What is Companion Planting?

Companion planting is the practice of placing specific plants together that live in harmony and benefit each other. There are a few different mechanisms in place that make improved growth and health a positive outcome.

Benefits of companion planting:

Companion planting also allows for closer plant spacing, which is great for those with limited garden space. Making the most of every square inch is always a win in my book!

The 5 BEST Dill Companion Plants

Dill is an excellent friend to have in the garden because it draws in predatory insects that will feed on the pests in your garden. It also attracts those lovely pollinators. Woo hoo! Let’s discuss the 5 best dill companion plants:

#1: Brassicas

The brassica family includes vegetables like cabbage, broccoli, kale, and cauliflower. This group is commonly plagued by the cabbage worm and aphids, causing extensive to its leaves. Dill is an effective companion plant to this family by attracting predatory insects to keep these pests at bay.

A study published in 2016 showed a 1.6-fold increase in predatory insects when using dill companion plants with a crop of kale. Not bad! *Of note, Marigolds took the cake with a 3.1-fold increase – throw a few of those in the garden as well!

#2: Squash

Squash can commonly become overrun with the pesky squash bug, but there is a solution! Do you know what LOVES to eat squash bugs? Parasitic wasps! One of the best ways to draw parasitic wasps in is to use dill companion planting – they love dill once it starts to bloom!

#3: Cucumber

Since cucumber and dill go together like peas and carrots (hello dill pickles!), it only makes sense that they’re friends in the garden as well. Cucumber beetles are a serious threat in the garden and guess what dill does to help out? It attracts the 2 main insects that LOVE to feast on cucumber beetles:

#4: Asparagus

While asparagus doesn’t necessarily benefit dill, the assistance goes the other way. Dill can be a HUGE help for asparagus, which is a sensitive plant that is often plagued with pests. Here’s what dill can do to help:

  • Release aromatic compounds that repel pests
  • Attract beneficial pollinators (especially the swallowtail butterfly!)
  • Attract beneficial predatory insects
  • Has a shallow root system, so unlikely to disrupt the deep (and sensitive) asparagus crowns

#5: Nasturtiums

The beautiful (and edible!) nasturtiums are a very common companion plant – benefiting most any plant out there!  Dill already does a great job attracting beneficial pollinators and predator insects, so we may as well double our efforts by adding in some nasturtiums as well. 

  • Attract beneficial pollinators
  • Attract beneficial predatory insects
  • Can be used as a trap crop to keep the pests off of your other vegetables
  • Provides a living mulch to reduce weed pressure and moisture loss

2 Plants to AVOID Planting Near Dill

Dill has a few enemies in the gardening world, so it’s best to leave these 3 vegetables away from your section of dill.

#1: Apiaceae family

The Apiaceae family includes things like carrots, fennel, caraway, and cilantro. Not all family members get along! It’s best to separate members of the Apiacea family. They attract similar pests, which can lead to a significant infestation. Secondly, some members can cross-pollinate with each other, resulting in funky combinations.

#2: Tomato

While some people like to use tomatoes as companion plants for dill due to their ability to deter pests, it’s not the best pairing overall. Once dill matures, it can actually inhibit the growth of tomato plants (and other nightshades). If you chose to plant tomatoes and dill together, pull the dill plants out before they mature.
