Check these first

- Feel the soil 2 inches deep to see if it is soggy.
- Smell the soil for any signs of decay.
Likely causes
Overwatering
Most likelyHow to tell: The plant looks wilted despite the soil being wet, and the stems near the base may turn mushy or dark. You might also notice a sour or swampy smell coming from the soil.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the plant does not perk up, gently remove it from the pot to inspect the roots and trim away any black or slimy sections with sterilized scissors.
Poor Drainage
Most likelyHow to tell: Water sits on the surface of the soil for a long time after watering, or the pot lacks holes at the bottom. The soil stays heavy and dense instead of feeling light and airy.
What to do: Repot your vervain into a container with plenty of drainage holes using a well-draining potting mix. Add perlite or coarse sand to the soil to improve aeration and prevent future water buildup.

When to worry
If the stems are turning black and mushy at the base, the rot has likely spread too far to save the plant. It is time to act as soon as you notice the plant wilting while the soil is still damp.
Stopping it coming back
Always empty the saucer under your pot after watering so the plant never sits in standing water. Ensure your soil mix is loose enough to allow excess water to flow through quickly.
