Before you plant

These conditions determine whether it will thrive.

Cold hardiness

Hardy here

Dormant pecans are only hurt near 0°F or below. Late spring and early fall freezes can damage new shoots, flowers and nuts, and Western's late-maturing nuts can stick in the shuck after an early fall freeze.

Heat tolerance

Takes full sun and heat

NMSU notes Western is less affected by heat and water stress than other pecans. Paint trunks and exposed limbs white to prevent southwest bark injury. It also tends to sprout nuts early in low-desert heat.

Planting & stewardship

How to help Western Schley pecan thrive

1
Choose a rootstock suited to the site’s soil, drainage, salinity, desired size, and pest pressures.
2
Plant bare-root trees while dormant, keeping the graft union above finished grade.
3
Thin developing fruit early enough to improve size and reduce limb breakage.
4
Use dormant and summer pruning intentionally to balance shade, access, vigor, and next year’s fruiting wood.
