While avocado trees may appear dormant during winter, the winter season is crucial for the accumulation of carbohydrates, or energy , which supports the next growth cycle and fruit crop. Despite the apparent inactivity, both leaves and roots remain functional, and fruit continues to grow, albeit at a slower rate.
Optimizing tree conditions during this period is essential for achieving peak performance in the following spring. To ensure the best outcomes, growers should implement the following cultural practices:
Fertilization
- Review the current fertilizer plan and analyze leaf sample results
- Develop and adjust the upcoming fertilization strategy as necessary
- Apply mulch to conserve soil moisture and provide organic matter
Pruning
- Conduct maintenance pruning in frost-free areas to improve light penetration
- Remove dead wood before the rainy season to prevent disease spread
Irrigation
- Adjust watering schedules to account for lower tree water demand
- Perform irrigation system maintenance to ensure efficiency
- Implement leaching irrigations to prevent salt buildup in the soil
Frost and Rain Protection
- Inspect and service wind machines for frost protection
- Enhance natural air circulation within the orchard
- Assess and improve water drainage to prevent waterlogging
By focusing on these key areas, avocado growers can help their trees weather the winter months and set the stage for a productive spring season.
