How to use: Add 1 teaspoons per litre of water. Use as a foliar spray or root drench every 2–4 weeks. A little goes a long way.
Early season tip: Spray around the base of plants and on lower leaves in early spring to discourage insects and fungal spores before they settle in.
Note: In stronger doses, wood vinegar can act as a natural herbicide. Keep it diluted and avoid spraying directly on tender leaves or young seedlings.
