How to grow angelica
Overview
Angelica archangelica is a tall, aromatic biennial herb in the Apiaceae family, prized for its sweet, celery-like stems and seeds used in cooking, confectionery, and herbal medicine. It requires rich, moist soil and part shade to thrive, and will bolt to seed in its second year if not harvested promptly.

Soil Preparation
Angelica prefers deep, rich, loamy soil with a pH of 6.0–7.0. Enrich with well-rotted manure or compost before planting. Ensure good drainage to avoid root rot, but keep soil moisture consistent.
Growing Guide
Sow angelica seed fresh (viability drops quickly) 5 mm deep in moist, rich soil in a part-shade position. Space plants 60 cm apart. Keep soil consistently damp but not waterlogged. In hot weather, mulch roots and water deeply to delay bolting. For leaf harvest, remove flower stalks as they appear in the second year.
Sowing
Sow fresh seed 5 mm deep, 30 cm apart, in seed trays or direct. Germination takes 14–21 days at 15–20°C. Direct sowing is best as seedlings can be sensitive to transplant shock.
Care
Feed with a balanced liquid fertiliser every 4–6 weeks during active growth. Remove flower stalks promptly to prolong leaf harvest. Cut back spent foliage in autumn to reduce pest and disease risk.
Companion Planting
Angelica pairs well with other moisture-loving herbs like mint, lemon balm, and comfrey. Avoid planting near fennel or dill, as they can cross-pollinate and reduce seed purity.
Common Pests & Risks
Aphids and leaf miners are common. Control aphids with a strong water spray or insecticidal soap; remove affected leaves for leaf miners. Slugs may attack young seedlings in damp conditions.
Harvesting
Harvest young, tender stems before flowering in the second year, cutting at ground level. Leaves can be picked from the first year onward; use fresh or dry for later. Seeds are collected when the umbels turn brown and dry.
In the Kitchen
Use young stems candied or in jams, leaves in salads or teas, and seeds as a spice. Store fresh stems in the fridge for a week; dry leaves for longer storage. The flavour is sweet and slightly musky.
Troubleshooting
Yellow leaves: overwatering or poor drainage. Brown leaf edges: heat stress or low humidity. Bolting early: triggered by hot, dry weather or root disturbance. Stunted growth: soil too poor or dry. Seed not germinating: seed too old or stored poorly.
