Why is it essential to understand soil pH before planting a tree?

Understanding soil pH is crucial before planting a tree because it directly influences nutrient availability in the soil. Soil pH affects the chemical forms of nutrients and their solubility, which in turn determines how easily plants can absorb these nutrients. For example, certain nutrients such as nitrogen, phosphorus, and potassium are more available to plants at specific pH levels. If the pH is too high (alkaline) or too low (acidic), plants may struggle to access the nutrients they need for healthy growth and development.

Effective nutrient uptake is vital for a tree’s overall health, impacting everything from foliage growth to root development and resilience against diseases. Therefore, knowing the soil pH can guide the selection of tree species that will thrive in that particular environment and influence how to amend the soil to meet the needs of the planned planting.
