Black tupelo · Nyssa sylvatica

Why is my Nyssa sylvatica suffering from root rot?

It is less common for a Nyssa sylvatica to get root rot, as this tree actually prefers moist soil. This issue usually happens if the tree is planted in heavy clay that does not drain or if the area stays flooded for long periods.

Check these first

  1. Check the soil drainage in the planting site.
  2. Feel the soil moisture 3 inches down.
  3. Inspect the base of the trunk for soft or mushy bark.

Likely causes

  1. Poor drainage

    Most likely

    How to tell: The soil stays soggy for days after rain and the tree shows yellowing leaves or stunted growth.

    What to do: Improve the soil structure by adding organic matter like compost. If the tree is in a low spot, consider installing a drain or mounding the soil to elevate the root ball.

  2. Overwatering

    Possible

    How to tell: The soil surface remains wet to the touch for more than two weeks during the growing season.

    What to do: Check the soil moisture before adding more water. Only water if the top 2 to 3 inches of soil feel dry to the touch.

When to worry

If the leaves are wilting while the soil is soaking wet, the roots may already be failing. This is serious and requires immediate drainage correction.

Stopping it coming back

Ensure the tree is planted in a location with well draining soil and avoid planting in areas that hold standing water.
