The source says a small garden can be more productive when kept small and weed-free, with six to eight hours of sunlight per day.
Shelter from wind is important, well-drained soil is a must, and the garden should be close to water.

Next local check For a first garden and small spaces, NDSU lists tomatoes, carrots, radishes, lettuce, beans, bush squash, bush pumpkins, Swiss chard, potatoes, onions, and peas as plants that are easy to grow or do not need lots of space.

It says tomatoes, peppers, cabbage, broccoli, and cauliflower should be started early for later transplanting, and seedlings should be hardened off for at least two weeks before planting outside.

Climate signals

NDSU Extension Pickin' Patch, H1405, was revised October 2021.
The source says a small garden can be more productive when kept small and weed-free, with six to eight hours of sunlight per day.
Shelter from wind is important, well-drained soil is a must, and the garden should be close to water.
For spring soil preparation, the guide says to squeeze a handful of soil; if it falls apart when you open your hand, it is ready to work.
The guide gives the average last frost-free date for most of North Dakota as May 25.

Planning notes

For a first garden and small spaces, NDSU lists tomatoes, carrots, radishes, lettuce, beans, bush squash, bush pumpkins, Swiss chard, potatoes, onions, and peas as plants that are easy to grow or do not need lots of space.
It says tomatoes, peppers, cabbage, broccoli, and cauliflower should be started early for later transplanting, and seedlings should be hardened off for at least two weeks before planting outside.
Vegetables that tolerate a little bit of freezing include broccoli, cabbage, onions, peas, radishes, rutabagas, and spinach.
Vegetables that tolerate very light frosts include beets, carrots, cauliflower, lettuce, potatoes, and Swiss chard.
Tender vegetables that will die from any frost exposure include beans, cucumbers, melons, peppers, pumpkins, squash, and tomatoes; plant these after danger of freezing temperatures has passed.
For space-saving rows, the guide suggests planting radishes or green onions close to peas or beans, then using the open space after the quick crop is picked.
It also says radishes work well when planted with carrots because harvesting radishes leaves carrots spaced for growth.
For succession planting, it suggests planting a little spinach, then planting another short row when the first row is nearly ready to eat.
The guide says carrot or beet rows can be only 2 to 3 inches apart because wide rows waste space.
For containers, the guide says a 6-inch pot is OK for green onions, radishes, and herbs; a 5-gallon container is needed for tomatoes or peppers; and a 3-gallon container can work for a few climbing green bean plants.
For watering, the guide says the garden needs about 1 inch of moisture per week and morning watering reduces disease risk because foliage does not remain wet overnight.
Harvest cues include green beans when beans start to show in the pod, beets when roots are more than 1 inch, carrots when thumb-sized, lettuce in the morning, snap peas when pods are well-formed, spinach before the main rib gets tough, radishes at about 1 inch, summer squash around 8 inches long, and tomatoes when ripe.
Use these priority catalog links as crop-level examples for the NDSU small-space and frost-tolerance groups, not as cultivar recommendations.
