🍂 Yellow Leaves

Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle. Unless brand new leaves are turning yellow or all the leaves change color at once, it’s likely just your plant retiring old leaves.

If it seems like there’s a problem, the most likely cause of yellow leaves in Marsh Pennywort is underwatering. The leaves may also appear to be curling or drooping. Yellow leaves can less often be caused by overwatering, nutrient deficiencies, or pests.

Give your plant a good drink and it should perk back up and download Greg to make sure your plant never goes thirsty again!

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
