Organic souce for potassium?

I tend to plant almost everything with Black Kow and bone meal which takes care of the Nitrogen and Phosphorus but i don't know a source for the potassium. I am definitely not strictly organic, but i like to start plants off with this when I plant them or first thing in the spring.

Comfrey (wilted leaves or tea), green sand and wood ash are good sources of available postassium. You don't want too much in there just yet though

You can get greensand and a faster-acting form of potassium (potassium sulfate?) from Peaceful Valley Farm Supply. http://www.groworganic.com Virtually everything they sell is certified organic. I think these two products only come in 50-lb sacks, for that is what I have, but I know I'll eventually use it all up. They keep indefinitely, don't smell, and don't attract critters, so if you have space, storing the stuff shouldn't be a problem. PVFS is located in California and shipping cost is based in part on how far the stuff has to go. The cost of shipping to NC might be a real bear, but if you can't find it anywhere else, here it is.

They carry Greensand at Jesse Israel's in 5 pound bags.

Thank you Darius, again.

You just now remembering this thread? LOL!

Kelp Meal is a good source of Potassium and also contributes micro-nutrients.

Also, wood ash is mostly calcium carbonate or calcium oxide, which you don't want to use if you have alkaline soil.

Bananas are a great source of potassium for people. I wonder how pulverized peels would do?

Pins there is even more potasium in the peel than in the fruit meat, so using the peels in your compost or directly in the soil around certain plants is great. I use to bury peels pieces around my roses (back when I grew roses) and always had gorgeous plants.
If you feeze them first and than allow them to thaw they virtually fall apart and are much easier to handle.

What a great idea! Thanks so much for sharing, Rikerbear.
