I have a deer outside my house and it eats EVERYTHING but one plant: lavender. Apparently it smells weird to them (I love the smell) so they don't want to eat it. You could try deer resistant plants, but the deer who lives with us eats it. So, pretty much every plant deer eat.
Gardeners have several options when attempting to preserve their gardens in areas where hungry deer live and forage for food. Indeed, deer will eat almost anything -- and in your garden, will have their own priority of favourite plants.
Physical barriers include sturdy Fencing: see-through fencing allows you to enjoy the garden while keeping the deer away from the blooms. Electrifying it may help deter animals.
Scent barriers: local nurseries can sell you products you can spray on your garden that will 'minimize' your garden's attractiveness to hungry deer -- but none are guaranteed to keep the hungry animals at bay.
Your final option is to plant botany that the deer won't eat, except in times of near starvation. You can follow the link, below, and discover a strategy that may -- with modification for your locale -- help you minimize deer damage in your garden.
Motion activated sprinklers are available and also quite expensive. Electric fence or just an extra tall fence would work, perhaps at less cost. The cheapest solution is probably predator urine (REALLY!) It is available to repel various pest animals from gardens. It will repel humans as well since it is unbelievably foul smelling. For that reason you would not want to actually apply it to your plants, just on the ground on the perimeter of your planted area. A less stinky and probably more easily acquired solution is fish meal or blood meal, either which may disturb finicky animals. These two products are also organic plant foods, so they would be serving two purposes.
Keep in mind that if the deer are experiencing a severe food shortage due to drought, etc., they will be extremely and desperately hungry and nearly impossible to foil except by very sturdy and very high fencing.
You can;t just stop a deer from coming into your yard. If there is food they will come.
well you could out up a fence or you could get something that thay dont like:D but its mainly up to you of what you want to do.
