Sounds as if you are due for a greenhouse. For your starts. There is deer fencing that comes in a package...plastic webbed fencing very very tall. Hard for deer to see and right there is a deterrent. You could get your starts thriving in 10 to 20 gallon pots (use potting soil....). By then you should be able to construct a deer fence; these fences are not vertical. They are at an angle, low on the outside...higher towards the garden you want to protect. I think, grins. Might be the other way...not sure! This mesh stuff should be 'framed' and made into panels. It is huge stuff for very little money. Deer will not 'break through'...
I would also consider purchasing hay to feed them. Take a few bales out away from your garden and keep deer happy. I would also have a few dogs around. I have Elk and deer and feral pigs and bunny rabbits! And feral cats, raccoons, cougar, fisherWell, ravens...horses...I feed them all for harmony. My plants are in a green housedeer fencing hasn't caught up with a wire fence. Absolutely no problems! The main thingwhat is the low wire fence and you could add panels of deer mesh to protect fromknown about deer jumping fences. You feed those deer they will not care Found info on which direction to come closer. Dogs will cementcreate the deal. Another device would be automatic motion sensored sprinkler/sprayers. Very cheaplow end and the high end. deer fence specs
