What does vinegar do to rosemary plants?

Rosemary plants are generally tolerant of a wide range of pH levels in the soil, but they do prefer slightly acidic conditions. Vinegar is a mild acid, so it can help to lower the pH of the soil and make it more suitable for rosemary plants. However, it's important to use vinegar sparingly, as too much can damage the plant.

Here are some tips for using vinegar on rosemary plants:

- Use a 50/50 mixture of vinegar and water.

- Apply the mixture directly to the soil around the base of the plant, avoiding the leaves and stems.

- Water the plant thoroughly after applying the vinegar and water mixture.

- Repeat the application every 4-6 weeks, or as needed.

Vinegar can also be used to repel pests and diseases from rosemary plants. For example, you can spray a mixture of 1 tablespoon vinegar and 1 cup water on the leaves and stems of the plant to help deter aphids and other insects.

Overall, vinegar can be a helpful tool for maintaining healthy rosemary plants, but it's important to use it in moderation. Too much vinegar can damage the plant, so be sure to follow the directions provided.
