A: You can pick them off and drop them in a jar of soapy water, or you can spray the underside of the leaves with a mixture of vegetable oil and water.
Q: How do I stop my zucchini fruits from getting so big?
A: You can tie the stems to a small stake to give the fruit some support as it grows. This will also help to keep the fruit off the ground. The bigger the fruit is when it is mature, the riper it will be and more likely to have bugs.
Q: What can I do to make sure my zucchini fruits ripen at the same time?
A: You can cover some of them with a paper bag to help them ripen more quickly.
Q: How do I store my ripe zucchini fruits?
A: They can be kept for several weeks in a cool location such as a garage or basement.
Q: How long will zucchini seeds keep before they no longer grow?
A: Zucchini seeds can last up to 3 years if stored in cool, dry place.
Q: Which is better, an open pollinated zucchini or a hybrid?
A: An open-pollinated zucchini will grow well in almost any circumstance. A hybrid may grow more readily if you give it optimum care and pest control.
Q: What causes my zucchini plant leaves to have round yellow spots?
A: This could be due to either insects or disease. If it is due to insects, you should see evidence of them on the leaves. Look closely for tiny holes from leaf-eating insects such as the moth or pumpkin and vine worms which are lime-green in color and resemble tiny worms.
Q: Why are my zucchini fruits withering on the vine before they ripen?
A: This could be due to several reasons. They may not be getting enough water. The soil should be moist at all times. They may be getting too much water. Zucchini fruits grow best in a dry climate.

A: You forgot to plant the male zucchini somewhere in your garden or you destroyed all of the male flowers.
Q: What causes my zucchini fruits to have white spots on the skin?
A: This is a sign of a disease and the fruit should not be eaten.
Q: Why are my zucchini fruits splitting open?
A: This happens when the growing zucchini is given too much water.
