Features & Attributes
English Walnut has dark green foliage throughout the season. The large pinnately compound leaves turn yellow in fall. The flowers are not ornamentally significant. It produces brown nuts in late fall. The fruit can be messy if allowed to drop on the lawn or walkways, and may require occasional clean-up.
This is a deciduous tree with a more or less rounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition. This plant will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting squirrels to your yard. It has no significant negative characteristics.
Aside from its primary use as an edible, English Walnut is sutiable for the following landscape applications;
- Orchard/Edible Landscaping
Planting & Growing
English Walnut will grow to be about 50 feet tall at maturity, with a spread of 50 feet. It has a high canopy with a typical clearance of 6 feet from the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a medium rate, and under ideal conditions can be expected to live to a ripe old age of 120 years or more; think of this as a heritage tree for future generations! This is a self-pollinating variety, so it doesn't require a second plant nearby to set fruit.
This tree is typically grown in a designated area of the yard because of its mature size and spread. It should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This species is not originally from North America.
