What is the main reason for applying mulch around plants?

Mulching around plants serves multiple purposes, but one of the significant benefits is protecting plants from extreme temperatures. When mulch is applied, it acts as a thermal blanket for the soil, which can help to insulate roots during colder months. This insulation is crucial as it helps maintain a more stable soil temperature, reducing the risk of freeze damage to plants.

In addition to temperature regulation, mulch also plays a key role in moisture retention and weed suppression, creating a healthier environment for plants. While enhancing soil nutrients and improving drainage are important factors in soil health, they are not the primary reason for applying mulch specifically. By keeping the soil warmer and protecting the plant's root systems, mulch contributes greatly to the overall health and survival of plants during varying weather conditions.
