What to Plant in June: 20 Crops for a Productive Garden

It's not too late to get started in the garden in June. June is a prime time for a highly productive second wave of planting. The soil has warmed, and frost is no longer a concern, so plants can establish quickly in the long days of early summer. It's a great month to sow seeds outdoors and start young plants into the ground.

Fast-growing vegetables, herbs, heat-loving crops, and succession plantings can all thrive when planted now. Both air and soil temperatures are high at this time of year, which will give crops a good start. Also, it's a great time to plant any tender crops and annuals still in the greenhouse, such as tomatoes, and to fill hanging baskets, raised beds, and containers with bedding plants. However, know that dry periods and drought can inhibit plant growth due to lack of soil moisture. Planting in June requires following crucial strategies to handle soaring temperatures and high evaporation.

Here we share the 20 best crops to plant right now in your garden, and essential June maintenance tips to keep your garden thriving through the summer heat.

Why June Is a Great Time to Plant

In June, warm soil temperatures are ideal for seed germination and root development. Warm-season crops grow rapidly, and many cool-season veggies can still be planted in northern regions or for late-summer harvests. In fact, June offers several benefits that you cannot get in March, April, or May. Here is why June is one of the best times of the year to plant seeds and starts.

• Faster seed germination due to warm soil temperatures.
• Robust microbial activity that makes vital nutrients immediately available to your young plants' root systems.
• Longer daylight hours encourage growth.
• The threat of frost is long gone, so there's no frost damage. You can plant sensitive, heat-loving crops without worrying about a sudden overnight cold snap.
• Opportunities for succession planting.
• Continuous harvests throughout summer and sweet, crisp, and flavorful fall harvests.
• Better growing conditions for heat-loving vegetables.

20 Crops to Plant in June for Maximum Yield

When planting in June, success hides in selecting crops that thrive under intense sunlight and warming soil temperatures. Before planting, consider your USDA hardiness zone and the average first frost date in your area. Most crops planted in June will have enough time to mature before fall arrives.

1. Bush Beans

Bush beans are among the easiest, fastest vegetables to grow in June. Unlike their pole-climbing cousins, bush beans stay compact and are ideal for filling gaps in raised beds.

They are the best crops to plant in June because warm soil speeds germination and gives you faster harvests. Beans love soil temperatures between 70°F and 80°F. You can sow beans directly into the ground in June. Varieties like 'Provider' or 'Early Bush Italian' will yield crisp, snap-ready pods in just 50 to 60 days.

2. Cucumbers

June is the prime time for cucumber planting. The soil in June is warm enough to support fast cucumber germination, within just 3-5 days. If you have tighter spaces or containers, choose compact bush varieties like 'Spacemaster 80' or 'Bush Champion'.

If you have a trellis or vertical A-frame ready, vining varieties like 'Marketmore 76' will quickly scale the support and keep the fruit clean, straight, and away from ground pests. The vigorous cucumber vines will thrive in full sunlight, warm soil, and consistent watering.

3. Zucchini and Summer Squash

Zucchini is an excellent addition to summer salads. Zucchini and yellow squash grow quite well when planted in June. All this summer squash needs to grow successfully is a warm, sunny location, consistent watering, and regular fertilization.

Zucchini is also highly prolific. Squash varieties like 'Black Beauty' or pattypan types thrive in the heat. They grow from seed to full maturity in roughly 45 to 50 days. Make sure to give them plenty of room, as a single healthy plant can spread up to four feet.

4. Corn

Corn is a versatile crop that's perfect for gardeners starting their summer planting a little later. It is a superior summer crop that requires warm soil to germinate without rotting.

Plant sweet corn in blocks rather than single long rows to improve pollination. Corn varieties like 'Ambrosia' or 'Honey Select' mature in 75 to 85 days, setting up a stunning late-summer harvest.

Tip: In USDA growing zones 8-10, cover your seeds with a row cover to prevent them from drying out.

5. Beets

Beets are cool-weather crops and are typically planted in cooler temperatures, but they'll germinate in soil temperatures from 50°F to 78°F. They surprisingly tolerate summer planting in early June. Beets offer a double harvest of earthy roots and nutrient-dense greens, so they're a two-for-one veggie. While they mature, you can cut off a few of their leaves and enjoy them in a salad. Both roots and greens are edible.

Why plant beets in June? Planting beets in June gives you summer harvests, crisp fall harvests, and multiple succession crops.

6. Pumpkins

If you want homegrown jack-o'-lanterns or pie pumpkins for Halloween and Thanksgiving, June is the perfect month. Pumpkins require a long, warm growing season of 90 to 120 days to reach full maturity.

Plant traditional pumpkin varieties like Connecticut Field or Howden, or the miniature variety 'Casperita' in metal raised beds to ensure proper drainage and maximum sun exposure.

7. Radishes

Radishes are also the fastest-growing vegetables to plant in June. While early spring radishes tend to bolt and turn woody in the summer heat, specialized heat-tolerant varieties can handle the June heat. Many radish varieties mature in just 25–35 days.

Look for 'French Breakfast' or the stunning, crisp 'Watermelon' radish. Sow them in the partial shade near taller crops like corn or tomatoes to keep the root zone slightly cooler.

Tip: Plant small amounts of radishes every week for continuous harvests.

8. Melons and Watermelons

From sweet cantaloupes to refreshing watermelons, these vining fruits love June planting conditions. Warm temperatures in June encourage strong vine growth. If you're in a northern region, grow short-season varieties like the compact 'Bush Sugar Baby' watermelon. It matures in around 75 days and fits comfortably into small backyard areas or large containers.

9. Carrots

Sowing carrots in June heat ensures a sweet, crisp harvest in fall. Plant carrots in June to enjoy fall harvests, sweet roots, and excellent storage quality.

You must know that the secret to summer carrot success is consistent watering. Keep carrot seeds continuously moist for 10 to 14 days to germinate. Cover the seeded rows with burlap or a row cover to lock in soil moisture until the first green seedling emerges.

10. Okra

Okra grows well in hot climates. Choose varieties such as 'Clemson Spineless' or the deeply pigmented 'Red Burgundy' that grow into beautiful, hibiscus-like ornamental shrubs. You can harvest the tender pods just 50 to 60 days after seeding. Keep checking the okra plants daily, as pods can become tough overnight.

June conditions are ideal for planting okra because:

• Soil is fully warmed
• Plants grow rapidly
• Production increases in heat

11. Swiss Chard

Lettuce may struggle and turn bitter when the heat of July arrives, but Swiss chard (Beta vulgaris var. cicla) remains strong. Swiss chard thrives during summer heat better than many leafy greens. Plant ornamental varieties like 'Bright Lights' in your summer garden to enjoy striking ribbons of yellow, pink, and crimson. Harvest the outer leaves continuously, as it is a "cut-and-come-again" crop, until hard winter frosts arrive.

12. Kale

Spring-planted kale can sometimes become tough and infested with garden pests like aphids. However, June kale planting offers you a premium autumn crop. In cooler regions, kale can be planted throughout June.

Opt for varieties like 'Lacinato' (also known as Dinosaur or Tuscan kale), which establish themselves during the summer and produce their sweetest, most tender leaves after the first autumn frosts.

13. Basil

Basil thrives when temperatures rise. It is a popular companion plant for tomatoes, both in the garden and on the plate. It is highly cold-hardy, so June is the safest and most rewarding time to direct-sow kale across the northern US. Harvest regularly to encourage more growth.

Planting basil in June provides:

• Fast growth
• Abundant leaves
• Fresh flavor all summer

14. Tomatoes

Many gardeners argue that your tomatoes should already be in the ground in June. However, if you're a tomato lover and you want to add fresh-grown tomatoes to your meals, you can still make it work by choosing the right varieties or planting seedlings instead of seeds. June is still a good time in many regions, especially when using tomato transplants. A wide variety of crops matures before the fall frost and provides continuous harvests. Keep in mind that they need consistent watering, lots of fertilizer, and regular pruning to thrive.

Choose disease-resistant varieties for the best results.

Tip: Choose small-fruited tomatoes, determinate, or early-maturing varieties so you spend less time waiting for them to grow on the vine.

15. Peppers

This is another popular vegetable that thrives in the warmth of summer. If soil temperatures are above 70°F, pepper is an ideal addition to your June planting list. Plant them in full sun and nutrient-rich soil for successful growth. Peppers mature between 65-120 days, but most varieties are ready for harvest around 75 days.

16. Southern Peas

Peas are usually grown in the early spring and are known for being a cool-weather crop, but if you're in the right zone and choose a heat-tolerant variety, you can add them to your summer garden. You can choose black-eyed peas, purple hull peas, or crowder peas, as these crops are excellent heat-producers. They contain deep taproots that make them highly drought-tolerant once established, and they naturally fix nitrogen into your soil.

Most pea varieties take around 60 to 70 days to mature. Make sure to improve the soil before you sow your peas by amending it with some compost or well-rotted manure.

17. Sweet Potatoes

June may be too late to plant traditional potatoes, but it is the absolute perfect window for sweet potatoes. They require warm soil and a long, hot growing season to develop their sweet, tuberous roots.

You should plant them using slips, which are rooted cuttings taken from a mature vine, rather than seeds. Plant slips in loose, well-drained soil and give them plenty of room for vines to spread and act like a living mulch that suppresses weeds.

18. Pole Beans

If you have planted your compact bush beans, use your vertical space with pole beans. Pole beans thrive in summer heat and produce over a longer period than bush varieties. They take slightly longer to start producing than bush beans, but they will continue to produce fresh pods continuously until the first fall frost.

19. Turnips

Turnips are another versatile crop grown for their edible roots and nutritious greens. So planting turnips in June gives you a delicious two-for-one yield in the autumn. Varieties like 'Purple Top White Globe' are famous for their spicy, nutrient-dense greens and their crisp, earthy root globes.

Plant turnips in June to enjoy:

• Quick growth
• Multiple harvest options
• Good fall storage potential

20. Asian Greens

Some quick-growing Asian greens can also handle a June planting if grown under the right conditions. Greens like Tatsoi or baby Bok Choy grow incredibly fast.

To succeed in June plant, them in a garden location that receives partial afternoon shade, such as the eastern side of your tall tomato cages or corn blocks and keep the soil consistently moist. You can begin harvesting tender baby leaves for stir-fries in less than a month.

June Gardening Tips

Follow these summer maintenance and June gardening practices to manage your garden in the heat and help your new plants thrive.

Give Deep, Consistent Watering

Summer temperatures can quickly dry out soil and evaporate moisture. Rather than watering lightly every day, provide deep, consistent watering that encourages roots to grow downward.

Aim to deliver one to one-and-a-half inches of water per week in one or two deep soakings. You can increase the frequency based on your plant's watering needs. Deep watering produces resilient, drought-tolerant plants.

Watering Tip: In summer, always apply water early in the morning, ideally between 5:00 AM and 8:00 AM.

Use Low-Evaporation, Smart Irrigation Systems

If you are still watering your vegetable garden beds and raised beds with overhead sprinklers, you are losing a lot of your water to wind drift and immediate evaporation. Install a water-efficient garden drip irrigation system to deliver water directly to plants' roots, minimizing waste from evaporation or runoff.

Use Clean, Ergonomic Garden Tools

June is a physically demanding month in the garden between planting, setting up heavy trellises, mulching, and handling stubborn weeds. So, protect your body from any injury using high-quality, ergonomic garden tools. Look for hand tools designed to maintain neutral wrist alignment. Choose lightweight, heavy-duty materials, such as forged aluminum, for trowels and pruners to reduce lifting fatigue.

Add Mulch

Mulching is one of the most important gardening tasks in June. Apply a clean, three-inch layer of organic mulch across all your vegetable beds. Keep the mulch an inch away from your plants' stems to prevent rot. Mulch is a protective, insulating blanket for your soil that retains moisture and regulates soil temperature. Use straw, shredded leaves, untreated grass clippings, or compost.

Feed Heavy Feeders

Fast-growing summer crops need nutrients to grow fully in the heat. In June, feed heat-loving vegetables such as tomatoes, cucumbers, peppers, summer squash, and corn with compost, organic fertilizer, or balanced vegetable fertilizer. Apply fertilizer according to directions on the package.

Control Weeds

Weeds grow rapidly during warm weather and compete with vegetables for water and nutrients.

Spend a few minutes each week in your garden specifically to pull weeds by hand, remove weeds using an ergonomic weeder, and mulch exposed soil. Regular garden maintenance prevents larger problems later.

Watch for Pests

Insect activity may increase in June due to active plant growth. So inspect plants frequently and use organic ways to address pest problems before infestations spread.

Common garden pests include aphids, cabbage worms, squash bugs, flea beetles, and tomato hornworms.

The Bottom Line

June can be an ideal time to plant certain vegetables, herbs, and fruits in your garden. The warm soil, lack of frost, and abundant sunshine in most regions can allow many plants to flourish quickly. If spring crops such as peas, spinach, or lettuce have finished producing in your garden beds, replant those empty beds with fast-growing summer crops like beans, cucumbers, squash, basil, and sweet potatoes. This simple gardening practice maximizes your garden productivity and keeps your harvest basket full throughout the growing season.
