Understanding Florida Avocado Varieties and Their Maturity

Florida avocados differ significantly from their Hass counterparts grown in California. They’re generally larger, have smoother, greener skin, and a lower oil content. Understanding the specific variety you are growing is the first step in knowing when to harvest.

Recognizing Different Avocado Types

Florida boasts a diverse range of avocado varieties. Some popular ones include:

‘Choquette’: A large, green-skinned avocado with a watery texture.
‘Monroe’: A late-season variety, known for its excellent eating quality and large size.
‘Donnie’: A cold-hardy variety with good flavor.
‘Pollock’: One of the largest avocado varieties, often exceeding several pounds in weight.
‘Simmonds’: An early-season variety known for its mild flavor.

Each variety matures at a different time of year, ranging from late summer to early winter. Being able to identify your specific type will greatly assist you in determining the optimal harvesting window.

Key Indicators of Avocado Maturity

Unlike some fruits that change color significantly when ripe, Florida avocados require a different set of cues to determine maturity. Don’t be fooled by green skin, it doesn’t always mean that they are unripe.

Fruit Size and Shape: Observe the fruit’s overall size and shape. Has it reached the typical size for its variety? Compare it with photos or descriptions specific to your avocado.
Skin Appearance: While the skin color may remain green, look for a subtle change in sheen. Mature avocados often have a slightly duller appearance compared to young, unripe fruits.
Stem Appearance: The stem connecting the avocado to the tree should be slightly dried and easy to snap. This indicates that the fruit is nearing maturity.
Flesh Feel (Pressure Test): Gently press the avocado near the stem end. A slight give indicates maturity, but avoid excessive squeezing, which can bruise the fruit. This method takes practice and experience.
Seed Coat Color: Cut open a test fruit. The seed coat should be turning brown, not white. A brown seed coat is a reliable sign of maturity.
Days From Bloom: Keep track of the flowering period. Each variety has a typical number of days from bloom to maturity. Local agricultural extension offices can provide specific information for your region.

Performing a Dry Matter Test

The most reliable method for determining avocado maturity is a dry matter test. This test measures the percentage of solids in the fruit and is a good indicator of oil content and flavor.

Collect a Sample: Harvest a few avocados that you suspect are mature.
Prepare the Sample: Cut the avocado in half, remove the seed and skin, and take a sample of the flesh.
Weigh the Sample: Accurately weigh the sample using a kitchen scale.
Dry the Sample: Place the sample in a dehydrator or oven on low heat (around 150°F) until completely dry. This may take several hours or even overnight.
Weigh the Dried Sample: Weigh the dried sample again.
Calculate Dry Matter: Divide the weight of the dried sample by the weight of the fresh sample and multiply by 100 to get the dry matter percentage.

The ideal dry matter percentage varies depending on the avocado variety. Generally, a dry matter content between 21% and 25% indicates good maturity for Florida avocados. Contact your local extension office for variety-specific recommendations.

Harvesting Techniques for Florida Avocados

Once you have determined that your avocados are mature, it’s time to harvest them carefully. Proper harvesting techniques prevent damage and extend shelf life.

Choosing the Right Tools

Using the right tools is critical for a successful and damage-free harvest.

Pole Pruner: This tool is essential for reaching avocados high in the tree. Choose a pole pruner with a sharp blade and a sturdy handle. Look for adjustable lengths to accommodate different tree sizes.
Harvesting Bag: A sturdy harvesting bag worn across the body keeps your hands free for picking and prevents bruising.
Gloves: Wear gloves to protect your hands from scratches and potential irritants from the tree.
Ladder: A stable ladder may be necessary for reaching higher branches, especially on mature trees. Ensure it’s placed on level ground and used safely.
Clippers: Handheld clippers can be useful for detaching individual avocados from lower branches.

The Proper Way to Pick Avocados

Handle avocados with care during harvesting to avoid bruising or damaging the fruit.

Cut the Stem: Use the pole pruner or clippers to cut the stem close to the fruit, leaving about 1-2 inches of stem attached. This helps prevent fungal infections.
Lower Gently: Avoid dropping the avocado. Gently lower it into your harvesting bag or hand it to someone on the ground.
Inspect for Damage: As you harvest, inspect each avocado for any signs of bruising, cuts, or insect damage. Set aside any damaged fruit for immediate use.
Avoid Puncturing: Be careful not to puncture the skin with your fingernails or tools. This can create entry points for pathogens and shorten the avocado’s shelf life.

Harvesting from Tall Trees

Harvesting from tall trees requires extra caution and planning.

Use a Ladder Safely: If using a ladder, ensure it is stable and positioned correctly. Have someone spot you to prevent accidents.
Pole Pruner Technique: Use a pole pruner with a long reach to access high branches. Practice your technique to ensure clean cuts and minimize fruit drop.
Consider Hiring Professionals: For very tall trees or extensive orchards, consider hiring professional tree care services. They have the equipment and experience to harvest safely and efficiently.

Post-Harvest Handling and Storage

Proper post-harvest handling significantly affects the shelf life and quality of your avocados.

Cleaning and Sorting

After harvesting, clean the avocados gently to remove any dirt or debris.

Gentle Cleaning: Use a soft cloth or brush to remove dirt and debris. Avoid using harsh chemicals or soaps.
Sorting: Sort the avocados by size and maturity. This will help you manage their ripening process more effectively.
Culling Damaged Fruit: Remove any damaged or bruised avocados. These fruits are more likely to spoil quickly.

Curing and Ripening

Florida avocados, unlike Hass avocados, need to be cured before they are ripe. This process allows them to develop their full flavor and texture.

Curing Process: Store the harvested avocados at room temperature (around 65-75°F) for several days. This allows the fruit to soften and the starches to convert to sugars.
Ripening Stage: Once the avocados have started to soften, you can move them to a cooler location (around 55-60°F) to slow down the ripening process.
Monitoring Ripeness: Check the avocados daily for ripeness. Gently press near the stem end to test for softness.

Proper Storage Techniques

Proper storage extends the shelf life of your harvested avocados.

Room Temperature: Unripe avocados should be stored at room temperature.
Refrigeration: Ripe avocados can be stored in the refrigerator to slow down ripening. Place them in a paper bag or the crisper drawer.
Freezing: Avocado pulp can be frozen for later use. Mash the pulp with lemon juice to prevent browning and store it in an airtight container.

Dealing with Common Post-Harvest Problems

Even with careful handling, some post-harvest problems can occur.

Anthracnose: This fungal disease can cause dark spots on the fruit. Prevent it by ensuring good air circulation and avoiding overhead watering.
Stem-End Rot: This decay starts at the stem end of the avocado. Prevent it by leaving a short stem attached during harvesting.
Bruising: Handle avocados gently to prevent bruising. Bruised areas are more susceptible to spoilage.

Tips for a Successful Avocado Harvest

Regular Pruning: Prune your avocado tree regularly to maintain its size and shape, making harvesting easier.
Pest and Disease Control: Implement a pest and disease management plan to protect your avocados from damage.
Soil Health: Maintain healthy soil with proper fertilization and irrigation to promote fruit production.
Record Keeping: Keep records of your harvesting dates, yields, and any problems encountered. This information will help you improve your harvesting practices over time.
Local Resources: Consult with your local agricultural extension office for specific advice on growing and harvesting avocados in your area. They can provide valuable information on varieties, maturity indices, and pest control.

Conclusion

Harvesting Florida avocados requires a keen understanding of your specific variety, careful observation of maturity indicators, and diligent post-harvest handling. By following the guidelines outlined in this comprehensive guide, you can ensure a bountiful harvest of delicious, high-quality avocados to enjoy. Remember that experience is the best teacher; with each harvest, you’ll develop a better understanding of your trees and refine your harvesting techniques.

When is the best time to harvest Florida avocados?

The harvest time for Florida avocados varies depending on the variety. Generally, most Florida avocados are ready for harvest from June to January. Determining ripeness isn’t about color change, as many varieties remain green even when ripe. Instead, look for slight softening of the fruit on the tree and a change in the stem color to a more yellowish hue.

Another reliable test is to pick a few of the largest avocados and allow them to ripen on your counter for a few days. If they ripen normally without shriveling or becoming rubbery, the tree is likely ready for harvest. Keep in mind that different varieties mature at different times, so observation is key.

How do I know if my Florida avocado is ripe for picking?

Unlike some fruits, Florida avocados don’t dramatically change color when ripe. The skin might become slightly duller, but generally, it remains green. The best way to determine ripeness on the tree is to gently press the avocado. It should yield slightly to pressure, indicating it’s beginning to soften.

The ultimate test is to pick a couple of avocados that appear to be the largest and most mature, and bring them indoors to ripen at room temperature. Check them daily. If they ripen within a week without shriveling, they are ready to harvest.

What tools do I need to harvest Florida avocados?

Harvesting Florida avocados requires a few essential tools to ensure you don’t damage the fruit or the tree. You’ll need a pair of sharp pruning shears or loppers to cut the avocados from the branch. A long pole pruner might be necessary for reaching avocados higher in the tree.

You will also need a sturdy basket or container lined with soft material (like burlap or bubble wrap) to gently collect the harvested avocados. This helps prevent bruising. Gloves are also recommended to protect your hands from any sap or rough skin.

How do I properly pick Florida avocados from the tree?

Use your pruning shears or loppers to cut the avocado from the tree, leaving a short stem (about 1-2 inches) attached to the fruit. This helps prevent the avocado from rotting prematurely. Avoid pulling or twisting the fruit, as this can damage the branch and potentially the avocado itself.

Gently lower the cut avocado into your padded basket or container. If using a pole pruner, ensure the fruit is carefully caught to prevent it from dropping and bruising. Handle each avocado with care throughout the harvesting process.

How should I store Florida avocados after harvesting?

Florida avocados, unlike many other fruits, do not ripen on the tree. After harvesting, store them at room temperature (around 65-75°F) until they are ripe. Avoid refrigerating unripe avocados, as this can inhibit the ripening process and cause them to become hard and rubbery.

To speed up ripening, place avocados in a paper bag with an apple or banana. These fruits release ethylene gas, which promotes ripening. Once ripe, avocados can be stored in the refrigerator for a few days to slow down further ripening. Monitor them closely to prevent them from becoming overripe.

What are common problems encountered during Florida avocado harvesting?

One common problem is determining the precise ripeness of the avocados, as visual cues can be misleading. Premature harvesting leads to fruit that won’t ripen properly, while delayed harvesting can result in fruit dropping from the tree and becoming damaged.

Another challenge is reaching avocados high in the tree without damaging the tree or the fruit. Using proper tools like pole pruners and taking caution when handling the fruit is important to prevent injury to yourself and damage to your tree.

Can I grow Florida avocados from seed?

While you can grow an avocado tree from seed, it’s important to understand that the resulting tree will likely not produce fruit that is identical to the parent avocado. Seed-grown avocado trees often have a long juvenile period, meaning it can take many years (5-10 years or more) before they start bearing fruit.

Additionally, the quality and characteristics of the fruit from a seed-grown tree are unpredictable. For reliable fruit production that is true to type, it’s best to purchase grafted avocado trees from a reputable nursery. Grafting ensures you’re getting a specific variety with known characteristics.
