Why are my marsh cudweed leaves curling? Causes and fixes

Check these first

Touch the soil to see if it feels dry.
Check the location to see if the plant is getting too much intense afternoon heat.
Inspect the undersides of the leaves for any signs of pests.

Likely causes

Underwatering
Most likely
How to tell: The leaves will feel dry or crispy and start to curl inward as the plant loses turgor pressure. The soil surface will feel dry to the touch.
What to do: Water your plant immediately until liquid drains from the bottom. Maintain a schedule of watering every 2 to 4 days to ensure the soil stays consistently damp.
Heat Stress
Possible
How to tell: The leaves curl during the hottest part of the day when the plant cannot keep up with evaporation. The foliage may look slightly wilted even if the soil is damp.
What to do: Move the plant to a spot with slightly more afternoon shade if temperatures exceed 85 degrees. Ensure the soil remains moist to help the plant cool itself through transpiration.
