When to Plant Beans in Cody: Timing and Maturity Guide

Beans are possible in Cody, though this is the kind of crop where planning details matter much more than they do for easier crops.

Typical Planting Window

Borderline in this climate

Use the planting dates below for beans in Cody.

Typical planting window May 27 – June 10
Method Direct sow
Typical days to maturity 50–65

Gardeners usually sow outdoors around May 27. Most varieties need about 50–65 days to reach maturity.

Beans can still succeed in Cody, but the crop usually needs better-than-average planning around timing, variety speed, and site warmth.

Cody usually gets into bean planting season slightly later than many other Wyoming locations. That makes local site warmth more important than it would be where the seasonal margin is wider.

Best local strategy: Treat timing and variety speed as part of the strategy, not as optional refinements.

Can Beans Mature in Cody?

Growing degree days measure how much useful warmth the season provides. For warm-season crops like beans, GDD helps show whether local heat accumulation is usually strong enough for the crop to grow steadily and finish before fall.

Available GDD (base 50) 750
Typical crop GDD target 900
Heat margin -150

From the usual planting window, Cody typically provides about 750 growing degree days for beans. With a typical crop target of 900, that leaves a heat margin of -150. That narrow heat margin means small delays or slower varieties can quickly reduce the odds of timely maturity.

GDD Checkpoints for Cody

When planting later than usual, this table shows how much growing degree day heat is still available from each point in the season. As planting gets pushed back, the remaining heat drops and the crop becomes less likely to mature on time.

Checkpoint Remaining GDD Heat margin Fit vs typical target
Apr 15 750 -150 Usually short
Jun 15 739 -161 Usually short
Jul 1 668 -232 Usually short

Best Bean Varieties for Cody

In Cody, very early and early bean varieties are usually the safest choice because they leave the least room for the season to turn against you. Slower classes are much less forgiving here.

Varieties that often fit well here include:

Variety class Typical days to maturity Typical GDD need Local fit
Very early 45–52 725 Tight
Early 50–55 800 Tight
Mid-season 55–65 900 Poor fit
Late 65–75 1000 Poor fit

Main risk: There is not much margin here, so late planting or longer-season bean varieties can easily carry harvest past frost.

How Frost Affects Beans 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.

Typical last spring frost May 27
Typical first fall frost September 25
Typical frost-free days 121
Minimum safe temperature 32°F / 0 °C

Beans are generally frost-tender and temperatures below about 32°F ( 0 °C) can slow growth or damage plants.

Beans are much more exposed to frost risk, so the frost dates matter as real planting boundaries rather than rough planning markers.

The most common problem is running short on season. Late planting, slower varieties, and cooler exposed sites can turn a possible crop into a disappointing one.

In Cody, the seasonal margin for beans is tighter before the usual fall frost around September 25, so microclimate matters more than it does for easier crops. Local gardens do not all warm and cool at the same pace. For a better local margin, gardeners usually do best in south-facing walls, sheltered gardens, raised beds, and sunnier urban lots. Cooler spots like low spots, exposed sites, and shadier yards often make timing tighter. For beans, the biggest payoff is quicker early growth and a little more time to keep pods coming before fall conditions turn.
