Dear Growers,

As harvest winds down, it’s time to focus on the essential postharvest tasks that will set the foundation for next season’s success. At West Coast Nut, we understand the unique challenges California tree nut growers face, and we want to ensure you’re prepared to maximize your orchard’s potential. Here are the top postharvest actions every grower should prioritize for a healthy and productive season ahead.

1. Soil Health Management

Postharvest is the perfect time to test your soil and address any nutrient deficiencies. Applying compost, soil amendments or fertilizers based on these results will ensure your trees have the nutrition they need going into the next season. Additionally, consider planting cover crops to improve soil quality and suppress weed growth.

2. Irrigation System Maintenance

Winterizing your irrigation system is a must to avoid costly damage and ensure peak performance when you need it most. Flush out drip lines, inspect for leaks and check pump efficiency. Cleaning filtration systems now will also reduce maintenance headaches next year.

3. Orchard Sanitation

Removing mummy nuts from trees and the orchard floor is critical to reduce overwintering pests like navel orangeworm (NOW). Good orchard sanitation after harvest is one of the most effective pest management strategies, helping you avoid heavier infestations in the coming season.

4. Pruning and Tree Health

Pruning postharvest can improve airflow and light penetration, which supports tree health and future yield. Focus on removing dead or diseased wood to reduce the risk of fungal infections. Pruning encourages new growth and helps the trees thrive for the next season.

5. Pest and Disease Monitoring

Even after harvest, pest pressure remains. Be vigilant in monitoring for pests such as NOW and implement integrated pest management practices. Tackling pests now will reduce the population going into the next growing season and help you stay ahead.

6. Tree Nutrition Management

Applying postharvest nitrogen is vital to replenishing tree nutrient reserves. This practice supports root health and prepares your trees for a strong bloom in the spring. Proper nutrition now can greatly impact tree vigor and yield next season.

7. Evaluate Orchard Performance

Now is the time to reflect on your orchard’s performance this year. Review yield data, pest pressure and irrigation effectiveness. Use these insights to fine-tune your management practices and develop a strategy for the upcoming season.

At West Coast Nut, we are committed to supporting California’s tree nut growers through every stage of the season. By focusing on these key postharvest tasks, you’ll be well positioned for a successful 2024 growing season. Let’s continue working together to ensure the strength and sustainability of your orchard.

Here’s to a prosperous season ahead!
