You need to take the choice of the planting site seriously. It should be sunny and fairly dry.
If you plant root crops in damp places where water stagnates, the fruits will rot.
As for fertilizers, preference should be given to humus, which can be mixed with compost and peat.
Ash should be added to the hole when planting.
The latter remedy will not only saturate the soil with the necessary elements for normal potato growth, but will also protect against some pests.
It is better to use less inorganic fertilizers.
Also, do not forget about watering. On hot days, the procedure should be done in the morning or evening.
Another important procedure is hilling.
This procedure should be carried out once or twice, when the bushes are already quite tall. This will improve the air supply to the roots of the potatoes, which will help the plants to put down new roots and increase fruiting.
