Home made Potassium for flowering

Has anybody worked on making your own flowering blend with ashes. I am looking for some way to test the content and meter it like on the nutrient bottles( 1 tblsp per gal kinda thing). Any help or advise would be appreciated.

I have included a link to the O - state study on the subject http://extension.oregonstate.edu/gardening/wood-ash-can-be-useful-yard-if-used-caution
Re-invent the wheel, people used to make what they needed, that was lost with the industrialization of food. Find it and share. Independence, it's not just another day.

Peace be with you

corn cob ash produces about 5% potassium but its a bitch to make. I suggest chopping it up as fine as you can before burning or cooking.. it will take forever otherwise.personally I just stick with kelp meal, rock dust, neem meal and homemade vermicompost. I also don't have the room for a camp fire either.

feeding worms oatmeal and romaine lettuce alone produces quite a bit of potassium and iron among other minerals.

i m guessin u have a pure, or pure enough source of ashes. also ashes have some unique properties that the other sources dont. i use a firestarter and would nt want to put it(the ashes) straight on plants. the ash does go in my mulch pile however(hypocritical?) i used the banana tea, and the last tea i brewed had some bite sized chunks of banana and coconut water. the plants look happy after that one. picked up lots of good tips here. dont mean to b too hypercritical, organically speaking.

i would often take ashes from my burn pile and add a few handfuls into the planting hole for new ornamentals as its a great source of K to promote root growth.

You can burn just about anything and make ashes in a small area.

Hardwood ashes would be recommended 1st... but you can burn weeds, melon rinds, fruit peels, etc.
A lot of these have HIGH potassium sources, so a little goes a long way.

There are several common global weeds that have high potassium too, nettle, dock, lamb's quarter, knotweed, wild mustard and wild mint to name a few, thistle's too. These can be dried and ground up, like what hyroot was suggesting.
