    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.

I was sent this package with the item dirty. Black stains throughout as if it was worn right before selling it, which IT WAS. I found someone’s ID in the pocket and chewing gum wrapper. Never again.

Loved it.. Slim fit Prom suit!
Size: 30, Color: White
I absolutely loved this suit!! It fit my son PERFECTLY!! It’s a true slim fit like the kids like these days. I’ve bought several suits online and none of them fit like this one. They SAY slim fit but they’re not. This one was!! 👌🏽 My son is small. He’s a Junior this year and wears a size 30… it’s true to size! ❤️ He’s about 5’8” 125lbs and still had some room in the length. He would of got the length hemmed a bit cuz he likes his pants right above his ankle. If your son is taller, you might not have to hem. We ordered the white. Unfortunately I had to return it because his girlfriend switched color schemes from pink & white to pink & black so he wore a blk suit he already had. I was tempted to still keep it because that’s how much I liked it on him. He liked it too 😩 But chances are he wouldn’t be able to fit it next year so I decided to return it. But, I’m definitely buying this suit again next year… hopefully the other colors fit like the white one, just incase his girlfriend wants a different color. The white was not see through. Very good quality especially for the price. I felt bad returning it… but trust me, I’ll definitely buy it again next year for homecoming/prom!!

Good but true to size, don’t size up even if the company says too!
Color: Black, Size: Large, Color: Black, Size: Large
It fits the way it should and is a decent suit for $100 and is super soft material so the outside feels great and the inside is silky so it is all around a good suit. But the company reached out and asked for measurements to double check sizing. I ordered a large and giving measurements and all that, the company told me to size up and order an XL. Definitely should have gone with a large. It was extremely long in the pants and sleeves due to upsizing.

Great Quality and Value, With a Small Detail to Note
Color: Brown, Size: Small
Gorgeous suit. The only downside for us is that the lines are diagonal rather than a traditional pinstripe. Other than that, the suit is very well made. Great value for the price, and the sizing is accurate plus fast shipping that right there are great reasons to add this to your suit rotation.
