where do you get the seeds from a zucchini plant so you can replant them and grow more the next season

Inside the plant there are the seeds

i have never seen a better herb for attracting bees as a Borage plant and you can eat the flowers too.

Hi, my zucchini is a really light green colour - not anything like those you buy in the supermarket? Is this normal? Should we pick it and eat it

Ash, Zucchini come in various shades from yellow to almost black/green. Your light green ones are quite alright to eat. If they have small raised 'ribs' along the length of them, they are particularly good.

Hi! I'm having the same problem in Mt Helena wa. I think it's due to less bees because of the drought. That's my only suggestion! I've tried putting buckets of water around to attract them.

My zucchi plants grow enormous, flower copiously but then the fruit just shrivells away to nothing. I haven't had one fruit from either plant, despite about 10 flowers at a time per plant. I'm in Cottesloe, WA

An even easier way to hand-pollinate - pick the male flower, pull the petals away leaving the stem and the stamen (the long yellow bit sticking out of the middle of the male flower) and brush the stamen onto the stigma (the thing inside the centre of the bloom) of the female flowers. You can do the same with other cucurbits eg pumpkins, cucummbers. I do mine on the way out of the house in the morning. Cucumbers are a bit harder as the flowers are so much smaller - you might need a paintbrush for those!

Me too, Kate! I'm in Trigg and experiencing the exactly the same with my zucchini plants. I was told that my problem is a lack of bees for cross pollination between the male ans female flowers...

to hand pollinate: get a small soft paint brush, open the male flower gather pollen on brush then open female flower and light coat on the bit inside, you have now pollinated your zuchinni it should only take a couple of days to watch the zuchis grow, amazing!
