What Should I Not Plant Next to Oregano?
Follow these simple steps to create healthy plant partnerships:
| Plant Type | Description | Reason Why It’s Bad for Oregano |
|---|---|---|
| Mint | Fast-spreading herb via underground runners | Takes over garden space and overwhelms oregano |
| Fennel | Tall herb producing growth-inhibiting chemicals | Releases compounds that stunt oregano’s development |
| Water-loving plants | Need constant moisture and frequent watering | Create soggy conditions causing oregano root rot |
| Raspberries | Berry bushes preferring acidic soil and consistent moisture | Require opposite soil conditions and watering schedules from oregano |
| Potatoes | Root vegetables preferring acidic soil and regular watering | Need acidic soil as oregano thrives in neutral to alkaline soil |
Planting Oregano with Companion Plants Effectively?
Follow these simple steps to create healthy plant partnerships that help oregano and its companions thrive together:
1. Proper Spacing
Allow 8-12 inches between oregano plants for compact herb garden settings.
When using oregano as living mulch around vegetables, space plants 12-18 inches apart to provide adequate coverage without overcrowding.
2. Soil and Watering Requirements
Oregano thrives in lean, well-drained soil with a pH between 6.0 and 8.0.
Avoid rich, heavily amended soils that can reduce the concentration of flavorful oils in the leaves.
Water deeply but infrequently, allowing soil to dry between waterings.
3. Sunlight Needs
Full sun exposure (6-8 hours daily) is essential for oregano’s best growth and oil production.
In extremely hot climates, some afternoon shade can prevent heat stress, but morning sun is crucial for plant health.
4. Strategic Positioning
Place oregano near vegetables where its pest-deterrent properties will be most beneficial.
Use it as border planting around vegetable beds or interplant it among susceptible crops like tomatoes and peppers.
5. Maintenance Considerations
Trim oregano regularly throughout the growing season to prevent it from overwhelming smaller companion plants.
Harvest stems frequently to encourage bushy growth and prevent the plant from going to seed too early.
