Is apple cider vinegar harmful for plants?
Apple cider vinegar contains acetic acid, so its antimicrobial properties make it an effective fungicide—as long as you get the dilution rates right. Too much will damage your plants and too little will be ineffective,” warns Lucie Bradley, gardening and greenhouse expert from Easy Garden Irrigation. Household vinegar or distilled white vinegar, the kind you keep in your kitchen to cook with, is typically a 4 to 6 percent acetic acid concentration in water. This solution will kill tender young plants, but older weeds will need a higher concentration to effectively kill them.A bottle of household vinegar is about a 5-percent concentration. Canada thistle, one of the most tenacious weeds in the world, proved the most susceptible; the 5-percent concentration had a 100-percent kill rate of the perennial’s top growth. The 20-percent concentration can do this in about 2 hours.When utilizing vinegar as an insecticide or repellent, you should always mix it with water, generally at a 50/50 solution. This mixing is necessary because vinegar can damage plants, and furnishings and irritate the skin when used without being diluted.Vinegar and Salt You may pour regular five percent household vinegar directly on weeds. You may also mix the vinegar with salt and liquid dish soap for super weed fighting power. Mix one gallon of white vinegar with one cup of salt and mix in a tablespoon of liquid dish soap.
Which plants like apple cider vinegar?

Too much will damage your plants and too little will be ineffective,” warns Lucie Bradley, gardening and greenhouse expert from Easy Garden Irrigation.Soil Chemistry: Vinegar’s high acidity can alter soil pH, making it unsuitable for many plants and soil organisms. This disruption can negatively affect soil structure, nutrient availability, and overall ecosystem balance. Soil Organisms: The acidic nature of vinegar can harm all living things within the microbiome.Acetic acid is a terrific weed killer but it is also a terrific plant killer! Acetic acid works by drawing all of the moisture out of the weed or plant leaf. It is quick to work and it would be common to see a weed or plant brown up after only a few hours of having vinegar applied to its leaves in the full sun.
Can you put vinegar in potted plants?
Vinegar as a fertilizer: Nope, doesn’t work. Acetic acid only contains carbon hydrogen and oxygen – stuff the plant can get from the air. The other things that may be in vinegar could be good for a plant – but it seems an expensive method of applying an unknown amount of nutrition. Spraying vinegar directly on vegetable plants has little benefit and, if applied incorrectly, can do more harm than good. Avoid overuse in gardens, which can cause a rapid drop in soil pH, raising soil acidity, impacting beneficial soil organisms, and causing soil imbalance.Do not apply vinegar too close to your plants, as it can temporarily change soil pH and be harmful to the roots.

Vinegar is used broadly to control insects and other pests and could kill other living things in the treated area such as earthworms, fungi, beneficial bacteria, and insects. These organisms play vital roles in a healthy soil system and without them, soils degrade at rapid rates.How long does vinegar stay active in soil? Occasional use of household vinegar is no longer active in the soil after a few days. Repeated use of vinegar with higher percentages of acetic acid, such as horticultural vinegar, may remain in the soil for several weeks.
