Planting time

Spring is the basis for growing potatoes. I hate the heat so I plant it from late February to early April and harvest before the end of the rainy season.
It can also be planted in the fall in warmer regions, in this case can be planted from late August to mid September and harvested from late November to December.

Be careful about the disease
  • Potatoes are caused by diseases caused by viruses and bacteria, including “fish scales” disease that causes rough and damaged skin. Take care and precautions when choosing soil and taneimo.
  • Grows in well-drained soils as it is moist and spoils easily.
  • When exposed to light, potatoes turn green and produce the poison solanin. Gather the soil at the base of the warehouse so that the potatoes won’t leak, and pay attention to how to preserve them after harvest (introduced in the second part of the article).

To grow large potatoes, it’s important to be prepared before planting!

Do the land first

To prevent scabies should sprinkle rice bran 2-3 weeks before planting and take good care of. Rice bran can be purchased at home centers, rice shops, supermarkets, … and has the effect of drawing out the deliciousness of potatoes.

“Soil is like a cushion that nourishes potatoes. Soil, rich in nutrients and well-developed by microorganisms, produces large and delicious potatoes.”

Prepare Taneimo

The stalk of the potato develops from the parent line, Taneimo, and the new potato forms at the tip. “Kita Akari” is easy to grow even for a beginner. It is highly productive and resistant to scabies.

What needs to be prepared

Taneimo

plant ash (Somokubai), or potato peeling agent

* Taneimo cannot be eaten or grown indoors, but is not infected with virus, etc., and purchased from a garden store. Choose one that does not rot and darken, has no wrinkles, and has strong buds. To plant in the fall, choose a taneimo that is not too small, weighs 50-60 grams or more so as not to get cold.

For spring planting, cut large taneimo into pieces of 50-60 grams or more. Insert the stove vertically with the “umbilical” part (the trace of the part connected to the mother warehouse) facing downwards so that the number of buds is evenly distributed. For small taneimo, scrape off the belly button and plant it entirely. It looks like the growth potential will increase by making a few scratches. Even in the case of autumn planting, the belly button is removed without cutting and planting the entire plant.

Cut it to appropriate dimensions according to the size of the taneimo.On the leftmost side is a small taneimo with the belly button removed.

Taneimo is very perishable at the end, so add vegetable ash to prevent it. Place the vegetation on the plate, smear the ashes on the cut, then wipe it off with your fingers. If you leave it alone, the water and nutrients will be absorbed by the ash, so be sure to wipe it off properly.

Wipe the residue thoroughly so that the cut leaves a little bit of color.

Finally, we will be planting Taneimo in the field!

What needs to be prepared

Taneimo, cow manure compost, organic compound manure

* For organic mixed fertilizers, we recommend mixed fertilizers for potatoes, which are rich in amino acids, which are delicious ingredients.

“If you want to grow large potatoes, it’s important that you grow taneimo,” says Kato.

Plow for a loose and loose soil. The width of the grill is about 60 to 70 cm. Potatoes like weakly acidic soils (pH 5.0-6.0), so it’s a good idea to pre-measure the pH with a soil acidity meter.
