Does lemon juice affect plant growth?

Lemon juice contains citric acid, which is an organic acid that can affect plant growth. Citric acid can lower the pH of the soil, making it more acidic. Most garden plants prefer soil with a pH between 6.0 and 7.0. If the soil is too acidic, it can make it difficult for plants to absorb nutrients from the soil, which can lead to stunted growth and other problems.

Lemon juice can also directly damage plant tissue. The citric acid in lemon juice can cause leaves to wilt and turn brown, and it can also damage the roots of plants. If you are using lemon juice on plants, it is important to dilute it with water and to use it sparingly.

In some cases, lemon juice can be beneficial to plants. For example, lemon juice can be used to clean the leaves of plants and to remove pests. However, it is important to use lemon juice in moderation, as it can damage plants if it is used too much.
