Muscadine grape · Vitis rotundifolia

How do I fix root rot in my Muscadine grape?

It is less common for a Muscadine to get root rot unless the soil stays soggy for long periods. Check the drainage of your planting site immediately to see if water is pooling around the roots.

Check these first

  1. Check if the soil feels soggy or swampy.
  2. Inspect the base of the stem for soft or discolored tissue.
  3. Verify that your pot or planting site has adequate drainage holes.

Likely causes

  1. Poor soil drainage

    Most likely

    How to tell: The leaves turn yellow and wilt even when the soil is wet. If you dig down, the roots will look dark, mushy, and smell like decay.

    What to do: Improve drainage by amending the soil with organic matter or creating a raised mound for the vine. If the plant is in a container, ensure it has large drainage holes and use a fast-draining potting mix.

  2. Overwatering

    Possible

    How to tell: The soil surface remains constantly muddy and the vine shows signs of stunted growth. This prevents oxygen from reaching the roots, causing them to suffocate.

    What to do: Allow the top 2 inches of soil to dry out completely before watering again. Adjust your schedule to water every 7 to 10 days rather than daily.

When to worry

If the roots are black and slimy, the plant is likely beyond saving. It is normal for the soil to be damp after a heavy rain, but it should not stay saturated for days.

Stopping it coming back

Always plant in well-draining soil and never let the vine sit in standing water.

Questions people ask

Can I save a vine with root rot?
If the damage is mild, you can trim away the mushy roots and repot the vine in fresh, dry soil. If the majority of the root system is decayed, it is usually best to start over.
Does mulch cause root rot?
Mulch is helpful, but do not pile it directly against the stem. Keep the mulch a few inches away from the trunk to allow for airflow.
