FAQs

Since 2019, FOTMW has researched the benefits of adding wood ash to our local forests. The first thing we did with the ash donations was to test the ash chemical composition. The laboratory studies indicate that Muskoka ash is 25-30% calcium plus smaller amounts of other key plant nutrients, including potassium, magnesium and phosphorus.

Working with three universities, we have applied over nine tonnes of processed wood ash to three sugar maple bushes and our research forest at Camp Big Canoe. Results have been very positive. We have seen that wood ash neutralizes the acidity of Muskoka soil which has been damaged by decades of acid rain. Preliminary research suggests that ash application to the soil increases tree vitality and growth, meaning that trees are more storm-resistant and have the potential to capture more carbon! We are also studying potential changes that may help mitigate spring flooding.

We worked with community volunteer scientists to expand our understanding of the benefits of residential wood ash. Donated, filtered, and mixed ash was distributed along with instructional kits to nearly 80 people across Muskoka. These community volunteer scientists monitor trees on their property for at least one year to assess improvements in overall health metrics, with a select number of participants sending us foliage and soil samples for chemical analysis at Trent University.

Because of the Provincial regulations that apply to residential wood ash, Friends of the Muskoka Watershed staff are not permitted to pick up or transport ash from private residences. Ash can only be accepted at the Rosewarne Transfer Station on Ash Drive days. However, we can provide you with an extra bucket or two for storage. Contact us at friends@fotmw.org.

📌 Our next ash drive is Saturday, November 22 from 9 a.m. to 1 p.m. at the Bracebridge Transfer Station, 1065 Rosewarne Drive in Bracebridge. The 2026 dates so far are Jan. 17, Feb. 21, March 28 and April 19.

We ask volunteers to provide us with wood ash for use in our research, but you may choose instead to sprinkle ash on your own property. Restoration is another important component of FOTMW’s work.

• Only use clean ash. Do not burn metallic foil, plastic products, pressure-treated wood, construction waste or wood that may contain chemical preservatives, insecticides, glue, nails, staples, other metals or paint.
• Allow your wood ash to cool completely – for several days before using. Hot ash is a real fire risk to homes, property and forests.
• Keep your ash dry until you are ready to spread it.
• Wear a mask, gloves and long clothing when spreading ash.
• Spread it in a location that you can keep people and pets away from for a couple of days.
• Sprinkle the ash thinly, about one 750 gram plastic yogurt container over one square metre. (That is equivalent to 4 tonnes per hectare).
• Only apply ash to each location once. Research suggests that one application is enough to replace 50 years of calcium depletion caused by acid rain. (It is not an annual thing like fertilizer)
• Avoid spreading ash over the snow, on a steep slope, or near surface water.
