Burpee’s Butterbush

Burpee’s Butterbush Butternut OG

(87 days) Cucurbita moschata Open-pollinated. “Hands down the best” of the nine different butternuts Mark Fulford tried over the years. Smooth tan 2–3 lb fruits with small seed cavities and deep reddish-orange flesh are “as sweet as the best sweet potatoes.” Superior nutty flavor, moist but never watery—though not as moist as the larger butternuts. Its earliness is a boon in cold summers. Though named and classed as a bush butternut, more accurately they have determinate vines that can crawl up to 10' in good fertility. Still a big advantage where space is precious. Average yield is 3–5 ripe fruits per plant. Excellent keeper.

Additional Information

Butternut group

~280 seeds/oz, ⅛ oz packet sows 7 hills. Butternut was introduced in 1936 by Joseph Breck and Sons of Boston, out of Canada Crookneck, an 1800s variety. They are the best keepers and contain 30% more vitamin A than hubbards and 80% more than acorns.

Culture: The larger butternuts should be started indoors to mature in our climate.

Cucurbita moschata

C. moschata are usually smooth and tan. They are the squash of choice in Zones 6 and south because of their relative resistance to the squash vine borers that torment acorns and buttercups. See also 1740 Cheese Pumpkin.

Winter Squash

Culture: May be direct-seeded or transplanted. Direct seeding: Sow 4–5 seeds per hill when weather has warmed after danger of frost. Allow 4–6' between hills. Thin to 3 best plants. Use row covers and low tunnels to hasten maturity and reduce insect damage. Transplanting: Start indoors three weeks before setting out. Do not disturb the roots. Transplant bush varieties 18" apart, vining varieties 30" apart. Tender, not frost hardy. Heavy nitrogen feeders. Excessive heat and/or drought can prevent blossom set, reduce yields. Winter squash can take one or two light frosts on the vine. To improve flavor and storage, field cure for at least 10 days after harvest, covering if hard frost threatens. Store under proper conditions, at least 50° and 60–70% relative humidity in a place with good air circulation. Do not pile up squash. Inspect periodically and be sure to use damaged, stemless or small fruit first. Acorns have the shortest storage time before getting stringy, followed by delicatas, buttercup/kabochas. Minimum germination temperature 60°, optimal temperature range 70–90°. Days to maturity are from direct seeding.

Pests & diseases: BLR: Black Rot, PM: Powdery Mildew

Pest: Striped Cucumber Beetle
Cultural controls: use tolerant or resistant varieties, rotate crops, till under crop debris soon after harvest, use floating row covers until flowers appear, use plastic mulch, perimeter trap cropping (Black Zucchini and Blue Hubbard make particularly good trap crops), use yellow sticky strips, hand-pick early morning when beetles are very sluggish.
Materials: Surround, Pyrethrum (PyGanic), Mycotrol.

Pest: Squash Bug
Cultural controls: rotation, till in cucurbit debris before winter and plant a cover crop, boards on soil surface near squash will attract bugs overnight which can be killed, avoid mulching. Squash bugs lay their brown-brick red egg clusters on the underside of the foliage, often next to the central vein—destroy egg clusters on undersides of leaves.
Materials: Pyrethrum on young nymphs, AzaMax.

Pest: Squash Vine Borer
Cultural controls: butternut squash is resistant, maximas & pepos susceptible; rotation, plow in squash vine debris soon after harvest, use floating row covers, watch for wilting plant parts and destroy borer within.

Disease: Powdery Mildew
Controls: Use small plots to slow spread, plant indeterminate (viney) varieties, control weed competition.
Materials: sulfur and whole milk, mineral or other oils in combination with potassium bicarbonate, Actinovate.

Disease: Bacterial Wilt
Cultural control: Striped Cucumber Beetle is vector—control it; choose resistant varieties.
