Lemon thyme combines the aromatic warmth of thyme with a true lemon scent — making it the go-to for fish, chicken, and lemon-forward desserts. The variegated form 'Aureus' (gold-edged leaves) is especially ornamental. Culture identical to English thyme: full sun, lean soil, and excellent drainage.
Harvest before flowering for best flavour. Trim lightly after flowering to maintain a compact habit. Propagate from cuttings or layering in summer.
Thyme Root Rot
Stems blacken at the base, foliage yellows and wilts, and roots turn brown and mushy. Common in heavy or poorly drained soil.
Remove affected plants and avoid replanting thyme in the same spot. Improve drainage with grit or raised beds, and water only when soil is dry.
Mint Rust
Small orange or rust-colored pustules on the undersides of leaves, followed by yellowing, distortion, and leaf drop. Stems may show swelling.
Remove and destroy infected foliage. Avoid overhead watering and improve air circulation. Cut plants to the ground and dispose of debris in severe cases. Do not compost infected material.
Botrytis (grey mould)
Grey fuzzy mould on petals and stems, worst in cool wet conditions.
Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
