Is Butternut Squash A Fruit or Vegetable? (How To Classify & Grow It)

Butternut squash is a fruit that belongs to the winter squash family, along with pumpkins.

Like all members of the cucurbitaceae family, butternut squash flowers are monoecious and bear both male and female flowers.

The differences between these types of squash center on fruit shape, size and color.

Despite the fact that butternut squash is a fruit, it can be classified as both a root vegetable and fruit. It is also known as winter squash. The butternut squash belongs to the Cucurbitaceae family. It includes many different types of plants, including cucumbers, cantaloupes, gourds, watermelon and what we know as zucchini.

Butternut Squash grows on vines that are supported by poles or trellises that are made of wood or metal. The female flowers of this plant are the ones that produce the seeds for reproduction so they should not be allowed to self-pollinate.

For pollination purposes you need at least two plants within 200 feet of one another with a pollinating variety growing somewhere in between. In order for the fruit to develop, the flowers have to be fertilized. This is done by planting a pollinator plant that has been around previously or can be purchased from a nursery.

The vines should be tied up along poles as soon as they appear and should start flowering within six weeks of being planted. Harvesting begins approximately 100 days after planting with early varieties and 150 days after planting with late varieties. 

The fruits are usually twirled onto a hook from the vine. This also can be done by cutting them free from their attachment point on the vine itself once ripe enough. Butternut squash should be stored in a cool dry place for about three months or longer if conditions were correct during the time of storage.

Some of the many varieties of butternut squash that are available include: The Long Island Cheese which is a good keeper and grows to be twelve inches long, the All American which can also be used as a pie pumpkin, and the Small Sugar which usually has a more tender flesh and cooks up very quickly.

If you decide to save seeds from your crop next year make sure you chop them up first before placing them in your container for storage. They require cold treatment for about three weeks and then can be stored at about 40 degrees Fahrenheit until use.

Butternut variety selection

Like other cucurbits, butternuts produce separate male and female flowers on the same plant; however, some varieties tend to be either predominantly male or female plants.

Therefore it is recommended to grow several vines together to maintain the fruit set. For this article we will use the designation “variety” for each member listed below, as they are considered separate varieties at present.

Varieties: ‘Connecticut Field’ or “Stokes” – a small, round fruit that is a pale yellow with a few dark green stripes. This variety matures early and produces mostly female plants.

‘Delicata’ – has an oblong shape with creamy white skin and orange flesh. ‘Delicata’ is one of the most popular winter squash varieties because it can be harvested as soon as 70-90 days after planting. It also bears predominantly female flowers, but does not reliably produce heavy yields of edible fruit like other varieties on this list

Golden Delicious Early Butternut – A medium size (8-15 pounds), bright golden colored fruit with grained, sweet orange flesh. This variety is a hybrid and one of the earliest to mature, bearing fruit in 90-120 days after planting.

‘Kemper’ – A medium sized (6 to 10 pounds), slightly flattened fruit that matures in about 100 days after planting. The color is pale yellow with a few green stripes along the length of its body.

Planting outdoors

Pick a location where you want your butternut squash plants to grow located in full sun for best yield production. Add several inches of compost to the soil and mix it in. Soil should be well-draining and loose, so that it can hold moisture for butternut squash vines.

Butternuts are long-season plants and need a minimum of 90 days to produce edible fruit. However, they typically take 100 or more days to reach maturity under normal garden conditions (80-90° F daytime temperatures). 

The recommended time for planting seeds outdoors is around May 15th; however, if you live in an area with mild winter weather (fall plantings) you could also plant as early as mid February. Seeds will rot in cold wet soils: wait until after the last frost date to begin your spring plantings outdoors.

Planting indoors

Seeds can also be planted indoors 4 to 5 weeks before the last frost date. If you live in a northern climate where nighttime temperatures drop below 50 degrees, protect your young plants from cold by enclosing them in a plastic plant tunnel or covering the entire row with a spun row cover supported by hoops.

Growing Conditions for Butternut Squash

Plant size: Vines grow up to 15 feet long and fruit production is higher on short vines which produce more runners than long vines, but longer vines make harvesting easier (the fruits are closer together)

Spacing: Plant seeds 2 inches deep; thin seedlings 12 to 18 inches apart, hills of three plants about 3 feet apart; hills of four plants about 3 feet, 4 inches apart; hills of five plants about 4 feet apart.

Temperature: Butternuts require an average soil temperature of 65°F degrees for best germination

When to water: keep the soil evenly moist with good drainage

Watering tips: use drip irrigation or soaker hoses instead of overhead sprinklers

Fertilizing: side dress your plants with compost tea at planting and again when fruits are beginning to form. Use a high nitrogen fertilizer twice during the season if you want larger fruit size. Stop feeding vines when fruit is set.

Pollination requirements

For pollination, butternuts need two compatible varieties planted within 50 feet of each other. One male flower from a different plant is required for every three to five female flowers. ‘

To ensure good pollination, plan on planting at least six vines of each variety you choose or make sure your local garden center carries plants that are already grafted and/or self-fruitful.
