Growing pecan

nut

Pollination

Needs a 'type I' and a 'type II' variety so pollen shed and female receptivity overlap.

Growing it

Zones 6-9. Needs a long, hot summer to fill the nuts and a lot of room - 40 ft between trees. Northern (fast-filling) types for cooler areas.

Will you get enough chill?

Pecan needs roughly 300–1000 hours between 32 and 45 °F over winter to break dormancy evenly. Check your area with the chill hours calculator. Low-chill breeding has pushed many varieties well below the figure here, so read the plant tag.

Chill and pollination are given at the fruit-type level; specific cultivars can differ. Values are typical ranges for home-garden planning.
