Also to know is, can you plant tomatoes in summer?
Summer planting may be necessary when an early tomato crop fails, or if you planted early season determinates and their crop has already matured. When choosing the ideal time to plant, remember that tomatoes grow best when daytime temperatures are between 70 and 80 degrees Fahrenheit.
Keeping this in consideration, what can you plant in a garden in June?
In June, plant root vegetables like radishes, carrots, beets, and potatoes, so that their sprouts appear after the last frost (which can happen mid-June in high mountain regions). Hardy plants like peas, scallions, kale, and chard also do well sown straight into the ground.
In U.S. Department of Agriculture plant hardiness zones 8 and 9, start seeds as early as mid-January; in USDA zones 3 or 4, wait to start seeds until mid- to late March and early April. Wait two weeks after the last frost date to plant seeds or set transplants outdoors.
