🍂 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 shedding old leaves.

Overwatering and root rot are the most likely cause of problems in American Dune Grass, since they are sensitive to wet soil. The leaves may also appear to be curling or drooping. Less often, yellow leaves are caused by underwatering, nutrient deficiencies, or pests.

Replace soggy soil with fresh, dry soil and download Greg to make sure your plant never gets overwatered again!

🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

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.
