Black tupelo · Nyssa sylvatica

Why are my Nyssa sylvatica leaves turning yellow?

It is less common for this tree to have yellow leaves, which usually happens due to soil pH issues or poor drainage. Check your soil moisture and acidity levels first.

Check these first

  1. Test the soil pH level with a home kit.
  2. Check the soil moisture at a depth of 3 inches.
  3. Inspect the drainage of the planting site.

Likely causes

  1. High Soil pH

    Possible

    How to tell: The leaves turn yellow while the veins remain green, a condition known as chlorosis. This occurs because the tree cannot absorb iron from alkaline soil.

    What to do: Test your soil pH and aim for a range of 5.5 to 6.5. Apply elemental sulfur or an iron chelate supplement to the soil to lower the pH and improve nutrient uptake.

  2. Overwatering

    Possible

    How to tell: The leaves turn yellow and may feel soft or mushy. This happens when the roots sit in waterlogged soil for too long.

    What to do: Check that your planting site has good drainage. Adjust your watering schedule to every 7 to 14 days, ensuring the soil stays moist but never swampy.

When to worry

Be concerned if the yellowing spreads rapidly across the entire canopy. It is normal to see some yellowing in late autumn as the tree prepares for its natural leaf drop.

Stopping it coming back

Maintain consistent soil moisture and keep the soil slightly acidic to prevent nutrient deficiencies.

Questions people ask

Will my tree recover from yellow leaves?
Yes, if you correct the soil pH or drainage issues, the tree will grow healthy green leaves in the next season.
Can I use regular fertilizer to fix yellow leaves?
No, standard fertilizer may not address the underlying pH issue. Focus on soil amendments that specifically target iron availability.
