Consider a section for the three sisters. Easy, and very low maintenance. Beans add nitrogen to the soil, the broad leaves of the squash act as mulch to keep the weeds down, and the corn gives the beans a place to grow.
The Three Sisters: Corn, Beans, and Squash
Get a scarecrow on Amazon. It is motion activated, attaches to a hose and blasts water when a deer or whatever crosses its path. For me, it works for deer, but animals like groundhogs don’t even flinch. Smaller animals I’ll shoot with a paintball gun.
Good soil is far better than miraclegrow type fertilizer. Cow manure is great, but too much of any fertilizer is a bad thing. My grandmother grew up on a farm in Quebec. The best advice she gave people was to go fishing for bluegill, etc, and drop a couple in each hole you’ll add a plant to, then a few inches of soil (let the plant grow into the nutrients. Catch another bucket full of fish, add water, and let it rot. Add a bit of the water to each plant every three weeks or so. Add some more fish and water to the bucket, rinse and repeat. Absolutely disgusting smell, but you won’t find better fertilizer.
A bit of epsomsalts is also good.

Google companion plant. Here’s a start:
Companion Planting Guide Companion plants are used to help each other by attacking beneficial insects, pollinating, and some smell and or taste so bad they help (a bit) keep grazers away.
Make your own tomato cages. I prefer concrete reinforcement wire and zip ties.
Tomatoes - all things being equal, buy determinant plants. I still plant some indeterminant, but they will outgrow your cages by mid summer, and flop over.
Peppers - I’ve had terrible luck with peppers, but this year in my year.
Get a cat or plant catnip to attract a neighbors cat. I had a big problem with mice and voles when I first started gardening. It wouldn’t have been as much of a problem if they took turns eating one tomato at a time. But what they do is nibble on everything.
Save strawberries for later. Far more time consuming (weeding, etc).
Consider planting raspberry and blackberry plants on the outside of your fence (use the fence as a trellis). In a couple years they create a natural fence - a few animals won’t bother trying to get into the garden once the thorns do their work. Most won’t produce fruit for a couple years, but once they do, you'll have more than enough to freeze.
Get some dripper hoses. Put in your plants, then the dripper hoses, then mulch with newspapers (perfectly safe). Top off with salt marsh hay (straw is loaded with weed seeds). Do this, and you’ll have a fairly low maintenance garden.
The devil is in the details - plan well, and prepare the garden before planting.
And my best advice - plant more than you’ll eat. Feed the grazers- no system is perfect, so you might as well feed the ones that get through.
If you are near Hampden/Somers area, shoot me an PM in a month or so. I start from seed indoors, and usually have a couple dozen extra of most seedlings I will plant. If you buy seedling, stay away from Home Depot, Lowe’s, etc. Find a local garden center that grows their own seedling.
