When to Plant Beets in Kansas
Published: April 24, 2026
Kansas gardeners in Zone 6b have a 33-week growing season for beet (March 22 to November 10). Kansas's spring and fall windows both work well for beet — some gardeners plant both successions for a long harvest. This guide gives exact dates for Kansas based on your local frost calendar.
Beet Planting Dates for Kansas
| Start seeds indoors | Year-round |
| Last frost (average) | March 22 |
| Direct sow outdoors | February 22–March 4 |
| Expect first harvest | April 13 – May 3 |
| Fall crop start | September 15–25 |
| Fall harvest | November 4 |
| First fall frost (average) | November 10 |
Dates above assume Zone 6b, the most common zone in Kansas. Gardeners in cooler Wichita (Zone 6b) plant 1–2 weeks later; warmer Kansas City (Zone 6a) can plant 1–2 weeks earlier.
⚠ Direct sow beets 3–4 weeks before last frost. Each beet seed cluster contains 2–3 seeds — thin to 3 inches. Succession plant every 3 weeks.
Growing Beets in Kansas's Climate
Kansas's moderate Zone 6b climate is well-suited to beet with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your beet harvest significantly in Kansas. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common beet pests to watch for in Kansas include Leaf Miner and Flea Beetle. The first line of defense is companion planting: Onion and Garlic planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.

Beet Growing Tips for Kansas Gardeners
- •Soak beet seeds 4 hours before planting to soften the tough seed cluster and improve germination rates.
- •Thin seedlings to 3 inches apart — crowded plants produce tiny woody roots rather than full-sized beets.
- •Kansas's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
- •Use thinnings as baby greens in salads; beet greens are more nutritious than the roots.
Companion Planting for Beets in Kansas
In Kansas's moderate climate, planting beet with Onion and Garlic helps deter pests and improve soil. Avoid planting near Pole Bean and Mustard, which inhibit beet growth through root chemistry or shared pest pressure. See the full beet companion planting guide for the complete list.
