Typical Planting Window

Strong fit in this climate

Use the planting dates below for pumpkin in Yarmouth.

Optional indoor start April 7
Typical planting window May 7 – May 17
Method Direct sow or transplant
Typical days to maturity 90–110

Pumpkin can usually be started indoors around April 7 or sown directly during the normal local planting window of May 7 to May 17. Most varieties need about 90–110 days to reach maturity.

Pumpkin usually performs reliably when planted on time in Yarmouth. Gardeners generally have enough room to choose varieties for preference, not just for speed.

The season is usually supportive here, but the more useful question is still what turns a safe crop into a notably better one.

Best local strategy: Plant on time, choose the varieties you actually want, and focus on steady growth after transplanting.

Can Pumpkin Mature in Yarmouth?

Growing degree days measure how much useful warmth typically accumulates during the season. For pumpkin, this helps estimate whether local heat accumulation is usually enough for the crop to reach maturity on time.

Available GDD (base 50) 1553
Typical crop GDD target 1300
Heat margin +253

From the usual planting window, Yarmouth typically provides about 1553 growing degree days for pumpkin. With a typical crop target of 1300, that leaves a heat margin of +253. 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.

When Is It Too Late to Plant?

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 1554 +254 Comfortable
May 15 1553 +253 Comfortable
Jun 1 1511 +211 Comfortable
Jun 15 1433 +133 Usually fits
Jul 1 1270 -30 Usually short

How Different Pumpkin Varieties Affect Results

Most pumpkin varieties can succeed in Yarmouth in a typical year. That gives gardeners room to choose for the kind of harvest they want, not just for minimum maturity speed.

Varieties that often fit well here include:

  • Small Sugar — a classic pie pumpkin that is one of the more realistic choices where the season is not especially long
  • Jack Be Little — a very small ornamental pumpkin that fits better than larger types where gardeners want the safest finish
  • Baby Bear — a small pumpkin with useful short-season practicality when gardeners still want a traditional pumpkin look
  • Winter Luxury — a pie pumpkin valued for eating quality, but still more realistic than large carving pumpkins
  • Howden — a classic jack-o-lantern pumpkin that makes sense when the season has enough room for a more standard finish
  • Cinderella — a specialty pumpkin chosen for shape and appearance, but it needs more season than the quickest pie types

Best Pumpkin Varieties for Yarmouth

Early pumpkin varieties are usually the strongest all-around match in Yarmouth. The season can support pumpkin, but staying near the recommended range leaves more room for ordinary delays, cool stretches, and uneven early growth.

For Yarmouth, start with Baby Bear and Winter Luxury for pumpkin when you want small traditional pumpkins or pie pumpkins with stronger eating quality. Choose Jack Be Little and Small Sugar when you want very small ornamental pumpkins or a practical pie pumpkin for shorter seasons. Look at Atlantic Giant, Big Max, and Cinderella when you specifically want novelty giant pumpkins, large pumpkins, or specialty shape and display pumpkins.

Compare each variety’s heat need and maturity timing against the local frost-free window before choosing what to grow.

Fastest / most cushion

Jack Be Little Very early
1100 GDD needed 1553 available before frost
April 28 October 24
Comfortable fit
Why this fit?

Local season fit: Jack Be Little leaves about 453 GDD cushion against the normal Yarmouth crop heat estimate.

Best for: very small ornamental pumpkins.

A tiny ornamental pumpkin that fits better than larger types where gardeners want the safest finish.

Tradeoff: More about appearance and size than substantial eating use.

Small Sugar Very early
1100 GDD needed 1553 available before frost
April 28 October 24
Comfortable fit
Why this fit?

Local season fit: Small Sugar leaves about 453 GDD cushion against the normal Yarmouth crop heat estimate.

Best for: reliable pie pumpkins.

A classic pie pumpkin that is one of the more realistic choices where the season is not especially long.

Tradeoff: Smaller and less dramatic than classic large carving pumpkins.

Also realistic

Atlantic Giant Late
1450 GDD needed 1553 available before frost
April 28 October 24
Tight fit
Why this fit?

Local season fit: Atlantic Giant leaves about 103 GDD cushion against the normal Yarmouth crop heat estimate.

Best for: novelty giant pumpkins.

A giant pumpkin that is usually better treated as a stretch choice where heat and season length are generous.

Tradeoff: The riskiest option here for season length and finish.

Big Max Late
1450 GDD needed 1553 available before frost
April 28 October 24
Tight fit
Why this fit?

Local season fit: Big Max leaves about 103 GDD cushion against the normal Yarmouth crop heat estimate.

Best for: large pumpkins.

A large pumpkin that is much more exposed in shorter seasons because it needs a long, warm run.

Tradeoff: Spends much more of the season on size rather than safety.

Cinderella Mid-season
1300 GDD needed 1553 available before frost
April 28 October 24
Good fit
Why this fit?

Local season fit: Cinderella leaves about 253 GDD cushion against the normal Yarmouth crop heat estimate.

Best for: specialty shape and display.

A specialty pumpkin chosen for shape and appearance, but it needs more season than the quickest pie types.

Tradeoff: More exposed than the quickest pumpkin choices.

Howden Mid-season
1300 GDD needed 1553 available before frost
April 28 October 24
Good fit
Why this fit?

Local season fit: Howden leaves about 253 GDD cushion against the normal Yarmouth crop heat estimate.

Best for: classic jack-o-lantern pumpkins.

A standard carving pumpkin that makes sense when the season has enough room for a more typical finish.

Tradeoff: Needs more season than smaller pie or mini pumpkins.

GDD comparisons are a planning shortcut, not a guarantee. Soil, watering, sowing depth, pests, transplant quality, and harvest goals still affect the final result.

Variety class Typical days to maturity Typical GDD need Local fit
Very early 85–95 1100 Good fit
Early 95–100 1200 Good fit
Mid-season 100–110 1300 Good fit
Late 110–120 1450 Workable

Main risk: The most common problems here are practical ones: planting too late, losing momentum early, or choosing varieties that ask for more season than necessary.

How Frost Affects Planting Dates for Pumpkin 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

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

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

The most common setbacks here are practical: planting too late, losing momentum early, or choosing varieties that ask for more season than necessary.

In Yarmouth, pumpkin usually has a solid seasonal margin when planted around May 8. 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 pumpkin, warmer garden spots usually improve early growth and can make timing a little more forgiving.

Set up pumpkin for strong vines and steady watering

The useful setup is about warm soil, steady water, and keeping vines growing cleanly.

Vine and fruit support

When the crop has enough season, the setup can focus more on clean growth and harvest quality.

Soil warmth

Warm soil still helps long-season crops start faster.

Early growth protection

Young vines still benefit from a warmer, cleaner start even when the overall season is workable.
