Asparagus Companion Plants

Asparagus is a long-lived perennial vegetable, so its dedicated bed needs careful planning before planting. Young crowns take time to establish and should not be treated like a spare annual bed. Some short-lived companions can occupy edges initially, but avoid anything that requires digging. Reliable results come chiefly from weed control, drainage and patience.

Good companions for Asparagus

PlantWhy it helps
ParsleyParsley can occupy the edge of an established asparagus bed without deep cultivation, provided it does not crowd emerging spears.
French marigoldsCompact French marigolds add flowers near the border and can be removed easily without disturbing perennial asparagus crowns.
Pot marigoldsCalendula is a short-lived, shallow-rooted edge plant that brings colour while leaving the central bed accessible.
NasturtiumsNasturtiums can trail along the outside of an asparagus bed, where they do not interfere with spear harvesting.
StrawberriesSome gardeners use strawberries at an asparagus bed edge, but only where there is ample room and good airflow.
BasilBasil can be grown as a nearby annual in warm weather, rather than planted where it would disturb crowns.

Keep Asparagus away from

PlantWhy to separate them
GarlicAnnual garlic planting and lifting disturb soil, whereas asparagus crowns need a permanent bed with minimal cultivation.
PotatoesPotato digging and earthing up can damage asparagus roots and make it difficult to maintain a weed-free bed.
PumpkinsTheir large leaves and sprawling stems shade the bed, hinder spear picking and compete for water and space.

Tips

Plant one-year crowns in spring, about 45 cm apart in a permanent sunny bed with well-drained, organic-matter-rich soil. Keep the bed thoroughly weeded and do not harvest heavily for the first two seasons. Thereafter, cut spears only during the established spring picking period, then let ferny growth feed the crowns through summer.
