Irish potatoes require a cool climate with plenty of rain and temperatures ranging from 10 to 23 degrees Celsius. As a result, make sure to plant them in an area that meets these conditions.

Before you plant your Irish potato, you must clear the field of all bush and tree trunks. After that, the land must be tilled and deeply plowed. To loosen the soil and eradicate weeds, dig it again two weeks before the rains start. Manure or compost should also be used to supplement soil nutrients.

Make farm beds that are 2 to 3 inches high to provide the potato plant ample room to grow because it is a root crop that will burrow deep into the soil.

Plant the tubers in raised farm beds that are 30cm high and 80 to 100cm apart. The farm beds can later be raised even higher.

Step 6 – Regular Watering

Water your potatoes regularly after planting. When potatoes first begin to grow, they require moist, enriched soil. Water on top of the fertilizer to aid in its incorporation into the soil.

Step 7 – Fertilizer and Mulching

When the potato’s stem is about 4 inches (10 cm) tall, apply 1 cup (128 g) of fertilizer to the area. It is best to continue the application of the same fertilizer used previously during the land preparation stage. Pour about 1 cup (128 g) of fertilizer for every 30 feet (9.1 m) of row.

Weed control aids in the reduction of competition for moisture, nutrients, and light. As a result, weed when the crop is around 10 cm high and again when it is 20-25 cm high. Weeding early is preferable to avoid plant interaction and the spread of diseases such as the potato virus.

  1. thanks alot. when we make the ridges, do we plant the seeds on top of the ridge or in the depression between?
    what if I don’t make the ridges and just plant the way we plant maize?

    Mutyogoma Joseph

    1. It is preferable you plant on top of the ridges, also you can plant on bare ground.

      Why ridges is good is largely because of two reasons.

      Firstly to bring about more space and prepare the soil for the tubers to grow well and grow bigger.

      Also, for easy harvest during harvest period.
