Great for all the plants!

A little goes a long way and I do wrap it in a bag and store in cool fridge to keep it from damage. Great for all plants I own, roses and some peppers!

great product, not so great smell.. lol

I like that is is easy to use. it's a great organic fertilizer. the only bad thing about it is the odor that comes from the fish and seaweed. but there's not much to complain about because it serves a great purpose

I've used fish fertilizer in the past with good results. This King Neptune brand combines fish protein and seaweed. I use one tablespoon per gallon jug. It is a good organic tonic that does not harm the environment. Tomatoes respond well.
