Germination of Walnuts


Walnut trees can be easily grown from seeds by following a few simple steps.

Collect walnuts after they fall to the ground. Remove the husks and then place the nuts in water. Nuts that float are not viable and can be discarded. Good, viable nuts will sink to the bottom.

Before the walnuts will germinate, the nuts need to be exposed to cold temperatures and moist conditions. The cold-moist requirement can be met by planting the nuts in the ground in fall. Plant walnuts 1 to 2 inches deep.
