Success growing backyard pumpkins

July 17, 2008

Last year we tried to grow pumpkins and failed miserably. Admittedly, the attempt was half hearted. The planting bed was hard-packed clay in an area that was formerly used for storing pipe. I dug deep holes and filled them with planting mix and compost, but the resulting vines were spindly and produced a small, thin crop.

Our first try at Big Max (Giant), Lumina (White), and Jack-Be-Little (Miniature) produced only a few little pumpkins. I blamed the poor production on the lack of bees, but after the changes we made this year, I can say that the bees were not totally to blame.

After making the changes below, I am happy to say that we have a strong crop of pumpkins this year and daily visits by the local bees. We’ve never been more excited to see bees in the garden.


If you want to grow pumpkins in your backyard, try these 6 steps:

  1. Full sun. We planted our pumpkins in the same spot this year because it gets full sun all day long. It has a southern exposure and is the warmest and sunniest spot in our yard.
  2. Raised bed. This year I built a 4ft x10 ft box and filled it with 6 inches of “garden mix” from the local landscape yard. In large beds, always add a few stepping stones or boards to walk on so that you won’t compact the soil. Pumpkins like to root their vines into the soil as they grow, which provides more nutrients to the plant and, more importantly, the pumpkins! A raised bed creates the perfect environment.
  3. Drip irrigation. Pumpkins like water…lots of it…and at regular intervals. I recently read about a woman who lost her prized Big Max pumpkin when it received a large amount of water all at one time and swelled to the point of cracking. Our drip system is on a timer so the pumpkins get a daily dose of H2O.
  4. Mulch. We added a 2 inch layer of shredded cedar mulch to the raised bed once the plants were about 4 inches tall. This serves two purposes: (1) Moisture is retained in the soil and is less likely to dry out on hot days and (2) the pumpkins have a dry surface on which to grow. If pumpkins come in contact with damp soil for an extended period they can discolor and, in the worse cases, soften and rot.
  5. Flowers and Bees. Pumpkins need bees. Bees like flowers. Attract bees to your pumpkin patch and your flowers are more likely to be pollinated. We planted a row of sunflowers along the back of the box, along with zinnias, marigolds, and rosemary, but the pumpkins grew faster than expected. There are pumpkins on the vine but no sunflowers yet (we’ll plant them earlier next year). Other bee-friendly flowers that we have in the yard include azalea, rhododendron, rose, thyme, red apple, agapanthus, lobelia, lavender, columbine, cosmos, daisy, pansy, primrose, lamb’s ears, sage, poppy, basil, boysenberry, orange. Check out this list of bee-friendly flowers for ideas.
  6. VF-11. We apply VF-11 plant food weekly. This stuff is incredible, and seems like magic. Buy some and use it on all your plants.
