How to grow lovage
Overview
Lovage is a large, clump-forming perennial herb grown for its intense celery-like flavour in leaves, stems, and seeds. It is a versatile kitchen staple that provides repeated harvests through the growing season and thrives in cooler, moist conditions.
Soil Preparation
Lovage prefers a deep, fertile soil with a pH of 6.0–7.0. Before planting, dig in well-rotted compost or aged manure to improve moisture retention and fertility. Ensure the soil is free-draining to prevent root rot in wet conditions.
Growing Guide
Plant lovage in a position that gets morning sun and afternoon shade, especially in warmer zones. It needs deep, fertile, well-drained soil with plenty of organic matter worked in. Sow seeds 6 mm deep and 30 cm apart, or start in pots and transplant when 10 cm tall. Space plants 60–90 cm apart to allow for their large mature size. Keep soil consistently moist but not waterlogged, and mulch heavily to retain moisture and suppress weeds.
Sowing
Sow lovage seeds 6 mm deep in seed trays or direct in the garden after the last frost. Germination takes 14–21 days at 15–20°C. Transplant seedlings when they have 4–6 true leaves, spacing them 60–90 cm apart. Lovage can also be grown from divisions of established clumps.
Care
Feed lovage with a balanced organic fertiliser in early spring and again after each major harvest. Cut back flower stems to encourage leaf production, and divide clumps every 3–4 years in early spring to maintain vigour. Remove dead leaves in autumn to reduce pest habitat.
Companion Planting
Lovage grows well near brassicas, carrots, and parsnips, as its strong scent may deter some pests. Avoid planting near fennel, which can cross-pollinate and reduce seed quality, and keep away from potatoes as they may compete for nutrients.
Common Pests & Risks
Aphids and leaf miners are the most common pests on lovage in Australia. Control aphids with a strong water spray or insecticidal soap, and remove affected leaves to manage leaf miners. Slugs and snails may damage young shoots in damp weather; use organic pellets or barriers.
Harvesting
Harvest lovage leaves and stems from late spring when they reach 20–30 cm tall, cutting the outer stems at the base. For the best flavour, pick before the plant flowers. You can also harvest seeds when they turn brown in late summer.
In the Kitchen
Use lovage leaves and stems fresh in salads, soups, and stews for a strong celery flavour. The seeds can be used as a spice, similar to celery seed. Lovage leaves dry well for winter use, and the stems can be blanched and frozen.
Troubleshooting
Yellow leaves: usually from overwatering or poor drainage; improve soil and reduce watering. Brown leaf edges: often from hot afternoon sun; move to a shadier spot or increase mulch. Stunted growth: may indicate nutrient deficiency; feed with a balanced fertiliser. Leaf miners: remove affected leaves and use neem oil. Flowering too early: cut back flower stems to extend leaf harvest.
