This can vary depending upon soil conditions, climate zone and species of bamboo. We sell the Bamboo Shield in 24”, 30”, and 36” depths. A good general guide is that 24” is for cold climates (climate zones 5-6) 30” is for warm climates (climate zones 6-8), and 36” if for hot climates (climates zones 8+). **Q: will this work on bamboo that has already spread?** A: It will prevent future rhizoms from spreading but any viable rhizoms outside barrier may continue to spread. You are better off with barrier, the bamboo will become more resilient in time **Q: My neighbors planted 6 palm trees by the fence. Will this prevent roots from destroying my concrete slab?** A: Hi,I'm from Phoenix originally and the palms I've seen have a small root base and I just did a little research and palm trees don't rhizome out like bamboo. If the palm in question is very near to your slab, I would think the barrier would work well since the palm tree article stated that palm roots are thin and can't push through heavy soils and the shield I used is very thick, like 2 times the thickness of a credit card.Hope this helps,David **Q: Do I need the clamp, or can I just overlap it by a couple feet?** A: We recommend using the Bamboo Shield clamp to secure any joints. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth renting a trench digger *by J***N on July 7, 2026* Very sturdy.
