Ratings & Reviews

Squash- TromboncinoSquash- TromboncinoSquash- Trom

Easy to grow (even for a beginner backyard gardener), vigorous and super high yield. It took a while to grow the seedling (from 5 seeds, I got 2 plants) but once they started, they just keep going. I water them regularly and feed every 4 - 6 weeks. They are 3 mths old now and so far still disease free. There is also a post about tromboncino in Theseedcollection website with hints and tips and I do follow them. When young (2 weeks old), the fruit tastes like white zucchini but with more flavour. Watch out for the sap, when harvesting the fruits. Overall, highly recommended and will definitely buy the seeds again
