Yes it has some very beneficial uses around the garden and Bonsai. Oh, also very nice on chips and a fried egg 🙂
Grow beautiful azaleas: Occasionally water plants with a mixture of two tablespoons vinegar to one quart water. Azaleas love acidic soil.
Kill grass on walks and driveways.
Pour full strength on unwanted grass.
Kill weeds. Spray full strength on growth until plants have starved.
Increase soil acidity. In hard water areas, add a cup of vinegar to a gallon of tap water for watering acid loving plants like rhododendrons, gardenias, or azaleas. The vinegar will release iron in the soil for the plants to use.
Freshen cut flowers. Add 2 tablespoons vinegar and 1 teaspoon sugar for each quart of water.
Prolong the life of flowers in a vase. Add two tablespoons of vinegar plus three tablespoons of sugar per quart of warm water. Stems should be in three to four inches of water.
Neutralise garden lime. Rinse your hands liberally with vinegar after working with garden lime to avoid rough and flaking skin.
Clean pots before repotting, rinse with vinegar to remove excess lime.
