    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.

Different mounting mechanism than photos
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
I'm going to start off this review by stating that the mounting mechanism used on the Shelf is different than the one shown in the photo. In the photo, it shows a single bar which would have made the Shelf easier to level however, the product I received has two separate bars which means I have to be extra careful holding a level against the paper. Stencil. The reason I chose this product over different listings was because for a dollar or two more its photo showed a single bar. Now for the pros and cons: Pros: Accurate measurement. Shelf appears to be actual wood! The photos made it looks like a veneer, which it is not. Easy to install. Includes good instructions. Seems like it can hold items fairly well. Cons: The mounting hardware for drywall pretty flimsy, and I stripped out some of the drywall anchors during install. They still worked, but it was annoying to finish inserting them. The shelf doesn't sit fully flush to the wall from factory as the screws included make it protrude slightly. I can fix this with my dremel, However, This could have been solved from the factory by making the cavity slightly deeper. As mentioned above in my main detractor, it is a two bar mounting system rather than a one bar, which was shown in the photo.

Pleased overall
Color: Light Brown, Size: 4
They have an unfinished feel, and the underside screws used to hold the shelf on the poles strip out really easy. Tighten those by hand and with care. Other than that, they look great and were easy to install. Came with a full set of hardware including anchors for various wall types. Stable enough to hold small to medium sized Lego sets (don't try to put Lego Hogwarts size kits on them--not big enough). Bought 3 sets of 4 and used others as Book shelves. They work very well for novel size or paperback sized books. Just make sure you anchor them well into the wall. These will only be as good as the installation.

Nice and Inexpensive!
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
Thé shelves are good quality and easy to hang. Thé instructions do leave a bit to be desired as they misidentify which anchor to use for dry wall. I followed instructions for the first shelf and it was not very stable. I switched to the other anchors and it was great. All hardware in included. These require minimum size holes in your wall, but it is a floating shelf so be prepared to patch when you take them down.  It’s a set of 4 so a good value!

Not worth the time
Color: Light Brown, Size: 4
Plastic pieces for the dry wall broke and also created an even bigger hole in the wall. One of the shelves wouldn’t even stay level despite following all instructions. Wood gives you splinters as well since it’s not sanded down.
