when to plant tomatoes in kansas

The best time to plant tomatoes in Kansas is typically in early to mid-May. By this time, the danger of frost has usually passed, the soil has warmed sufficiently (to at least 50°F), and the air temperatures are more favorable for tomato growth. This timing helps ensure vigorous root development and reduces the risk of frost damage. Starting tomato seeds indoors 6-8 weeks before the last frost date (around early March) is also recommended, with transplanting outdoors after nighttime temperatures stay above 50°F. Planting too early risks frost damage and poor growth, while planting too late may delay fruit production before the heat of summer or fall first frost.
