Prof. Samuel Fitzgerald, Ph.D.When planting parsley, it's important to choose its neighbors wisely to avoid growth problems and maximize your garden's health. Some plants are aggressive and will compete directly for the same growing space or even attract the wrong pests and diseases. In this article, I'll discuss what not to plant near parsley. Choosing the right companion plants for parsley helps create the best garden possible.
Carrots
- Root competition: Both seek same soil nutrients
- Pest sharing: Attract similar destructive insects
- Space conflict: Mature roots tangle underground
Dill
- Chemical inhibition: Releases growth-slowing compounds
- Cross-pollination: Creates inferior hybrid seeds
- Height conflict: Tall dill shades parsley plants
Resource competition is what causes all the trouble with bad companions. Carrots and parsley are at war with each other over nitrogen and phosphorus. Lettuce makes incessant demands for moisture, leaving parsley's soil dry. Dill exudes chemicals through its roots, which have the effect of slowing the growth of Chinese parsley. All these struggles reduce the number of leaves.
Compatible Plants provide advantages for both plants in the partnership. For example, tomatoes create cool areas beneath them on hot sunny days. Onions naturally deter aphids and root maggots; they also work with asparagus to provide resources to one another efficiently. Plant tomatoes, onions, and asparagus at least 12 to 18 inches (30 to 45 cm.) away from parsley to avoid overcrowding.
Nothing can be more bewildering than arranging a garden layout with companion plants. However, certain plants should be placed in sunny beds, while others should be positioned in shadier areas. Carrots dislike dill, and onions are excellent pest barriers when grown along the garden borders. Try to arrange for your parsley to be planted in a different location in the garden every year.
*Apply these "companion principles" of planting. Be mindful of plant compatibility charts before you plant side by side. Check on the distance you should allow between diverse species. Check for pest issues weekly. Your parsley will be stronger and healthier, your harvest abundant all season long!*
