Zucchini
Cucurbita pepo
Zones 7–13
Growing
Zucchini thrives when planted in warm soil after the danger of frost has passed. Because these plants spread low and wide, they can easily overwhelm a garden bed. To prevent issues with root rot, ensure your planting site is well-drained. If your garden has a history of poor drainage, using raised beds can help keep the root zone from becoming waterlogged.
Maintaining a clean garden is essential for preventing disease. After your harvest, be sure to clear away any decaying plant matter or old fruit from the garden bed, as leftover debris can harbor fungal pathogens that overwinter in the soil. Keeping the area around your plants free of weeds also helps reduce potential habitats for pests.
When it is time to harvest, do not wait for the fruit to become overly large or soft. For the best quality, pick the zucchini when it is at your desired size and firm. Unlike some other crops, zucchini does not continue to ripen once it has been removed from the vine, so frequent monitoring is necessary to catch them at the right moment. If you have an abundance, you can store the harvested fruit in the fridge or blanch them before freezing for later use.
