What is the best way of securing my garden space from trespassers?
The best way and easiest way is to install an IP camera. Installing an IP camera will help you view your garden from any place during any time. If you think this is a great idea then go for hybrid IP with IR. This will give you the best picture quality. This will help you to detect if anyone is coming to your garden without your permission and catch hold of them directly. Just read this.
Fencing is the best way. If you are an ambitious gardener and don’t plan on moving the fencing you could also train espelier trees against it. You could also train your vining plants up it – melons, gourds, squash, and beans would be items that climb well. Fences would deter trespassers, critters, and help maximize garden space they can also be cost effective depending on materials used.
