Fertilizing Sunburst Locust Tree: Local Soil Test Beats Generic Advice

Reader Question: Best Fertilizer for Sunburst Locust? Pale Leaves, Forgot Previous Product.

"Some leaves pale/immature. Fertilized years ago with great results but forgot what. Recommendation?"

Fertilizer choice depends on your soil pH, organic matter, and existing nutrient levels. A product that worked once may be wrong now.

Visit a local garden center/nursery.
Ask for a tree fertilizer suited to your area and species.
Espoma Tree-tone (granular) is a reliable organic option: 1–2 cupfuls spread under canopy, water in.
Apply now (early spring) for best uptake.

If pale leaves persist after fertilizing, get a soil test—chlorosis often signals high pH (iron/manganese lockup), not nitrogen lack.
