When to Plant Beans in Yarmouth: Timing and Maturity Guide

In Yarmouth, beans are usually a strong local fit. Most gardeners have some room to work with this crop rather than feeling close to the edge.

Typical Planting Window

Strong fit in this climate

Use the planting dates below for beans in Yarmouth.

Typical planting window April 28 – May 12

Typical days to maturity 50–65

Gardeners usually sow outdoors around April 28. Most varieties need about 50–65 days to reach maturity.

Beans are usually a strong local fit in Yarmouth. Most gardeners have some room to work with it here rather than feeling pressed against the calendar.

A stronger fit here gives gardeners more control over finish and timing, but it does not remove the value of careful management.

Best local strategy: Use the normal planting window and manage for consistency rather than trying to squeeze extra season.

Can Beans Mature in Yarmouth?

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) 1282
Typical crop GDD target 900
Heat margin +382

From the usual planting window, Yarmouth typically provides about 1282 growing degree days for beans. With a typical crop target of 900, that leaves a heat margin of +382. 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.

GDD Checkpoints for Yarmouth

If planting later than usual, this table shows how much growing degree day heat is still available from each point in the season. It is most useful for judging how much flexibility you still have before the crop starts losing margin.

Checkpoint Remaining GDD Heat margin Fit vs typical target
Apr 15 1282 +382 Comfortable
Jun 1 1251 +351 Comfortable
Jun 15 1174 +274 Comfortable
Jul 1 1033 +133 Usually fits

Best Bean Varieties for Yarmouth

In Yarmouth, most bean varieties are usually realistic choices. Gardeners can often choose across the maturity range without giving up much day-to-day reliability.

Varieties that often fit well here include:

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

Main risk: The usual setback here is giving away seasonal margin through late planting, slow early growth, or slower variety choice than the crop really needs.

How Frost Affects Beans in Yarmouth

Yarmouth usually has about 179 frost-free days, with a typical last spring frost around April 28 and a typical first fall frost around October 24.

Typical last spring frost April 28
Typical first fall frost October 24
Typical frost-free days 179
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.

Problems here usually come from giving up part of the season through late planting, weak early growth, or slower variety choice than the crop really needs.

In Yarmouth, beans already have plenty of seasonal room when planted around May 5. In practical terms, the best spots are usually south-facing walls, sheltered gardens, raised beds, and sunnier urban lots. Cooler spots like low spots, exposed sites, and shadier yards are more likely to stay cooler and be less forgiving. For beans, the main benefit is often faster early growth followed by steadier pod production from warmer soil.
