Fencing, dogs, guns or all three! Or just plant things they don't eat which isn't much.
First find out which type of deer is doing the damage, probably roe or muntjack. This tells you how high your fence and how fine the mesh needs to be. You would need to fence your whole property to the same standard as they will happily come through your neighbours gardens and walk up the road to get to yours.
Deterent sprays are a waste of time and money as you need to keep re-applying all year round.
