How long to stop watering potatoes before harvest?

As a gardening and landscaping expert, I can share with you the best practices for harvesting potatoes. When it comes to stopping watering potatoes before harvest, it is recommended to let the potatoes cure underground for approximately two weeks. This time period allows the skins of the potatoes to toughen up, resulting in a better texture and improved storage capabilities.

During this curing period, the potatoes are still growing and developing. By withholding water, you are essentially signaling to the plant that it is time to start preparing for dormancy. This process helps the potatoes form a protective layer on their skins, making them less susceptible to damage during harvest and storage.

Stopping watering the potatoes around two weeks before harvest also helps the plant redirect its energy towards the maturing tubers rather than focusing on foliage growth. This can result in larger, more robust potatoes.

Personally, I have found that allowing the potatoes to cure underground for this specific duration yields the best results. The skins become thicker and more resilient, making them easier to handle during harvest. Additionally, the potatoes seem to have a better flavor and texture when given this curing period.

During this two-week period, it is important to monitor the soil moisture levels. While you should stop regular watering, you may still need to provide some water if the soil becomes excessively dry. However, it is crucial to avoid overwatering, as this can lead to rot or other issues.

To ensure proper curing, it is recommended to dig up a small portion of the potatoes after the two-week period to check if the skins have sufficiently toughened up. If they appear too tender or easily damaged, you can leave them in the ground for a few more days before harvesting the entire crop.

Stopping watering potatoes approximately two weeks before harvest allows the skins to toughen up and prepares the plants for dormancy. This curing period enhances the texture, flavor, and storage capabilities of the potatoes. Monitoring soil moisture levels during this time is essential to avoid overwatering. Personally, I have found that following these guidelines results in a successful potato harvest with delicious, long-lasting tubers.
