FAQ

Is Ecoworm Potassium Soap safe for edible crops?

Ecoworm Potassium Soap is certified organic by OF&G and biodegradable. It can be used for washing and caring for vegetables, herbs, salads and fruiting plants in gardens and greenhouses. Avoid spraying directly onto edible parts and always rinse produce thoroughly before consumption.

Why is there a 5-day withdrawal period before harvesting?

We recommend allowing 5 days between the final application and harvesting edible crops to minimise soap residue on edible surfaces. Always rinse produce thoroughly before consumption.

Can it be used on all plants?

Ecoworm Potassium Soap is suitable for most flowering and edible plants. However, some sensitive species may react under extreme heat (above 32°C) or if the plant is dehydrated.

Always apply when plants are well watered. To test tolerance, spray a small amount on one leaf and wait 24–48 hours. If no browning or spotting appears, continue with the rest of the plant.

Why do you recommend not spraying directly on fruits or vegetables?

Potassium Soap is designed for washing and caring for leaves and stems. Spraying directly onto fruits or vegetables may leave a light soap residue on delicate produce.

For best results, focus application on leaves and stems, avoid direct contact with edible parts and rinse crops before harvesting or eating.

Can it be used on tomatoes, strawberries or peppers?

Yes. Ecoworm Potassium Soap can be used for plant care on fruit-bearing plants including tomatoes, strawberries and peppers. Apply to the leaves and stems rather than directly onto the fruit to minimise visible residue.
