 13 – Seaweeds: a sustainable food source

Kelp is such amazing stuff, that in addition to feeding it to our plants, we take some for ourselves too! No, not this liquid fertilizer… but in the form oral supplements. Algae is the only plant-based, vegan, or vegetarian source that contains all the most beneficial and essential forms of omega 3-fatty acids that are usually lacking in other plant sources. If you’re curious, read all about that here.

Another option people use for fertilizing seedlings is liquid fish emulsion. We don’t personally use this, so I won’t speak on its behalf.

How do I feed my seedlings seaweed extract?

Mix the seaweed extract with water according to the instructions on the bottle. If possible, use de-chlorinated water on seedlings. We use captured rainwater. If you allow chlorinated water to sit out, like in a bucket for example, the chlorine will dissipate in a day or two. If your city uses chloramines instead of chlorine to disinfect their water, it won’t burn off. When we can’t use our rain water, another option is to hook up this basic RV carbon filter to a hose – and that takes care of it.

Some types of seaweed extract have varying instructions for different types of plants or stages of growth. Look for instructions clearly intended for seedlings, or as a soil drench. We use about an ounce per one gallon of water, maybe just a touch over that sometimes.

Personally, I like to mix it inside this one-gallon watering can, especially for watering seedlings or working in the greenhouse. It is easier to handle than a larger 2 gallon can, and I really love the long, curved, skinnier spout. The design makes it very convenient for watering from below, as described next.

Wait a few days after the last time you watered, until the plants are getting a little thirsty and are due for another routine watering. Now, feed the seedlings the dilute seaweed extract mixture in place of their regular water. To accomplish this, we prefer to water from below.

Watering from below, into the trays. A note about our seedling trays: we prefer to use these heavy-duty seedling trays. They’re incredibly durable, will not crack, and can even hold bricks without bending! In addition to their longevity and strength, they’re perfect for watering from below. We still have some older flimsy 10×20 trays that aren’t totally “broken” and fairly functional, but this year I noticed most of them have developed little pinholes in the corners! This means all the liquid leaks out when practicing watering from below. And…. I figured this out the hard way, using a tray inside!

Feeding seedlings seaweed extract from below:

If you aren’t familiar with the concept of “watering from below”, it is exactly what it sounds like. It’s accomplished by pouring water (or in this case, seaweed solution) into the tray the seedling containers are sitting in. The soil will draw up moisture from the bottom, soaking up as much as it needs until the soil is evenly saturated.

Simply pour enough seaweed solution to evenly fill the bottom of the tray (with the containers still sitting inside of it) to about a half an inch deep. It is important that your trays are sitting level to ensure all the seedlings are getting a similar amount of seaweed solution. Otherwise, the liquid may pool on one side and leave the other thirsty.

After adding the seaweed solution to the tray, wait about an hour to see what happens. Did they already suck it all up, but seem a bit dry still? If so, you may need to add a little bit more. Alternatively, is the soil totally saturated, but a lot of liquid remains in the tray?

Allowing seedlings to sit in soggy conditions is not ideal. They breathe through their roots and do not want to drown. Therefore, we try to remove any leftover standing liquid from the trays within a few hours. Or, at least by the next day if we get busy. You can do this by either very gently tipping it out (if possible), or using a large garden syringe thing to suck it out. Yes… it is easiest if you don’t have a bunch of excess, so I suggest to go lighter at first and add more if needed.

How often to feed seedlings seaweed extract?

You can generally feed seedlings seaweed extract every two to three weeks, depending on the brand. Again, read those instructions! After feeding, you should see an immediate boost in growth.

Voila!

It is as simple as that. If you follow these steps to feed your seedlings, they will thank you and feed you right back!
