Thorny Three-Leaf Orange Plants With Fuzzy Yellow Fruits

Q: I have a bunch of thorny three-leaf orange plants with lots of fuzzy yellow fruit on my property. Are they worth anything? What’s the best way of getting rid of them?

A: I have heard of farmers planting trifoliate orange seeds along a fence row to grow an impenetrably thorny green fence. I suppose the fruit might be edible to some creature but I can’t imagine which animals could stand the sour taste. If you don’t want a green fence and you’re tired of snagging your jacket on thorns, the usual technique for killing nuisance shrubs is to cut them at ground level and immediately spray the stump with triclopyr (Brush Killer) herbicide.
