Where in Australia can I get marrow seeds from? You know, the big ones. I want to make some marrow rum as well as eat them.

I've tried to grow Spaghetti Marrow, was succesful with lots of greenery, strong vines and even flowers, but they just fell off without bearing any fruit at all! why?

Monica, this is usually due to poor pollination (it happens with Zucchinis too). Growing more than one plant can help or you shake the flowers or even hand pollinate with a small paintbrush once every few days (just wiggle it round inside the flower then move on to the next flower, etc).

I found a great video that addresses this problem at (look for it under zucchini)

Great question - I have been looking too. If you get an answer I would love to hear about it. :)
