Is vinegar good for plant growth?
Besides, can I spray apple cider vinegar on my plants?
Take a bottle and combine 1-ounce of apple cider vinegar with 3-ounces of water and mix it together. You can spray this on your plants to keep the aphids off of them, although some plants don't like the acidic nature of apple cider vinegar. It could end up hurting your plants if you spray too much or spray too often.
Keeping this in view, how long does vinegar last in soil?
In concentrations this strong, vinegar becomes hazardous and can cause environmental damage. Vinegar is a contact or "burndown" herbicide, killing what it touches within hours or days. The worst part is that it may looks like it's working, but weeds will then resprout from the roots, particularly perennial species.
Combine one cup of plain white vinegar with a gallon of water and use the next time you water these plants to see some amazing results. You can also add some distilled vinegar to your soil to fight lime or hard water for other not-so-acid-loving plants.
