11 Best Plants to Attract Beneficial Insects

1. Lavender (Lavandula spp.)

Lavender attracts:
🌼 🐝 Bees, 🦋 Butterflies, 🐞 Ladybugs

• Light: Full sun is ideal for lavender, requiring at least 6 hours of direct sunlight daily.
• Water: Let the soil dry out somewhat between watering. Lavender is drought-tolerant and prefers not to be overwatered.
• Soil: Well-draining, sandy or rocky soil with a neutral to slightly alkaline pH.
• Fertilizer: Minimal fertilization needed. If necessary, use a light application of a balanced, slow-release fertilizer in early spring.
• Common Problems: Root rot from overwatering, fungal diseases in humid conditions.
• Propagation: Best propagated by cuttings in the summer.

2. Marigold (Tagetes spp.)

Marigolds attract: 🐝 Hoverflies, 🐞 Ladybugs, 🦋 Butterflies

• Light: Full sun to ensure healthy growth and maximum flowering.
• Water: Water regularly, allowing the soil to dry out slightly between watering sessions.
• Soil: Adaptable to most soil types but prefers well-draining soil.
• Fertilizer: Apply a balanced, slow-release fertilizer at planting time; over-fertilization can reduce flowering.
• Common Problems: Susceptible to powdery mildew and spider mites. Proper spacing and airflow can reduce these issues.
• Propagation: Easily grown from seeds sown directly in the garden in spring.

3. Sunflower (Helianthus annuus)

3. Sunflower (Helianthus annuus)

Sunflowers attract: 🐝 Bees, 🦋 Butterflies, 🐞 Ladybugs, 🪲 Beetles (predatory kinds too!)

• Light: Full sun is crucial for sunflowers, requiring 6 to 8 hours of direct sunlight daily.
• Water: Keep the soil moist, especially during growth and flowering stages.
• Soil: Prefers well-draining, fertile soil but can tolerate poor soil conditions.
• Fertilizer: A balanced fertilizer can be applied once at planting. Too much nitrogen can delay flowering.
• Common Problems: Susceptible to fungal diseases and pests like aphids and beetles. Rotation and good sanitation can help manage these issues.
• Propagation: Direct seed in the garden after the last frost date.

4. Yarrow (Achillea millefolium)

Yarrow attracts: 🐞 Ladybugs, 🪰 Hoverflies, 🦟 Parasitic Wasps

• Light: Thrives in full sun but can tolerate partial shade.
• Water: Drought-tolerant once established. Water during prolonged dry spells.
• Soil: Prefers well-drained soil; can tolerate poor soil conditions.
• Fertilizer: Generally does not require fertilization. If soil is very poor, a light application of balanced fertilizer in spring can help.
• Common Problems: Can become invasive if not managed. Susceptible to powdery mildew in humid conditions.
• Propagation: Propagate by division in spring or fall. Seeds can also be sown directly in the garden.

5. Cosmos (Cosmos bipinnatus)
