Oregano is the herb that gets better when you dry it. Fresh oregano is mild and green; dried oregano is punchy, warm and intensely savoury — which is why the main harvest is a drying harvest, taken just before the flowers open when the leaves are at their most aromatic. It is a hardy, drought-tolerant perennial that spreads steadily, so a small patch will give you a generous annual harvest with very little work.

Oregano takes 80–90 days to mature, according to the Garden Grove crop data. It is a hardy herb in the Lamiaceae family with low water needs. For the full growing picture, see our growing guide for oregano, and use the Harvest Date Calculator to work out your picking window from your sowing date.

Signs oregano is ready to pick

Oregano is ready for its main harvest when the stems are about eight to twelve inches tall and the flower buds are forming at the tips but have not yet opened. At this stage the leaves are at their most flavourful, with a strong, warm scent when you brush them. The leaves should be dark green and plentiful along the stems, with no yellowing at the base.

Once the small white or pink flowers open, the leaves are still usable but the flavour starts to decline, and the plant's energy shifts to flowering and seed. If you miss the bud stage, harvest anyway — oregano picked in flower is still far better than no oregano — but aim for the bud stage for the best drying harvest. Avoid picking from stems that are woody and leafless at the base.

How to pick oregano

Cut oregano stems with clean scissors or secateurs, snipping each stem about two inches above the ground or just above a leaf node. Take the whole stem — leaves, buds and all — because you will dry the stems and strip the leaves afterwards. Work across the whole patch, taking up to half the stems at the main harvest, and leave the rest to flower for the bees.

Harvest in the morning after the dew has dried, when the leaves are dry and the oils are concentrated. Do not wash the stems before drying — brush off any soil instead, because wet leaves dry slowly and can go mouldy. If you only need a few leaves for cooking, snip the tips of a few stems rather than cutting whole stems. For the full growing picture, see our growing guide for oregano.

The best time of day to harvest

Harvest oregano in the morning, after the dew has dried but before the sun gets hot. That is when the leaves are dry, crisp and most aromatic, because the essential oils are at their most concentrated after a cool night. Leaves picked in the afternoon heat are often limp and less flavourful, and wet leaves picked while the dew is still on them dry slowly and can go mouldy in storage.

Choose a dry day for harvesting if you can, and avoid picking after rain, when the foliage is wet and heavy. If you must pick on a damp day, spread the cuttings out in a single layer in a ventilated spot for an hour before you bundle or bag them. And get the harvest out of the sun straight away — a basket of cut herbs left in the sun for an hour will wilt and lose much of its aroma. Morning picking is a small habit that makes a real difference to flavour and keeping quality.

How often to pick

Oregano is a pick-little-and-often crop, and regular picking is part of good plant care, not just a way to get a harvest. Once the plant is established, you can take a small picking every week or two through the growing season, always leaving enough growth for the plant to recover. Each cut encourages the plant to branch and push out fresh, tender growth, so a plant that is picked regularly stays bushy and productive far longer than one that is left alone.

Do not wait for a single big harvest unless the plant is one you cut whole for drying — for most herbs, steady, small pickings give you better flavour and a healthier plant. Take a few sprigs from several plants rather than a large handful from one, and always leave at least two-thirds of the plant intact. If you go away for a few weeks, ask someone to pick the herbs, or cut the plant back before you leave so it regrows while you are gone.

What happens if oregano is left too long

Oregano left unpicked flowers, sets seed and then dies back at the stem tips, leaving woody, leafless stems and fewer leaves for the next harvest. The leaves that remain after flowering are still usable, but they are less aromatic, and the plant's growth slows as it puts energy into seed. An uncut patch also spreads by seed and by runners, and can become a tangled mat of woody stems.

If your oregano has flowered and gone woody, cut the whole patch back to a few inches above the ground after flowering — it will regrow with fresh, leafy stems within a few weeks. Dry the cut stems even if they have flowered, because the leaves are still useful in cooking. The best prevention is the main harvest itself: cut the stems just before flowering each year, and the plant will stay young and productive.

How to store oregano

Drying is the best way to store oregano, and dried oregano is stronger than fresh, so a little goes a long way. Tie the cut stems into small bunches and hang them upside down in a warm, dark, well-ventilated spot for one to two weeks, until the leaves are crisp and crumble easily. Strip the leaves into a jar, discard the stems, and store the jar in a dark cupboard. Use the Herb Drying Calculator for timing.

Fresh oregano keeps for one to two weeks in the fridge, wrapped loosely in a damp tea towel inside a bag. You can also freeze it, but freezing is unnecessary when drying works so well. Dried oregano keeps its flavour for six to twelve months, though it is at its best in the first few months. Crush the leaves just before using them to release the most flavour.

Succession and continuous harvest tips

Oregano is a hardy perennial with low water needs, so there is no need to sow it every year — a single plant will spread and supply you for years. The plant dies back in winter in cold climates and regrows from the roots in spring. Every few years, divide the clump in spring to keep it vigorous, and replant the divisions in fresh soil.

The harvest rhythm is simple: take light pickings of fresh leaves through spring, take the main cutting harvest just before flowering in early summer, and then let the plant regrow for a second, smaller harvest in late summer. After the second harvest, leave the plant alone so it can harden off before winter. A plant that is cut regularly stays dense and leafy; one that is never cut becomes woody and sparse.

Frequently asked questions

When is oregano ready to harvest?

When stems are eight to twelve inches tall and flower buds are forming but not yet open, typically 80–90 days from sowing. That is when flavour peaks.

Should I dry oregano or use it fresh?

Dry it — dried oregano is stronger and more flavourful than fresh. Hang small bunches upside down until crisp, then strip the leaves into a jar.

How much oregano can I cut at once?

Up to half the stems at the main harvest. Cut stems about two inches above the ground and leave the rest to flower for the bees.

Will oregano come back next year?

Yes, it is a hardy perennial. It dies back in cold winters and regrows from the roots in spring.

Why does my oregano taste weak?

It may have been picked after flowering, or grown in rich, wet soil. Pick before flowering, and grow it in poor, well-drained soil in full sun.
