Step-by-Step Growing Guide
Oregano is a Mediterranean perennial that thrives on neglect — poor, dry, well-drained soil in full sun produces the most intensely flavored, aromatic leaves. Overly rich or moist soil dilutes the essential oils that give oregano its character. Start from seed (slow, 7–14 days at 21°C) or, better, from divisions or stem cuttings. Transplant into soil with pH 6.0–8.0 — it tolerates alkalinity better than most herbs. Space plants 30–45cm apart. No regular fertilizing needed; a light compost top-dress in spring is sufficient. Water deeply but infrequently once established — every 7–10 days in summer; drought stress concentrates the flavor compounds. Cut plants back by one-half to two-thirds in early spring before new growth emerges to prevent woodiness and keep plants bushy. In cold climates, mulch roots after first frost. Divide clumps every 3–4 years to maintain vigor.
