    Q: Why is seaweed good for plants?

    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.

Awesome little shelves!
Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch, Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch
These shelves are actually pretty neat. Super easy to install with provided hardware and measurement paper. It's the perfect size for For smaller collections and even some frames if you wanted. I enjoyed the different styles to choose from when it comes to personal preference. Comes in three sizes for all your decor needs. Wasn't as thin as I thought it would be, now the feel isn't the greatest, but the look is pretty sweet. Held up just fine and the placement for the brackets are pretty cool. Either floating, bracket facing up or down. ideal for anyone who wants a nice looking shelf without breaking the wallet.

They hang easy!
Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 23-inch, Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 23-inch
I got my shelves well packaged. No defects. I did find it odd that the photos show a third way of hanging them where the brackets are hidden, but it's the only two top shown in the product photo of the hanging options that are shown on the instructions. It's easy enough anyway to hang without any instructions and I chose the second one shown anyway. They're good quality and look nice on my wall. Color is accurate and holds all my stuff the way I'd hoped/imagined. I wanted shelves that didn't stick out too far from the wall and they're a great fit. Super sturdy!

Great product!
Color: G. Black Board & Gold Brackets, Number Of Shelves: 3, Size: 16-inch Mixed, Color: G. Black Board & Gold Brackets, Number Of Shelves: 3, Size: 16-inch Mixed
The feeling of the shelf itself is a little off but it was super easy to put together and looks great! It comes with a mounting guide but I didn’t need it. I didn’t use to wall anchors and just screwed them into the wall and they haven’t been a problem at all!

Avoid the GOLD brackets. The finish is NOT accurate.
Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch, Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch
I bought the BLACK/GOLD shelves because the ones in the photo seemed to match the drawer pull knobs I bought (shown in photo below). The product arrived neatly packed in a 17x6x4in. box. I can only assume the shelves themselves are great, but I only made it as far as inspecting the metal brackets sitting at the top, they feel heavy duty, which is great, but the product's photo posted in Amazon shows a nice gold finish, and these brackets have a dark mustard paint finish (with a couple blueish speckles sprinkled into it), there's nothing gold/metallic about it. The paint color reminded me of long-gone diaper-changing days. These are getting returned asap.
