Works better than most fertilizers

Until I'm brave enough to start my own worm bin, I buy these. The price has increased about $2 from last year. These earthworm castings work better than most fertilizers that I've purchased. I don't have to remember what plants needs what - these are good for ALL of my plants! It's easy to make your own tea - add some castings to a cheesecloth bag, or even a tea bag; submerge in water and wait for the water to turn brown. Sometimes I squeeze the excess water from the bag directly into the water. I use the water whenever I water my plants - giving them a dose of good nutrition! These worm castings have an earthy smell and do NOT stink, and I have not found a worm in them (a bit sad about that :) ) . Good for the garden and soil health = sometimes I sprinkle them castings on top of the soil and then water in.

Great plant boost and seed starting addition

These earthworm castings are great. I usually add some to my seed starting mix and add a little into plants I'm potting up and it always seems to give them a little boost. It's great for transplanting into raised garden beds, too. After awhile, you'll often get earthworms from the eggs hatching there, which is a boon to the plants in the raised beds and pots. I've gotten to like the small bags it comes in, as well. They're easier to store and move around my potting area than the larger bag of the brand I used to get. Of course, I would figure that bulk packaging is better for the environment, but the smaller bags are a bit better on my back these days. There is no odor to it (and I have a very sensitive sense of smell) and there shouldn't be. It's always nice and dry in the bag.
