Rue and Basil Separation Distance: Preventing Cross-Pollination

Rue (Ruta graveolens) and basil (Ocimum basilicum) are alleged poor companions. The real issue: pollinators crossing them.

Recommended Separation

30+ feet between plantings reduces bee/butterfly cross-visitation significantly.

Better Strategy: Prevent Flowering

• Basil: pinch all flower buds (cut 3 leaf pairs below). Extends leaf harvest.
• Rue: ornamental; flowers attract beneficials. Allow if not near basil.

Companion Planting Reality

Allelopathy (chemical inhibition) between rue/basil is unproven. Most "companion" claims lack rigorous evidence. Focus on:

• Same cultural needs (sun, water, soil).
• Physical spacing for airflow.
• Pollinator management if seed saving.

If saving basil seed, isolate variety by 150+ feet or bag flowers. Rue seed not typically saved.
