Cucumbers are excellent companion plants because they benefit from pollinators and can share space with many vegetables, herbs, and flowers.
🥒 Best Companion Plants for Cucumbers
🌼 Flowers
Marigolds – Help deter aphids, beetles, and nematodes.
Nasturtiums – Act as a trap crop for aphids and cucumber beetles.
Sunflowers – Can serve as a natural trellis for smaller cucumber varieties.

Texas Zone 8b Tip ☀️
In hot climates like Dallas:
Plant cucumbers in spring (March–April) or late summer (August).
Provide afternoon shade during extreme heat.
Keep soil consistently moist with mulch.
Harvest frequently to encourage more production.
One of my favorite combinations is cucumbers + nasturtiums + dill + zinnias. It’s beautiful, attracts pollinators, and helps keep cucumber pests in check while producing plenty of cucumbers. 🥒🌼🐝🌿
