How to grow Oregano
Updated October 2026
Oregano, the pizza herb, is a tough, bushy Mediterranean perennial that thrives on sun, heat, drought and lean soil. Greek oregano is the standard culinary type. It is hardy in most of the country, and its summer flowers are covered in bees and butterflies.
📖 Our full guide: How to Grow Oregano
Not to be confused with: Oregano is a close relative of sweet marjoram, which has a milder, sweeter flavor and is less cold hardy.
Where to plant
Plant oregano in full sun in average soil, such as sandy loam, with good drainage and dry to medium moisture. It tolerates heat and drought but rots in wet, poorly drained soil. Golden and variegated types do better with a little shade in the heat of the day.
Avoid rich soil and heavy feeding, which soften the plant and weaken the flavor.
- Most regions: plant in spring; oregano is a hardy perennial in about zones 4 to 8 and returns each year.
- Florida, the Gulf Coast and Hawaii: grow it in raised beds or pots of gritty mix so it stays dry through summer rains, and plant in the cooler months.
- The coldest parts of the Northern Plains and Alaska: mulch over winter or grow it in a pot moved to shelter.
Choosing a variety
Greek oregano (Origanum vulgare subsp. hirtum) is the standard culinary oregano. Many other oreganos are grown mainly as ornamentals, such as golden 'Aureum'. Because seedlings vary in flavor, buy plants or take cuttings from one with good aroma.
How to plant
- Set out plants or rooted cuttings in spring, about 12 inches apart, in full sun.
- Oregano can also be grown from seed; sow on the surface or barely covered, as the seed is tiny.
- Water in, then let the soil dry between waterings.
Watering and feeding
Water sparingly once established and let the soil dry between waterings. Oregano thrives on the dry side and rots in wet ground. It needs little or no fertilizer.
Pruning and care through the year
- Shear plants back regularly before flowering to encourage new leaves and keep them tidy.
- Divide established clumps every few years in spring to refresh them.
- Let some stems flower if you want to feed pollinators; the flowers attract large numbers of bees and butterflies.
Harvesting
Snip leaves as needed. Flavor is best just before the plant flowers, which is the time to cut stems for drying. Hang small bunches in a shady, airy place, then store the leaves in airtight jars.
Growing in pots
Oregano grows well in pots of gritty, free-draining mix, which is the best option in rainy, humid areas. Water only when the mix is dry.
Propagation and saving seed
Take cuttings from plants with the best flavor, or divide clumps in spring. Seedlings vary in taste.
Companion planting
Oregano is a low, sun-loving herb for the edge of vegetable beds, and its flowers are a pollinator magnet.
Good companions
- Tomato A classic kitchen pairing; oregano at the bed edge brings in pollinators.
- Bell pepper Shares the same sun and dry-side watering at the bed edge.
Pests and diseases
Oregano has few problems apart from rot in wet soil.
Pests to watch for
- Aphids Clusters on young shoots.
- Spider mites Fine speckling on leaves in hot, dry weather.
- Leaf miner Pale winding tunnels in leaves.
Diseases to watch for
- Root rot Wilting and dying stems in wet, poorly drained soil.
Common questions
Which oregano is best for cooking?
Greek oregano, Origanum vulgare subsp. hirtum, is the standard culinary oregano. Many other oreganos are mainly ornamental and milder.
When should I harvest oregano?
Pick leaves any time; the flavor is strongest just before the plant flowers, which is the best time to cut stems for drying.
Why is my oregano dying?
Wet, poorly drained soil is the usual cause. Oregano needs sun and sharp drainage and should be watered sparingly.
Does oregano come back every year?
Yes, it is a hardy perennial in most of the US, roughly zones 4 to 8. In hot, wet climates it can be short-lived, so grow it in a pot or raised bed.
Can I grow oregano from seed?
Yes, but seedlings vary in flavor. For the best taste, buy a plant or take cuttings from one with good aroma.
