Description
The black walnut is an imposing, fast-growing tree from North America with valuable, dark wood and small, intensely aromatic nuts. Like all walnut relatives, it releases the compound juglone through its roots and leaves, which inhibits sensitive neighbors such as tomato, potato, and apple. Therefore, plant it generously and alone.
Care instructions
Plant the black walnut in a sunny spot with deep, nutrient-rich, moist soil; it grows very large and needs space. Plant in autumn (November, week 44) and keep the root area moist for the first years. Harvest the nuts in October (week 42); the thick, coloring outer shell must be removed with gloves.
