How to grow Tromboncino Squash

A complete guide to growing Tromboncino Squash, sun requirements, when to plant, feeding, when to harvest and how to troubleshoot any problems you might have growing this tasty squash.

Tromboncino plants require a rich, well draining soil with plenty of compost mixed in.

Plant Tromboncino in a full sun position. 

No, Tromboncino is not frost tolerant. 

Plant Tromboncino roughly 60cm apart. 

Tromboncino is a warm season crop that is best planted in spring once the danger of frost has passed. 

Seeds are quick to germinate and can be direct sown once the soil has warmed to roughly 20°C (68°F).  

Feed your Tromboncino plant with a regular application of organic fertiliser throughout the season. 

Harvest Tromboncino at any size you prefer. You can harvest the young fruit when they are green and use the same way you would Zucchini squash, or wait until the fruit is large, orange and fully mature to be stored and used the same way you would use Butternut squash. Mature fruit is generally ready for harvest when it has completely changed from green to an orange colour and the vine that is attached to the fruit begins to brown and die back. 

Pests that affect Tromboncino include: Aphids, Slug, Snail, Army Worm, Spider Mites, Thrips, Cucumber Beetle, Cutworms, Flea Beetle, Leaf Miner, Squash Bug, Squash Vine Borer, Stink Bugs, 28 Spotted Ladybug. 

Diseases that affect Tromboncino include: Leaf Blight and Leaf Spot, Downy Mildew, Powdery Mildew, Fusarium Crown and Foot Rot, Gummy Stem Blight, Verticillium Wilt, Bacterial Wilt, Aster Yellows, Blossom-end Rot, Mosaic Virus, Phytophthora Crown and Root Rot. 

Tromboncino vines as well as their fruit will grow quite large. The vines benefit from trellising to allow room for the long fruit to hang freely. Tromboncino fruits can be quite heavy, so it's important that your trellis can handle the weight of the fruit.
