Sun exposure

Morning sun and afternoon shade in the low desert; full sun is suitable in cooler high-desert gardens.

Water

Moderate during active growth. Let the upper soil begin to dry, then water deeply; do not leave the crown waterlogged.

Harvest

How to use it

Use fresh or dried leaves in sauces, marinades, roasted vegetables, and herb blends.

Planting & stewardship

How to help Oregano thrive

1
Begin with a flavorful named culinary selection rather than an ornamental oregano if kitchen use is the goal.
2
Mulch the surrounding soil while keeping organic mulch away from the crown.
3
Cut stems back after flowering or winter dormancy to refresh the patch.
4
Divide an established clump when the center becomes sparse.
