The Essential Guide to Growing Zucchini

Referred to as zucchini in the US and Italy, this is perhaps the best known and most popular of the summer squashes. They come in many shapes and a variety of colors. Courgette is the French term for zucchin,i and people in the UK normally refer to courgette as vegetable marrow. The most prevalent courgettes are a long green oblong shape that resembles a cucumber.

Zucchini is a member of the melon and cucumber family. A prolific vegetable, the zucchini offers cooks great diversity in recipe applications including desserts, breads and casseroles.

The zucchini is treated as a vegetable in the culinary context, meaning it is usually prepared as a savory dish or side. In a botanical sense, the zucchini is actually an immature fruit - the swollen ovary of the female zucchini flower.

Those new to planting this vegetable have little to fear as they are easy to care for. These summer squash take up a fairly small amount of space and if kept picked will produce in abundance right up to frost.

Environmental Conditions

As mentioned previously, zucchini is a warm weather vegetable, so it dislikes cold and frost. Apart from that, it can grow just about anywhere, provided you give it as much sun as possible. Limited shade is ok if you live in a very hot climate.

Preparing the Garden Soil

As with any crop, you may want to know your current benchmark for minerals and nutrients in your soil. Grab a test kit at your local hardware store, or bring a soil sample to your county extension office. You want the pH near 6.0, with a good-draining soil mixture.

This fruit likes to be planted in a mound so prepare your garden soil in mounds of 2 feet in diameter. Build an 8" deep indention so the water drains to the center. Well-rotted manure can be added to the soil before building up the mound.

Planting Your Zucchini Seeds

Once you’ve built up your hills, plant 3 seeds in each mound, about 6 inches apart. Zucchini plants are vines, so they need a large area to grow properly. After you see some germination, you can start thinning to 2 or 3 plants per mound. Unfortunately, uprooting the plant will disturb the other plants nearby, so it’s not practical to transplant from your original grouping. Simply snip the unwanted plants at the base to give the others more room.

If you live in a frost zone, start your seeds indoors in a room that stays above 60 degrees F. Place the seeds 4" apart, moving the growing container to a full sun location. Within 10 days you’ll see the first signs of seedlings sprouting. Transplant these when they reach 3 inches tall. If you’re starting your zucchini gardening with seedlings, give them at least 12" space between the plants and the rows for adequate growth.

If you reside in a cooler climate, placing black plastic bags over the garden area before sowing your seeds or transplanting seedlings can help warm the soil. After a few days of sun, the black bags will absorb the sunlight and transfer the heat to the soil, as well as trapping that warm air right near the ground. Look for a soil temperature of about 70° degrees. Once the soil foundation has warmed up, add some dark-colored mulch. This helps maintain and insulate the warmth much in the same way your black bags do.

The Harvest

Your zucchini should be ready to harvest in less than 2 months. Be very observant once they have started blooming. In general, the sweetest flavor and softest consistency comes from small zucchini, so you’ll want to harvest early. As a bonus, this tells the plant to put more energy into fruit production, so you can get even more zucchini! On subsequent harvests, it’s best to let the zucchini grow to 6 inches long. Large squash are good for flavoring bread or even as a serving container.
