Plant growth refers to the process by which plants develop and expand. This can include both natural growth, such as that resulting from sunlight or water, as well as intentional cultivation through techniques like pruning, fertilizing, and pest control. Plant growth is influenced by a variety of factors including genetics, environmental conditions, and the presence of beneficial microorganisms in the soil. Understanding plant growth is important for gardeners, farmers, and scientists alike as it helps to optimize crop yields, improve plant health, and develop new varieties of plants.
