Can Potatoes Mature in Cody?
Growing degree days measure how much useful warmth typically accumulates during the season. For potatoes, this helps estimate whether local heat accumulation is usually enough for the crop to reach maturity on time.
From the usual planting window, Cody typically provides about 1355 growing degree days for potatoes. With a typical crop target of 1100, that leaves a heat margin of +255. That heat margin usually gives the crop a dependable buffer, so gardeners have some flexibility in planting date and variety choice without pushing the crop close to the edge.

| Checkpoint | Remaining GDD | Heat margin | Fit vs typical target |
|---|---|---|---|
| Apr 15 | 1365 | +265 | Comfortable |
| Jun 1 | 1327 | +227 | Comfortable |
| Jun 15 | 1248 | +148 | Usually fits |

- Norland — often chosen for earliness and good fit in shorter-season gardens
- Dark Red Norland — a familiar early potato with solid short-season appeal
- Kennebec — productive and versatile, but better with a decent amount of runway
- Gold Rush — can do well where the season is supportive and planting is timely
- Russet Burbank — more exposed in short-season areas because it wants a longer finish
| Variety class | Typical days to maturity | Typical GDD need | Local fit |
|---|---|---|---|
| Very early | 70–80 | 900 | Good fit |
| Early | 80–90 | 1000 | Good fit |
| Mid-season | 90–105 | 1100 | Good fit |

How Frost Affects Potatoes in Cody
Cody usually has about 121 frost-free days, with a typical last spring frost around May 27 and a typical first fall frost around September 25.
Potatoes are generally lightly frost tolerant and temperatures below about 28°F ( -2 °C) can slow growth or damage plants.
Potatoes are usually tolerant enough of cool conditions that frost dates act more like planning markers than hard limits. In practice, timing and steady early growth matter more than avoiding every light frost.
The most common setbacks here are practical: planting too late, losing momentum early, or choosing varieties that ask for more season than necessary.
In Cody, potatoes usually have a solid seasonal margin when planted around May 6. The warmest garden spots are usually south-facing walls, sheltered gardens, raised beds, and sunnier urban lots. Cooler spots like low spots, exposed sites, and shadier yards tend to warm up later and usually provide less heat. For potatoes, warmer garden spots usually improve early growth and can make timing a little more forgiving.
