Benefits of Planting Together

Planting onions and lemongrass together can be beneficial. Onions are known for their pest-repellent properties, which can help protect lemongrass from pests like aphids. Lemongrass, with its strong citrus scent, can also deter pests and attract beneficial pollinators. The combination of these plants can lead to improved growth and flavor, as well as efficient use of space in a garden bed.

Potential Challenges

Apples require more space and have different nutrient needs, which can lead to competition for resources. Additionally, apples are susceptible to diseases that may not affect onions or lemongrass. To overcome these challenges, consider planting apples at a distance where they won’t overshadow the smaller plants.

Planting Tips & Best Practices

• Timing: Plant onions and lemongrass in early spring, while apple trees are best planted in late winter or early spring.
• Container vs. Garden Bed: Onions and lemongrass can be grown in containers, but apple trees require garden beds due to their size.
• Soil Preparation: Use well-drained, nutrient-rich soil for all plants. Amend soil with compost to improve fertility.
• Companion Plants: Consider adding marigolds or basil, which pair well with onions, lemongrass, and apples.
