How to Grow Oreganos UK | Regional Planting Calendar
Move through the SoilCommander growing library like a course: keep the navigation in place, open the next lesson, and build your garden plan step by step.
In the UK, oreganos go in the ground early March to early April.
Oreganos (Origanum vulgare) — perennial.
Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from early March in Southern England to early March in Scotland.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.
RHS recommends propagation by seed or division in autumn or spring; a single spring window is applied uniformly across all four sub-regions since RHS gives no UK-region-specific gradient.

When to pick: Harvest oregano leaves as required from late spring through to autumn. Flavour peaks before flowers open (RHS); optimal leaf flavor occurs just before flowering (NC State)
Storage
Leaves used fresh or dried by hanging sprigs in a dark, well-ventilated space for several weeks (RHS)
A perennial with aromatic foliage and pollinator-attracting flowers, valuable for wildlife gardens and culinary use. Native to Europe and North Africa. Hardiness H6 (hardy in all of UK and northern Europe, -20 to -15C). Full sun or partial shade. Soil: chalk, loam or sand; well-drained, preferably alkaline; neutral to alkaline pH; protect from winter waterlogging, which causes root rot. Height and spread 0.5-1m. Time to maturity 2-5 years. Propagated by seed or division in autumn or spring. Cut back old, flowered stems in early spring. Generally pest-free (some varieties susceptible to leafhoppers) and generally disease-free.
Tier 1. RHS factsheet on glasshouse red spider mite (two-spotted spider mite), naming tomato and strawberry among the host plants affected under glass or in a polytunnel.
Directly fetched and verified. RHS explicitly does not recommend pesticide use against aphids; recommends tolerance, manual squashing, and encouraging/purchasing natural predators (ladybirds, hoverflies, lacewings, parasitoid wasps, earwigs) as biological control, especially under glass.
