That’s a good plan. First, think about plants that grow quickly and stay dense, like bamboo or rushes—those can create a thick barrier in a short time. For hiding paths, use a mix of low‑lying ground cover, such as creeping thyme or moss, so the ground looks flat and nobody notices a small gap. If you need to slow someone down, plant a row of tall shrubs or evergreens along the edge, so they have to weave through them, losing speed. Keep the understory thick with low‑bushes like hazel or boxwood; they’re hardy and stay dense, so even a casual walker will feel cramped. And remember to keep a little clear space for yourself—no one likes getting tangled in vines while trimming. Use a good mulch on top, it’ll help the plants stay healthy and keep the soil from getting exposed. That should give you a natural fence that’s both tough and discreet.
