Liquid Kelp Fertilizer


Americans buy here

Liquid kelp fertilizers contain over 70 trace minerals.

The gentle N-P-K values make these natural, whole-food, broad-spectrum fertilizers essential to the soil food web.

More importantly, they are an excellent source of cytokinins and auxins, two essential plant growth hormones. They also contain vitamins, natural chelating agents, and amino acids.

Cytokinins improve soil tilth, regulate cell division and cell wall formation, increase photosynthesis and chlorophyll production, improve root and shoot growth, and delay senescence in the fall (when plants prepare for winter, dropping leaves, losing colour, etc.).

Auxins regulate cell elongation and mainly stimulate adventitious rooting, and promote fruit development.

I am excited to offer a second, new kelp product alongside the Kelpgrow staple. Tofino Kelp is produced by Keltsmaht Kelp, a First Nations led company based in the heart of the Nuu-Chah-Nulth territory on the west coast of Vancouver Island. Tofino Kelp is fermented using Effective Microorganisms, resulting in a fertilizer-probiotic hybrid. It is diluted at similar rates to Kelpgrow and the cost is a little lower, so I think you’ll find it attractive.

These are among the least expensive, yet highly beneficial liquid fertilizer products out there. Liquid seaweed fertilizers are a staple in any foliar feed and soil management program.

They are particularly useful when seeding and propagating, dividing, and transplanting. Growers of wheatgrass and microgreens swear by them.

The kelp used in both these products is Macrocystis integrifolia, sustainably harvested here in BC and processed quickly at cool temperatures to preserve all of the benefits seaweed has to offer. It grows well over 100 feet long, as much as 2 feet per day.

Liquid Kelp Fertilizer Application

How much do you need? Both products are highly concentrated. Kelpgrow should be diluted at a rate of 1:250 with water, whether you treat soil or containers, spray leaves, or soak seeds. Tofino Kelp is diluted 1:100 for application to soil and compost, 1:200 for spraying foliage on mature plants, and 1:400 for spraying seedlings. To soak seeds with Tofino Kelp, the optimum dilution rate is 1:50, for 4 minutes only.

Kelpgrow is amazingly effective at very small doses. All you need for lawns and gardens is 20mL (four teaspoons!) per 1,000 square feet. That’s the lowest amount of all of the liquid fertilizers I offer.

One teaspoon (4-5mL) of Kelpgrow, diluted in one liter of water, is good for 200-250 square feet. One liter, diluted in 250 liters of water, covers 50,000 sq ft — that’s more than an acre! If you farm or garden on a large scale, Kelpgrow will make sense to you.

Tofino Kelp can be used at higher rates, up to 200mL per 1,000 sq ft, though the rate is somewhat variable and dilution is more nuanced than that of Kelpgrow. It also offers the added probiotic benefits of EM. For the average city lawn and garden, and for container or indoor growing, Tofino Kelp makes sense.

Either way, in the home garden and for houseplants, don’t worry too much about the square footage. Just dilute according to use, water as usual, and spray till leaves are dripping wet. A little goes a long way.

Kelp is preferably applied in small, regular doses, such as monthly or every two weeks. It is more commonly applied directly to the plants, but soil applications are beneficial as well, especially in conjunction with effective microorganisms (such as Tofino Kelp provides).

Apply kelp using a watering can, sprayer, or irrigation system. It is best applied early in the morning, while evening would be the second choice.

How long does it keep? Liquid kelp fertilizers are good for at least one year if kept out of direct sunlight, with the cap on tight, and stored at cool room temperature. Mix and use only what you want to apply the same day. Diluted mixed product does not keep long.
