How to Propagate Walnuts?
Primary propagation of walnuts can be done by seed sowing and grafting. Key factors include stratification of fresh seeds, well-drained soil, and a temperate climate. Special considerations involve protecting young saplings from pests and diseases. Generally, propagation poses moderate difficulty due to the long germination period and need for stratification. Steps include collecting seeds in autumn, stratifying for 90-120 days at 33-41°F (1-5°C), sowing in fertile, well-drained soil, and grafting for desirable cultivars. Regular watering and protection from wildlife are crucial.
