Squash is one of the plants grown in the traditional Native American vegetable growing technique called the Three Sisters. The other two plants in the Three Sisters are beans and corn. Each plant had its role in this companion planting tradition. Corn served as a structure for the vining beans to grow up. Squash served as a ground cover to prevent weeds from growing. Beans provided natural fertilizer for all.

Planting Instructions:


Soil Preparation:

Choose the sunniest location in your garden area. To prepare soil, remove weeds, large rocks, and litter from the planting area. Add fertilizer and lots of organic material such as compost, leaves, or rotted hay over the planting area. Till to mix this organic material into the soil. Make hills or soil beds 4-6 inches high. This formation of ridges will help with drainage.


Start indoors 2 weeks before last spring frost before transplanting, or directly sow outdoors in the spring after all danger of frost has passed and the soil begins to warm. To plant, make 1 inch deep holes in rows or hills spaced 20 feet apart. Cover thinly with soil and water after planting. After the seeds come up and plants are 3-4 inches tall, thin to one plant per hill. Choose the strongest, healthiest plant. Opt to hand-pollinate the plants and to prune plants to grow one pumpkin per plant to increase the likelihood of developing bigger pumpkins. 

Planting Depth: 1 inch
Within-Row Spacing:
15 feet
Between-Row Spacing:
20 feet


Care During the Season:

Watering: Water plants at the base to prevent risk of diseases. If the weather is really dry, plants should be watered at least twice a week. Water very deeply to give pumpkins the best opportunity to grow.  
Weeding: Keep plants as weed-free as possible. Consider pruning all but the strongest vine and removing all female flowers after the primary vine is chosen to encourage largest potential growth of the pumpkin.

Fertilizing: Scatter a complete fertilizer into the garden area. Work into the soil and leave the surface smooth. Do not let fertilizer touch the plants. Water the plants after fertilizing. Consider adding rich compost daily for the best opportunity of growing the largest pumpkins.

Insecticides: Insecticides may be used to protect plants. Bt-based insecticides and sulfur are organic options that can be used for prevention. Sulfur also has fungicidal properties and helps in controlling many diseases. Larvae of the Squash vine borer are usually found inside the stem and cannot be controlled once they are inside the stem. Sevin® and Thiodan® can control for squash bugs. Pyrethrin and rotenone can control for the cucumber beetle. Before using a pesticide, read the label and always follow cautions, warnings and directions.

Diseases: Plants can get many diseases, especially when harvesting begins. Check the plants daily and if spots or mold appear, treat the plant with an approved fungicide. Neem oil, sulfur, and other fungicides may be used. Please always follow label directions.


Harvest pumpkins right before frost, when they are full sized, the skin is hard, and the pumpkin is pale-yellow to pale-orange-or-red. Old squash vines can be composted or worked in the soil well before the Spring planting season.
