Can I eat the plant if it has spots?

Only if you are sure it is wild carrot. It looks very similar to deadly plants such as poison hemlock, so do not eat any part unless you have identified it with certainty. If it is correctly identified, the root is generally safe to eat, but you should wash it thoroughly. Avoid eating leaves that are heavily covered in fungus.

Will the spots kill my wild carrot?

Usually not, but it can weaken the plant and reduce root growth. Treat it early to keep the plant healthy.

Wild Carrot: spots, causes and fixes

Check these first

Inspect the leaves for a dusty white coating.
Check if the plant is crowded by other weeds.
Look for dark spots with yellow halos.

Likely causes

Powdery Mildew
Most likely
How to tell: You will see a white, powdery coating on the foliage that looks like flour. It often starts on older leaves and spreads quickly in damp conditions.
What to do: Remove the most heavily infected leaves to stop the spread. Improve air circulation around the plant by thinning out nearby weeds or crowded stems. Avoid overhead watering to keep the leaves dry.
Cercospora Leaf Spot
Possible
How to tell: These appear as small, dark brown or black spots with a lighter center. They often have a yellow halo around them.
What to do: Prune away affected foliage immediately and dispose of it in the trash, not your compost. Ensure you are watering at the base of the plant to keep the leaves dry.

When to worry

If the spots cover most of the foliage, the plant will struggle to photosynthesize. It is normal to see a few spots on older leaves at the end of the season.

Stopping it coming back

Provide plenty of space between plants for good airflow and water only at the soil level.
