Tips to Grow Potatoes

These tips will surely help you in growing potatoes easily.

The first thing you need to do is use potatoes with eyes (buds) that protrude from certified (disease-resistant) seedlings.

  • Before two days of planting, cut the large potatoes similar to the size of a golf ball with one or two eyes on each half. This is important because after some time the pieces will form a protected layer which will improve moisture retention and rot resistance.
  • Keep the proper spacing between potatoes. The reason is that potatoes grow 6 to 8 inches in depth and they can spread up to 3 inches underneath in the form of rows. 
  • Each trench should have a seed potato piece placed cut side down and covered with three to four inches of dirt every 12 to 14 inches.
  • After two weeks of planting, you will be able to see sprouts. Then pour some more soil around 3 to 4 inches and make sure to leave a few inches of the plant exposed outside. Repeat this until the trench reaches the ground level.
  • Maintain consistent hydration, particularly after the blossom blooms. 1 to 2 inches of water each week are required for potatoes. Inadequate watering during the early stages of potato development and too much watering after planting might result in deformed potatoes.
