Why does companion planting work?

Companion planting works due to several interconnected factors:

  1. 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.

  2. 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.

  3. 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.

  4. Competition Reduction: Companion planting can help reduce competition for resources such as water, sunlight, and nutrients by utilizing plants with complementary growth patterns and root structures. This allows for more efficient resource utilization and healthier plant growth.

  5. 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.

  6. Maximizing Space: Companion planting allows gardeners to make the most of limited space by intercropping plants with different growth habits and maturity rates. 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.

Kale provides invaluable benefits to neighboring plants by enriching the soil with nutrients, suppressing weeds, and attracting beneficial insects like ladybugs and lacewings.

Turnip

Turnips, known for their nutritious roots and garden resilience, grow in loamy soil with a pH range between 6.0 and 7.5. Full sunlight and consistent moisture nurture their robust foliage and prolific root development. Turnips provide invaluable benefits to neighboring plants by improving soil structure, suppressing weed growth, and enriching the soil with nutrients.

Onion

Onions thrive in various soil conditions. Flourishing in well-drained, fertile soil—preferably loamy or sandy—with a pH range between 6.0 and 7.0. Partial sunlight and consistent moisture nurture their hearty foliage and bulb formation. Onions provide invaluable benefits to neighboring plants by deterring pests with their strong aroma and improving soil structure with their fibrous roots.

Potato

Potatoes grows in loose soil with a pH range between 5.0 and 7.0. Full sunlight and consistent moisture nurture their lush foliage and tuber development. Potatoes provide invaluable benefits to neighboring plants by improving soil structure, suppressing weed growth, and adding nutrients to the soil when left to decompose.

What should you not plant next to cabbage?

Planting these plants next to cabbage has a huge negative effect on the development of your plant. Growing enemy plants can appeal detrimental insects, change the taste of the grown plant and even consuming all of the nutrients and water from your cabbage. Because of these negative effects, we don’t recomment growing the plants below next to your cabbage.

Pole Bean

Pole beans flourish in well-drained, nutrient-rich soil with a pH range between 6.0 and 7.5. Full sunlight and adequate support nurture their vigorous growth and prolific fruiting. Pole beans provide invaluable benefits to neighboring plants by fixing nitrogen in the soil, enhancing soil fertility, and promoting overall garden health.

Pumpkin

Pumpkins, known for their gourd-like fruits and garden splendor, grow in various soil conditions. Flourishing in well-drained, nutrient-rich soil with a pH range between 6.0 and 7.5. Full sunlight and ample space nurture their sprawling vines and prolific fruiting. Pumpkins provide invaluable benefits to neighboring plants by shading the soil, conserving moisture, and suppressing weed growth with their dense foliage.
