How to Earth Up Potatoes: The Ultimate Guide

Potatoes are among the most popular and versatile vegetables grown in gardens around the world. They are easy to grow, store well and can be prepared in a variety of delicious ways. However, to ensure a bountiful harvest, it is important to know how to earth up potatoes properly. In this article, we will guide you through the process step by step.

What is Earthing Up?

Earthing up, also known as hilling, is the process of mounding soil around the stems of growing plants. This technique is commonly used for potatoes but can also be applied to other crops such as sweet potatoes, tomatoes, and cucumbers. Earthing up potatoes not only provides support for the plant's growing stems but also helps to protect developing tubers from sunlight, which can turn them green and make them toxic.

When to Earth Up Potatoes?

The ideal time to start earthing up potatoes is when the shoots have grown to about 20cm tall. This usually occurs about 3-4 weeks after planting. At this stage, the stems are sturdy enough to withstand being covered with soil without breaking. It is important not to wait too long to earth up potatoes, as they can become too tall and difficult to mound without damaging the stem.

How to Earth Up Potatoes?

Step 1: Start by loosening the soil around the base of the potato plants using a garden fork or trowel. Be careful not to damage any of the roots.

Step 2: Use a hoe or shovel to create a mound of soil around the base of the plant, covering the lower third of the stem. Make sure that the soil is loose and not compacted to allow air circulation and prevent the soil from becoming waterlogged.

Step 3: Water the soil thoroughly to help settle it around the plant and promote root growth. If the soil settles too much, add more soil to achieve the desired height of the mound.

Step 4: Repeat the earthing up process every 2-3 weeks until the mound reaches a height of 30-40cm above ground level. This will help to protect the developing tubers from sunlight and ensure a good harvest.

Tips for Earthing Up Potatoes

- Avoid earthing up potatoes during wet weather, as this can lead to the soil becoming compacted and waterlogged.

- Do not cover the top of the potato plant with soil, as this can encourage the development of fungal diseases.

- If you are growing potatoes in containers, use a deep container and gradually add soil as the plant grows.

- When harvesting, gently remove the soil from around the base of the plant to reveal the tubers without damaging them.

Earthing up potatoes is a simple but crucial step in growing a successful crop. By following the steps outlined in this article, you can ensure that your potato plants receive the support and protection they need to produce a bountiful harvest. Happy gardening!
