Using wood ash is simple, as long as it comes from untreated wood, free of varnishes, dyes, and scraps of paper or cardboard with ink.

Preparation:

• Collect the ash completely cool.

• Sift it through a fine sieve to remove large pieces or charcoal fragments.

• Store it in a dry, airtight container to prevent it from absorbing moisture.

If you want to apply it in liquid form, you can prepare ash water:

1. Add 2 tablespoons of ash per liter of water.

2. Mix well and let it sit for 24 hours.

3. Filter before using to avoid clogging the sprayer or watering can.
