How long can I leave potatoes in the ground?

Answered by John Hunt

After the greenery of potato plants has died back, it is possible to leave the potatoes in the ground for a few days under the right conditions. This can be convenient if you are unable to harvest them immediately. However, it is important to keep in mind that leaving potatoes in the ground for too long can lead to rotting and spoilage.

The first factor to consider is the soil moisture. It is essential that the soil is dry when leaving potatoes in the ground. Excessive moisture can promote the growth of bacteria and fungi, which can cause the potatoes to rot. If the soil is wet or waterlogged, it is best to harvest the potatoes as soon as possible to avoid any potential damage.

Another crucial factor is the temperature. Potatoes are sensitive to freezing temperatures, so it is important to ensure that the temperature remains above freezing if you choose to leave them in the ground. Freezing can cause the potatoes to become soft and mushy, rendering them inedible. If there is a risk of frost or prolonged cold weather, it is advisable to harvest the potatoes before it occurs.

If the soil is dry and the temperature is above freezing, potatoes can generally be left in the ground for a few days without significant issues. However, it is important to monitor the weather forecast and be prepared to harvest them if conditions deteriorate. Additionally, it is essential to dig up the potatoes within a few days to prevent any potential rotting.

When it comes to harvesting, it is advisable to do it as soon as possible after the greenery has died back. This is because the potatoes are no longer receiving nutrients from the plants and are more susceptible to decay. By harvesting them promptly, you can ensure their quality and minimize the risk of spoilage.

While potatoes can be left in the ground for a few days after the greenery has died back, it is best to harvest them as soon as possible. The soil should be dry, and the temperature should remain above freezing to prevent rotting. Monitoring the weather forecast and being prepared to harvest if conditions worsen is important. By taking these precautions, you can enjoy freshly harvested potatoes without the risk of spoilage.
