Are your strawberries getting grey mould even though you fertilise and water them?
The reason for such "behavior" of the culture should be sought in inappropriate neighbors. The culprit is the neighborhood with raspberries.
Its roots secrete substances that suppress the immunity of berries.

If the beds are closer than 2 meters, the fungus attacks in the first wet week.
Immediately transplant the strawberries to the place where onions or garlic grew - their phytoncides will disinfect the soil. Add a handful of sand to the holes: it will remove excess moisture.
If replanting is not possible, mulch the soil with pine needles - the resin will slow the spread of rot.
And never plant strawberries after nightshades: tomatoes and potatoes leave behind bacteria that are deadly to berries.
In just a month, healthy bushes will produce tendrils, and next season you will forget about mold.
If raspberries are already growing nearby, dig a 30 cm deep groove between the beds and fill it with lime - this will stop the aggressive roots.
For emergency help, spray the strawberries with an iodine solution (10 drops per bucket of water) - iodine will kill the fungal spores.
And to restore the soil, sow mustard: its roots will cleanse the soil of toxins.
Never plant strawberries in a low area - cold air accumulates there, which increases rotting. And if raspberries bloomed last year, wait two seasons before making a new bed.
