To get rid of black spots on peaches, you need to identify the cause first and then treat it both on the tree and after harvest.
Those unsightly dark patches can show up on your beautiful peaches for several reasons, and figuring out exactly what’s going on is the first step to getting rid of black spots on peaches for good.
Whether you’re dealing with fresh peaches in your orchard or peaches you just brought home from the store, the approach is similar.
In this post, we’ll walk through why black spots on peaches appear, how to remove them, and how to prevent them from coming back.
Let’s get into it.
Why Black Spots on Peaches Appear
Black spots on peaches don’t just show up randomly.
They’re almost always a sign of something specific, and knowing what that is will help you get rid of black spots on peaches much more effectively.
1. Fungal Infections Like Brown Rot and Scab
The most common reason you’ll see black spots on peaches is a fungal infection.
Brown rot is a big one, and it starts as small brown spots that darken and spread quickly.
Peach scab is another culprit, creating small dark spots that look like black freckles on the skin.
These fungi thrive in warm, humid conditions, especially when your peaches stay wet for too long.
2. Bacterial Spot Disease
Bacterial spot is another major cause of black spots on peaches.
It shows up as tiny dark lesions on the fruit’s surface, and it can also affect the leaves and twigs of your tree.
Unlike fungal issues, bacterial spot loves wet, rainy weather, and it can spread fast once it takes hold.
3. Insect Damage and Sap Bleeding
Sometimes black spots on peaches come from insects like stink bugs or peach borers feeding on the fruit.
When they puncture the skin, sap bleeds out, and that area can turn black as it dries and oxidizes.
If the spot feels sticky or you notice small holes, insects are likely behind those black spots on your peaches.
4. Bruising and Oxidation After Harvest
Even peaches that were perfectly healthy on the tree can develop black spots after picking.
Bruises from handling or transport damage the fruit’s cells, and exposure to air causes oxidation.
This is why some black spots on peaches only show up a day or two after you bring them home.
How to Get Rid of Black Spots on Peaches
Once you know what’s causing the black spots on peaches, you can take action.
Here’s how to get rid of black spots on peaches whether they’re still growing or sitting on your kitchen counter.
1. Prune and Remove Affected Fruit Immediately
If you spot black spots on peaches still on the tree, remove those fruits right away.
Don’t let them drop to the ground, because the fungus or bacteria can overwinter in the soil and reinfect your tree next season.
Also prune nearby branches to improve airflow, which helps dry the fruit faster and makes black spots on peaches less likely to spread.
2. Apply a Fungicide or Bactericide
For fungal causes of black spots on peaches, a copper-based fungicide works well.
Apply it according to the label, usually starting early in the season before symptoms appear.
For bacterial spot, a copper spray combined with good sanitation can help reduce black spots on peaches over time.
Always follow the instructions carefully to avoid harming your tree or the beneficial insects around it.
3. Clean Your Harvest Thoroughly
For peaches already in your kitchen, washing them can help remove surface black spots on peaches caused by dirt or minor oxidation.
Use a soft brush under cool running water, and gently scrub the affected areas.
If the black spots on peaches are just surface-level, this simple step often does the trick.
4. Cut Away Affected Areas
If black spots on peaches have penetrated deeper into the flesh, cut those parts out with a clean knife.
You want to remove at least half an inch of flesh around the spot to make sure nothing contaminated is left behind.
As long as the rest of the peach looks and smells fine, you can still enjoy it.
5. Discard Heavily Affected Peaches
Sometimes black spots on peaches mean the fruit is too far gone.
If the spots are widespread, mushy, or have a foul smell, toss those peaches out.
Eating them could make you sick, and they’ll also release spores that speed up spoilage in your other fruit.
Preventing Black Spots on Peaches in the Future
Getting rid of black spots on peaches is one thing, but keeping them from coming back is even better.
A little prevention goes a long way.
1. Keep the Tree Canopy Open
Proper pruning keeps your peach tree’s canopy open and airy.
Good airflow helps fruit dry quickly after rain, which reduces the conditions that cause black spots on peaches.
2. Water at the Base, Not the Leaves
Watering your tree at the base keeps the foliage and fruit dry.
Wet leaves and fruit create the perfect environment for the fungi and bacteria that lead to black spots on peaches.
3. Sanitize Your Tools and Harvest Baskets
Clean your pruning shears and harvest baskets regularly.
Fungal spores and bacteria can hitch a ride on dirty tools and infect your peaches, causing black spots on peaches you might otherwise have avoided.
4. Choose Resistant Peach Varieties
When planting new peach trees, look for varieties that are resistant to brown rot, scab, and bacterial spot.
This simple choice can dramatically reduce how often you’ll see black spots on peaches in your orchard.
So, How Do You Get Rid of Black Spots on Peaches?
You get rid of black spots on peaches by identifying the cause first, then treating the problem with pruning, fungicides, washing, or cutting away the affected areas.
Black spots on peaches won’t ruin your harvest if you act quickly and take steps to prevent them from returning.
With a little attention and consistency, you can enjoy clean, healthy peaches season after season.
