Cantaloupe companion plants
Cantaloupe (*Cucumis melo* var. *cantalupensis*) is fully dependent on insect pollinators for fruit set. Per UC IPM, like other cucurbits, cantaloupe produces separate male and female flowers on the same vine, and pollen transfer by bees is required for fruit development. Female flowers are.
Cantaloupe (Cucumis melo var. cantalupensis) is fully dependent on insect pollinators for fruit set. Per UC IPM, like other cucurbits, cantaloupe produces separate male and female flowers on the same vine, and pollen transfer by bees is required for fruit development. Female flowers are receptive for only one day. A cold snap, rain event, or pesticide application that suppresses bee activity during that day means no fruit.
Companion planting for cantaloupe should therefore prioritize pollinator retention above all other goals.

The companion planting table
| Plant | Role | Friend / Foe / Neutral | Notes |
|---|---|---|---|
| Borage (Borago officinalis) | Premier bee attractor; continuous bloom | Friend | Plant 2–3 weeks before transplanting melons |
| Sweet alyssum (Lobularia maritima) | Syrphid fly attractor; aphid predator support | Friend | Low-growing; use at bed edges |
| Basil (Ocimum basilicum) | Some aphid deterrence; attracts pollinators when in flower | Friend | Trim to delay bolting |
| Nasturtium (Tropaeolum majus) | Aphid trap crop; pollinator attractor | Friend | Monitor and remove infested plants |
| Dill (Anethum graveolens) | Attracts Braconid wasps when in flower | Friend | Place on north side to avoid shading |
| French marigold (Tagetes patula) | Beneficial insect habitat; potential nematode suppression | Friend | Best in paths between beds |
| Radish | Early-season space crop; possible cucumber beetle deterrence | Friend (tentative) | Harvest before vine sprawl |
| Sunflower | Attracts pollinators; provides north-side windbreak | Neutral | Keep 36+ inches from melon crown |
| Corn | No documented benefit; potential shading risk | Neutral | Not recommended near melons |
| Fennel | Allelopathic to cucurbits | Foe | Separate entirely |
| Other cucurbits (cucumber, squash) | Shared cucumber beetle host; amplifies pest load | Foe (concentrated) | Spread cucurbit crops across the garden |
| Potatoes | Shares soilborne pathogens; no companion benefit | Foe | Keep separate in crop rotation |
