Harvesting Italian plums involves recognizing key signs of ripeness and employing a gentle, effective picking technique to ensure optimal flavor and prevent bruising. The best method is a careful pull and twist motion, which allows you to gather fruit at its peak without damage.
When Are Italian Plums Ready for Harvest?
Timing is crucial for harvesting Italian plums, as picking them at the right moment ensures maximum sweetness and juiciness. Unlike some fruits that continue to ripen significantly after picking, plums develop most of their flavor and sugar while still on the tree.
Signs of Ripeness:
- Color: Italian plums (often referred to as 'prune plums') typically turn a deep purple, almost black, when ripe. Their skin may develop a whitish, powdery bloom (called "blush" or "bloom"), which is a natural protective coating and a sign of freshness.
- Texture: Gently press the plum with your thumb. A ripe Italian plum will have a slight give when pressed, indicating its flesh has softened. Avoid plums that are rock hard or mushy.
- Ease of Detachment: Ripe plums will easily fall off their branches when twisted. This is a prime indicator that they are ready to be picked. If you have to tug hard, the plum likely needs more time to mature.
- Taste Test: If in doubt, pick one or two plums that exhibit the above characteristics and taste them. They should be sweet and juicy, possibly with a slight tartness near the skin or pit.
Harvesting Season: Italian plums typically ripen in late summer, often from late August through September, depending on your climate and specific variety.
The Best Way to Pick Italian Plums: The Pull and Twist Method
To prevent damage and ensure the best quality fruit, the pull and twist method is highly recommended for harvesting Italian plums. This technique minimizes the risk of plums falling and bruising, which can lead to spoilage.
Step-by-Step Harvesting:
- Inspect the Plum: Before picking, visually inspect the plum for ideal color and check its firmness with a gentle squeeze.
- Grasp Gently: Hold the plum firmly but gently in your hand, near where the stem attaches to the branch.
- Pull and Twist: With a slight upward or outward pull, simultaneously twist the plum. If it's ripe, the stem should separate easily from the branch.
- Avoid Ripping: Do not rip the plum straight off the branch, as this can damage the fruit's skin or the tree's spurs, impacting future harvests.
- Place Carefully: Once detached, gently place the plum into your harvesting container. Avoid dropping them or piling them too high, as they can bruise easily.
Important Considerations:
- Handle with Care: Plums are delicate. Handle them as little as possible and avoid squeezing them tightly.
- Harvesting Tools: For higher branches, a fruit picker with a soft basket can be useful. Ensure the basket has padding to prevent bruising.
- Multiple Passes: You will likely need to make several passes over a few days or weeks to harvest all the plums as they ripen at different rates, even on the same tree.
What to Do After Harvesting
Once harvested, proper handling and storage are key to enjoying your Italian plums.
Post-Harvest Tips:
- Cleaning: Gently wipe plums clean with a soft cloth if needed. Avoid washing them until just before eating or using, as moisture can accelerate spoilage.
- Storage:
- Room Temperature: Ripe plums can be kept at room temperature for a day or two if you plan to use them immediately.
- Refrigeration: For longer storage, place unwashed plums in a single layer in a shallow container or a perforated plastic bag in the refrigerator's crisper drawer. They can last for up to a week.
- Preservation: Italian plums are excellent for drying (to make prunes), canning, freezing, or making jams and jellies.
- Bruised Plums: Immediately use any bruised plums for cooking or processing, as they will spoil faster.
