More Details

Squash 'Tromboncino' is one of the most multi-purpose plants we grow – it's a good ornamental climber, shaped like a trombone, has good mildew resistance, is good to eat small (as a courgette) and ripens and stores once large (as a winter-storing squash). Unusual – grow for the weird veg in your village show – and incredible for its versatility.

Genus Cucurbita pepo
Variety Tromboncino
Type Half-Hardy Annual Climber
Common Name Summer squash
Soil Type Fertile
Site Full Sun, Shelter
Moisture Moist but Well-drained
Height 90-120cm (36-48in)
Spacing 60cm (24in) apart in each direction when the plants have 5-6 leaves.
Sowing, Seeds, Planting Soak seed overnight and sow under cover from late March- April. Push seed, on its side (to prevent it rotting), 2-3cm deep into a 9cm pot of compost. Can be sown direct after last frosts, from May to June.
Care Tips Feed well with plenty of organic matter. Pick fruit regularly to prolong the harvest. This variety is ideal for growing up a trellis or archway (which will make the fruit grow straighter).
Harvesting Late June to October. The fruits are best at about 25cm long, but can grow up to 1 metre!
Cooking Notes Perfect for grilling, roasting, frying, or eating raw in salads.

These tiny seedlings arrived wrapped in paper and wilted. I managed to revive them and they eventually grew and fruited. I emailed feedback and was sent 3 more dry wilted seedlings. Not using lots of plastic is a good thing but a small wrap of foil would not have gone amiss

I bought 3 of these plants and put them in a newly broken bit of ground, in soil half and half with home made compost. They have a sturdy 5 foot hazel frame to climb. I now need a machete to get through them to pick the fruit! I run a cafe and we have had courgettes to feed every customer all summer. I am now growing them on to harden as winter squash. They certainly loved this summer's heat, they have not been so successful in previous years.

Tromboncino - super squash!

Grew 6 of these last year up and over a rose arch with tagetes linnaeus underneath. Just beautiful! Not only does the foliage and huge flowers look lush and almost tropical, but the fruits store really well for winter and are superb in stews and soups seasoned with some warming spices.
They are obviously hungry plants so I would say using planting pockets with lots of well rotted manure dug in is a must, and to mulch with garden compost to reduce moisture loss is certainly worth the effort.
Another added bonus is that as long as you train and tie them in as they grow the fruiting stem grows thick enough to hold the weight of the large fruit - which saves a lot of flaffing around, having to support the fruit with old tights as you have to do with some winter squash grow vertically, which is quite ungainly and not ascetically pleasing in the garden. I can't praise this squash plant highly enough, especially with its double function of being like a courgette when small and yet being a winter squash and storing so well. If one can only grow one squash then this is it, I'm just ordering more to grow over a pergola this year. Happy days!
Thank you Sarah for introducing me to this super squash!

Fun but not always successful in northern climes ...

This will be my forth year of growing Tromboncino: I really enjoy growing them and they look great climbing up wigwams or the wall. But for me (in a walled garden in a chilly Scottish glen) the amount of fruit I get is very variable - sometimes not much at all - but always delicious when I do.

This is my third year of growing Tromboncino courgettes and the best one yet!! My monster measures 103cm and keeps growing; even though I let them grow big they're still very tasty. I shall submit the latest photo on your Facebook page.
