What not to plant with dill

Carrots: in the same family (carrot family), so it shares pests and diseases and belongs in a different bed in the crop rotation.

What the evidence says

Companion planting charts come from long garden experience, and most pairs have never been tried in a replicated trial. Several extension services say so directly; one review gives traditional charts more entertainment than scientific value.

What reliably helps dill: the right planting dates, enough space, and moving crops to a new bed each year (crop rotation).

Questions

What can I plant with dill?

The traditional companions are cantaloupe, cucumbers, eggplant, garlic, green onions, head lettuce, leaf lettuce, onions and 5 more listed above. Plant companions in neighbouring rows or squares rather than in the same hole.

What should not be planted with dill?

The guides keep carrots apart from dill. Give it a different bed, especially the crops from the same family, which share pests and diseases.

Does companion planting with dill work?

Most pairings are tradition rather than tested results: extension services call companion planting promising but largely unproven. None of the pairs for this crop has been tested in a trial we could find. Good spacing, sun, water and rotation do more for a harvest than any single pairing.

How close can cantaloupe grow to dill?

In a raised bed planted by the square foot, give dill 1 per sq ft and cantaloupe 1 per 4 sq ft, in neighbouring squares. In rows, dill needs 12 in between plants.
