I have a meter high front garden wall and I'd like to grow some plants to create some additional privacy. I'm looking for a plant that will grow about 1.5-2 meter tall, evergreen, non invasive and with a shallow root system that wont damage the foundations of my property - I understand deep root systems can suck out water causing foundations to crack and subside.
Any ideas? I've thought about a hedge but not sure how deep the root system is for a hedge. Plus i'd rather have something with low maintenance.
Look forward to your ideas and suggestions.
