A fun variety of squash to grow is the spaghetti squash. While it grows like any other member of the squash family, spaghetti squash is unique in that when you cut it open, rather than slicing it into pieces, you’ll find strands and strands of material that resemble long, thin spaghetti noodles. An easy plant to start from seed, the “noodles” of your spaghetti squash can be cooked and enjoyed with your favorite pasta sauce.

Loosen the soil in your garden with a shovel by digging down 8 inches and bringing the lower soil up to the top. Turn the soil a few times to mix the soil well.

Use the hoe to build up small hills 4 feet apart. The hills should be 6 to 8 inches high with a shallow trench, or basin, running around the base in a circle.

Plant four or five seeds into each hill 1 inch deep, spacing the seeds out 3 to 4 inches apart. Thin each hill to only the two strongest seedlings after the seeds have germinated.

Water the planted seeds only enough to dampen the soil without eroding the hill. Maintain a moist hill for the first few weeks as the seeds sprout.

Fill the basin around the hill with water once or twice a week as the plants get bigger to give the squash enough water to grow without wetting the plants’ leaves or stems.

Place wood planks under the growing squash to keep it from resting on the ground. Harvest the squash when the fruits are small.


Things You Will Need

  • Garden gloves
  • Shovel
  • Hoe
  • Spaghetti squash seeds
  • Water
  • Wood planks


  • If you want to give your squash an extra boost, apply a low-nitrogen 5-10-10 fertilizer to the soil following manufacturer's instructions before planting your seeds. This can also be achieved by adding well-rotted manure to the soil during Step 1.


  • Only grow as many plants as your family needs, typically one or two plants per household member, but no more than eight plants. All squash is known for heavy productivity and you may find yourself with more squash than your family can consume or store.
