I planted Cherry tomatoes in my garden and the plant grew perfectly. However, I live in a deer infested state and all my cherry tomatoes have been eaten by deer for the past two years. This year I am hoping to actually get to taste my tomatoes. I also already tried putting a short of miniature fence around the plant but the deer stuck its head through my fence and ate my tomatoes.
Deer take serious fencing.
So, fence seriously, further from the plants, and use deer netting which they cannot stick their heads through (they can fit their entire bodies through spaces you'd not think they could, and they can jump more than 6 feet.)
Otherwise, expect another year of growing plants to feed deer with.
This solution may or may not be available to you but works very well. If you can, get yourself a dog. I would suggjest you get yourself a dog which is very trainable and is... well... rather loud. Personally, I like the idea of a hound. From what I understand it is rather easy to train a hound to chase off dear and other wildlife and their natural propensity is to have more bark than bite but since bark is all you need a hound is ideal for warding off wildlife. I have never done it myself but I know a few people who have and apparently the results are excellent. I have even heard storys of hounds being able to ward off larger wildlife like bears and mountain lions (I live in Montana) so there's that.
This maybe isn't the best solution and certainly not fool proof, but could be effective when combined with another option, such as the fencing. I've heard of numerous products and tricks to repel deer from desirable plants. I'll list a few cheap, readily available options here.
Human hair - It's been said that the scent of human hair can be enough to repel deer just by association with humans. Try using the hair from your hairbrush or combs and spread it around the base of your plants. A little gross, but my mother uses this trick on her hosta plants.
Irish Spring Soap - Another option of something cheap that deer are repelled by. Grab a pack of Irish Spring bar soap and either cut it into pieces to scatter around your plants or use a knife to scrape off smaller pieces to make more use of the bar. This is another trick my mother uses and this one lasts a fairly good amount of time. The soap doesn't dissolve too rapidly and shouldn't bother your plants too much.
Cayenne Pepper or garlic - Haven't tried this one but more supposedly repellent smells for deer. The main drawback to this one is that you need to reapply often, as rain will quickly wash this away.
Commercial Products - There are numerous spray products that are available that are designed to repel deer. This Washington post article breaks down a lot of different options and products.
In summary, you may need to adjust your fencing and look to a few of these repellent options to effectively protect your garden from pesky deer.
