How to Protect Strawberry Berries from Gray Rot Featured

-️Gray rot particularly thrives in humid summers. The spores of this fungus are found in the soil, so the main task is to prevent the berries from coming into contact with the ground. If the fruits are isolated from the soil, the risk of disease will be significantly reduced.



-️A good option is to grow strawberries on black mulch. Also, during fruiting, you can place boards under the flower stalks, tie them to the trellis, carefully tie up the bushes with twine, or set up small supports.



-️For prevention, it's useful to water the soil and the bushes themselves with a solution of "Fitosporin" once a week.



-️After the end of fruiting, treat the plantings with "Bordeaux mixture" (approximately 1 teaspoon per 0.5 liters of water).



-️Another effective remedy is the preparation "Zircon". It strengthens the plant's immunity and helps it resist fungal, bacterial, and even viral diseases.



-️During harvesting, be sure to remove berries affected by gray rot. Place them in a separate container and bury them far from the strawberry bed to a depth of a shovel blade.


Once we buy strawberries, it only takes us a few days to use a quart. To facilitate consumption, we remove the stems, and either:

  • My husband's method: soak them in tapwater acidulated with bottled lemon juice
  • My method: squirt a little bottled lemon juice over them, agitate gently, then rinse with tap water

Then we remove excess water and put them in a storage box with a double layer of paper towel on the bottom.

I find the lemon juice is unnoticeable.

Thanks Cindy. I'll try it. I've always left them in the perforated plastic box they come in, in the fridge but often the ones on the bottom start rotting within about 2 days. Right now our Aldi has a sale; a 1 lb box for $1.29. They look fully ripe with no green or white areas on the berries and have a strong sweet strawberry odor.
