Kansas Expected Planting Calendar Vegetable Garden

A K-State Research and Extension guide for Kansas planting windows, crop temperatures, frost resistance, spacing, and harvest timing.

Climate signals

• K-State Research and Extension's Vegetable Garden Planting Guide says all planting windows are approximate.
• The guide says Kansas planting windows may need to be adjusted earlier or later depending on the weather each season, varieties chosen, preferred harvest quality, and location in Kansas.
• The average expected planting calendar separates the primary expected planting window for most of Kansas from the marginal possible planting window depending on conditions.
• For indoor seed starting, K-State says to allow 4-8 weeks indoors before transplanting outside.

Planning notes

• Use crop-specific table rows for timing and risk: beans are seeded, need 50-60 days to first harvest, germinate best at 70-85F, and are Tender.
• Beets are seeded, need 50-65 days to first harvest, germinate best at 50-60F, and are Half-Hardy.
• Broccoli is a transplant crop, needs 60-80 days to first harvest after transplant timing, and is Hardy.
• Cucumbers can be seed or transplant crops, need 45-65 days to first harvest, germinate best at 75-85F, and are Very Tender.
• Sweet corn is seeded, needs 68-90 days to first harvest, germinates best at 70-80F, and is Tender.
• Tomatoes are transplant crops, need 52-120 days to first harvest after transplant timing, germinate best at 75-85F indoors, and are Tender.
• Watermelon can be seed or transplant crop, needs 65-90 days to first harvest, germinates best at 80-90F, and is Very Tender.
