How Do You Know When To Pick Plums

You know when to pick plums by checking for a deep, uniform color, a slight softness at the stem end, and a sweet fragrance.
 
But knowing exactly when to pick plums isn’t always as straightforward as it seems.
 
Plums can be tricky because they don’t all ripen at the same time, even on the same tree.
 
The key is to understand that plums are climacteric fruits, meaning they continue to ripen after being picked.
 
So you actually have a little flexibility when deciding when to pick plums.
 
You can pick them slightly under-ripe and let them finish on your counter.
 
However, there’s a big difference between plums picked at the right moment and those picked too early.
 
In this post, we’ll explore the telltale signs for when to pick plums, how to test for readiness, and what to do after you’ve made the harvest call.
 
Let’s dig in so you can enjoy the sweetest fruit possible.
 

Key Signs For When To Pick Plums

The most reliable way to know when to pick plums is to rely on your senses rather than just the calendar.
 
Here are the primary signals that your plums are ready or nearly ready for harvest:
 

1. Color Change Is Your First Clue

When to pick plums often starts with watching the skin color closely.
 
Most plum varieties shift from green to their mature color, which could be deep purple, red, yellow, or even blue-black.
 
But don’t just look at the shaded side of the fruit.
 
Check the side facing the sun and the side facing the tree’s interior.
 
When both sides have fully changed color, that’s a strong sign it might be time to pick plums.
 
If there’s still a greenish tint near the stem, give them another few days.
 
That green area often indicates the fruit isn’t fully mature yet.
 

2. The Gentle Squeeze Test

Another classic method for knowing when to pick plums is feeling for a slight give.
 
Plums that are ready will yield just a little when you press gently near the stem end.
 
They should feel like a ripe peach or avocado, soft but not mushy.
 
If the plum is rock hard, it’s not ready to pick from the tree.
 
If it feels like a water balloon, it’s almost overripe and may bruise easily.
 
The ideal moment for when to pick plums is that window between firm and fully soft.
 

3. Trust Your Nose for Aroma

Ripe plums give off a sweet, fruity fragrance that’s hard to miss.
 
When you’re determining when to pick plums, bring your nose close to the fruit.
 
If you can smell that honeyed, floral scent, the plum is likely at peak maturity.
 
Under-ripe plums have almost no detectable aroma.
 
The fragrance develops as sugars increase and acids mellow out.
 

4. The Ease Of Separation Test

A ripe plum should come off the tree with a gentle twist and lift.
 
When to pick plums becomes easier once you understand that ripe fruit releases from the branch cleanly.
 
If you have to tug hard or the stem tears the fruit’s skin, it’s not ready yet.
 
Wait a few days and try again.
 
Also, check for plum fruit that has already fallen to the ground.
 
When you see a few ripe plums dropping naturally, that’s nature’s signal that it’s time to pick plums from the tree.
 

Understanding Plum Ripening After Picking

Now that you have a sense of when to pick plums from the tree, let’s talk about what happens afterward.
 
Plums will continue to ripen after harvest, which is a huge advantage for home growers.
 
This means you don’t have to wait for perfect softness on the branch.
 
By picking plums at the first sign of color change and slight firmness, you can let them finish indoors.
 
That’s great news because it reduces the risk of birds, wasps, and rot taking your crop first.
 

How to Ripen Picked Plums Indoors

If you’ve picked plums a little early, simply place them in a single layer at room temperature.
 
Avoid direct sunlight, as it can cause uneven ripening and shriveling.
 
To speed up the process, put the plums in a paper bag with a ripe banana or apple.
 
The ethylene gas released by those fruits will help your plums soften faster.
 
Check them daily because once plums start ripening, they can turn quickly.
 

When to Pick Plums for Different Uses

Your intended use also changes when to pick plums.
 
For fresh eating, you’ll want fully ripe, soft plums with maximum sweetness.
 
For baking pies or making jam, slightly firmer plums work great because they hold their shape better.
 
For canning or freezing, pick plums at the firmer stage of ripeness.
 
And if you’re planning to make plum wine or a tart sauce, you can even pick them a bit under-ripe for extra acidity.
 
So think about how you’ll use them when deciding exactly when to pick plums.
 

Common Mistakes When Gauging When To Pick Plums

It’s easy to second-guess yourself, but here are common errors to avoid.
 

1. Picking Based Only On Calendar Dates

While each plum variety has a typical harvest window, weather and local conditions shift that timeline.
 
Don’t rely on the calendar alone for when to pick plums.
 
A hot, sunny spring can push ripening weeks earlier.
 
A cool, cloudy spell can delay it just as much.
 

2. Harvesting All Plums at Once

Plums ripen sequentially, meaning not all fruits on a tree are ready on the same day.
 
So when to pick plums is more of a process than a single event.
 
Check your tree every two to three days over a couple of weeks.
 

3. Ignoring the Weather Forecast

If heavy rain or strong winds are coming, it’s better to pick plums slightly early than to lose them.
 
Wet conditions can cause cracking and fungal issues on ripe fruit.
 

So, How Do You Know When To Pick Plums?

You know when to pick plums by combining color, softness, aroma, and ease of separation from the branch.
 
Look for full color change on both sides of the fruit, a gentle yield when pressed, and that unmistakable sweet scent.
 
Then, pick plums with a slight firmness if you plan to ripen them indoors for a few days.
 
And always remember that plums ripen after picking, so err on the side of picking a couple of days early rather than too late.
 
With these tips in your back pocket, you’ll nail the perfect harvest window every single season.
 
Enjoy every juicy bite of your well-timed plum harvest.
