Likely causes
Root rot
Most likelyHow to tell: The entire plant looks wilted even when the soil is damp. The base of the stem may look discolored or feel soft.
What to do: Dig around the base to inspect the roots, which should be firm and light colored. If they are black and slimy, the plant is likely beyond saving, so remove it to prevent spreading soil pathogens.
Extreme heat stress
PossibleHow to tell: The plant wilts slightly during the hottest part of the day but perks up by evening. This is a natural reaction to intense sun.
What to do: Ensure the plant is established with a deep root system by watering deeply but infrequently. Do not add extra water during the day, as this can shock the plant.

Questions people ask
- Does my buckwheat need more water when it droops?
- Not necessarily. If the soil is already wet, adding more water will only make the root rot worse.
- Can I stake my drooping buckwheat?
- Staking is not recommended for this plant. It is better to address the underlying issue with the roots or soil drainage.
