Can Black Walnut Trees Be Grown from Seed? Can They Be Grown from Nut Meat Like Pecans and Almonds Can Be Grown from Their Shells?
Growing Black Walnut Trees from Seed
Black walnut trees can be grown from seed, but the process is not as straightforward as growing other nut trees like pecans and almonds. Black walnuts have a thick, hard shell that must be cracked open before the nut meat can be planted. The nut meat must also be stratified, which is a process of exposing it to cold temperatures for a period of time to simulate the winter conditions that it would experience in nature. Once the nut meat has been stratified, it can be planted in well-drained soil in a sunny location.
Growing Black Walnut Trees from Nut Meat
Growing black walnut trees from nut meat is not recommended, as the nut meat is often damaged during the cracking process and may not germinate. Additionally, the nut meat of black walnuts contains a compound called juglone, which can be toxic to other plants. If you do decide to try growing a black walnut tree from nut meat, be sure to crack the nut carefully and plant the nut meat in a location where it will not come into contact with other plants.
