Hi.
Thank you for visiting Agri Step.
Finally, I harvested potatoes in this time.
Spring planted potatoes are basically harvested until rainy season.
Otherwise, they will get something disease.
Harvest Potatoes
I didn’t use any machinery so I pulled out the potatoes gently and picked potatoes which were left in the land.
If you use shovel, you should be careful. Otherwise, you damage it.
I think I did well.

Although I’m glad to grow good looks potatoes, I learned how difficult it grew as farmer.
I don’t need to care about the looks of them because I will eat but the farmers have to produce to market so “the looks” is really important especially Japan.
My potatoes got 5 types of disease in this season so I will introduce them next.
