How can I effectively use peat moss to improve the growth of my tomato plants?

To effectively use peat moss to improve the growth of tomato plants, mix it into the soil before planting to improve moisture retention and aeration. Peat moss can also help balance the pH level of the soil, providing a better environment for tomato plants to thrive. Additionally, regularly adding a layer of peat moss on top of the soil can help retain moisture and nutrients, promoting healthy growth.
