Is white vinegar good for gardenias?
It is fine to use diluted vinegar on your gardenias. The Vinegar Institute recommends using diluted vinegar on gardenias (also azaleas and rhododendrons) in hard water areas at a rate of 1 cup of vinegar to a gallon of tap water (see here). The vinegar will help to release iron in the soil.
What kind of vinegar do you use for gardenias?
Though vinegar can be fatal to many common plants, others, like rhododendrons, hydrangeas and gardenias, thrive on acidity which makes a bit of vinegar the best pick-me-up. 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.

Will white vinegar make soil acidic?
Vinegar is a diluted, liquid form of acetic acid, so adding it to soil naturally lowers the soil’s pH and increases its acidity. The pH of an average, commercially manufactured white vinegar, like that sold in supermarkets, is 2.4, making it highly acidic.
Are gardenias acid loving plants?
Taking Care of Gardenia & Growing Gardenia Plants Gardenias require bright, indirect light. They also need moist, well-drained, acidic soil for optimal growth.
What causes yellowing of gardenia leaves?
The most likely reason for yellow leaves on gardenias is low iron. Gardenias need acidic soil, which means soil with a pH between 5.0 and 6.5. This pH range makes iron in the soil available to gardenias. If the pH of your soil is outside those numbers, you can adjust it by adding an acidic fertilizer.
Does vinegar kill plants?
Apple cider vinegar and other types of vinegar kill plants by drying out their top growth. Vinegar will not kill the roots, so some weeds will regrow after treatment. Weeds or plants that have leaves covered by a waxy cuticle do not readily absorb vinegar and so may not be killed.
Do gardenias like acidic soil?
Gardenias prefer acidic soil with a pH around 5.5. Some fertilizers, like blood meal, cottonseed meal and fish emulsion, can help acidify soil and maintain a low soil pH. These fertilizers for acid-loving plants are the best choice for gardenias.
Gardenias, like azaleas, are acid-loving plants. They will not thrive on general-purpose fertilizers; instead, they require special formulas higher in acid. Commercial mixtures can be supplemented with other acidic materials such as coffee grounds, tea or Epsom salts .
