Butternut Squash Tromboncino


We love this pale green, Italian heirloom butternut squash here at She Grows Veg. Clearly given its name from the shape it grows into, akin to a trombone, this is a climbing squash that grows brilliantly over an arch, just mind your head! Can be eaten young and tender like a firmer courgette, or left to fully mature and stored for a year or more in the right conditions.

Average 15 seeds.

Sowing info

Squash are very fast growing and will quickly become large plants, so do not be tempted to start too early. Sow seeds 1.5cm deep in small pots filled with peat free compost. Sow the seeds on their side, if laid flat, water can sit on top of the seed and cause it to rot. Keep at a temperature of 20-25C until after germination, which usually takes 7-10 days.
