How to Prune Oregano

Origanum vulgare

Reviewed by Kiersten Rankel M.S.

Quick Answer

Cut oregano back by about one-third in late spring just before or at the start of flowering, which is when the leaves carry the most flavor. Harvest throughout the growing season by snipping stems back to a set of healthy leaves, and cut the whole plant down to a few inches in fall or after flowering to prevent excessive woodiness. Never cut into the very base of old woody stems, since oregano needs some established wood to regenerate.

When is the best time to prune?

Oregano's pruning window opens with warm weather and closes before hard frost, so the exact months shift several weeks earlier or later depending on your region's spring temperatures.

Why Should I Prune My Oregano?

Oregano is a cut-and-come-again herb, meaning the more you harvest and trim it, the bushier and more productive it becomes. Without regular pruning it sends up tall flowering stalks, turns woody at the base, and the leaves become smaller and less flavorful.

The best time for a major cutback is in late spring just as flower buds form but before they fully open. The essential oils that give oregano its flavor are most concentrated at this stage. Cut stems back to about one-third of their length, leaving at least two to three sets of leaves on each stem.

For ongoing harvests throughout summer, simply snip stems back to just above a leaf pair. New shoots will sprout from each cut point, keeping the plant dense and leafy.

In fall, cut the whole plant back to 2-3 inches from the ground. This prevents the plant from going entirely woody over winter and encourages fresh growth the following spring. In colder zones this also helps the crown survive the cold.

Know Before You Cut

Difficulty Easy

Max removal 1/3 of stem length per harvest; cut to 2-3 inches in fall

Growth pattern Upright mounding herb

Tools Sharp scissors or pruners

What Should I Remove?

Cut stems back to a leaf pair, not bare stem

Harvest regularly throughout the growing season

Remove flowering stalks to keep leaves flavorful

Cut back hard to 2-3 inches in fall before frost

Don't cut below all the leaves into bare woody stem

Don't let flowering go to seed if you want flavorful leaves

Don't skip the fall cutback or stems get excessively woody

How Do I Prune Step by Step?

Time your main prune for late spring

Wait until stems are about 6-8 inches long and you can see small flower buds forming. This is when flavor is strongest and the plant responds best to pruning.

Find a leaf pair and cut just above it

Locate a pair of healthy leaves partway down each stem. Cut the stem at a slight angle just above that pair of leaves. New growth will sprout from those leaf nodes.

Remove any flower stalks

If flowering stalks have already appeared, cut them back to where they branch from a leafy stem. Removing flowers redirects energy back into leaf production.

Do a fall cutback before first frost

In late summer or early fall, cut the entire plant back to about 2-3 inches above the soil, leaving a small stubble of stems with the lowest leaf buds intact.

Got More Questions?

Can I harvest oregano any time of year?

You can harvest throughout the growing season, but flavor peaks just before the plant flowers. In cold climates, harvesting stops when frost arrives. In mild climates oregano can be harvested almost year-round.

I cut my oregano too far back and now it looks like bare sticks. Will it come back?

If there are still some green leaf buds or small leaves at the base of the stems, the plant will very likely push new growth. If the stems are completely bare and brown with no green, recovery is uncertain. Water regularly and give it two to three weeks to see any response.

My oregano has flowered and gone to seed. Should I cut it now?

Yes. Cut the flowered stems back to a healthy set of leaves. The plant will send out fresh leafy growth and you will get a second harvest of flavorful leaves before fall.

Do I need to prune oregano if I'm growing it indoors?

Yes. Indoor oregano needs regular snipping to stay bushy. Without harvesting or tip pruning, it will get leggy and sparse. Snip stem tips back to a leaf pair every few weeks.
