Black Walnut Tree
€24.95
Black Walnut (Juglans nigra) is a hardy, long-lived deciduous nut tree, offered here as a young, well-rooted sapling— supplied bare-root from November to March and as a potted tree the rest of the year. Grown from seed, each tree is genetically unique in vigour and form, eventually reaching a substantial 20 to 30 m with a broad canopy and handsome pinnate foliage. After roughly 10 to 15 years, mature trees begin bearing round, green-husked nuts with rich, strongly flavoured kernels, prized in baking, breads, pestos and savoury dishes. Its roots release juglone, a compound that can inhibit some nearby plants, so give it plenty of space and pair it with tolerant species. A long-term investment for large Irish gardens, orchards and agroforestry plantings.

Growing Instructions
Plant in full sun in deep, fertile, well-drained soil enriched with organic matter, allowing generous space for its eventual size and spreading roots. Water well in the early years; established trees are fairly drought-tolerant. Site thoughtfully, as its roots release juglone, which some nearby plants dislike, though many woodland and meadow species tolerate it well. Prune only to remove dead or damaged wood in winter. Nuts ripen in thick green husks in late autumn, usually beginning after 10 to 15 years.
