(Best months for planting Marrow in Australia - cool/mountain regions)


October: After risk of frost

  • Harvest in 90-120 days
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed.
  • Best planted at soil temperatures between 20°C and 35°C.
  • Space plants: 90-120cm

This looks like a large version of zucchini/courgette. Skin is light yellow or white. Grow on raised mounds of earth/compost. Mulch to retain moisture and reduce weed growth. Frost tender.

Powdery mildew can be a problem especially in humid weather.

Culinary hints - cooking and eating Marrow

Good, cut in thick slices, seeds removed and stuffed with mince or spicy vegetable mix then baked in the oven

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 www.thegardenguru.com.au (look for it under zucchini)
