I’ve planted two walnut trees over the years here in our gardens and neither of them have survived. People always tell me ‘but they grow like weeds!’ Yeah right, not for me they don’t. For many years whenever I took a trip down South I would see these beautifully lush trees growing along the banks of the mighty Waikato River. They looked so exotic and I used to try and figure out what species they were. One day the penny dropped and I recognised them as thriving walnut trees. Then I understood why they hadn’t been happy, here, in my garden. Walnuts naturally choose fertile, moist, lime rich locations. I have read that European settlers coming to the eastern parts of the USA would often choose to build their homes near a stand of walnut trees. They understood the best place to plant a garden. All that goodness seems to be absorbed by this stately and medicine rich tree. It has many gifts to share; nutrient dense food, exceptional medicine and the finest timber. Read the full post for all the details.

Traditional and Historical Uses;?North American Indians used the black walnut to treat a number of ailments in both humans and animals. Juice made from green walnut husks was used to clean maggots out of wounds and to rid dogs of intestinal worms (Niethammer, 1974). The White Mountain Apache tribe rubbed their horses and livestock with a concoction of husk juice to protect the animals from parasites (Niethammer,1974). A tonic made from walnut bark was also used to treat aches and pains associated with rheumatism. The European walnut, juglans regia, has very similar active ingredients and been used extensively throughout Asia, Europe and the Middle East. Throughout the centuries European herbalists used the nut, the bark, the roots, and the leaves; as an astringent, a laxative, a purgative to induce vomiting, a styptic to arrest the bleeding of wounds, a vermifuge to expel worms or parasites such as head and body lice, and a hepatic to tone the liver. The walnut served to induce sweating, cure diarrhoea, soothe sore gums and relieve inflamed tonsils. It was highly recommended for all manner of skin diseases; eczema, psoriasis, impetigo, herpetic eruptions, syphilitic chancre, hives, boils, acne, ulcers and sores.

Gardening Applications; The Black walnut produces juglone, a chemical that is poisonous to many plants. Care must be taken when choosing plants that will share any space with the walnut tree. Don’t use fallen leaves, twigs or nuts as raw mulch, instead gather and compost the material to allow the juglone to be broken down over time by composting micro-organisms.
