Answer: The most convenient source of Potash, or potassium, is wood ashes. If you have a wood burning fireplace, you can add the ashes to your garden. Or, you can purchase a bag of potassium at a well stocked nursery - one that carries organic fertilizers. You can purchase Organic Potash (called Palm Bunch Ash 0-0-30) through the online source http://www.planetnatural.com. Another approach is to find a fertilizer with a high level of potassium (the 3 numbers on the fertilizer package indicate the 3 major nutrients, nitrogen, phosphorous and potassium). Choose a fertilizer with a higher third number.
Best wishes with your garden!
