Question of the Week
I don't use a wood stove anymore where I had ashes for my garden. Do you know of a gardening supplement from Bonide or another brand that would substitute?
One of the best substitutes for wood ashes as far as nutrient content would be Espoma Greensand. This product provides potassium, magnesium, iron, silica and can contain as many as 30 other trace minerals. These are some of the nutrients that are found in the wood ashes. Another good substitute that is high in potassium is Espoma Kelp Meal.
If you were using the wood ashes to raise the pH of acidic soil in addition to its nutrient value, I would also use Espoma Garden Lime. It is important to test your soil pH first to determine if your soil needs a pH adjustment.
