Onions can deter aphids, a pest that may affect safflower, and their strong scent can confuse other pests.
Calendula officinalis
pot marigold
Calendula officinalis
Pot Marigolds attract beneficial insects that can help control pests that might feed on safflower. They also add visual appeal.
Centaurea cyanus
Cornflower
Centaurea cyanus

Cornflowers have similar water and nutrient needs and can compete for resources, potentially reducing safflower yield.

Helianthus annuus
Common Sunflower
Helianthus annuus

Sunflowers have similar resource needs, especially for sunlight and nutrients, and could outcompete safflower in these areas.

Aphids

Small, sap-sucking insects that can infest stems, leaves, and flowers. Symptoms include stunted growth, yellowing leaves, and the presence of sticky honeydew.

Lygus Bugs

These bugs feed on developing seeds, causing shriveled or deformed seeds, and reducing the yield.

Steps:

    • Sow seeds directly into well-drained soil after the last frost.
    • Plant seeds about 1 inch deep and space them 6-12 inches apart.
    • Water the seeds gently after planting.
    • Thin seedlings to the desired spacing once they emerge.

Neem Oil

Effective against aphids and other common pests, acting as a natural insecticide.

Insecticidal Soap

Can be used to control aphids and other soft-bodied insects.

Compost

Improves soil quality, drainage, and provides essential nutrients for healthy growth.
