3. Planting Multiple Times
One of the great things about zucchini is that it grows pretty quickly. It is ready for harvest just about 40 to 60 days after it has been planted. This means that if you want a really big harvest you can start new plants two or three times each season.
Zucchini plants work really hard at producing fruits, it is natural that the plants will then slow down and then give out. For this reason, it is a great idea to have a new crop that comes in just as the older plants are dying out. Some people feel like their first harvest of zucchini is plenty.
However, if you want a steady supply, the best thing to do is to plant in succession. Since zucchini is easily grown from seed, you do not need to start the seeds indoors ahead of time. You can sow the seeds directly and see plants within just a few days.
A second planting during the middle of July or August will grow faster and should produce in just a month.
