Fish fertilizer is a common organic fertilizer that is recommended for both houseplants and the garden. It has a strong following and its proponents feel that it is better than any other type of fertilizer, but how does it really stack up against the most common organic fertilizer; compost?
Fish fertilizer – are the accolades true, or a bit fishy?
I always thought that fish fertilizer was an acceptable product. As a nitrogen source it is very over priced as explained in Fish Fertilizer – Is It Worth Buying? but at least the fertilizer is being made from a resource that is a waste product, namely fish guts (offal) , bones and heads. It seemed like a good use for this waste product.
But a comment left on my other post, by Cynthia E. Olen, June 12, 2016 made me rethink things. Thank you Cynthia.
Did you know that companies are harvesting whole fish to make the fertilizer? I didn’t believe it myself, but is is true.
Fish fertilizer is very popular. It is reported to be a good source of nutrients and a good source of proteins, amino acids and oils – for your plants. Can plants use fish proteins and oils? Is fish fertilizer a good source of nutrients?
Before I go any further let me say that there is nothing wrong with using fish fertilizer. It will help make your plants grow. I have two problems with fish fertilizer; it is extremely expensive compared to other sources of fertilizer and many of the claims for it have no basis.
