Step 3: Planting Potatoes

The quality of seed potatoes is very important, so choose them carefully from the garden store. Do not grow potatoes that you buy from the market, as they are not suitable for cultivation because they are treated with chemicals to prevent germination and diseases.

In addition, the potato seeds that you buy from the garden store are guaranteed to be completely disease-free and of high quality. Sow the potato seeds in deep soil so that the soil is 4 cm deep under the seeds, then bury them again with 3 cm of soil. 

The soil must be wet, but not too wet, because this may spoil the seeds, so the soil must be light and well-drained so as not to retain large amounts of water. Take care of your plants and watch them well. Potatoes do not need much water, they should be watered when the top surface layer is dry

Potatoes need nutrient-rich soil, so fertilize your soil with compost or commercial fertilizer such as superphosphate fertilizer, Bonimil.

The Main Crop

Do not water potato plants between the time of plant death and harvest, to allow the dry period, which is an important period for drying and hardening of the skins, which is a very important point for long storage of potatoes later.
