Parsley Is Turning Yellow – That May Be the Cause

Parsley turns yellow: The wrong location

The location of the parsley is an important factor. She doesn’t like it too warm and sunny.

• Find a partially shaded location. The soil should be loose.
• Parsley is incompatible with itself. At the location of your parsley, there should not have been any umbellifers for at least three years. These include, for example, carrots, dill, celery, and fennel.
• If you grow these plants in the same bed for consecutive years, there is a risk that soil pests and fungi will multiply and the parsley will turn yellow.

Water and fertilize parsley properly

Watering the parsley is quite problematic. The herb must not be too dry, nor does it tolerate too much moisture. The plant does not like waterlogging at all.

• A permeable soil is best so that the water can run off.
• Use your finger to check that the top layer of soil is dry. Water only then and don’t give too much water.
• Yellow leaves are also often a result of magnesium deficiency. You can fix this with magnesium fertilizer.

Soil pests and fungal spores as triggers for yellow leaves

Various soil pests such as root aphids, nematodes, maggots, and fungal spores feel extremely comfortable on the roots of parsley. These pests are usually not visible to the naked eye.

• If you want to sow your parsley in the garden immediately and not in pots, it is best to wait until August. Pests and fungal spores then hardly spread and you get stronger plants.
• If your parsley often turns yellow in the garden, you should have the soil examined for fungi and pests. You should not use contaminated soil as potting soil for your kitchen herbs on the balcony or window sill.
