I’ll make this super simple. I found a recipe for a DIY kelp extract on Buildasoil, credit to Coot and Silva. You can find it here.

You’re probably asking, why are you making this post? Well, there was some math involved and I thought I’d share this to make this technique a lot easier.

I’m using a Chameleon Hose-End Sprayer and using the 8 ounce to 1 gallon dilution ratio for this tutorial.

In basic terms, DIY foliar kelp extract = 2 tsp kelp meal / 1 gallon of water. We are using 8 ounces per gallon dilution, so there are 128 ounces in a gallon, so that mean 8 ounces fits into 1 gallon a total of 16 times. That means we need to make a 16 times strength kelp solution to make this work. It will not burn the plants using it this way because it is being re-diluted at the same rate coming out of the hose end sprayer if you do it right.

I dont know about you, but I dont need to make 16 gallons of foliar spray that I have to use that same day. The Chameleons sprayer chamber holds 32 ounces of liquid, we’re only going to need 8 tsp of DIY kelp extract for that 32 ounces of water, and that is going to give you a total of 4 gallons of spray coming out of the sprayer if you use the 8 ounce per gallon dilution setting.

You’ll need to strain the kelp water through a paint strainer or compost tea bag before putting it in the sprayer chamber.

An even better option is to use the Chapin Concrete Sprayer, but some people arent ballers.

Thanks, cT.
