When to Pick Avocado From Tree
Avocados are versatile, nutrient-packed fruits that are a great way to add flavor and nutrients to your diet. For avocado enthusiasts, knowing when to harvest your home-grown avocados is a critical step to ensure they are at the peak of their flavor and potential.
How They Grow: Maturity of Avocado Fruit
Avocados are fruits on a striking evergreen tree with lobed leaves and white or pale yellow flowers. A tree can begin to bear fruit as early as three years of age and can produce hundreds of fruits in one season; however, the peak season for avocados is between late spring and early summer. As an avocado matures on the tree, it stores energy from the sun, making it sweeter and more flavorful. Therefore, understanding the season and monitoring the maturity of the fruit is essential to successfully harvesting avocados.
Signs of Ripe Avocado Fruit
When determining if an avocado is ripe, there are several signs that indicate it is ready for harvesting. One indication of ripeness is to inspect the color of the skin. The color and texture of the skin changes as an avocado ripens; expect a firm, shiny and vibrant color that is harder to remove from the tree when ripe. A slight give when gently pressed is another indication of ripeness. People may also examine the shape and size of the avocado to help determine ripeness, as larger avocados are typically softer and more ripe. If a stem is attached, it should also be easy to remove from the fruit.
Harvesting
Harvesting an avocado is best done by hand. Once ripe, use one hand to hold the stem, if it is still attached, and the other to gently twist the avocado, loosening it and gently pull the fruit away from the stem. If the stem is not attached, locate the stem scar, which is the circular, protruding scar where the stem used to be, and gently pull the fruit away from the tree. After harvesting the fruit, it will further mature and ripen at room temperature. Avocados can be stored in the refrigerator for up to two weeks.
Additional Ripeness Tips
It can be difficult to determine if an avocado is ripe and ready to harvest. If an avocado does not delineate the signs above, a simple test can be conducted. Cut an avocado in half and, if it is ripe, a working knife should move through the flesh easily. A knife that is stuck indicates that the avocado is not ripe. Additionally, you can jiggle the avocado and observe its motion; ripe avocados should move freely, and unripe avocados will lack in motion.
Food Safety
The United States Department of Agriculture recommends that all fruits, vegetables, and other potentially perishable items be consumed within four to five days of being harvested. To ensure food safety, it is important to practice thorough food handling and preparation. Wash avocados before eating and ensure that perishable foods are properly stored, cooked and refrigerated.
Taking Care of the Tree
Regular maintenance and pruning of an avocado tree helps to ensure that it is healthy and continues to produce delicious avocados season after season. A healthy tree should have well-fertilized, deep-rooted branches and healthy twigs with a symmetrical shape. To maintain a healthy tree, ensure that it is watered and weeded on a regular basis. It’s also important to check for pests, such as aphids, mites and scale, and treat them accordingly.
Storing the Produce
When avocados are ripe, it is essential to store the fruit properly to prevent it from spoilage. For best results, store avocados at room temperature away from direct light and wait until the fruit has ripened further before moving it to the refrigerator. Additionally, store the fruit away from other strong-smelling foods, like onions and garlic, to prevent it from absorbing the odors. Once ripe, avocados should be kept in the refrigerator and can last for up to two weeks.
Using Aviation Technology to Assess Avocado Maturity
In recent years, advances in technology have allowed avocado growers to measure the maturity and quality of avocados without having to harvest any fruit. Through the use of unmanned aerial vehicles (UAVs), it is possible to collect data and use imaging technology to analyze the spectral response of the avocado fruit and measure its maturity. This technology allows farmers to assess the maturity of the fruit without having to pick and open individual fruits, thereby saving time and reduce the amount of fruit lost to spoilage.
Using Artificial Intelligence to Assist in Harvesting
In the future, artificial intelligence (AI) could be a tool to help farmers produce better yields by increasing efficiency and accuracy when harvesting. AI could assist with identifying and isolating ripe fruits on the tree and predict when to harvest for optimal quality and taste. Additionally, AI could be used to predict the performance of a tree over time and identify areas of the tree where harvests have become sparse or have decreased.
Extending the Shelf Life of Avocados
After avocados are picked, they start to break down due to the enzymatic processes without proper storage. After an avocado is harvest, the fruit needs to be cooled quickly to maintain its freshness. Modern refrigeration technologies, such as vacuum cooling, are being used to extend the life of avocados by reducing respiration rates and slowing down the ripening process.
Exploring Food-Grade Coatings for Avocados
In recent years, several companies have begun to explore food-grade coatings to further extend the shelf life of avocados. The coatings use certain chemical compounds to reduce the rate of respiration and other enzymatic activities that cause avocados to break down. In addition to helping preserve the fruit’s flavor, these coatings could also extend the life of avocados even further, potentially allowing them to stay fresh for weeks or even months.
Exploring Organic Treatments
Organic avocado treatments are an option for farmers who are reluctant to use chemical-based treatments to preserve the quality of their fruit. Organic treatments may include the use of certain compounds, such as beeswax, that act as a barrier against moisture loss, oxidation and spoilage. Additionally, there are other organic treatments, such as oils and plant-based extracts, that could be used to help preserve the quality of avocados for a longer period of time.
Sustainability of Harvesting Practices
When harvesting avocados, it is important for farmers to consider the long-term sustainability of their harvesting practices. To reduce the amount of waste and spoilage, the harvesting process should be done in a way that minimizes the stress placed on the fruit and the tree. Additionally, farmers should avoid over-harvesting, as this can put stress on the tree and its branches and reduce future yields.
Effective Placement of Bat Houses to Encourage Pollination
In order for avocados to produce fruits, pollen needs to be transferred between flower buds. To ensure that pollination occurs, farmers should consider placing bat houses near avocado trees, as bats are the primary pollinators of avocado trees in many areas. Bat houses should be placed in areas that receive ample sunlight and away from areas with excessive noise, such as busy roads. Additionally, farmers should ensure that the bat houses provide protection from harsh weather, such as strong winds and heavy rains.
Pest Control Strategies for Avocado Trees
Farmers should also be mindful of various pests that can affect the production and quality of avocados. Common avocado pests include aphids, mealybugs, spider mites, and scale insects. To protect the fruits from these pests, farmers should use an Integrated Pest Management (IPM) system that involves mechanical, biological, cultural and chemical controls. Additionally, farmers should use natural repellants and safely discard any diseased or damaged avocado fruits to reduce the spread of pests.
Conclusion
Harvesting avocados is a delicate process that requires careful planning and monitoring. By understanding the season and properly identifying ripe fruit, farmers can ensure that their avocados are harvested at the peak of their flavor and potential. Additionally, farmers should practice sustainable harvesting practices to preserve the health of the tree and ensure long-term yields. Ultimately, with careful harvesting and the use of modern technology and practices, farmers can ensure they get the most out of their avocado tree.
