It’s a common myth that growing vegetables requires a lot of time, effort, expensive tools and even a greenhouse. Of course, it's perfectly possible to raise a garden of fussy veggies that need daily care, but there is a far easier way to grow your own: choose low-maintenance vegetable varieties that flourish even if you miss a day or two of care. Whether you're a beginner gardener or just short on time, selecting easy, speedy vegetables to grow will bring you tasty harvests in return for very little effort.

We're very familiar with ornamental plants that practically grow themselves, but vegetables? No plants can be completely neglected when you're growing vegetables, but some are far more forgiving than others. One of the most time-consuming chores is watering, and while all veggies need water, some types and varieties are naturally better at coping with hot weather, dry spells, and those days when you just don’t have the time – or will – to water.

These are fast-growing, heat-tolerant vegetables so can all be sown in July. The warm soil in summer will help seeds germinate quickly, so plants produce a good harvest before the growing season ends. That makes these vegetables a great choice for children to grow, too – or if you simply want to experience the childlike joy of an uncomplicated homegrown harvest. Here's our pick of easy-going veggies you can still sow in July.

1. Zucchini 'Black Beauty'

Zucchini is a classic summer veggie, known for its abundant production and mild, versatile flavor. ‘Black Beauty’ is one of the most dependable cultivars and, even in hot, dry weather, it still produces heavily. The large leaves shade the soil, keeping it a little cooler and helping retain moisture, enabling the plant to bounce back after a missed watering or two.

Ideal for zones 3 through 10, zucchini ‘Black Beauty’ seeds are available from Burpee. And it couldn't be easier to grow Black Beauty zucchinis. Sow seeds in soil in full sun, and make sure there is plenty of space between plants – while this variety only reaches a foot high, it can spread 5-7 feet (though this stem growth doesn't need to be over soil). Water deeply once or twice a week and your zucchinis should be ready to harvest about 50 days after sowing seeds, making this one of the best vegetables to sow in July. Harvest regularly while the fruit are still small (6-8 inches) for the best flavor.

2. Cucumber 'Armenian Dark Green'

‘Dark Green’ produces long, crisp cucumbers with no hint of bitterness. This is an excellent variety for a salad and for slicing to eat raw with dips, and is suitable for zones 2 through 10. The plants thrive in the heat of mid and late summer and grow readily and easily without too much intervention from you. The root system runs deep, so occasionally missing a watering won’t phase this cultivar.

Armenian Dark Green Cucumber seeds are available from Eden Brothers. Make sure you sow seeds in a spot with full sun and, if possible, provide a support for the vine to climb. While you can grow cucumbers along the ground, a trellis or fence keeps fruits out of the dirt and saves space. Water as consistently as possible and harvest the cucumbers when they are between 12 and 18 inches long, about 65 days after sowing the seeds.

3. Bush Beans 'Contender'

Growing bush beans is straightforward, and 'Contender' is a particularly forgiving variety as it will tolerate some dry periods. Forgetting to water this plant might slow production of tender, stringless bean pods, but it won't stop it altogether. ‘Contender’ is appropriate for zones 3 through 9.

Contender Bush Bean seeds are available from Eden Brothers. Direct-sow seeds for this bush bean in full sun, in the ground or a large container. Water regularly, but don’t worry if you do so imperfectly. Compared to other types, this variety continues to thrive in hot weather, and the beans should be ready in about 50 days after sowing. Harvest beans regularly to encourage more production.

4. Carrot 'Red Cored Chantenay'

When you're considering vegetables to sow in summer, don't discount carrots. 'Red Cored Chantenay' develops shorter roots than other cultivars, which makes it easier for new or time-pushed gardeners to get a good harvest, as the short length means they are less likely to turn out misshapen. This variety also has tops that tolerate heat well. An heirloom carrot variety, it has a sweet flavor and is great for eating raw and for cooking.

Red Cored Chantenay Carrot Seeds are available from Walmart. To grow carrots, sow seeds in place, either in the ground. Because of its shorter roots, this is also one of the best veggies to grow in containers for a productive kitchen garden on your patio. Suitable for zones 3 through 10, ‘Red Cored Chantenay’ does best in full sun or some dappled shade and with soil that stays consistently moist, especially in the seedling stage. While you’ll still enjoy a good harvest even with a little neglect, the best carrots develop with regular and consistent watering.

5. Okra 'Clemson Spineless'

Okra is an unsung hero of the garden, but if you learn how to cook this tasty veggie, you’ll benefit from a fast-growing plant that’s easy for beginners and busy gardeners to grow. The flowers are so pretty, too, and because the fruit pods grow vertically upwards, this is an attractive plant to have in your garden. It's a heat-lover, too, so this is one of the best vegetables to start from seed in July.

Even among other heat-loving okra varieties, ‘Clemson Spineless’ is extremely drought and heat-tolerant, thriving even if you neglect it a little or if the weather becomes unseasonably hot and dry. Clemson Spineless Okra seeds are available from Botanical Interests. Sow these okra seeds in a spot with full sun and water as regularly as possible. Grow okra and within 30 to 60 days, you’ll have tender young okra fruits to harvest. Okra is suitable to grow in zones 2 to 10, but hotter weather is best.

6. Pole Beans 'Rattlesnake'

Pole beans differ from bush beans in that they grow on a vine, and ‘Rattlesnake’ is a colorful variety of pole bean with pods striped in green and purple. Suitable for zones 4 through 10, this cultivar grows quickly, so you still have time for a good harvest this year.

It also forgives inconsistent watering better than other varieties, still providing a heavy yield, and Rattlesnake Pole Bean seeds are available from Eden Brothers. Sow seeds in full sun next to a support the vine can climb like a trellis, arbor, fence, or even patio banister. While it appreciates regular moisture, this pole bean will bounce back after short dry spells.

7. Black-Eyed Cowpeas

Cowpeas are easy to grow, and grow fast, with pods maturing in about 60 days after sowing. That cowpeas are often used as cover crops between growing seasons to maintain soil health and enrich it with nitrogen shows you how what a low-maintenance vegetable this plant is. But you can also grow this veggie for an edible harvest. Cowpeas grow in areas and conditions that are tough for other vegetables, and naturally form upright, bushy plants, so this is a great option for beginners and busy gardeners who want to be more hands-off.

Black-Eyed Cowpea seeds are available from Eden Brothers and you can grow cowpeas in zones 5 through 11 as they handle the heat of midsummer very well. You can harvest fresh pods or leave them to dry to use later. Sow seeds for cowpeas in full sun and water regularly until they get established. Then you can largely leave them alone, and the plants will still thrive.

Successful vegetable gardening isn’t about doing everything perfectly. Start with these forgiving varieties of tasty veggies and simply provide as much consistent care as you can. The plants will thrive and give you a good harvest, even when your care is imperfect.
