You can get rid of mummy berry on blueberries by breaking the disease cycle early and staying consistent with cleanup, pruning, and targeted sprays.
Mummy berry is one of the most frustrating fungal diseases for blueberry growers, but it’s totally beatable with the right timing.
If you’ve been battling mummy berry on blueberries and wondering how to get rid of mummy berry for good, this post will walk you through each step.
We’ll look at how mummy berry spreads, how to get rid of mummy berry at each stage, and the long-term habits that keep it from coming back.
Let’s dive in so your blueberry bushes can finally thrive.
How to Get Rid of Mummy Berry on Blueberries
Getting rid of mummy berry on blueberries starts with understanding the fungus behind it.
The disease is caused by *Monilinia vaccinii-corymbosi*, and it survives winter in those hard, shriveled berries you see on the ground or still hanging on the bush.
Those little “mummies” are the source of everything that follows.
When you know how to get rid of mummy berry at each stage, you can stop it before it spreads.
1. Remove and Destroy Mummified Berries
The single most effective way to get rid of mummy berry on blueberries is to remove every mummy you can find.
Pick off mummies hanging on the canes and rake up those that fell to the ground beneath the bushes.
Don’t just toss them in the compost, because that keeps the fungus alive on your property.
Bag them up and throw them in the trash, or burn them if burning is allowed where you live.
Do this in late winter and again right after harvest, and you’ll knock out a huge chunk of next season’s infection.
2. Cultivate the Soil Around Your Bushes
Mummies that survive on the ground send up tiny mushroom-like cups called apothecia in spring.
Those cups release spores that infect new shoots, leaves, and flowers.
To get rid of mummy berry before that happens, lightly till or cultivate the soil under your bushes.
Burying the mummies a couple of inches deep stops them from sending up those spore-bearing cups.
A fresh layer of mulch also helps by covering the ground and blocking spore release.
Just be careful not to dig too deep and damage shallow blueberry roots.
3. Prune for Better Airflow
Mummy berry on blueberries loves dense, damp, crowded canes.
Prune out dead, weak, and crossing branches to open up the center of each bush.
Good airflow lets leaves dry faster, and the fungus needs moisture to thrive.
Pruning also makes it easier to spot mummies and remove infected shoots early.
Do your main pruning in late winter, then do light touch-ups throughout the season as needed.
4. Apply Fungicide at the Right Time
For serious infections, fungicides can help you get rid of mummy berry on blueberries.
The key is timing, because sprays only work during specific windows.
Start spraying when buds begin to break and continue through bloom, following your product’s label.
Look for fungicides labeled for mummy berry, and rotate active ingredients so resistance doesn’t develop.
Never spray during bloom if bees are active, since many fungicides harm pollinators.
Spraying at the wrong time wastes money and won’t get rid of mummy berry at all.
5. Keep the Ground Clean Year-Round
Staying on top of fallen fruit and debris is how you get rid of mummy berry for the long haul.
Check under your bushes after rain and after harvest when mummies drop.
Pick up any shriveled berries you spot, even small ones, since each mummy can start a new cycle.
A clean orchard floor is your best defense against mummy berry coming back.
Pair this with mulch and light cultivation for the best results.
Signs You’re Dealing With Mummy Berry on Blueberries
Before you can get rid of mummy berry on blueberries, you need to confirm it’s actually mummy berry.
The disease shows up in two very different forms, and recognizing both helps you act fast.
1. Shoot Blight in Spring
Early in the season, new shoots and leaves suddenly wilt and turn brown or black.
They look like they’ve been scorched, and they often droop in a shepherd’s crook shape.
This shoot blight stage is when the fungus is actively infecting fresh growth.
Removing these infected shoots early helps you get rid of mummy berry before it spreads to flowers.
2. Hardened Mummies Later in the Season
After bloom, infected berries turn pale, then grayish, and eventually shrivel into hard, stone-like mummies.
These mummies are how the fungus survives winter and restarts the cycle next spring.
If you see them hanging on canes or scattered on the ground, you know mummy berry on blueberries is present.
Removing them is the most important step in getting rid of mummy berry.
3. Salmon-Colored Spores on Mummies
In wet conditions, you might notice a fuzzy, salmon or tan-colored growth on the mummies.
This is the fungus producing spores, and it means the disease is actively spreading.
If you spot this, remove the affected berries immediately and dispose of them far from your bushes.
This is a clear sign you need to step up your mummy berry control efforts.
Preventing Mummy Berry on Blueberries Long-Term
Once you’ve done the work to get rid of mummy berry, prevention keeps it from returning.
Choose resistant blueberry varieties when planting new bushes, since some cultivars handle mummy berry better than others.
Space plants properly so air moves freely, and avoid overhead watering that keeps foliage wet.
Water at the base of the plant in the morning so leaves dry quickly during the day.
Keep a consistent cleanup routine every fall and spring, and mummy berry on blueberries will stay under control.
So, How to Get Rid of Mummy Berry on Blueberries?
You can get rid of mummy berry on blueberries by removing mummies, cultivating the soil, pruning for airflow, and spraying fungicide at the right time.
Mummy berry is a persistent fungus, but it’s no match for consistent, well-timed action.
Clean up every mummy, open up your bushes, and stay ahead of the spring infection window.
With a little patience and a solid routine, your blueberry bushes will reward you with healthy, abundant harvests for years.
