How Many Pumpkin Plants per Square Foot?
1 pumpkin plant per 4 square feet: a 2 x 2 foot block with the plant in the center, so plants sit 24 inches apart. The vine is trained out of the bed, so the type you grow, bush or vining, decides how much open ground it needs beside the bed.
Pumpkin spacing in a square foot garden
| Per square foot | 1 plant per 4 squares (a 2 x 2 foot block), which works out to 0.25 plants per square foot |
|---|---|
| Inches apart | 24 inches, plant to plant |
| 4 x 4 bed (16 squares) | fits up to 4 plants (4 blocks) |
| 4 x 8 bed (32 squares) | fits up to 8 plants (8 blocks) |
| 3 x 6 bed (18 squares) | fits up to 3 plants (one block across the 3 foot width and three along the 6 foot length, with 6 squares left over) |
Those bed counts are grid maximums. They only work if every vine can leave the bed, and for vining pumpkins they are not realistic. University of Illinois Extension gives a single hill of vining pumpkins a minimum of 50 to 100 square feet, and a whole 4 x 8 bed is 32 square feet. In a 4 foot wide bed every 2 x 2 block touches a long side, so each vine has an edge to leave by. How many to actually plant depends on the type and on the open ground past that edge.
Why my chart says 4 squares and Illinois Extension gives a vining hill at least 50 square feet
They measure different things. My square foot gardening chart gives a pumpkin at least 4 squares and says to train the vine outside the growing area. Field spacing counts the vine too. Illinois Extension’s spacing by type:
| Type | Between plants | Between rows |
|---|---|---|
| Miniature | one plant every 2 feet | 6 to 8 feet |
| Bush | one plant every 3 feet | 4 to 6 feet |
| Semi-bush | hills 4 feet apart, 2 plants per hill | 8 feet |
| Vining | hills 5 to 6 feet apart, 2 or 3 plants per hill | 10 to 15 feet |
| Giant (jumbo) | 150 square feet per hill, thinned to 1 or 2 plants | |
In the Illinois table only miniature types, at 2 feet, match a 2 x 2 block. Bush types get 3 feet, a foot more than a block. West Virginia University Extension says compact bush-type pumpkins can tolerate 2 feet between plants and 8 feet between rows, which also matches a block. University of Minnesota Extension plants pumpkins 24 to 36 inches apart in the row, closer for bush types, with rows 5 to 6 feet apart, and suggests bush-type varieties for smaller gardens. The room between rows is where the vines go, and beside a raised bed that room is the path or the lawn.
Illinois Extension’s pumpkin variety list names Bushkin and Tricky Jack as bush types, Spirit and Sugar Treat as semi-bush types, and Baby Boo, Jack-Be-Little, Jack-Be-Quick, Munchkin and Sweetie Pie as miniatures.
How many fit along one side of a bed
This counts the same 2 x 2 blocks by type, at Illinois’ in-row spacing, along one long side of a bed with open ground beside it. Each block holds one plant, even where Illinois grows 2 or 3 plants to a hill. Blocks are measured center to center. On an 8 foot side, blocks centered 1, 3, 5 and 7 feet in are 2 feet apart, 1, 4 and 7 feet in are 3 feet apart, 1 and 5 feet in are 4 feet apart, and 1 and 6 or 7 feet in are 5 to 6 feet apart.
| Type (spacing) | 4 foot side | 6 foot side | 8 foot side |
|---|---|---|---|
| Miniature (2 feet) | up to 2 | up to 3 | up to 4 |
| Bush (3 feet) | up to 1 | up to 2 | up to 3 |
| Semi-bush (hills 4 feet) | up to 1 | up to 2 | up to 2 |
| Vining (hills 5 to 6 feet) | up to 1 | up to 1 | up to 2 |
A 4 foot wide bed has blocks on both long sides, so double the count if both sides have open ground. Each count needs open ground past the edge. The between-row spacing in the Illinois table above, from 4 to 6 feet for bush types up to 10 to 15 feet for vining types, is the room Illinois leaves for the vines. A 3 foot wide bed has room for one row of blocks along one side. Giant pumpkins are a different scale: Illinois gives them 150 square feet per hill, more than 4 times a whole 4 x 8 bed.
Planting the square
- Pick a 2 x 2 foot block on the edge of the bed with open ground beside it.
- Wait until the soil is 65°F at 2 inches deep, the mark Minnesota Extension uses for seeding vine crops.
- Sow in the center of the block, 1 inch deep, the depth Illinois Extension gives for every type. Illinois sows miniature types two or three seeds to a spot and thins to the best plant at the first true leaves, which leaves one plant in the block.
- If you set out a transplant instead, Minnesota Extension grows it in a pot at least 2 inches wide and deep for about 4 weeks, hardens it off, and plants it with 2 to 3 true leaves once the soil is at least 65°F.
- As the vine grows, guide it over the bed edge and away from the other squares.
When to plant pumpkins
The start indoors and transplant weeks are the ones the Plan My Garden planner uses, counted from your last spring frost. Turn the weeks into dates with the seed starting calendar, or enter your zip code on Plan My Garden to find your frost dates.
| Start indoors | 1 to 2 weeks before your last frost |
|---|---|
| Transplant out | 2 weeks after your last frost |
| Direct sow | No separate week in the planner. Minnesota Extension sows seed once the soil is 65°F at 2 inches deep, and Illinois Extension waits until all danger of frost has passed and the soil has warmed. |
| Days to maturity | about 100 days |
| Frost tolerance | Tender. Illinois Extension calls pumpkin a very tender vegetable whose seedlings are injured by frost. |
Starting seeds 1 to 2 weeks before your last frost and setting plants out 2 weeks after gives them 3 to 4 weeks indoors, close to the roughly 4 weeks Minnesota Extension allows from seeding to transplanting.
Soil temperature for germination
From my Seed Germination Temperature Chart: pumpkins germinate from 60°F, do best at 85-95°F, and the maximum is 105°F. Minnesota Extension waits for 65°F soil before it seeds or transplants pumpkins.
Growing notes
Minnesota Extension gives vine crops at least 1 inch of water a week. It uses a drip hose, a soaker hose or careful watering of the soil so the leaves stay dry, and no sprinkler. If you mulch with straw or compost, it waits until the soil is at least 75°F, because those mulches slow soil warming. Vine crops have roots close to the surface, so it cultivates shallowly and not too close to the plants.
The first blossoms often drop. Minnesota Extension says this is not a problem, because the first flowers to open are male. The female flowers open later and have a swelling at the base that forms the fruit.
Illinois Extension harvests pumpkins when they are a deep, solid color and the rind is hard, and cuts them from the vine with 3 to 4 inches of stem. Minnesota Extension picks them before a hard freeze and notes that a light frost that kills the vine will usually not harm the fruit.
Where to get seed
Wood Prairie’s organic pumpkin seed includes New England Pie (listed at 105 days with 4-6 lb fruit), Winter Luxury (105 days, vining plants with fruit that averages about 6 lb) and Howden (110 days, a jack-o-lantern type to 25 lb), plus Long Pie and Cinderella. New England Pie and Winter Luxury are the smaller fruit of the three, and Howden is the largest. None of the three product pages lists a bush habit, so plan on the vine running out of the bed. Code PMG5 takes 5 percent off.
Quick questions
How many pumpkin plants fit in a 4×8 raised bed?
Up to 8 on the square foot grid, one per 2 x 2 foot block, and only if every vine can run out of the bed. That maximum is not realistic for vining pumpkins: Illinois Extension gives one hill of vining pumpkins at least 50 square feet, and the whole bed is 32. At Illinois’ in-row spacing, each 8 foot side with open ground beside it fits up to 4 miniature or 3 bush plants.
What is pumpkin spacing in square foot gardening?
One plant per 4 squares, a 2 x 2 foot block, so plants are 24 inches apart and the vine is trained out of the bed. University of Minnesota Extension plants pumpkins 24 to 36 inches apart in the row, using the closer spacing for bush types, with 5 to 6 feet between rows. Beside a raised bed, the path or lawn stands in for that row space.
Can you grow pumpkins on a trellis in a square foot garden?
Miniature pumpkins, yes. Pie pumpkins, generally no. University of Minnesota Extension’s trellis guide says varieties with fruit up to 3 pounds work best, larger squash and pumpkins are too heavy to trellis, and trellised vines get the same spacing as vines on the ground. West Virginia University Extension lists miniature pumpkins at under 1 pound and pie pumpkins at 4 to 8 pounds, and Illinois Extension puts New England Pie at 2 to 5 pounds and Wood Prairie at 4-6 lb, which runs past that 3 pound mark. So a miniature can climb a trellis from its 2 x 2 foot block, while a pie pumpkin like New England Pie is better on the ground with its vine run out of the bed.
Should you start pumpkins indoors or sow them in the bed?
Either works. University of Minnesota Extension sows seed in the garden once the soil is 65°F at 2 inches deep, and uses transplants to help extend the season in northern Minnesota: seedlings about 4 weeks old with 2 to 3 true leaves, hardened off first. The Plan My Garden planner starts pumpkins indoors 1 to 2 weeks before your last frost and sets them out 2 weeks after.
Let the planner place them
Plan My Garden is free to start: enter your zip code, draw your beds, pick pumpkins and everything else you want to grow, and it places each plant at square-foot spacing and builds a planting schedule from your frost dates.
