Cascade English Walnut Tree

English Walnuts (Juglans regia) grow to 50-60 feet tall and 50-70 feet wide at maturity. Grafted trees begin bearing in two to three years. The nuts fall free of their husks when mature. English walnuts grow best in Zones 6-9. Plant in deep, well-drained, permeable soil (at least five to six feet) with pH between 6-7. After planting in winter/spring and watering initially, use rainfall as a guide to keep the soil moist. Young small trees need four to 12 gallons of water per day; larger trees require approximately 20 to 40 gallons per day.
