Meadow mushrooms?


Question: meadow mushrooms?


a couple of years ago I had a ptao roll laid out in my garden. In these days, after the melting of the snow (fallen in great abundance in my city and remained for at least 30 consecutive days on the lawn) I found the mantle with large light patches of grass that seems as if it were dried up; Is it possible that it is consequent to the cold or could some fungus have proliferated? I thank you right now if you want to give me some advice.

Answer: meadow mushrooms?


Dear Daniel,
the varieties of grass that are used for lawns are generally well resistant to cold and heat; it happens however, especially during exceptionally cold winters such as that of 2011-2012, that the small plants that make up the lawn are exposed to excessively rigid temperatures; in this case these perennials are able to survive only by entering a period of vegetative rest, losing most of the chlorophyll contained in the thin leaves. Therefore, turf spots could be due to the unfavorable climate, and should disappear as soon as the warm weather arrives, or when the plants come out of the vegetative rest, producing new leaves.
Not having images of your lawn available, it is not possible to exclude the presence of various types of fungi; only that the spots caused by fungi in the turf have a very precise shape and color, which make it quite easy to make a diagnosis, to be able to then the most appropriate treatments.
On the gardening forum there are several photos of these fungal diseases, kindly entered by a user, very experienced with regard to lawns, I suggest you take a look, so that you can also intervene on your lawn, if necessary.

As for fungal diseases that can spread in winter, favored by the presence of snow or frost, I remind you of the so-called pink rot, a fungus that develops slowly in winter, producing small roundish blotches, made up of a sort of pink or white cotton; with the arrival of heat, the plants that make up the turf, hit by pink rot, dry up, and the area where the fungus was present remains bare; meanwhile the mushrooms will have settled in another area of ​​the lawn.
Another type of winter-like rot is the gray snow rot; both questions fungi tend to stop their development during the warm and dry months, but their spores will remain in the felt of your lawn, ready to develop when humidity and cold arrive.
So, if your lawn has been hit very severely, you can eradicate the fungus using appropriate fungicides, but if the fungi have caused only small spots, you can simply air the lawn, removing all the felt (which also lurks inside) the spores of the ungo), and re-seeding in the areas affected by the disease.
Often this type of rot is favored by autumn fertilizations that are very rich in nitrogen; the best control that can be implemented against their development consists in using, for the autumn fertilizations of the lawn, a fertilizer rich in potassium.
