California is also the largest producer of walnuts in the world. It is estimated that there are over 125,000 acres of walnut trees in the state of California.

Horses are susceptible to laminitis, an inflammation of the foot, from exposure to black walnut wood in bedding.

Juice from the Black Walnut husk and inner bark has a characteristic staining property.

Walnuts and hickories produce a chemical called juglone. Black walnut and butternut trees are a problem for landscape gardeners as sensitive plants will not thrive under the canopy of a walnut tree.

In the Greek language a walnut is known as "karyon" which means head. So named because the walnut shell looks like a skull which protects the brain-like kernel inside it.

Walnut shells are used to make sand paper, glues, plastics and cleaning products.

Mature Walnut Trees are a relatively large tree growing to 20-25 metres, or 80 feet plus high. Squirrels love to nest and breed in walnut trees as the walnut fruit provides a good source of food from mid summer to fall. Walnuts grow from a 3-6 cm or 1.25-2.5 inch range and fall with some force.

Black Walnut Tree Wood

Large black walnut trees produce the most highly valued hardwood in North America. Prized for its beautiful grain, black walnut trees are in high demand but this type of tree is becoming very rare. High demand and reduced availability makes this wood, and furniture made from it, very expensive.

Urban grown walnut trees are of little wood value for fear that these trees may contain nails or metal objects which would damage the large saw blades.

Walnut wood is a popular choice for butcher block counter tops in your kitchen. You can apply a variety of finishes to bring out the grain and protect the wood from water and any harsh chemicals.

Black Walnuts

Black Walnuts husks have a surprising smell. A green walnut with its husk still on, which has recently fallen from the tree or green walnut picked off a small tree, has a sweet citron smell that is quite pleasant.

Black Walnut

Black Walnuts have been used to dye fabrics and wool in the old pioneer days. Black walnuts that fall on driveways, pathways and near door entrances can be a problem. One has to be careful after a rain storm not to track in the black dark brownish walnut dyes which can stain your carpets and hallway runners.

Black Walnut Safety

Black Walnuts can grow to a substantial diameter, 2 to 2.5 inch diameter, possibly as large as 3 inches round. Hidden in long grass they are hard to see and one can easy turn an ankle if you step directly on a fallen walnut.

Walnut wood is a straight grained hardwood that ranges in color from chocolate brown to yellow. A popular choice for intricately carved dining tables, headboards and mantels, but be prepared to pay the price!

Walnut Tree Problems

On a windy day stay away from walking, talking or standing under walnut trees, as dead branches and walnuts can fall at any time.

Walnut crop and size of walnuts varies between years. Some years they will be numberous, others years large 2.5 inches round and other years only a few.

The larger your Walnut Tree the more walnuts to clean up in the Autumm.

Fall walnuts best picked up after a windy storm as the walnuts fall to the ground. If you have a lot of walnuts to pick up, best group them in lots and then use a shovel to pick them up.

Favorite walnut picker up is the spade shovel. using the pointed end initially to load walnuts, once no more walnuts will go on, them use the sides to slip more fallen walnuts on before dumping them in your container.

Walnut Tree squirrels seem to try to get rid of you by cutting off walnuts near where you stand to chase you away.

Removing Autumn Walnuts from your property is a way to reduce the attractiveness of squirrels locating nest(s) in your near buy shed, garage or house. Ridding of squirrels can be a pain and one way to prevent a return is to put chicken wire in the hole(s) they create, as wood does not seem to deter them

A tree which bears fruit that is consumed by humans and some animals is called a fruit tree.
