When to pick Italian plums is the question every home orchardist faces as those small, purple fruits begin to swell on the branch.
The best time to pick Italian plums is when they are fully mature but still slightly firm, usually from late August through early September, depending on your specific growing zone.
Picking Italian plums at the right moment ensures you get that perfect balance of sweetness and that classic tart edge these plums are known for.
In this post, we’ll walk you through exactly when to pick Italian plums, how to tell they’re ready, and the best methods for harvesting and ripening them off the tree.
Let’s dig into the sweet details so you never bite into a disappointing, chalky plum again.
When to Pick Italian Plums: The Perfect Harvest Window
When to pick Italian plums really comes down to a combination of calendar dates, visual cues, and a simple touch test that any gardener can master.
Italian plums, also known as Empire plums or prune plums, are a specific variety that ripens differently than the larger, juicier eating plums you find in grocery stores.
Knowing when to pick Italian plums means understanding that these plums are climacteric fruits, so they will continue to ripen after you harvest them.
That said, you still want to pick Italian plums at a point where they’ve accumulated enough sugar and developed their signature deep purple-blue color.
1. Check Your Hardiness Zone and Local Climate
The first clue for when to pick Italian plums comes from your USDA hardiness zone and the specific microclimate of your yard.
Italian plums generally thrive in zones 5 through 9, and the harvest window shifts earlier in warmer southern regions and later in cooler northern areas.
If you live in zone 9, you may be picking Italian plums as early as mid-August, while gardeners in zone 5 often wait until mid-September.
Pay attention to your tree’s bloom time in spring because the fruit typically needs about 120 to 140 days from full bloom to reach harvest readiness.
Mark your calendar when you see those first blossoms, and you’ll have a reliable estimate for when to pick Italian plums in your neck of the woods.
2. Look for the Deep, Uniform Purple Color
Color is your most obvious visual signal for when to pick Italian plums because these fruits have a very distinctive appearance as they mature.
A ripe Italian plum will have a deep, almost navy-purple skin that looks dusty or frosted due to a natural waxy bloom.
If you’re wondering when to pick Italian plums and the fruit still shows any greenish or reddish patches, it’s not ready yet.
The entire plum should be uniformly dark purple, including the area near the stem, which is often the last part to color up.
When that color change happens, you’re getting close to the ideal time to pick Italian plums.
3. Test for the Perfect Firmness and Give
While color tells you a lot, knowing when to pick Italian plums also requires a gentle squeeze to check the fruit’s texture.
Hold the plum in the palm of your hand and press lightly with your thumb, if it feels rock hard, it needs more time on the tree.
If it gives slightly under pressure like a ripe peach but still holds its shape, that’s your prime window for picking Italian plums.
Avoid plums that feel mushy or overly soft on the tree because those have likely passed their peak and may attract pests or rot quickly.
A slight softness at the stem end is a great indicator that the plum is mature enough to pick.
4. Taste a Sample Plum for Sweetness
The most delicious way to determine when to pick Italian plums is to simply taste one that looks mature and feels firm.
Pick a plum from the sunniest side of the tree, wait a few minutes, and bite into it to check the flavor profile.
If the flesh is sweet with a pleasant tang and no astringent bitterness, you’ve found the right time to pick Italian plums.
If it tastes starchy or sour, leave the rest on the tree for another few days and test again.
Remember that Italian plums will get sweeter off the tree, so you can pick them slightly earlier if you plan to ripen them indoors.
Harvesting Your Italian Plums the Right Way
Once you’ve decided it’s time to pick Italian plums, you need to use proper harvesting techniques to avoid bruising and damage.
Italian plums have tender skin, and any bruise you create during picking will turn into a soft, brown spot that ruins the fruit quickly.
1. Pick in the Morning and Avoid Wet Fruit
The best time to pick Italian plums during the day is in the early morning when the fruit is cool and firm from the night air.
Cooler fruit is less prone to bruising, and the tree’s sap pressure is lower, which makes the plums separate more cleanly from the stem.
Avoid harvesting right after rain or when the plums are covered in morning dew because wet fruit invites fungal growth in storage.
If you can, wait a few hours after any rain to let the surface dry before you pick Italian plums.
2. Gently Twist and Lift, Never Pull
To know when to pick Italian plums and how to do it, you should use a gentle twisting motion rather than yanking the fruit.
Cradle the plum in one hand and lift it upward while giving it a slight twist, it should come off the spur easily if it’s ready.
If it resists your twist, it’s not mature enough, so just leave it and try again in a couple of days.
Always keep the small stem attached if possible because plums with stems last longer in storage.
3. Use a Ladder or Picker for Higher Branches
You won’t always be able to reach the highest fruit, so plan ahead when it’s time to pick Italian plums from tall trees.
Use a sturdy orchard ladder and a harvest pouch or a soft basket that hangs from your shoulder so you keep both hands free.
For the very top branches, a fruit picker pole with a basket and padded fingers works wonders for gently catching each plum.
Drop the plums into a shallow container lined with a soft towel to minimize the impact and prevent bruising.
How to Ripen Italian Plums After Picking
Even when you pick Italian plums at the peak of color, they may still need a few days on your counter to reach perfect eating texture and sweetness.
Italian plums ripen nicely off the tree, so you don’t have to worry if you picked them just a touch early.
1. Let Them Sit at Room Temperature
Simply placing your picked plums in a single layer on the counter at room temperature will encourage them to soften and sweeten.
This works best in a spot that’s around 65 to 72 degrees Fahrenheit, away from direct sunlight and drafts.
Check them daily because they can go from firm to overripe quickly once they start releasing ethylene gas.
2. Speed Up Ripening with a Paper Bag
If you need those plums ready for a recipe sooner, place them in a brown paper bag with a ripe banana or apple for a day or two.
The extra ethylene gas produced by the banana will accelerate the ripening of your plums significantly.
Keep the bag loosely closed but not sealed tight, as you still want some airflow to prevent moisture buildup and mold.
So, When Should You Pick Italian Plums?
When to pick Italian plums is ultimately about balancing that deep purple color, slight softness, and a taste test that says they’re ready.
You should pick Italian plums in late summer to early fall, typically from mid-August to mid-September, once they are fully colored and show a gentle give.
The key is to pick Italian plums while they’re still firm enough to handle but mature enough that they will ripen beautifully on your counter.
Hope this guide helps you nail that perfect harvest window and enjoy the sweetest, most flavorful Italian plums right from your own tree.
Happy picking, and may your plum harvest be abundant and delicious.
