Parsley as an ‘Energy Vampire’: Which Plants Don’t Suit It Neighbors

Mixed planting remains a popular method in modern gardening. It not only increases the yield and resilience of plants against pests and diseases but also effectively utilizes available space. However, not all plants combine well in the same bed. Some crops may hinder each other, negatively affecting the development of their neighbors.

Why Can Parsley Harm Other Plants?
Agronomy experts recommend placing parsley separately from other crops, as it can suppress growth when planted near certain plants. The most issues arise when parsley is adjacent to lettuce, as it inhibits its development, as well as with dill and other members of the Apiaceae family, such as celery, lovage, and carrots. This is due to the fact that all these plants share common pests and diseases, and their proximity can facilitate the spread of illnesses.
“The most problematic is the proximity of parsley to lettuce. Although both crops belong to the leafy greens, parsley suppresses the growth of lettuce. It is also not recommended to sow it near dill and other members of the Apiaceae family, such as celery, lovage, or carrots. All these crops share common pests and diseases, so their proximity can contribute to the spread of illnesses.”
Which Plants Can Be Planted Next to Parsley?
Despite its potential aggressiveness, parsley can be a beneficial neighbor for certain crops. It pairs well with cucumbers, promoting their healthy growth when planted along the rows and adding dill between them. This combination helps create a stable ecosystem and protects plants from pests.
Another effective option is planting parsley alongside tomatoes. Like basil, it repels pests and helps protect the fruits from diseases, making this symbiosis advantageous for gardeners.
