desertcart.com : Wiggle Worm 100% Pure Organic Mineral-Dense Worm Castings Fertilizer, 30lbs - Improves Soil Fertility and Aeration for Growing Better Houseplants, Vegetables, and More : Patio, Lawn & Garden

Review: Thru a program of organic amendments like Azomite rock dust to actively aerated compost teas and ... - I have been building the fertility of my garden soils for the past 4 years since I created the first raised beds. Thru a program of organic amendments like Azomite rock dust to actively aerated compost teas and biochar, I have been putting it all on there. I have been learning all along the way. I decided to kick it up a notch this year with some Worm Castings in bulk. I currently use all my kitchen scrapes for soldier fly larvae so I don't have much left for a worm bin. The idea of another component that needs daily or weekly maintenance and tending wasn't appealing either. I may try an "in-garden" worm tower in the future but for now I was looking for some good castings at a good price. I have been using castings in my AACT (actively aerated compost tea) recipes for several years now and am familiar with a couple of brands. I wasn't sure how this Unco Industries Wiggle Worm brand would compare, but after getting some in, all I can say is that I'm highly impressed. Worm Gold Plus has been my first choice brand for years. But with limited availability here on desertcart, I decided to look at other options. I received in my compost tea kit I ordered this year, a couple of pounds worth from a brand called Organic Solutions. It is also not listed in quantity on desertcart. I finally settled on the 30 lbs bag from Wiggle Worm and took a chance and ordered it. Sold By desertcart with Prime Shipping it was only $24. What a bargain for 30 lbs. I was such a good price with good feedback I had to try it. So now I have 3 brands on hand to compare. If you don’t see it listed for $24 be sure to check out “new available from other sellers”. Here are some photos of all 3. And here are my observations: None of the castings have a bad odor. All of them smell earthy and nice. They all have a nice dark chocolatey brown color. Worm Gold Plus - The bag I have is much more compacted than the other 2 brands. I have to break it apart to use it. There are few clearly defined castings. It is a bit thick like clay. It takes a bit of work and time to break the clods apart especially for adding to your soil mixes where you may want a finer texture. The issue I have with it is that it is/has or is heading toward going anaerobic conditions. Organic Solution - These castings were fine and moist and easy to flow thru your fingers after grabbing a handful. There were lots of little bits of what looks like woody material mixed in. If this material is there to foster and grow more fungi then I will have to say that it is my favorite. There are a lot of little critters running around that you can see with the naked eye too. These castings are produced in California by a family owned company in smaller batches. The food source given to the worms are pre-consumer waste stream products that are free from toxins and contaminants. It is high in chiton and microbes that use chiton as a food source. Supposedly these microbes will live on your plants and provide a deterrent to pests landing on your plants for dislike of getting eaten by these microbes. Also when worms consume chiton it is broken down into chitonase which is then absorbed by the plants and when aphids and the likes begin to feed on the plants that have chitonase in their systems, it as an enzyme will begin to dissolve their exoskeletons. High chitonase worm castings are an excellent natural insect repellent. Supposedly you can put them 1/4” thick on fire any beds to get rid of them! Well I tried it and it actually worked. 3 days later the ant bed was abandoned. I think this has to be my favorite brand of all. I limit using these to my compost teas and prized plantings. But to get 30 lbs worth would cost around $40 or more plus shipping. This is the best stuff around IMO, but I was looking for good quality bulk castings to add in quantity to my transplants and garden beds. Unco Industries Wiggle Worm Castings - These are moist and of a fine texture. It is very consistent in appearance. It is produced by UNCO Industries out of Oregon. They have been in business since 1976. These are also very good quality castings. For bulk application rates these can’t be beat for the price if you order it from desertcart for $24 per 30 lb bag shipped Prime. I have ordered 3 bags of these this year and plan on ordering more. Thank you desertcart. 5 stars for an affordable, quality product. Just what I was looking for. Now to get that garden growing with some record size and flavored veggies and fruits. Happy Gardening!
Review: Perfect product - I recently purchased Wiggle Worm 100% Pure Organic Earthworm Castings, and I couldn’t be happier with the results. The product arrived quickly and was packaged securely, with no tears or spills. It was delivered in perfect condition, which I appreciated given how messy some garden supplies can be. As soon as I opened the bag, I could tell this was high-quality stuff. The castings are rich, dark, and have a pleasant earthy smell. I’ve used various soil amendments in the past, but these castings are some of the best I’ve come across. I started using the worm castings in my vegetable garden and indoor plants immediately. The results have been fantastic. My plants have responded really well—there’s been a noticeable boost in growth and vitality. My tomatoes, in particular, have been thriving with lush green leaves and more flowers than ever before. Even my houseplants look happier and healthier. One of the things I love about Wiggle Worm castings is that they are completely organic. I’m very conscious about using natural products in my garden, and knowing that this product is free of chemicals and synthetic ingredients is a huge plus. It’s also gentle enough to use on delicate seedlings, which is great because I don’t have to worry about burning or damaging young plants. The castings are easy to use. I simply mix them into the soil or sprinkle them around the base of my plants. They blend well and don’t create any mess or unpleasant odor. Plus, a little goes a long way, making this a cost-effective solution for enriching my garden soil. Overall, I’m extremely satisfied with Wiggle Worm 100% Pure Organic Earthworm Castings. They’ve become a staple in my gardening routine, and I’ve seen a marked improvement in the health and productivity of my plants. If you’re looking to give your garden a natural boost, I highly recommend this product. It’s high-quality, easy to use, and delivers excellent results.
