Butternut squash growing season takes approximately 110-120 days. Butternut squash generally has a long growing season, but if your local season is short, it’s best to start your seeds in the spring after the last frost has passed. “I always remind gardeners to be patient because butternut squash needs a full growing season to mature,” suggests Julia Hodges, a seasoned authority on plants, gardening, and growing food.
Their vines grow swiftly, but the squash takes three to four months to mature for harvesting from planting. Roasting, mashing, boiling, and more makes butternut squash much-loved and versatile in the kitchen, so it’s no surprise many gardeners are asking when to plant butternut squash in their home gardens.
Butternut squash growing season begins when any danger of frost is over, and the soil is sufficiently warmed by the sun to 60 to 65 degrees Fahrenheit. Butternut squash plants are highly delicate.

How and When to Plant Butternut Squash
Butternut squash are good veggies to plant in April, depending on your growing zone. Once the danger of frost passes, it’s time to plant your butternut squash seedlings in the garden.
Butternut squash is commonly planted in threes to form a hill in the garden. Make hills a minimum of 8 feet apart and amend with compost, manure, and other materials ahead of time.
Plant the seeds in clusters of four or five seeds 1/2 to 1 inch deep. Thin them to the variety’s recommended spacing interval when the seedlings appear.
The fruits forming on the vines do not require a trellis but place something beneath them to keep them from contact with the soil. Adding a platform creates a dry place for the fruits to sit and prevents them from rotting. Use wooden boards, flat rocks, blocks, or straw mulch to lay under them.

Butternut squash plants enjoy being in the sun, although they sometimes become overheated. It’s natural for the leaves to wilt a little in the afternoon during hot summer days, then recover once the sun goes down. If your plants aren’t reviving, try putting them in the shade in the afternoon.
Organic matter should be abundant in the soil, and it must drain effectively and be slightly acidic to neutral. Seedlings shouldn’t be left to dry out.
As the summer advances, the plants require even more water, and the vines get larger. Leaves wilt regularly in hot, dry weather, but they regenerate as the day progresses. If the plants’ leaves are wilted early in the day, water them immediately.
Fertilizing during Butternut Squash Growing Season
Butternut squash plants are heavy feeders. Begin with rich soil, then add organic compost or aged manure as a side dressing as they grow. Apply a manure tea or liquid fertilizer every two to three weeks to ensure your squash has all the nutrients required for a bountiful harvest.
Pour manure tea directly onto the soil to enrich it and support your butternut squash plants. Fertilize butternut squash plants regularly to achieve the best fruit growth and highest yields.

Thankfully, squash bugs are simple to address using a homemade insecticide that won’t hurt beneficial pollinators necessary to ensure male flowers and female flowers achieve pollination.
Powdery mildew is another common squash pest. Use neem oil to combat powdery mildew fungus in your garden. Neem oil is an effective management measure if applied as soon as the first indicators arise, which may appear as small white spots on butternut squash plant leaves. This natural fungicide kills powdery mildew spores.
To suppress powdery mildew spores, blend and spray all plant surfaces, making sure to cover every leaf. Use pruners to snip off dead or dying infected leaves and prevent fungal spore spread.
