One of the most widely celebrated April fool’s jokes of all time was a story broadcast in 1957 on the highly respected BBC current affairs show ‘Panorama’ about the annual spaghetti tree harvest. The TV segment showed a Swiss family supposedly harvesting spaghetti from their own trees. The segment is now available to watch on YouTube (see below).

The joke fooled many and lots of viewers are said to have contacted the BBC for details on how to grow a spaghetti tree. While spaghetti is normally made from wheat flour and water mixed with egg, the ‘Panorama’ segment wasn’t completely barking up the wrong tree. It is possible to grow your own spaghetti on a vine, if not a tree.

The spaghetti squash is grown much like a cucumber and is closely related to zucchini. The vigorous vine produces large cylindrical fruit, which ripen to bright yellow.

When it is cooked (either baked, boiled or microwaved whole) the flesh can be scooped out in strings that resemble cooked strands of spaghetti. Serve with your favourite pasta sauce! Vegetable spaghetti is high in nutrients and low in calories.

Planting and growing

Plant the seeds of spaghetti squash in spring when the soil has warmed and all threat of frost has passed. Plant the seeds directly into a prepared a vegetable bed or plant into a large container (at least 40cm across or larger). As the vine sprawls much like a zucchini, space seeds at 1-1.2m apart so the vine has room to grow.

Like all cucurbits, spaghetti squash has both male and female flowers with the female flowers producing fruit. The vine takes around 15 weeks to produce mature fruit.

Harvest the large fruits that have turned bright yellow. Cut the fruit from the vine leaving a piece of stem attached. Kept watered, the vine should continue producing until the first winter frost. Plants may be attacked by powdery mildew towards the end of the growing season.

The fruit is also available occasionally in the fruit shop and keeps well wrapped in plastic and stored in the crisper section of the fridge.

I remember as a child being fascinated by the photos of spaghetti growing on trees at the Italian place in The Rocks in Sydney, can’t just remember it’s name. The walls were covered with the life-size scenes which made it seem very real – I really wondered if it could be true!

The Old Spaghetti Factory – it is now closed by was operating in the 1970s. Here’s a link to its early history from the archives of the City of Sydney.

No one sells spaghetti squash, too early in season, so i have grow my own plants and have some outside and some in greenhouse, where they are thriving like triffids .You tube showed me how to find male and female flowers which, with aid of cotton bud i have done the bees job.i now have
quite a few fruit now growing .Flowers seem to open up in morning and shut up in evening, when i water them . Might this just be this freak summer we are having.Can’t wait for full size squash as tried in America, really do taste better than spaghetti, roll out summer may be long time before another great summer
