🌱 Tree Mallow

Sow in spring (or early autumn in mild areas). For best germination, lightly scarify or soak seed 8–12 hours. Sow 5–10 mm deep in free-draining compost at ~18–21°C; keep evenly moist but not waterlogged. Pot on seedlings to avoid root check and harden off before planting out after the last frost. Direct sow into a weed-free bed in late spring, thinning to final spacing.

Usually self-supporting in sheltered sites, but tall stems can flop or snap in wind. Stake young plants with a stout cane and soft ties, or grow against a fence/wall in exposed gardens; keep ties loose and check through the season.

Leaves and/or flowers are commonly prepared as a soothing tea. Use about 1–2 tsp dried material per cup, steep 10–15 minutes; a cool or cold infusion can be preferred when aiming to retain more mucilage. Traditionally sipped for throat irritation or used as a gargle; the cooled tea may also be used as a gentle wash for irritated skin. Stop use if sensitivity occurs and do not use as a substitute for medical care.

Cut back hard in early spring to encourage strong new flowering shoots (reduce stems to 30–60 cm and remove dead/weak wood); deadhead during summer to prolong flowering.
