Tivoli Hybrid Spaghetti Squash Seeds

Days to Maturity: 98 from direct sow

AAS Winner 1991

So high yielding and delicious it won an All-America Selection, Tivoli hybrid is a spaghetti squash that also may be picked young for use as a summer squash. The flavor is sweet and mild, the texture crunchy; it is a winning combination you will enjoy all season. And the best part, it has a bush habit just right for patio containers, where you can enjoy it up close.

These fruits are medium-large, oval, pale yellow, and packed with creamy "spaghetti". They weigh between 4 and 5 pounds, on average, and measure 9 inches long by 6 inches in diameter. Slice them in half lengthwise, steam each side, and fluff up the "noodles" with a fork. Your spaghetti squash is ready for sauce.

Tivoli hybrid is very short vined, with less space between fruit and a sturdy, upright habit. The plant will probably reach about 2 feet tall and may stretch 3 feet wide in containers. Very productive, it is the first-ever bush habit spaghetti squash. No wonder it won an AAS award.

Spaghetti squash is a winter variety, acquiring a very hard shell for long-term storage if you let it grow to full maturity. Tivoli hybrid, however, can be picked young for use as a soft-shelled summer squash. You never get overwhelmed by the harvest; you can pick just what you need, and let the rest keep growing.

Squash is very easy to grow, and part of the Three Sisters Native American companion planting. (The other two sisters are beans and corn). Give it sunshine, well-draining soil, and adequate water, and Mother Nature will do the rest.

Sow the seed 1 inch deep, thinning the plants to 3 to 4 feet apart in the garden.

From Squash casseroles and stuffed Zucchinis to Pumpkin pies and jack-o'-lanterns, these versatile garden favorites offer something wonderful for everyone! Their history is long and rich, and their potential as a food source as well as a beautiful fall-season decoration is unsurpassed.

Choosing a Variety: Squash & Pumpkins

Pumpkins and Squash offer a wonderful variety of colors, sizes, and shapes, providing you with many options as far as flavors and applications. You can grow Pumpkins that range from small to giant -- anywhere from about 2 pounds to 100 pounds or more! Some are better for eating while others are mainly used for decoration.

When you're deciding which Squash you want to grow, you can choose from a delicious selection of summer or winter Squash. The summer varieties (which include Zucchini) are best for fresh eating and quick harvests, while the winter ones are great for storing and baking.

When to Start Squash & Pumpkins

Pumpkins and Squash are best direct sown outdoors after all danger of frost has passed in the spring and the soil has warmed. They can be sown indoors (at a temperature of 70 to 75 degrees F) 2 to 3 weeks before planting out, but direct sowing is recommended.

If you want Pumpkins for Halloween, plant from late May (in northern climates) to early July (in extremely southern locations). Keep in mind that if your Pumpkins are planted too early they may rot before Halloween.

How to Start Squash & Pumpkins

Pumpkins and Winter Squash:

Sow the seeds at a depth of 4 times the size of the seed, siting them in full sun in rich, sandy, well-drained soil. Fertilize before planting and then again every 3 weeks until you harvest. It's very important to keep the plants weeded and well watered. If you're growing your Pumpkins on hills, space the vines about 8 feet apart. If instead you choose to plant them in rows, space the vines 3 to 4 feet apart in rows that are about 8 to 12 feet apart. You can also grow them on a trellis, an option especially appealing if you have limited space. Expect germination in 7 to 10 days.

Summer Squash and Zucchini:

Sow the seeds at a depth of 1 to 1¼ inches, siting them in full sun in rich, sandy, well-drained soil. Fertilize before planting and then again every 3 weeks until you harvest. It's very important to keep the plants weeded and well watered. If you're growing your Squash on hills, space the plants about 4 feet apart. If instead you choose to plant them in rows, space the plants 2 to 3 feet apart in rows that are about 4 to 6 feet apart. Expect germination in 7 to 10 days and harvests in 40 to 50 days.

Special Considerations

Summer Squash can cross with similar varieties such as Acorn Squash and jack-o'-lantern Pumpkins. The cross-pollination will not be apparent with your current crop, but it's not recommended that you use the seeds for the following season. However, summer Squash will not cross-pollinate with Melons or Cucumbers.

If your summer Squash become too large (hard and seedy) they will sap the strength away from the plant that would otherwise be used to grow more fruit. Just throw away any that become too large.

Keep in mind that although squash plants produce both male and female flowers, it's only the Female flowers that produce fruit.

Vining Pumpkins need at least 50 to 100 square feet per hill.

Growing Tips for Squash and Pumpkins

• Squash do best in a well-drained, sandy loam that is high in organic matter.
• Pumpkins and Squash do not transplant easily. If you want to start your seeds indoors use paper containers or some other type of fiber material that will peel away from the roots without causing them any damage. Also, only have one seedling to each container. Peat pots are also good, as they can be planted as-is, thus minimizing root disturbance.

• Summer Squash can be planted any time after there is no longer a danger of frost -- from early spring until midsummer.
• Summer Squash will produce excellent yields in any well-drained soil.
• Harvest your summer Squash when they're small and tender. They can over mature rather quickly since they develop so rapidly after pollination, so check your crop frequently in order to pick them at their peak quality.
• Elongated varieties are best at 2 inches or less in diameter and about 6 to 8 inches long. The smaller "Patty Pan" types are best at 3 to 4 inches in diameter.
• If your Squash does get too large it can still be used for things such as stuffing or grating into breads and other dishes.
• Summer Squash develop very quickly and are ready to pick within 4 to 8 days of flowering. This is especially true in hot weather.
• Take care when harvesting your Squash -- they can bruise and scratch easily, and the leafstalks and stems are prickly, so they can irritate unprotected hands and arms. Wear gloves and harvest with pruning shears or a sharp knife.
• Storing your summer Squash: place unwashed fruit in plastic bags in your refrigerator's crisper. Use within 2 or 3 days for best quality.
• The open blossoms (before the fruits appear) are also edible -- they're delicious dipped in batter and fried.

Winter Squash:

• Harvest the fruits when the rind becomes hard and they're a deep, solid color.
• You will want to harvest most of your crop before heavy frosts, in September or October.
• When cutting from the vine, leave about 2 inches of vine attached to the fruit.
• If the fruit becomes cut or bruised or they are subjected to heavy frosts, use them as quickly as possible or compost them -- keep an eye out for seedlings in your compost pile!
• Winter Squash should be stored in a dry area that stays between 50 and 55 degrees F. If you need to store them for an extended period of time place them in a single layer, preferably not touching each other. This reduces the chance of spreading rot.

Pumpkins:

• Use a sharp knife or pruning shears to harvest, leaving 3 to 4 inches of stem attached to the fruit.
• Handle and store as you would other winter Squash.

Pests and Problems to Watch For

Powdery mildew:

• Plant resistant varieties whenever you can.
• If you can avoid it, don't apply nitrogen fertilizers late in the season. This will limit the production of succulent tissue, which is the most susceptible to infection.
• Avoid overhead watering.
• Remove and destroy infected plants -- DO NOT compost them!
• Allow for as much air circulation as you can.

Squash bugs:

• Choose pest-resistant varieties when possible.
• Early detection is very important, so look over your plants often.
• If only a few of your plants are infected, you can just collect and destroy the bugs and their egg masses. Boards, shingles, or something similar can be placed on the ground near the plants -- the bugs will often concentrate themselves to that area.
• You can cover the vines until blossoming begins, at which time they'll have to be uncovered for pollination.
• Burn or compost plant debris at the end of the season.
• Chemical insecticides can be used if nothing else works. Follow all label directions and safety precautions.

Cucumber beetles:

• Choose pest-resistant varieties if possible.
• Plow early to remove vegetation and discourage egg laying.
• Sandy soils aren't usually as susceptible to pest problems.
• Row covers can keep them off until the plants are well established.
• You can apply a foliar insecticide at the cotyledon stage (the appearance of the first leaves). Be sure to follow label instructions and safety precautions.

Squash borers:

• After you harvest the fruit, destroy the spent vines to kill any larvae that may be hiding inside the stems.
• Plow in fall or spring to kill any cocoons that may have over wintered.
• Some gardeners like to plant a trap crop of very early-planted squash -- it can alleviate pest pressure on other, later varieties.
• You can remove the borers by hand by slitting the stem with a knife, removing the intruder, and then covering the slit area with soil, which will promote additional root formation. You can also pick the eggs off by hand.
• Place a barrier or cover over the stems to prevent the borers from laying eggs in the first place.
• You can catch and destroy the moths -- do this at twilight or in the early morning as they rest on the upper side of the leaf bases.
• Use an appropriate insecticide, but be sure to read instructions and advise on when to apply, as timing is crucial.
• Borers are quite susceptible to natural enemies, such as parasitic wasps, especially in the egg stage.

Cucurbita pepo produces the bushy Summer Squash, Zucchini, and the lesser-known Custard Squashes and Crooknecks. It also produces some of the vining winter squashes that are treated in a separate entry. The types treated here taste best when harvested immature, when the skin is easily pierced with the thumbnail. Pick them when ready in order to keep the vine producing new fruits

Superior Germination Through Superior Science

First of all, we have humidity- and temperature-controlled storage, and we never treat any of our seeds with chemicals or pesticides. Nor do we ever sell GMO's (genetically modified seeds), so you always know the products you're buying from us are natural as well as safe for you and the environment.

Superior Standards - University Inspected

Hand Packed By Experienced Technicians

When packing our seeds, the majority are actually done by hand (with extreme care!), and we often over-pack them, so you're receiving more than the stated quantity.

The Park Seed Gold Standard

Heirloom Seeds are open-pollinated -- they are not hybrids. You can gather and save heirloom seed from year to year and they will grow true to type every year, so they can be passed down through generations. To be considered an heirloom, a variety would have to be at least from the 1940's and 3 generations old (many varieties are much older -- some 100 years or more!).

Hybrid seed are the product of cross-pollination between 2 different parent plants, resulting in a new plant/seed that is different from the parents. Unlike Heirloom seed, hybrid seed need to be re-purchased new every year (and not saved). They usually will not grow true to type if you save them, but will revert to one of the parents they were crossed with and most likely look/taste different in some way.

The ancient Native American technique of growing Corn, Beans, and Squash together in an arrangement called the Three Sisters is the ultimate in companion planting and helps increase harvests, naturally!

Corn acts as a support for climbing bean vines, the beans fix nitrogen in the soil for the high feeding requirements of corn and squash, and the squash provides mulch and root protection for the corn and beans! After cooperating beautifully in the garden, corn and beans form a complete protein when eaten together! How's that for a mutually beneficial relationship?

The Three Sisters are all easy to direct sow in the garden and are a great project for children, teaching them about the beauty of natural harmony while providing a fast-growing reward for their efforts.

Make the best possible use of your garden space this season, and try growing the Three Sisters! Just follow the easy steps listed below, fertilize well, plant other companions like herbs to assist with pest control, and you'll be harvesting your best crop in no time!

In May or June when soil has warmed:

Shape a flat-topped circular mound of soil about a foot high and 2 feet across at the top, sloping outward toward the base. Plant a circle of corn seeds on top, about 5 or 6, and water them in well, tamping down your soil mound firmly so it doesn't wash away in the first rain. Space the mounds 3 or 4 feet apart in the garden.

Since all corn grows on sturdy, dependable stalks, the variety you choose depends on the flavor, disease resistance, and holding ability you want. Sugar Buns is a Sugar Enhanced (SE) yellow hybrid with absolutely scrumptious golden kernels and is positively scrumptious. For SE whites, you can't beat Silver Princess, with extra-long ears bursting with flavor. And for the sweetest ears yet, you absolutely must try Corn Mirai, available in Yellow, White, Bicolor, and even a Mini!

About two weeks later:

When your corn reaches about 5 or 6 inches high, plant Bean seeds (6 to 8 of them) around the edges of the flat top or about halfway down the sloping sides of the circular mound. Push the seeds down deep into the soil and, if you're planting on the slope, make sure the soil is nice and firm. Add a bit of Nature's Aid at planting time to help the Beans fix nitrogen.

To get your Beans to climb up the cornstalks, choose Pole rather than Bush varieties. Smeraldo is far and away the best-tasting Pole Bean, with flat pods up to 10 inches long on vigorous 4- to 6-foot vines. Park gardeners rave about Kwintus, a super-early performer with succulent pods on stringless 8- to 10-inch pods. And is the classic name in Beans, with top-quality dark green pods that are both stringless and fiberless, even if you pick them a bit late. We even have Blue Lake available in organic seed!

One week or so after that:

Plant Squash seeds around the base of the mound, on flat ground. You can make them radiate around the mound, or just go in the direction you have available space! 6 to 8 seeds in a ring around the base of the mound is usually plenty.

The traditional Squash family member for this Sister is Pumpkin, with its all-American flavor and long growing season. For a quicker harvest, grow Summer Squash varieties such as organic Early Summer Crookneck or Zucchini such as space-saving Eight Ball Hybrid.

When everything begins growing...

Thin the plantings to 2 or 3 Corn stalks, each with no more than 2 Bean plants winding around it. (You'll need to help the Beans get started growing up the stalks). The Squash is going to vine along the ground, so the number of plants you need depends on how far apart your mounds of corn and beans are, how long the vines get, and how much walking space you need in the garden.

Add a FOURTH sister: Sunflowers!

Sunflowers attract birds, thus tempting them away from your corn plants. They shade the vining bean plants while also adding support. Plus, they're beautiful! It's a win-win situation!
