Asparagus is a perennial vegetable that benefits greatly from companion planting. Choosing the right plants to grow alongside asparagus can enhance its growth, help control pests, and improve soil health. Here are some excellent plants to consider for planting with asparagus.
Beneficial Companions
- Tomatoes (Solanum lycopersicum)
- Benefits: Tomatoes release solanine, which helps repel asparagus beetles, while asparagus helps repel nematodes that can harm tomatoes.
- Conditions: Both prefer full sun and well-drained soil.
- Basil (Ocimum basilicum)
- Benefits: Basil repels pests like aphids, mosquitoes, and tomato hornworms. It also improves the growth and flavor of tomatoes.
- Conditions: Prefers full sun and well-drained soil.
- Parsley (Petroselinum crispum)
- Benefits: Parsley attracts beneficial insects like hoverflies and predatory wasps, which help control pests.
- Conditions: Prefers full sun to partial shade and well-drained soil.
- Marigolds (Tagetes spp.)
- Benefits: Marigolds repel nematodes and beetles, making them a great companion for asparagus.
- Conditions: Prefer full sun and well-drained soil.
- Comfrey (Symphytum officinale)
- Benefits: Comfrey’s deep roots mine nutrients from the soil, making them available to shallower-rooted plants like asparagus. Its leaves can be used as a nutrient-rich mulch.
- Conditions: Prefers partial shade to full sun and moist, well-drained soil.
- Coriander (Coriandrum sativum)
- Benefits: Also known as cilantro, coriander attracts beneficial insects and repels harmful pests.
- Conditions: Prefers full sun to partial shade and well-drained soil.
Ground Covers
- Strawberries (Fragaria × ananassa)
- Benefits: Strawberries serve as a ground cover, reducing weed competition and helping to retain soil moisture.
- Conditions: Prefer full sun and well-drained soil.
- Oregano (Origanum vulgare)
- Benefits: Oregano acts as a ground cover and repels pests with its aromatic leaves. It also attracts beneficial insects.
- Conditions: Prefers full sun and well-drained soil.
Nitrogen-Fixing Plants
- Legumes (Beans and Peas)
- Benefits: Legumes fix nitrogen in the soil, improving fertility and benefiting asparagus. Plant bush beans or peas to avoid competition for space.
- Conditions: Prefer full sun and well-drained soil.
Flowers
- Nasturtiums (Tropaeolum spp.)
- Benefits: Nasturtiums attract beneficial insects and repel pests like aphids. They also act as a trap crop, drawing pests away from more vulnerable plants.
- Conditions: Prefer full sun and well-drained soil.
- Chives (Allium schoenoprasum)
- Benefits: Chives help repel aphids and other pests while attracting pollinators.
- Conditions: Prefer full sun to partial shade and well-drained soil.
Tips for Planting Companions
- Consider Growth Habits: Ensure companion plants do not compete for light or nutrients. Taller plants can provide shade for sun-sensitive companions.
- Plan for Seasons: Asparagus is a perennial that remains in place for many years. Plan annual companions that can be rotated in and out without disturbing the asparagus crowns.
- Maintain Spacing: Adequate spacing helps prevent overcrowding and allows each plant to thrive. Asparagus requires ample space for its ferns to grow.
- Mulch Wisely: Use organic mulch to retain moisture, suppress weeds, and provide nutrients. Comfrey leaves make an excellent mulch for asparagus beds.
