5.0 out of 5 stars Perfect compliment to any organic-fertilizing regimine!
By RKJ on July 19, 2015
I have a decently-sized container garden on my patio, and these crab shells have been the savior I needed for many of my plants. Before I started using crab shells, many of my plants struggled to stay green through the entire growing season and would often produce damaged or low-quality yields (blossom-end rot on squash, little tomatoes, etc.). These crab shells offer a slow-release source of nutrients (especially calcium) that are key to container garden success.

Container plants need good holistic fertilizing that incorporates all of the range of nature's nutrients. This is a great way to add more than simple high-nitrogen to your organic garden.

Yes, this is real ground-up crabshells so there is a fishy smell. If you don't want it to linger on your hands, wear gloves when applying. There will be a fishy smell around your plants too, but that will entirely dissipate in a day or two.
