Lovely light green compound leaves add a tropical look to trees that can reach 20 meters at maturity (200 years) so plan accordingly. This specie can adapt to many soil types with a pH range of 5 to 7.5, but the better the soil quality is the better the growth along with nut harvest and quality.

How to germinate Carya illinoinensis seed

Nuts will be stored in moist peat to cold stratify. Starts to germinate in early April. I germinate all my nut species in a resealable baggie and tuck them in a box or bucket in an unheated greenhouse. When the warm weather arrives, its warmer in the greenhouse (duh) so germination is promoted sooner. Longer the growing season in their first year the stronger and hardier seedlings will be able withstand their first winter a whole lot better than its late grown kin.
