  4. Fertilizing: Apply a balanced fertilizer, particularly during the growing season.

Growing Onions:

  1. Select Onion Varieties: Choose onion varieties suitable for your climate and soil.

  3. Watering: Onions prefer consistent moisture but can tolerate drier conditions.
  4. Fertilizing: Apply a balanced fertilizer, paying attention to the nitrogen content for bulb development.

While you can plant lemon trees, guava trees, and onions in proximity in your garden, it’s important to ensure that each plant receives the care and conditions it needs. Avoid planting them in the exact same hole or combining their root systems. Additionally, consider the potential size of the mature lemon and guava trees, as they may need adequate spacing for optimal growth.

Always consult local gardening resources or experts for advice tailored to your specific location and conditions. Mixing plants with compatible needs typically leads to more successful and harmonious growth in the garden.
