Cucurbita spp.: In the diverse family of squash are true nutritional powerhouses, encompassing a wide array of forms, flavors, colorations, and culinary applications. Squash are rich in the carotenoids necessary for vitamin A production and boast a wide complement of amino acids. While starchy, most of the carbohydrates in the fruit come from special polysaccharides, pectins, which have exhibited strong antioxidant, anti-inflammatory, and anti-diabetic, insulin-regulating properties. Summer squash are a typically prolific garden classic.

CULTURE: Squash and pumpkins prefer good fertile soil and plenty of sunshine. Start indoors or in a greenhouse 3-4 weeks prior to your last frost. Sow in a 3 inch Peat or Cow Pot for direct transplanting. For best results transplant prior to the second set of true leaves. Plant the entire Peat or Cow Pot with no part of the pot exposed to the air. Work 1/2 cup of our complete fertilizer into the soil around each plant. For direct sowing, plant after your last frost and when the soil has warmed to at least 60°F. Sow with 3-4 feet between bush varieties, and 4-5 feet between vining varieties. Distance between rows: 6-10 feet. Squash need just-barely-damp soil to germinate. Too much moisture causes the seed to rot. All squash are monoecious (bearing separate male and female flowers on the same plant), and most require bee and insect activity for successful pollination. Poor fruit set is often the result of poor pollination.
INSECTS/PESTS: The major insect pests are the spotted and striped cucumber beetles, vine borers and squash bugs. Use row covers and/or apply Pyrethrin to reduce and control damage. Butternut varieties have a solid stem and are resistant to vine borer damage.
DISEASES: Squash are susceptible to a number of fungal, bacterial, and viral diseases that vary between regions. Your local county extension agent can help you pinpoint your particular problem.
HARVEST: Pick baby summer squash as well as the more mature ones. In general, summer squash are most tender and flavorful when very young. Winter squash are best left on the vine until fully mature. It should require quite a bit of pressure before your fingernail pierces through the rind into the flesh. For the best sugar content, cut the stem an inch or so from the body after the first light frost, and if the weather is dry, let them cure in the field. If temperatures drop below 25°F, bring your harvest inside and store in a cool dry location.
SEED SPECS: Minimum germination standard: 75%. Usual seed life: 3-4 years. Days to maturity: from date of direct seeding; if transplanting, subtract 10 days.

The first year we grew this unique squash we trained a vine to a trellis and while the plant produced many squash we enjoyed, the star was one that grew with gravity's help from the top of the trellis and it got over 4 feet long. We entered it in the state fair and won a first prize for most unusual vegetable! People thought it looked like a sitar.
Ripped it out

I grew this because a friend recommended it. Today I ripped it out. It is a huge vine, like a huge pumpkin; and the fruits are tasteless. Save space and plant real zucchini! If quantity is all you want, this is the variety you need. I think my friend was playing a joke on me. I am planning revenge!

Love it. Was looking for something vine borers would avoid and this did the trick. Love it pickled as well.
Nice squash for PNW

I grew this squash - under another name Trombetta di Abegna last year and it really produces a lot of fruit. Not as good for grilling as a regular zucchini but since all the seeds are in the ball on the end it is dense and solid - perfect for soups, steaming, etc. Vines get huge. We planted it again this year. I'd have bought the seed from TS if I had known they carry it.
