Pecans
How frequently and how much should I irrigate?
The most critical time for newly planted pecan trees and shrubs is the first summer after they are planted. Water thoroughly the upper 6 to 8 inches of soil. Provide a weekly soaking rather than frequent light sprinklings. A mulch of pine needles, pine bark, raked leaves or similar materials will help to keep the soil cool and conserve moisture.
Often a loosening of soil around the plants will be helpful and necessary. Normal watering causes compaction and roots need oxygen to grow. Large plants may require a small levee around them to retain the water long enough to soak in.
