How to Grow a Giant Pumpkin

Growing your own giant pumpkin is easy and isn't much different than growing zuchini or other garden vegetables.  A giant pumpkin plant needs good soil, lightly moist soil (don't let me get too dry), lots of sun, a little fertilizer, protection from strong winds and protection from cold.  If you would like to know how to grow your giant pumpkin plant into a 500+ pound pumpkin watch this video by our dad, who has grown some of the largest pumpkins in Utah and Colorado. 

Pumpkin Seed Germination

We highly recommend watching this video open_in_new_window.png to learn how to start your seed.  One key to getting your pumpkin seed to germinate is to keep the soil lightly moist.  The biggest issues we see with germinating seeds tends to be with the soil being too moist.  Here are some tips:

  • Put the seed in a seed-starting mix just below the surface with the pointy end down.  Ideally you want to put the seedling in a pot that is relativley big because the roots grow fast on these plants.
  • Put the seed starting pot somewhere warm, ideally in a place that is 80-85 degrees.  A closet with a thermostatically-controlled space heater can work nicely until the seedling starts to pop up. 
  • When the plant starts to outgrow the pot and outdoor plant soil is 70 degrees, you're ready to plant. 
  • Gently remove the plant from its existing pot. If the pot is flexible, squeeze the sides gently until the soil loosens and the plant can be removed easily.
  • Pick a site with full sun and lots of space for sprawling vines. Set the plant in your hole. Refill the hole around the roots with soil until it is level with the surrounding area or just slightly higher and pat down firmly. Water until the ground is soaked -- add more soil as needed and pat down firmly once again.
  • Pumpkins are big, greedy eaters and they like very rich soil that is well-drained and not too soggy. We mix lots of compost and aged manure into the planting spot before we plant.
