- Use grey water within 24 hours of harvesting - if left too long the water can breed bacteria and bad smells.
- Seedlings should NOT receive your grey water - they can't handle the soaps/detergents that might be present.
- Apply your greywater directly to the soil - do not use on root crops or leafy green vegetables where the edible part may come in contact with the water. Grey water is best for fruiting aboveground vegetables (tomatoes, beans, peppers, etc).
- Alternate grey water application with fresh water - the sodium salts from the grey water will raise the pH of the soil over time.
- No more than 1/2 gallon per square foot each week - University of Massachusetts Extension Service also recommends shower or bathtub water being best for your garden, followed by bathroom sink and washing machine. Some sources recommend AGAINST using kitchen sink water because of the food particles and grease residues which can encourage bacterial growth.
