how many zucchini would give me a constant supply of zucchini.Do they need any special requirements?

Gareth, We usually have about 3-4 zucchini plants for the 3 of us with plenty to give away to friends. You should get your fill of zucchini slice, stuffed zucchini etc... and you will probably be glad to see the back of them until next season... Make sure you check them every day because a little one can become a massive marrow in 1 or 2 days.

I have grown zucchinis up here before without a problem but this time the fruits are getting stung by something. It leaves a few small brown spots on top and lays maggots inside. I can only use half the fruit after I cut away the bad bits.

My zucchinis are getting stung by something. It lays a maggot into the fruit on the top so I usually only get to eat half after I cut away the bad bits.

Does anyone know why my Zucchinis might have white spots on the leaves? Does not appear to be a pest and last season the same thing happened to a fully grown crop which then died.

Hi I'm a newbie. I have been told that you need 2 zucchini plants to get fruit is this correct?

Peit, No that is not true - one zucchini plant will produce fruit.

I have planted zucchini's and they are flowering. However the flowers then die and drop off. There is no sign of any fruit. Is this normal? Thanks

This year my zucchinis are growing only to the size of my little finger then dying off. Is the soil lacking something?

Billie, and Bridget, your zucchini are dropping off because they are not pollinated. You can help pollination with a soft paintbrush if there are not many insects around.

I am having trouble with rot on my zucchini as soon as the vegetable starts to develop. Do you have any ideas.
