I'd like to get some fruit trees going this spring in an area where deer frequently pass through. However, putting up a high deer fence (having never done one before) will take so much time away from other pressing projects that I'm considering alternatives. In your experience, how well do individual cages work as an alternative to deer fencing? How high, and of what diameter, do they need to be? How firmly do they need to be secured to the ground? For those who have constructed deer fences around a garden, what creative ideas do you have for a gate?
