Plants that thrive in acidic soils such as rhododendrons, azaleas and gardenias will benefit from the use of apple-cider vinegar as fertilizer. Acid-loving plants need soil with a pH level of 4.0 to 5.0 to thrive. The pH, or level of acid and alkaline in the soil, is important, as it determines the amount of hydrogen the plants will receive. You can increase the acidity in soil and fertilize plants with apple-cider vinegar in your garden and feed cut flowers to keep them fresh longer.
Combine 1 cup of apple-cider vinegar with 1 gallon of warm water in the watering can. Pour the mixture over the plant soil to increase the iron level and acidity of the soil.
Mix 1 cup of vinegar and 1/2 gallon of water in a bucket. Mix 1 cup of sugar and 1/2 gallon of water in another bucket. Combine both mixtures in the plastic container with sprayer. Spray the plants with the vinegar and sugar mixture to increase plant nutrients.
Add 2 tbsp. of sugar and 2 tbsp. of vinegar to the water in a vase of fresh-cut gardenias or other flowers that grow in a low pH environment. According to The Vinegar Institute, this solution keeps your cut flowers fresh for a longer period.
