Answer: Sadly, the most reliable long term safeguard against deer damage is a tall fence. If you have isolated shrubs or trees to protect, you may be able to fence them individually using a cylinder or square of fencing placed around each one.
Some gardeners report success using the spray on repellents labeled for deer, applied and reapplied per the label instructions and possibly alternating between the different brands to avoid the deer becoming accustomed to any one of them.
Some gardeners have also used Milorganite (treated sewage sludge, slight fertilizer action) sprinkled on the ground around their plants with some success.
In my experience, the various home remedies just are not effective when you have a serious deer browse situation.
