Fertilizing Ginkgo Trees: What Works and What to Avoid

Ginkgos aren't fertilizer-specialists, but stressed trees need diagnosis before feeding.

Fertilizer Options

• General tree/shrub fertilizers work fine—no need for cycad-specific formulas.
• Epsom salts (magnesium sulfate) are safe if magnesium is deficient.

Critical Warning

Never fertilize a stressed tree. It worsens root damage. First investigate:

• Light green leaves, yellowing old foliage, poor branching = possible nitrogen deficiency.
• Check drainage, sun exposure, root health, pests/diseases.

Best Approach

Resolve underlying stress. Then, if nitrogen is low, apply a balanced slow-release fertilizer in spring.
