Name one factor that affects plant growth in landscapes.

Soil quality is a fundamental factor that affects plant growth in landscapes due to its role in providing essential nutrients, water retention, and proper drainage. Healthy soil contains a balanced mixture of minerals, organic matter, air, and water, which are crucial for the optimal growth of plants. The pH level of the soil and its texture can influence nutrient availability; for instance, sandy soils drain quickly but may lack the nutrients that clay soils can provide. Additionally, microbial activity in the soil contributes to nutrient cycling and overall plant health. Therefore, ensuring good soil quality is essential for creating and maintaining healthy landscapes, making it a significant factor affecting plant growth.
