Are you looking for zucchini?
Cucurbita pepo and Cucurbita maxima
Squash should be sown direct, after frost, as it needs a warm soil to germinate; in subtropical areas and tropical areas avoid sowing during periods of high humidity. Space 'hills' 1 m apart, add plenty of compost, sow 3-6 seeds 15-20 mm deep and thin to the 2-3 strongest. Keep the soil moist. It needs a rich, high in nitrogen, well-drained soil, preferred pH 6-7.5. Pick when about 15 cm long, the flowers are also edible. Plan for 2 plants per 4-6 people.

Squash 'Baby Green Hubbard' UT
Cucurbita maxima
A teardrop shaped squash, 17 cm long with a very dark green, warted rind and smooth, orange-yellow flesh. It has a sweet, nutty flavour. Fruit weigh up to 2.7 kg on compact vines. It is a good keeper and stores up to 6 months. Days to harvest: 95 - 105 days, harvest when the skin is fully coloured.

Chilacayote is widely grown as a vegetable in Mexico and South America. It grows like a pumpkin vine to 15 m long and forms roots in the leaf nodes. The melon-like fruit are large, round, green and white speckled. Highly productive vines produce fruit that can weigh up to 6 kg. The flowers, leaves and tender shoots are used as greens. Young fruit are eaten cooked, mature fruit are used in jams and confectionery. The protein-rich seeds are very nutritious. Vines are very hardy and disease resistant. The fruit stores for many months. Days to harvest: 80 - 120 days
This is a completely different plant to Jam Melon Citrullus lanatus syn. Red Seeded Citron, an ancestor of the watermelon.

SC455 (approx. 10 seeds per pkt.)

SS111 (approx. 20 seeds per pkt.)
The Three Sisters Garden
This is a traditional Native American planting method using an inter-crop of corn, beans and squash. This vegetable guild sustained the Native Americans both physically and spiritually. In legend, the plants were a gift from the gods, always to be grown together, eaten together and celebrated together. Each of the sisters contributes something to the planting. Together, the sisters provide a balanced diet from a single planting. As older sisters often do, the corn offers the beans needed support and are planted first. The beans, the giving sister, add nitrogen to the soil for the benefit of all three. The large leaves of the squash vines protect the threesome by creating living mulch that shades the soil, keeping it cool and moist and preventing weeds. In this case it needs to be a running squash, not a bush squash like zucchini. In North American the term 'summer squash' is used for zucchini and button squash that are thin-skinned and do not store well; 'winter squash' is used to describe pumpkins and thicker-skinned squash like 'Delicata' or 'Vegetable Spaghetti'. Good choices are smaller leafed and smaller vines of Butternut Cucurbita moschata, 'Delicata' or 'Vegetable Spaghetti' Cucurbita pepo rather than the biggest pumpkins Cucurbita maxima like 'Queensland Blue' and 'Australian Butter'. Together, the three sisters provide both sustainable soil fertility as well as a healthy diet.

Squash 'Gem' UT
Cucurbita pepo
A South African favourite, this winter squash resembles a dark green, round cannonball. It produces up to 8 squash per vine and stores for up to 4 months if fully mature.
In temperate areas sow spring to early summer. In subtropical and tropical areas it is unlikely to do well, as it is very prone to powdery mildew. Days to harvest: 90 - 100 days; younger ones can be harvested and eaten like zucchini.
SS238 (approx. 12 seeds per pkt.)
Squash 'Golden Scallopini' UT
Cucurbita pepo
syn. Yellow Bush Scallop Squash, Yellow Pattypan Squash
A rare squash that is an Italian heirloom, it produces delicious patty-pan golden yellow squash with scalloped edges. Flesh is white, with a fine-grained texture and nutty flavour. Days to harvest: 68 days
SS219 (approx. 20 seeds per pkt.)
Squash 'Spaghetti' / 'Vegetable Spaghetti' H OG
Cucurbita pepo
Grow your own low carb pasta!
This is an easy to grow squash; the fruits range in colour from creamy white to pale yellow; 22 cm long and weigh approx. 1.8 kg. This squash stores well, for up to 3 months. The pasta-like flesh looks like the real thing and is great topped with pesto or pasta sauce. Days to harvest: 88 - 110 days. Please note: this is an open-pollinated seed of no specific cultivar and it is a very different colour to the bright yellow F1 hybrid available in supermarkets.
SV102 (approx. 20 seeds per pkt.)
Squash 'Sweet Dumpling' UT
Cucurbita pepo
'Sweet Dumpling' is a small, teacup-shaped winter squash 10 cm in diameter with delicious, light orange flesh and sweet taste. The size is just right for a single serve; it can be baked whole or stuffed. The productive, medium sized vines produce 8 - 10 fruit per plant.

Q. Why don't my pumpkin, squash or zucchini set fruit?
A. The most obvious problem can be lack of bees. Many gardeners find they need to hand pollinate. To encourage a visit by bees, avoid using overhead sprinklers and any form of insecticide. Bees also do not like windy conditions.

There are a range of other factors that influence pollination and successful fruit set:
  • too much rich nitrogen fertiliser will cause leaf growth at the expense of flowering,
  • too high a summer temperature will do the same,
  • being stung by Cucumber fruit fly can cause tiny fruit to drop off the vine,
  • moisture stress will do the same, and
  • lack of calcium or boron will also cause young fruit to yellow and drop off.
At Green Harvest we are passionate about open-pollinated, heirloom seed as we believe it is a resource belonging to all people, not a product to be exploited by a few. Open-pollinated vegetable seeds are genetically diverse treasures that have been passed on from generation to generation of gardeners. We invite you to contact us if you would like to help us preserve open-pollinated seed varieties in Australia. More information on seed saving...
