        			Soon to be known as the "World's Greatest Organic Fertilizer!" Wiggle Worm Soil Builder PURE earthworm castings are surely Mother Nature's best kept growing secret. You need only use a small amount in or around your houseplants, vegetables and flowers. The miracles of the earthworm are easily seen in the beautiful growth and yields of your plants. The nutrients in our earthworm castings are plentiful. Most importantly, these nutrients are perfectly balanced in two forms. One form can be immediately absorbed by the plant as if it were directly injected and the other is able to provide nutrition which slowly feeds the plant for long periods of time. This soil builder is very cost effective because small amounts provide incredible results and last a long time.

## Features

- Organic fertilizer - pure earthworm castings
- Excellent for houseplants, vegetables, flowers and more
- Non-toxic and odor free
- Just a handful will make your plants happy

## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome Stuff.
            
*by H***G on February 10, 2015*

Great for my organic vegetable garden.  Along with other organic amendments, I grew grape tomato plants that were in the range of 14 feet high.  Attached are some pictures.  There were thousands of grape tomatoes from 3 plants.  You can see that I didn't expect this kind of growth because I kept having to add tomato cages on top of tomato cages.  Then, I had to add some poles to hold them up.  After the growing season ended, I took a pictures of all the cages and supports.
  

### ⭐⭐⭐⭐⭐ Organic pest control!
            
*by N***E on November 12, 2017*

I read about the value of adding worm castings to minimize damage from pests. I'm amazed! Not one of my roses had aphids on it this year. I mixed it in with the soil I use for my lettuces, and then did a small lettuce container without it. The small lettuce container was filled to the brim with whitefly, but the crop with this product was virtually pest-free.While worm castings are rich in nitrogen, I would never use them as a single source of nitrogen. Will it add organic material and micronutrients to your soil? Yes! That's always a good thing. But it shouldn't be your single source of fertilizer.I like to work this into the soil as best as I can and then top with a layer of mulch. For containers, I just mix it in well with the potting mix. You want this to get to the roots of your plants so they'll absorb the chemical that kills insects. I'm interested to see if this will help with fungus gnats since I always seem to be cursed with a fresh bag of potting mix that contains nothing but gnats...The price is expensive, but it beats buying and spraying pesticides, no matter how organic they may be. I'm an inherently lazy gardener so something I can just add to the soil that will keep large infestations at bay is worth the price. I bought two 30-lbs bags this year for our very old orange tree so we'll see if it helps with that as well.
  

### ⭐ Came with bugs
            
*by D***. on January 9, 2019*

I'm just now getting to use this soil I ordered and once i used it i had bugs eating and damaging my plants (indoor garden) I've never had this promblem before but after a week of using this soil i lost several plants and trying to save the rest I have.
