The fungus that causes Botrytis Botrytis Botrytis blight, or gray mold —Botrytis and Botryotinia spp. Gray mold is named for the brown, gray, or tan fungal spores that develop on infected tissue when conditions are humid or moist. The tiny, stalked spore-forming structures give rotted tissues a fuzzy appearance when viewed with the naked eye.

Managing Pests in Gardens: Diseases: Botrytis Blight—UC IPM
fruit rot, also known as gray mold, is widespread in the environment. It can infect strawberry flowers when spores landing on them and are exposed to free water during cool weather. Infections can either cause flowers to rot or Botrytis can become dormant in floral tissues.
CORVALLIS, Ore. – Although it’s common to find strawberries in the garden that have turned brown, soft or fuzzy with gray mold, proper watering and yearly renovation can help stem the problem. Strawberries can suffer from a disease called gray mold, also known as Botrytis fruit rot.
- The berries start showing symptoms when they flower.
- The petals and flowering stems turn brown and the entire blossom may die.
- On the strawberry fruit, symptoms may occur on any portion and frequently develop at the stem.
- The tissue turns light to medium brown.
- Lesions in younger, green or white fruit develop slowly.
The fruit may be misshapen as it enlarges. Fruit rot expands rapidly near harvest time, when the berries are turning red. In advanced stages, the fungus produces a gray mold over the fruit surface. Sometimes, rot may not develop until after the fruit is picked.
- To keep gray mold in check or at least prevent it from getting worse, Oregon State University Extension plant pathologist Jay Pscheidt and berry specialist Bernadine Strik offer several strategies.
- Space plants so they dry rapidly after rain and irrigation.
- Don’t water from above.
- Drip irrigation is best.
During the growing season, strawberry plants need about one inch of water a week. On sites with sandy soils or during very hot weather, plants may need more water. Wet the soil to a depth of six to eight inches with each irrigation. Avoid applying so much water that the soil remains saturated for long periods.
Standing water is harmful, even for a day or two. Pick your berries every few days, especially during wet and warmer periods. Refrigerate ripe berries as soon as possible after harvest while removing and composting diseased ones. Fertilize established strawberries in late summer to keep them vigorous and best able to withstand disease and to promote fall growth.
Spring fertilization results in excessive leaf growth and runner formation and doesn’t promote more or larger berries. After harvest season, apply two to three pounds of 10-10-10 (or equivalent well-balanced fertilizer) per 100 square feet of row. Foliage should be dry when you apply the fertilizer.
- You can maintain June-bearing strawberry plants for several fruiting seasons if you manage and renovate them after harvest.
- In Oregon, to avoid spreading gray mold to next year’s June-bearing strawberries, renovate a June-bearing strawberry patch two to four weeks after the last harvest.
- Ever-bearing plants don’t need to be renovated.
To renovate and stimulate next year’s growth in June-bearers, remove the old leaves with a hedge clipper or mower after fruiting, being careful not to damage the crown. Do not remove old leaves on day-neutrals or ever bearers. At the end of the season, remove all plantings that are no longer productive or lack vigor. Want to learn more about this topic?

Why are my strawberries turning mushy on the vine?
Why do strawberries get mushy? – The fruit become soft when it loses water. Once a strawberry is plucked from its stem, it continues to slowly emit volatile compounds and moisture, but it can no longer replace them through its stem. Then, as moisture and nutrient levels continue to decrease, cell walls soften and may even collapse.
If a strawberry has mold or is dark and concave, it’s past saving. Instead of having loose or squishy cell walls, the cells have started to totally break down and the strawberry may be starting to ferment. Not good! But when strawberries just look under the weather, getting water back into them will plump up the fruit again.
You’ll have a fresh snack packed with healthy benefits for later. (You can use overripe or mushy strawberries in baking projects like this ).
What makes strawberries rot faster?
6 Tips for Keeping Berries Fresh Who doesn’t love fresh berries? Except when those berries start growing fuzz within 24 hours of bringing them home. Why do berries go bad so fast? It comes down to moisture and mold. Berries tend to be quite porous, water-rich and delicately skinned, meaning they soak up excess moisture in their environment very easily.
Will strawberry continue to ripen after picking?
Strawberries – Strawberries don’t ripen once they’re picked, so if they don’t look ripe, they never will be. How can you tell which strawberries are the freshest? Look for a bright red colour, a natural shine, and fresh-looking green tops. Avoid berries with white tops or tips.
- Eep berries refrigerated, although they will taste sweeter if you let them come to room temperature before eating.
- Select strawberries that are rich and uniformly red.
- Avoid mushy berries that exhibit signs of mould.
- You can find fresh strawberries in the grocery store any time of the year, but they’re best during spring and summer, fresh off the farm.
Check your local farmers market or find locations to pick your own berries for the sweetest and ripest fruit. If possible, choose organic strawberries to avoid pesticides commonly used in conventional growing. You can also purchase frozen organic strawberries for extra sweetness and a boost of nutrition at any time of the year.
How do you fix soggy strawberries?
We’ve all been there: You dig into a perfectly bright container of strawberries, only to pick off the top layer of perfect berries and see.wrinkly and spotty little fiends that don’t exactly look appetizing. Thankfully, one Facebook user has shared a hack for making those little strawberries look as good as new.
Facebook user Brittany King shared this hack (though she noted we should actually be praising her friend Lilly!) that only involves a bucket of ice water. You’re probably pretty familiar with this trick that can revive things like wilted greens, but it turns out it works with wilted strawberries too.
All you have to do is pop these “sad” strawberries into a bucket of ice water for 20 minutes and boom! They’re back to being bright red and perfectly juicy again. As Totallythebomb.com noted, this isn’t going to work with strawberries that have actually gone bad (please don’t pop moldy strawberries into an ice bath and eat them!!!) but if they have a few imperfections, this should do the trick.

Why does my fruit rot so quickly?
Problem: Rubbery Celery – Solution: Wrap in aluminum foil and store in the fridge. Celery is one of those veggies that can quickly go from crisp and crunchy to rubbery and tasteless, but you can lengthen its life by taking a few extra minutes to store it properly. After separating, washing, and drying the stalks, wrap them in aluminum foil with a small opening. Solution: Line the bottom of your refrigerator’s crisper drawer with a towel. We all grab big heads of leafy lettuce with the intention of serving up light, healthy salads, but a few days go by and suddenly those crisp leaves become limp and soggy. To lengthen the shelf life of leafy greens as well as other produce in your fridge, line the crisper drawer with paper towels.
Another, more environmentally friendly option, Nasar adds, is using washable terry-cloth towels. Moisture in the fridge is what causes most fruit and veggies to lose their crisp texture and start to soften and go bad. By lining your fridge’s veggie drawer, you’ll absorb excess moisture and keep fresh produce crunchy for an extended period of time.
Same goes for those plastic tubs that greens are often sold in: Line those with a paper towel, too. No matter what you’re using, Nasar suggests swapping your towel option weekly, as it will start to get damp over time and that becomes a mold risk if left in the drawer for too long.
How do you slow down fruit rotting?
04 /9 Storage – Storing fruits and vegetables in the right manner has a significant impact on their shelf life. Refrigerating is the best way for slowing down respiration but do not store them inside airtight containers or store wet. As lack of respiration will speed decay.
- Onions, garlic and potatoes are best stored in a cool, dry and dark place.
- Some vegetables should be stored together like apples and apricots with spinach or other leafy greens as they emit ethylene gas, which speeds up ripening.
- Except for herbs and lettuce, you can store all other fruits and vegetables on sheet trays in the freezer for a few days.

Why are my strawberries suddenly dying?
Key Takeaways : –
Dying Strawberry plants is usually because of under watering. If the soil is not consistently moist whilst the strawberry plant’s roots are establishing the leaves lose too much moisture, which causes wilting and brown leaves resulting in a dying strawberry plant. Strawberry leaves turn yellow as a result of root rot and nutrient deficiencies in the soil. Frost damage in the spring can turn foliage brown or black and cause the strawberry plant to die back. Strawberry plants only live for 6 years and can die back due to the fugal disease grey mold and powdery mildew.
How long does it take for strawberries to ripen on the vine?
When to pick strawberries – The best time to pick strawberries can depend on when to plant strawberries and what variety you have. ‘Strawberries only have a relatively small season for harvesting, usually over three or four weeks,’ says Drew Swainston, a former professional gardener and content editor for Homes & Gardens.
‘The exact time for picking strawberries in a home garden will depend on several factors, including the weather, sun exposure, watering regime, and the amount of fertilizer given to strawberries plants, It can be a waiting game for the right moment to pick the fruits and get them at the point they have their best flavor.’ ‘Strawberries will ripen from early summer into fall, depending on the types of strawberry plants that you have,’ continues Drew.
‘It normally takes 4-6 weeks from the first blooms showing on the plants to the first berries being ready for harvest. In milder climates, that can mean the first flowers in April and the first strawberries ready in May. Drew is a former professional gardener who has grown edibles for the last 10 years. He has specialized as a kitchen gardener, growing a wide range of vegetables in productive walled gardens specifically for chefs. He has grown many varieties of potatoes over the years.
Lucy Chamberlain, fruit and vegetable expert for Homes & Gardens, describes the summer strawberry cycle as: ‘In May you eagerly devour the first ripening fruits, during June the yield crescendos deliciously, and by the end of the month fruit quality begins to taper off.’ The best method for knowing when to pick strawberries is to keep a regular eye on them.
‘Strawberry plants produce their fruit in cycles and not all the berries on the plant will ripen at the same time,’ explains Drew. ‘The same plant can have multiple fruits at different stages of ripening. By checking plants regularly, such as every few days, you can then get each berry when it is fully ripe and at its best.’ If you want to eat your strawberries that day, try to pick them at the warmest part of the day as this is when they are their most juicy.

Will unripe strawberries ripen?
Strawberries – Strawberries don’t ripen once they’re picked, so if they don’t look ripe, they never will be. How can you tell which strawberries are the freshest? Look for a bright red color, a natural shine and fresh-looking green tops. Avoid berries with white tops or tips.
At what point do strawberries go bad?
Signs of Rot in Strawberries – Look for these signs to see if your strawberries have gone bad.
- Mold – older strawberries may develop white, dark brown, or black mold. The mold may be furry or look wet. It can be on the red part of the berry or the leaves.
- Soft Spots – rotten strawberries may have mushy spots. The mushy spots may be a slightly darker red or brown.
- Discolored Leave s – if the leaves at the top of the strawberry are turning yellow, are crinkly and brown, or have mold on them, they may be too old to eat. Yellowing or browning leaves are a sign the strawberries are past their prime.
- Smell – if the strawberries have a strong smell that’s acrid or ammonia-like, they are past their prime and shouldn’t be eaten. They won’t taste good and they may make you sick.
Why do my strawberries look bad?
The most common cause of nubby fruits is Tarnished Plant Bug feeding. However, frost injury, boron deficiency, poor pollination, and phyllody also cause deformed berries. Nubbiness caused by tarnished plant bugs almost always occurs at the distal end of the berry.
