Fish emulsion is excellant and fish emulsion with kelp or seaweed is incredible. Lots of micronutrients that aren't usually available with most fertilizers. You can use it as a foliar feed or drench the growing medium (soil) with it. Just don't use it straight, follow the directions and you'll be quite satisfied.

In the past I simply used Neptune Harvest Fish/Seaweed emulsion which has all minors and an NPK ratio of 2-3-1.

This year I am trying Al's (Tapla) method of mixing a controlled release fertilizer (Osmocote) and a micronutrient product (Micromax) into the potting mix and then using the fish emulsion as needed.

I like the idea of premixing the controlled or slow release stuff in as I think it will even out the boom or bust nature of using water soluble fertilizers alone with container plants and provide more consistent nutrient availability.

Yes, I forgot to mention that I did that, too, Justaguy- I added a bit of slow-release fert to my mix. The emulsion I have, though, is just 5-1-1. It seems a little one-sided to me, except my slow release stuff I already added has less N for the ratio. I can't remember what it was exactly though, because I threw the box out. Do you guys know where seaweed might be available? Any other fert suggestions?

Mommie Rose,

The NPK ratio is pretty normal for most fish emulsion products I have seen in stores. The NPK ratio I listed is for Neptune Harvest Fish/Seaweed blend. It's two products in one. Click me to see their products.

Their fish emulsion is 2-4-1 and their fish/seaweed is 2-3-1, but has more of the micros in it due to the seaweed.

It is not inexpensive, but one gallon makes 128 gallons. It is a very popular fertilizer among those who competitively grow giant pumpkins.
