I am looking for fruit and veggy plants that grow in zone 4 with morning light only?

lettuce, broccoli, cabbage, broccoli raab, radishes, turnips, Most things need at least 6 hours of sunlight. Don't even bother with tomatoes as they don't like growing as far north as you are and if they do not get 8 hours of full sun a day they will not set fruit well and you will be lucky to get 1 tomato per plants.

Do a search for vegetable plants that like morning sun or part sun and you may come up with other possibilities

You might think about container gardening as you can move the big pots around and into sunny places where there may be no soil.

Vegetables need at least 6 hours of sunlight per day. Like the other poster suggested, plant the veggies in large containers and move them around to catch the full day's worth of sun. You can buy platforms on wheels to move the containers. Check with your local gardening center or plant nursery.

As far as I know, fruit trees need sun too. But ask at your local plant nursery or tree nursery.
