Cucumbers

Cucumbers and parsley are both moisture-loving plants that need plenty of water to produce a good crop. If you plant cucumbers too close to parsley, the cucumbers will use up all the water in the soil, leaving the parsley to dry out.

Beans

Beans and parsley are both nitrogen-fixing plants that add nitrogen to the soil. If you plant beans too close to parsley, the beans will use up all the nitrogen in the soil, leaving the parsley to suffer.

Peas

Peas and parsley are both legumes that need a lot of nitrogen to produce a good crop. If you plant peas too close to parsley, the peas will use up all the nitrogen in the soil, leaving the parsley to starve.

Radishes

Garlic

Garlic is a strong-smelling herb that is known for its antibacterial and antifungal properties. It also contains a compound called allicin, which is toxic to some plants. If you plant garlic too close to parsley, the allicin in the garlic can damage the parsley plants and stunt their growth.

Carrot rust flies are a common pest of carrots, but they can also damage parsley. These flies lay their eggs on carrot foliage, and the larvae feed on the leaves, causing them to turn yellow and wilt. Carrot rust flies can be controlled by using insecticides, but it is best to avoid planting carrots and parsley near each other to prevent this problem.

Cabbage loopers are another pest that can damage parsley. These caterpillars feed on the leaves of parsley, causing them to become ragged and torn. Cabbage loopers can be controlled by using insecticides or by hand-picking them off of the plants.

Aphids are small, sap-sucking insects that can damage a variety of plants, including parsley. Aphids feed on the leaves of parsley, causing them to become yellow and wilted. Aphids can be controlled by using insecticides or by spraying the plants with a water-and-soap solution.

Slugs and snails are also pests that can damage parsley. These creatures feed on the leaves of parsley, causing them to become ragged and chewed. Slugs and snails can be controlled by using slug bait or by hand-picking them off of the plants.

By avoiding planting parsley near plants that attract pests, you can help to protect your parsley plants from damage. If you do notice any pests on your parsley plants, you can use the following methods to control them:

  • Insecticides can be used to kill pests on contact.
