Black Zucchini Summer Squash Seed

Black Zucchini summer squash is not black but a deep, dark green! (50 days) Black Zucchini is great for home gardeners who are looking for an open-pollinated zucchini with excellent flavor, but who don’t want record-breaking yields.

This seed was brought in from California in 1931 by the Jerome B. Rice Seed Co. of Cambridge, NY. Has firm, tender flesh with small seed cavities and its best picked around 6" long. The flavor was well above average in our taste tests. Open plant habit makes picking easy.

If you are concerned that it is blossoming without fruiting just remember that the male flowers start blooming about one week before the female flowers bloom in most squash varieties.

30 seeds per pack makes about 10 hills. Packed for 2017. Lot #381. 90% germination.

Cucurbita pepo

Culture: Tender, will not survive frost. Sow in hills 4' apart, 5 seeds/hill. Thin to 2?3 best plants. Floating row covers, especially when used in low tunnels, provide extra heat and can hasten maturity by 1 to 2 weeks.

Male blossoms typically precede females by about a week. Females have a bulge at the base of the blossom, an early stage of the fruit forming. In early summer, a combination of cool, cloudy weather and declining bee populations may result in poor pollination causing low yields.

Mites and colony collapse disorder have wiped out a high percentage of wild and domesticated honeybee colonies in the last 20 years, creating a real crisis for cucurbit growers. Don?t leave oversized squash on the vines. It shuts down production.

Make succession plantings to ensure harvest through the entire frost-free season, insurance against powdery mildew and other diseases tiring old plants. Minimum germination temperature 60°, optimal temperature range 70?90°, optimal temperature 85°.

Days to maturity are from direct seeding.

Taste: Unless you want to stuff them, for best flavor pick squash when they are small. Squash blossoms are a delicacy. Harvest male blossoms when fully open for salads or stuffing. Don't pick them all at once because you may not get squash at all!

Pests & Diseases: To combat squash bugs without using pyrethrum or neem: Protect young plants with row covers. Striped cucumber beetles and squash bugs overwinter in squash residues so burn or haul these away at season?s end rather than cold composting them. By hand-picking them in June and July, you can head off an endemic problem and almost completely eliminate squash bug damage.
