The key to successful companion planting lies in understanding each plant’s growth requirements, pest control benefits, nutrient needs, and spacing.

Growth Requirements

• Radishes: Fast-growing, cool-season crop; prefers well-drained soil and consistent moisture.
• Sage: Perennial herb; thrives in well-drained soil with moderate watering.
• Lemongrass: Warm-season perennial; requires full sun and moist, rich soil.

Benefits of Planting Together

Planting these three together can offer several benefits. Sage, with its pest-repelling properties, can protect radishes from common insects. Lemongrass can enhance the garden’s aesthetic and attract pollinators, while radishes can make efficient use of space by growing quickly and maturing before sage and lemongrass reach full size.

Potential Challenges

Competition for Resources

Radishes, sage, and lemongrass have different water and nutrient needs, which can lead to competition. Ensuring each plant’s requirements are met is crucial.

Different Watering/Feeding Needs

Radishes need consistent moisture, whereas sage prefers drier conditions. Lemongrass requires more water and nutrients. Use drip irrigation or separate zones to accommodate these differences.

Disease Susceptibility
