Juglans nigra Black Walnut

Juglans nigra Black Walnut is a stately deciduous tree prized for its productive nut crop and striking architectural form. Growing 15–25 metres tall, this North American native develops a broad, spreading canopy with deeply lobed, aromatic foliage that turns golden-yellow in autumn.

Highly adaptable to Australian conditions, Black Walnut thrives in full sun and well-draining soil. Once established, it's drought-tolerant and requires minimal maintenance. The tree produces abundant crops of nutritious walnuts in their distinctive green husks, ripening through late summer and autumn.

Beyond its culinary value, the rich timber is sought for woodworking, and the tree provides excellent shade and wildlife habitat. Naturally hardy and long-lived, it's an investment piece for properties with space to accommodate its mature size.

Ideal for Australian growers seeking a dual-purpose tree combining productivity, beauty, and longevity.

As recommended by the Swiss Rose Garden Nursery.

  1. Dig a hole 60cm wide and 60cm deep. If the topsoil is usable, separate it from the sand as it can be re-used in the hole. When planting roses in an existing rose bed or where roses have been previously grown during the last 5 years, the soil must be replaced.
  2. Mix together a mixture that contains 2 parts topsoil, 2 parts compost, 1 part manure or buy a Soil Improver, Landscaping or Rose Soil mix from a Landscape supply place. About 100 litres per planting hole is recommended.
  3. A layer of manure can be placed at the bottom of the hole and then the hole filled with the above soil mix.
  4. Place one handful of slow-release fertilizer at 20cm depth from the top where the roots of the newly planted rose will be situated.
  5. Soak the soil thoroughly and lightly compact.
  6. Now plant the rose in this mix with the surface of the plant even with the surface of the prepared area, e.g., the graft union should be about 5 to 10 cm above soil level.
  7. Water every day for the first six months from October onwards, up to 10 litres per day during warm weather is recommended for strong deep root development.
  8. Plant roses 1m to 1.2m apart.

Enjoy the beautiful roses!
