How to Fertilize Trees: A Simple Guide
Understanding the Root System:
Most of the tree’s absorbing roots are located under the canopy, extending beyond the drip line, not at the trunk’s base.
Assessing the Need for Fertilization:
Soil Test: Determine which nutrients your tree needs.
Observation: Look for signs of nutrient deficiency like discolored leaves or slow growth.
Choosing the Right Fertilizer:
Type: Use a slow-release, granular fertilizer.
Formula: Opt for a balanced N-P-K ratio unless otherwise suggested by soil tests.
Applying Fertilizer:
Where: Apply fertilizer under the tree’s canopy, extending just beyond the drip line.
How:
Broadcast Method: Spread fertilizer evenly over the root zone.
Fertilizer Wells: Create shallow wells around the drip line for deeper penetration.
Watering: Water the area thoroughly after fertilizing, but avoid letting water pool around the trunk.
Additional Tips:
Avoid watering the tree trunk directly.
Ensure good soil drainage to prevent root rot.
Water more frequently in hot weather, but avoid overwatering.
