Plant spraying: as a preventive tool use every fortnight, especially leading up to time when you would normally see pests. If you have seen pests, apply every 3-4 days until you see the pest numbers recede. The treatment should be repeated, because if even one pest escapes, the infestation can start all over.
Spray thoroughly to upper and lower leaf surfaces, including under the leaf axils, where pests tend to congregate. Apply early morning or late evening.

Do not apply in full sun or on a windy, rainy day, as the soap will dry out/run off and will not be as effective.

Surface cleaning: spray on the surface, leave for 1-3min and clean with a brush or cloth. Rinse the surface with water.



Can it be used on all plants?

The fatty acids used in the soap are specifically chosen to be effective against insect pests while being the least toxic possible to plants. Still, some plants may be damaged in extreme conditions, such as temperatures over 32ºC or when the plant is severely dehydrated. Apply Potassium Soap only when the plant has been watered and is well-hydrated. Wilted plants are more susceptible to damage.

If you’re concerned that a plant may be sensitive to soap, apply a small amount to one leaf. You’ll know in about a day if the leaf shows spotting, browning, or other signs of damage.
