Potato starts, also known as seed potatoes or seed pieces, are small pieces of whole potatoes that contain at least one "eye" or growth point. When selecting and preparing potato starts, it’s important to follow certain guidelines to ensure optimal growth and yield.

Choosing Potato Starts

When choosing potato starts, consider the following:

  1. Quality of the Seed Potatoes: Purchase certified disease-free seed potatoes from a reputable supplier. This ensures that you are starting with healthy, disease-free planting material.

  2. Size of the Seed Potatoes: Select seed potatoes that are roughly 1 ½ – 2 inches in diameter. Larger seed potatoes can be cut into smaller pieces to maximize planting and yield.

Preparing Potato Starts

After selecting the right seed potatoes, follow these steps to prepare them for planting:

  1. Chitting the Potatoes: To promote faster and more uniform sprouting, place the seed potatoes in a cool, well-lit area for a few weeks before planting. This process, known as chitting, encourages the development of sturdy sprouts.

  2. Cutting the Seed Potatoes: If using larger seed potatoes, it’s recommended to cut them into smaller pieces, ensuring that each piece contains at least one or two eyes. This allows for better utilization of the seed potatoes and increases the number of plants.

  3. Healing Cuts: After cutting the seed potatoes, allow them to dry and "heal" for a day or two. This helps to prevent rot and promotes callusing, which reduces the risk of fungal or bacterial infections.

Determining The Ideal Planting Time

Timing is crucial when planting potatoes to ensure that they have optimal growing conditions and produce a healthy crop. The ideal planting time for potatoes is largely dependent on the climate and the frost-free date in your region. Here’s how to determine the ideal planting time for potatoes:
