How to Sow

  • Sow in fertile, warm soil after danger of frost has passed.
  • Sow seeds directly in the garden.
  • Give large-fruited pumpkins plenty of room to ramble.
  • For improved drainage sow in mounds, or hills, of soil 12 inches in diameter, 6-8 inches tall.
  • Sow 4-6 seeds in groups about 3 inches apart. Each group should be about 4-6 feet apart. Cover with 1 inch of fine soil and firm lightly.
  • Keep evenly moist.
  • Seedlings emerge in 7-14 days.
  • Do not plant pumpkins and other squash family crops in the same spot 2 years in a row.

How to Grow

  • Thin seedlings to 2-3 per group when they are 1-2 inches high
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
  • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1-2 inches of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
  • Pumpkins have both male and female flowers on the same plant. Male flowers will open first and the female flowers will open later. The female flower has a miniature fruit behind the blossom.
  • Do not move or step on vines as they are quite fragile.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • If you are trying to grow extra-large pumpkins, allow only one fruit per plant to mature.
  • Beds of vigorous, sprawling pumpkin vines can be bordered by corn, towering pole beans, sunflowers and other trellised or vine vegetables.

Harvest & Preserving

  • Pumpkins are ready to harvest when the rinds are hard and a rich shade of orange or white depending on the variety.
  • If a light frost kills the vines, the pumpkins are ready to harvest. Pumpkins are damaged by heavy frost.
  • Cut pumpkins from the vine with a pruning shears, leaving about 3 inches of stem attached.
  • Allow the pumpkins to cure in the sun for a week to harden skin.
  • Store pumpkins in a cool dry place.
  • Roast the seeds for a tasty snack.

Rated 5 out of 5 by from WOW Best pumpkin my daycare has ever grown. The leaves are as big as an adults head. We planted 3 hills and the entire back wall is nothing but pumpkin plants. We are trying to see how large the pumpkins will get. The first hill we will only allow 1 pumpkin to grow. The next hill (which is already saturated in flowers (it's the beginning of July), we are going to let 2 pumpkins per vine grow, and the third hill we are going to just let it develop without plucking any flowers off. The plants seem to be growing overnight, they are bigger every time we look at them. We won't be going to a pumpkin patch this year! The picture is from standing on the other side of the yard....

Rated 5 out of 5 by from Pumpkin, Big Max I bought these seeds from the local home improvement store. Planted the seeds late June and, without any help from anyone but Mother Nature, produced a 70lb., 62"cir., 23"H pumpkin! It took two people to carry it from the garden and weigh it! We are harvesting the seeds from this pumpkin to grow next year. My 9yr. son is so excited! So much fun to watch the daily progress! Some days it seemed to grow right in front of your eyes! Next year(2013)....a friendly family competition to see who can grow the biggest! Make sure you have PLENTY of room for the vines to grow....mine grew 20+ft.!!

Rated 4 out of 5 by from Monsters We had a blast growng these monsters. We directly sowed mid-May and thinned to 2 - 3 per hill and the result was about 1.5 - 2 huge pumpkins per plant. Made pumpkin pie and it was by far the best pumpkin I have ever tasted!!!!!

Rated 5 out of 5 by from prizewinner hybrid I saw the packet of seeds in the local store and deceided I was going to grow a pumpkin for my niece this year. I knew nothing about growing them, but didn't let that stop me. I had about a 5x15 piece of barren ground behind some large evergreen bushes on the fence line where cucumbers had grown well in the past, so I figured what the heck. I dug a 12" hole about 8" deep, dropped some potting soil in the poor clay ground and put 1 seed in about 2" deep. To my surprise, about a week later a plant popped up. I put up a little barrier to keep the rabbits away and it took off. About 5 weeks later I had a forest of green leaves and some flowers. The flowers kept dropping off for a couple weeks, until 1 finally turned into a little yellow pumpkin. It's been about 6 weeks and I have 1 beautiful orange pumpkin that is about 20lbs. I'm very happy with the results. I don't know if they get any bigger after they turn orange. It has been a very cool and dry summer. I have very poor soil, I didn't fertilize, and didn't water very much and I still got a nice pumpkin. There's nothing like a plant that gives results even after being neglected. This is a great plant for a novice. My niece can't wait for halloween so we can carve up "her" pumpkin.

Rated 5 out of 5 by from Healthy seeds! These pumpkins are growing so well. I am only keeping one per vine so they will grow big. The vine has cracked open, but it still healthy, so I guess its okay. This is the first time for me to grow these pumpkins and I am having a wonderful time watching them grow. Thanks burpee!

Rated 5 out of 5 by from Dude. WHOA. I wanted a big pumpkin this year, and I think I have it. Sadly, the cantaloupe and strawberry plants have been overshadowed by this wildly spreading pumpkin plant (duh) and have stopped producing, but that's my own fault for plunking this pumpkin seed right down in the middle of their bed. Whoops. The pumpkin has done really well so far. The ONE pumpkin. At first it had a hundred blooms and little starting fruits, but after the first one took off, a lot of the blooms and all the other little fruits have shriveled and fallen off. Otherwise the plant looks great. It's possible that the plant just needs more room to grow and the bed is restricting its root development. Whatever. I'm going to have one huge pumpkin for Halloween and will be able to flaunt it on my front porch. We're currently building a cart for it since it's way too big for me to pick up/carry already. SWEET.
