These big, fast-growing plants need plenty of moisture and lots of food. Grow them in rich, well-drained soil in full sun. Dig finished compost or well-rotted manure into the beds, and dig in 1 cup of complete organic fertilizer beneath each transplant. Water the soil around them when you irrigate, and always avoid overhead watering, as wet leaves will attract diseases like mildew. Keep weeded. Misshapen or withered fruits can result from incomplete pollination. Make sure to remove these from the plants as you see them, before they begin to rot, and put them in the compost. In the home garden it can be tempting to over-plant zucchinis. One well-grown plant will provide enough fruits for the average family. Instead of planting several zucchinis, use that space for other vegetables.
