I have beautiful zucchini plants with huge leaves, but very tiny, not flowering buds...Is there a vitamin deficiency going on? What to do?

These tiny ones seems are male, am not an expert, just guess related to tempure

try applying calcium nitrate to correct calcium deficency.

Hi, I have got one Zucchini plant where I am getting lots of male flower but not female flowers. I had some female flowers before and had couple of fruits from this plant. But now its producing only male flowers. Also too many leaves have come up in the plant and noe of the leaves are growing bigger, all the leaves are cramped in a short area. Do anyone know the reason for this? do i need to cut the leaves a little bit to allow growth for leaves? I have one more plant and thats doing well, regularly giving fruit.

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.
