Some private security firms (think of the companies who supplement the secret service) recommend trifoliate orange grown into a hedge. It grows well in Hawaii. The dense shrub has sharp, two-inch thorns that make it impossible to cross over, or through the hedge. Once established the dense hedge is capable of stopping a sedan moving moderately fast. It is the true definition of a "living fence".

Although the fruit of trifoliate orange is barely edible, it accepts grafts from other citrus species readily making the living fence functional in many ways.

Cultivation

The cultivar "Flying Dragon" is dwarfed in size and has highly twisted, contorted stems. It makes an excellent barrier hedge due to its density and strong curved thorns. Such a hedge had been grown for over 50 years at Oklahoma State University in Stillwater, and is highly student-proof.[6] The plant is also highly deer resistant.[7]

I am looking at planting a living fence to border my property as opposed to chain link or wood fence. I feel having privacy should be a natural boundary within the land. I have looked at Naupaka plus other local plants and succulents. I know types of bamboo either clumps or spreads, but I can dig a 3 ft trench so it doesn't. I am leaving all my Ohias alone of course, I have only 2 small trees to move for a drive pad, that's it. Any suggestions on landscaping shrubs or trees for a living fence? Does anyone have a living fence?

Try salak palm. They grow together to make a border that no one wants to cross. It is like a porcupine fence if grow the plants a few feet apart. It also has fruit that taste a little like pineapples.

It is the most pig resistant plant I have grown... when you grow a border of them.

Be prepared to deal with the spines!
