Plums are one of those fruits that make summer feel a little sweeter. When the season arrives, farmers’ markets and grocery stores begin filling with colorful varieties ranging from deep purple to red, yellow, and even green.
But when exactly are plums in season?
The answer depends on the variety, climate, and where the fruit is grown. In many parts of the United States, fresh plums are most abundant from late spring through early fall, with the peak season generally occurring during summer.
When Are Plums in Season?
In the United States, plum season commonly begins in late spring and continues through summer into early fall.
The exact timing varies by region and variety. Early-season plums may appear in markets around May or June, while many varieties reach their peak during July and August. Some late-season varieties can remain available into September.
This long harvest window is one reason plums are such a popular backyard fruit.
If you grow your own tree, the harvest date can also vary depending on weather conditions, tree age, and the specific cultivar.
Plum Season by Month
While harvest times aren’t identical everywhere, a general seasonal pattern can help you know what to expect.
May: Early varieties may begin appearing in warmer growing regions.
June: Plum availability starts increasing as more varieties begin to mature.
July: Many plums reach peak availability during midsummer.
August: This is often one of the best months to find a wide selection of fresh plums.
September: Late-season varieties may still be available in some regions.
The exact schedule can shift from year to year, particularly when spring temperatures are unusually warm or cool.
Why Does Plum Season Vary?
Plums don’t all mature at the same time.
There are many different plum varieties, and each has its own harvest window. Some are bred to ripen early in the season, while others mature later.
Climate also makes a major difference.
A plum grown in a warm region may ripen weeks earlier than the same type of fruit grown in a cooler area. Elevation, spring weather, summer temperatures, and local growing conditions can all influence harvest timing.
This is why there isn’t one exact date that applies to every plum tree.
European Plums and Japanese Plums
Two broad groups commonly found in gardens and markets are European plums and Japanese plums.
Japanese-type plums often ripen earlier and are commonly associated with summer harvests. They tend to produce relatively juicy fruit with a wide range of skin colors.
European plums generally ripen later and often have firmer flesh. Some are particularly well suited to drying and cooking.
There are many individual varieties within both groups, so the actual harvest period can vary considerably.
When Are Plums Best at the Grocery Store?
During peak local plum season, you are more likely to find a wider selection of fresh fruit.
When shopping, look for plums that feel heavy for their size and have healthy, unbroken skin.
Depending on the variety and how ripe the fruit is, a plum may be firm or have a slight amount of give.
Avoid fruit with extensive bruising, leaking juice, or visible mold.
If the plums are still firm, you can allow them to ripen at room temperature before eating.
How to Tell When Seasonal Plums Are Ripe
A plum’s color can provide a useful clue, but it isn’t always enough.
Different varieties naturally have different skin colors, so the best way to judge ripeness is to combine several signs.
Gently press the fruit with your fingertips. A ripe plum should have some give without feeling mushy.
You can also smell the fruit. A ripe plum often develops a noticeable sweet, fruity aroma.
Once the fruit reaches the ripeness you prefer, you can eat it immediately or refrigerate it to slow further softening.
When to Harvest Plums From Your Backyard Tree
If you grow a plum tree, harvest timing requires a little observation.
Some plums are best picked when they have reached mature size and color but are still somewhat firm. They can then finish ripening after harvest.
Other varieties can develop better eating quality when allowed to ripen further on the tree.
Instead of relying only on the calendar, check the fruit regularly as the expected harvest period approaches.
Look at its color, firmness, aroma, and how easily it separates from the tree.
What Happens After Plum Season?
Fresh plums become less abundant once the main harvest season ends, but that doesn’t mean you have to stop enjoying them.
One of the best ways to extend the season is to freeze extra fruit while it is plentiful.
Wash and dry the plums, remove the pits, and cut them into halves or slices. Freeze the pieces on a tray before transferring them to freezer-safe bags or containers.
Frozen plums work particularly well in smoothies, baked goods, sauces, and desserts.
You can also preserve plums by drying or using appropriate canning methods.
How to Make the Most of Plum Season
If you have access to plenty of fresh plums during summer, take advantage of the harvest while the fruit is at its best.
Eat some fresh, refrigerate ripe fruit that you aren’t ready to use, and preserve any excess before it becomes overripe.
You can also use seasonal plums in a variety of recipes, including:
- Plum pies
- Fruit crisps
- Smoothies
- Homemade sauces
- Jams and preserves
- Plum cakes
- Fresh fruit salads
- Oatmeal toppings
Buying or harvesting during peak season can also give you access to better flavor and a wider variety of plums.
Why Backyard Gardeners Love Plum Season
For gardeners, plum season is more than simply a time to buy fresh fruit.
A productive plum tree can provide a surprisingly large harvest from a relatively small backyard space. Once the fruit begins changing color and approaching maturity, checking the tree becomes part of the daily gardening routine.
The harvest can also give you an opportunity to experiment with different ways of storing and preserving the fruit.
If you have several plum varieties, their different harvest dates can extend the period when fresh plums are available in your garden.
Final Thoughts
The plum season in the United States generally stretches from late spring through early fall, with many varieties reaching peak availability during the summer months.
July and August are often especially good times to find fresh plums, although the exact timing depends on the variety and growing region.
Whether you’re buying plums at a local market or harvesting them from your backyard tree, pay attention to firmness, aroma, color, and flavor rather than relying on the calendar alone.
And when you have more plums than you can eat fresh, freezing and other preservation methods can help you enjoy the taste of summer long after the main season has ended.
