Gardeners know a lot about planting potatoes, but they can accidentally forget the most important thing.
For example, you can stock up on fertilizers, pest and disease control products, water and hill the seedlings on time, but the harvest will be so-so. The point is that you can't forget about the planting dates.
In the old days, people managed without lunar calendars and other smart advice, but they rarely went without a second harvest of bread.
There are many signs for this case.
For example, it is not recommended to plant potatoes before the bird cherry begins to bloom.
Here is another piece of folk advice: wait until the birch leaves grow to the size of a 5-kopeck coin of the State Bank of the USSR.
But as for the potato harvest, here, as they say, there is no accounting for the difference. A guaranteed harvest will only be possible in one case.
First of all, you need to pay attention not to your neighbors, nor to bird cherry flowers or birch leaves, but to the soil temperature.
Experienced gardeners don’t even think about going out into the fields until the soil warms up to an optimal 10-12 degrees Celsius at a depth of 7-10 cm.
It is worth noting that the soil does not heat up as quickly as the air, and you cannot do without a thermometer here.
