Oregano is a versatile herb that can thrive alongside many plants in an herb or vegetable garden. However, some companions should be avoided to prevent competition or even damage to the oregano. This guide will cover 7 plants that are not ideal to grow with oregano and explain why they don’t make good companions.
Why Companion Planting Matters
Companion planting means putting plants together in a garden in a planned way to get the most growth, fruit, and health from them. The right plant pairs can help each other in many ways, such as keeping pests away, making better use of space, and increasing pollination. But plants that aren’t meant to be together may fight over water, nutrients, or light. Some plants even give off chemicals that stop their neighbors from growing. If you know what not to plant with oregano, you can avoid these problems and make a garden landscape that grows well.
7 Plants to Avoid Growing With Oregano
Here are 7 plants that should be avoided when planted near oregano
1. Mint
Mint has roots that spread out quickly and tend to take over garden space. If mint is planted next to oregano, it may suffocate the oregano as it spreads into the soil. Both plants like it when the soil is moist, but mint is better at competing for nutrients and space. For best results, plant mint in containers away from oregano.
Frequency 1
2. Chives
Chives have shallow roots that compete with oregano for nutrients and water in the top layers of soil. Their oniony bulbs also release a substance that may inhibit the growth of oregano. Separate chives and oregano to prevent this allelopathic effect.
Frequency: 1
3. Dill
Tall-growing dill can block sunlight from reaching oregano, potentially causing leggy growth. Dill also prefers slightly different soil moisture and pH levels than oregano. Keep dill and oregano separate to prevent competition.
Frequency: 1
4. Cabbage
Even though cabbage and oregano can grow well together, be careful not to crowd them. If there are too many cabbage plants around oregano, the lower-growing herb may not get enough light. Leave a lot of space between the oregano and cabbage so that air can flow and light can get in.
Frequency: 1
5. Fennel
Like dill, fennel grows tall and may shade out oregano if planted too closely. Fennel also releases chemicals that inhibit the growth of some plants, so give oregano and fennel separate garden areas.
Frequency: 1
6. Potatoes
Oregano and potatoes need different types of soil. Oregano does best in neutral to slightly alkaline soil, while potatoes do best in more acidic soil. It’s hard to change the pH of soil that is shared, so keep oregano and potatoes away from each other for the best results.
Frequency: 1
7. Onions
Onions and oregano both have shallow root systems and can compete for space and soil nutrients. Onions also prefer consistent moisture, while oregano thrives on the drier side. Separate onions and oregano to prevent them from inhibiting each other.
Frequency: 3
How to Choose the Best Companion Plants
When selecting oregano companion plants, look for those with similar sunlight, soil, and watering needs. Herbs like thyme, sage, and marjoram make excellent partners. Vegetables like tomatoes, peppers, and lettuce also grow well with oregano. Choose companions that mature at different heights to make efficient use of garden space. Plants with pest-repelling properties or the ability to attract pollinators are ideal choices. Just be sure to steer clear of the plants listed above to avoid competition with oregano.
Optimizing Your Garden Layout
Proper planning is key to a successful companion planting strategy. Use the following tips when laying out your garden:
-
Group plants with similar needs together. This makes irrigation and care easier.
-
Separate plants that may compete for nutrients, like onions and oregano.
-
Allow enough space between plants for good air circulation and light exposure.
-
Use taller plants to shade lower-growing companions, but don’t crowd them.
-
Interplant quick-growing varieties with slower-developing plants.
-
Repeat plant groupings in different areas to maximize pest control and pollination benefits.
With smart companion selections and proper garden design, your oregano will thrive alongside its ideal partners. Avoid pairing oregano with mint, chives, dill, cabbage, fennel, potatoes, or onions for the healthiest harvest. Using these simple tips, you can create a flourishing garden that takes advantage of the many benefits of strategic companion planting.
Why does companion planting work?
Companion planting works due to several interconnected factors:
Pest Control: Certain plants emit natural chemicals or scents that repel pests, effectively acting as natural pest deterrents for nearby plants. This reduces the need for chemical pesticides and fosters a more balanced ecosystem.
Attracting Beneficial Insects: Some companion plants attract beneficial insects like ladybugs, hoverflies, and predatory wasps, which feed on common garden pests. This creates a natural form of pest control and helps maintain ecological balance.
Soil Improvement: Different plants have varying root structures and nutrient requirements. Companion planting can enhance soil health by reducing soil erosion, suppressing weeds, and improving nutrient uptake. For example, leguminous plants fix nitrogen in the soil, benefiting neighboring plants that require nitrogen for growth.
Competition Lessening: Planting companions with root structures and growth patterns that complement each other can help lessen competition for resources like water, sunlight, and nutrients. This allows for more efficient resource utilization and healthier plant growth.
Biodiversity and Resilience: Planting diverse species together increases biodiversity in the garden, which can enhance ecosystem resilience. A diverse ecosystem is better equipped to withstand pests, diseases, and environmental stresses compared to monocultures.
To make the most of limited space, gardeners can use companion planting to grow plants with different growth rates and ways of maturing. This maximizes yield per square foot and promotes efficient land use.
Overall, companion planting capitalizes on the natural synergies between plant species, creating a thriving and sustainable garden ecosystem.
