Is short, shallow, and frequent irrigation considered better than long, deep, infrequent irrigation?

Long, deep, infrequent irrigation is generally considered more beneficial for trees compared to short, shallow, and frequent watering. This approach encourages deeper root growth, allowing trees to access moisture from deeper soil layers. When irrigation is shallow and frequent, tree roots tend to remain near the soil surface, which can lead to several issues, such as reduced drought tolerance and increased vulnerability to stress.

Deep watering promotes healthy root systems because roots will grow downward in search of water. This also fosters better nutrient uptake and enhances the tree's overall health and resilience. Additionally, deep watering allows for moisture to reach areas of the soil that are not accessible to frequent, shallow watering, ensuring that the entire root zone is adequately moist.

While certain tree species may have different watering requirements, the principle of supporting deep root growth through longer irrigation intervals generally applies to many tree types and soil conditions. Nonetheless, adjusting watering practices based on specific tree species and local soil characteristics can still be important for optimal growth and health.
