Propagating Butternut (Juglans cinerea) from Seed: Ontario Extension Guide

Growing Butternut Trees from Fresh Nuts

Butternut (white walnut) seeds require stratification. The Ontario Ministry of Natural Resources provides an excellent PDF:

Key steps: collect ripe nuts, remove husks, stratify 90–120 days in moist peat in fridge, sow 1–2 inches deep in spring. Protect from squirrels.

Butternut is endangered by canker disease; planting seedlings aids conservation.
