    Liquid kelp, also known as seaweed extract, is a natural fertilizer made from seaweed. It contains a variety of beneficial nutrients, growth hormones, and trace elements that can promote plant growth and health. Many different types of plants can benefit from the application of liquid kelp, including:

     

    Vegetables: Various vegetables such as tomatoes, peppers, cucumbers, zucchini, broccoli, and leafy greens can benefit from liquid kelp's nutrients, which can lead to improved yields and overall plant health.

     

    Fruits: Fruit-bearing plants like strawberries, blueberries, grapes, citrus trees, and apple trees can benefit from liquid kelp, which may enhance flower and fruit production.

     

    Herbs: Culinary and medicinal herbs like basil, mint, cilantro, and oregano can thrive with the help of liquid kelp, as it supports their nutrient uptake and essential oil production.

     

    Ornamental Plants: Flowers and ornamental plants, including roses, orchids, lilies, and many others, can experience improved root development and enhanced flowering when treated with liquid kelp.

     

    Lawns: Applying liquid kelp to lawns can improve soil health, stimulate root growth, and increase the lawn's ability to withstand stressors like drought and disease.

     

    Shrubs and Trees: Landscape shrubs and trees, such as azaleas, rhododendrons, and various ornamental trees, can benefit from the use of liquid kelp to support their growth and overall vitality.

     

    Indoor Plants: Houseplants, such as spider plants, pothos, peace lilies, and many others, can also benefit from the application of liquid kelp, providing them with essential nutrients for healthy growth.

     

    Liquid kelp can be applied as a foliar spray or as a soil drench, and it is generally considered safe and beneficial for most plants. However, as with any fertilizer or plant supplement, it's important to follow the recommended application rates and guidelines to avoid over-fertilization, which could be detrimental to plants. Always read the product label and follow the manufacturer's instructions for the best results.

Great for thick hair!
Set name: 4.23 Fl Oz
I’ve used many hair oils over the years, but this one is a standout! I recently purchased Achieve Thicker Hair Pure Batana Oil on Amazon, and it has quickly become a favorite in my hair care routine. From the moment I opened the bottle, I was greeted by a subtle, natural aroma that felt so refreshing. The oil has a lightweight texture and is packed with pure, natural ingredients. I appreciate that it’s cold-pressed, ensuring all the nutrients are preserved. Using it is super simple—I massage it into my scalp and hair, leave it on for about 30 minutes, and then wash it out. The results have been incredible! My hair feels softer, looks shinier, and I’ve already noticed a decrease in breakage and dryness. I plan to use this oil regularly to keep my hair healthy and strong. If you’re looking for a high-quality hair oil that delivers real results, I can’t recommend this one enough! Give it a try—you’ll love the difference it makes.

Nice so far
Set name: 4.23 Fl Oz
I got this product on a whim. I have severely dry ends that are frayed at this point. Upon initial use, it seems to have made it a bit smoother (I opted for the overnight treatment option). I read a review that said it smells like peanut butter, and I see the potential. Having that in mind it visually reminds me of pure, organic peanut butter; the color and oiliness along with that faint smell really brings it in together. I love how it’s hard to liquid, easy to pick up product and melt to apply. As someone with sensory sensitivity I despise the texture of the oil, but that is a me thing nothing to complain about the actually product. If you are someone who does not like to touch heavy oils, I recommend you find someone else to apply for you, or maybe an entirely different product. I am desperate enough to deal with it. I just got this last night I will follow up in a few months.
