Caring for Potatoes (page 2 of 2)

Deep Watering is Best
Potatoes can take some periods of dry weather. However, if it's been very dry and the tubers are beginning to develop underground, water the plants. If you need to water, be sure you do a thorough job, applying enough to moisten the soil 8- to 10-inches below ground. Deep watering is the only way to go. Research shows that irrigated potatoes obtain 57 percent of their water from the top foot of soil, 24 percent from the second foot of soil and as much as 13 percent from the third foot of soil. Though the potato plant is mostly shallow-rooted, some roots do indeed go deep for water.
