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 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.

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.

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.

What are the enemy plants of alyssum?

Planting these plants next to alyssum 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 alyssum. Because of these negative effects, we don’t recomment growing the plants below next to your alyssum.
