What to plant this week in Cheyenne, WY
Cheyenne gardeners are entering the critical late-season crunch where the ground is cooling rapidly but specific cold-hardy crops like garlic and daikon radish still need to be in the soil. With average last frost day May 1 behind us, focus shifts entirely on harvesting these final treasures before the first freeze arrives mid-October. The semi-arid climate means you must prioritize moisture retention for any remaining root development.
The next 7 days
Cheyenne, WYGrowing in Cheyenne right now
- Soil temperatures are dropping quickly; ensure garlic cloves are planted deep enough (2 inches) to survive potential sub-zero dips toward -15°F without rotting.
- Loofah and Roselle vines need immediate final harvest as the first frost on October 15 will ruin fiber quality and leaf texture instantly.
- Apply a thick layer of straw or dried alfalfa mulch around transplanted garlic now to insulate against Cheyenne's notorious wind chill and rapid soil freeze.
- Monitor irrigation closely; while winter rains are unlikely, occasional late-season moisture events can cause rot in wet soils if drainage isn't managed.

Seasonal tips
- Finish sowing cold-hardy greens now to maximize yields before the soil warms up significantly.
- Prepare raised beds by adding compost ahead of time so they are ready for transplanting in June.
- Plan your succession schedule for tomatoes, peppers, and eggplant to ensure a continuous summer harvest.
Pest & disease watch
- Late-season aphid swarms may still attack Roselle leaves before frost kills them off naturally.
- Cutworms often emerge in cool nights to sever young garlic shoots just above the soil line.
- Slugs and snails thrive in damp microclimates near irrigation lines, targeting tender Daikon radish tops.
Watering this week
Water deeply and consistently now that the ground has thawed, aiming for about 1 inch per week to encourage strong root establishment.
Apply a light layer of mulch around transplants once they are in the ground to retain moisture as the soil temperature fluctuates.
Cheyenne gardening questions
3Can I still transplant anything into Cheyenne's ground this week?
No new transplants should be put in; the risk of hardening off before the October 15 frost is too high for most tender crops. Focus your energy on harvesting existing plants like loofah and finishing garlic instead.
How do I prepare my Cheyenne garden bed for winter after harvesting?
Remove all crop debris to reduce overwintering pests, then till in compost if you plan to plant cover crops next spring. Add a heavy layer of organic mulch to protect against the severe temperature swings between daytime warmth and -15°F nights.
When exactly should I harvest my Daikon radishes to avoid freezing damage?
Pull your daikons as soon as they are full-sized, ideally within the next two weeks before soil freezes solid. Leaving them in too long can cause internal cracking from temperature fluctuations or root rot in wet spots.
