I am looking for a good organic fertilizer to use for house plants. I read that a fertilizer is organic if the NPK ratio when added up is less than 15 and no one number in the ratio is higher than 10 - so for instance a ratio of 5-8-10 would not be considered organic because the total is 23 which is higher than 15.
Anyhow, I bought one the other day that was 5-1-1 I think but the labels said it merely is "organic-based" so I'm not confident that it is entirely organic, though maybe it is. Can anyone recommend a good truly organic one - I'd like to be able to fertilize my house plants without adding any chemicals whatsoever. Thank you.
