Best Vegetables To Plant In July In New Jersey
When you plant in July, you are racing against the first frost date, which typically occurs in mid-October for most of New Jersey. You need vegetables that mature in 50 to 70 days. Some crops even prefer the cooler days of late summer and early fall. Here are the top performers for a July sowing.
Warm-Season Crops For A July Start
These vegetables love heat and will germinate quickly in warm soil. They are perfect for a mid-summer planting.
- Bush Beans: These are among the fastest producers. You can harvest them in just 50 to 60 days. Plant them in well-drained soil and give them full sun. They do not need much fertilizer.
- Summer Squash and Zucchini: These plants grow very fast. You will see fruit in about 50 days. Give them plenty of space and water deeply. Watch for squash bugs.
- Cucumbers: They love heat. Plant seeds directly in the ground. They need consistent moisture to avoid bitterness. Pick them when they are medium-sized for best flavor.
- Sweet Corn: If you have space, corn is a fun crop. It needs 60 to 70 days to mature. Plant in blocks for good pollination. Water well during dry spells.
Cool-Season Crops For Late Summer And Fall
These vegetables prefer cooler weather. You can start them in July for a fall harvest. They often taste sweeter after a light frost.
- Carrots: Sow seeds directly in loose, sandy soil. They take 60 to 70 days. Keep the soil moist for good germination. Thin seedlings to avoid crowding.
- Beets: Both the roots and greens are edible. They mature in 50 to 60 days. Soak seeds overnight to speed up germination. Harvest when roots are golf-ball sized.
- Kale and Swiss Chard: These leafy greens are very hardy. They grow well in heat and cold. You can start picking leaves in 40 days. They will produce until a hard freeze.
- Turnips: Fast and easy. They are ready in 40 to 50 days. Plant them in full sun. The roots are mild and the greens are tasty.
- Radishes: The quickest crop. Some varieties are ready in 25 days. Plant them in rows and harvest as soon as they are big enough.
Herbs That Thrive In July
Herbs are also great for a July planting. They do not take up much space and add flavor to your meals.
- Basil: Plant seeds or transplants. It loves heat and full sun. Pinch off flowers to keep leaves growing.
- Cilantro: It grows fast but bolts quickly in heat. Plant it in partial shade. Harvest leaves often.
- Dill: Direct sow seeds. It attracts beneficial insects. Use leaves fresh or let seeds form for pickling.
Preparing Your Garden Bed For July Planting
Soil preparation is key for a successful late-summer garden. The soil is warm, which helps seeds germinate fast. But it can also dry out quickly. Here is how to set up your bed.
Test And Amend The Soil
Before planting, check your soil’s pH. Most vegetables prefer a pH between 6.0 and 7.0. Add compost to improve fertility and water retention. A 2-inch layer of compost mixed into the top 6 inches works well.
Watering Strategies For July Heat
July in New Jersey can be hot and humid. Water deeply in the morning. This helps plants survive the afternoon sun. Drip irrigation is ideal. It keeps water off the leaves and reduces disease. Mulch around plants with straw or grass clippings to keep soil cool and moist.
Provide Shade If Needed
Some crops, like lettuce and spinach, do not like intense heat. You can use shade cloth to protect them. Or plant them on the north side of taller crops like corn. This gives them afternoon shade.
Step-By-Step Guide To Planting In July
Follow these steps for the best results. Timing and technique matter.
- Choose Your Crops: Pick vegetables that mature in 60 days or less. Check the seed packet for “days to maturity.”
- Prepare The Soil: Remove any old plants and weeds. Add compost and a balanced fertilizer. Rake the bed smooth.
- Sow Seeds Correctly: Plant seeds at the depth listed on the packet. In hot weather, plant a little deeper to keep seeds moist.
- Water Gently: Use a fine spray to avoid washing seeds away. Keep the soil moist until seedlings appear.
- Thin Seedlings: Once plants have two true leaves, thin them to the correct spacing. Crowded plants do not produce well.
- Fertilize Lightly: Side-dress with compost tea or a balanced fertilizer after three weeks. Do not overdo nitrogen on fruiting crops.
- Monitor For Pests: Check leaves daily for bugs. Use insecticidal soap or neem oil if needed. Remove diseased plants right away.
Best Varieties For New Jersey’s July Climate
Not all varieties are equal. Some handle heat and humidity better. Here are top picks for the Garden State.
Bush Beans
Try ‘Provider’ or ‘Contender’. They are heat-tolerant and produce heavy yields. They mature in about 50 days.
Summer Squash
‘Yellow Crookneck’ and ‘Black Beauty’ zucchini are reliable. They need consistent watering to prevent blossom end rot.
Cucumbers
‘Marketmore 76’ is disease-resistant. ‘Suyo Long’ is a good choice for pickling. Both do well in New Jersey’s summer.
Carrots
‘Nantes’ and ‘Danvers’ are sweet and grow well in heavy soil. ‘Parisian’ is a round carrot that grows fast.
Beets
‘Detroit Dark Red’ is a classic. ‘Golden’ beets are milder and do not bleed. Both mature in 55 days.
Kale
‘Lacinato’ (dinosaur kale) is heat-tolerant. ‘Red Russian’ is tender and sweet. Both survive light frosts.
Common Mistakes When Planting In July
Avoid these errors to keep your garden productive.
- Planting Too Late: Check your first frost date. Do not plant crops that need more days than you have left.
- Overwatering: Wet soil can cause root rot. Water deeply but less often. Let the top inch dry out between waterings.
- Ignoring Pests: July brings flea beetles, aphids, and squash bugs. Act fast if you see damage.
- Skipping Mulch: Bare soil heats up and dries out fast. Mulch keeps roots cool and reduces weeding.
- Not Succession Planting: Plant a few seeds every two weeks. This gives you a steady harvest instead of one big glut.
Succession Planting For Continuous Harvest
Succession planting means sowing new seeds every few weeks. This works great for fast-growing crops like radishes and beans. For example, plant a row of bush beans on July 1, then another on July 15. You will have fresh beans from August to October. The same goes for lettuce and spinach, though they need shade in July.
Dealing With July Heat And Humidity
New Jersey summers can be brutal. High humidity promotes fungal diseases. Here are tips to keep plants healthy.
- Water At Soil Level: Avoid wetting leaves. This reduces mildew and blight.
- Space Plants Well: Good air circulation prevents disease. Follow spacing guidelines on seed packets.
- Use Row Covers: Lightweight fabric can protect seedlings from intense sun and pests.
- Harvest Regularly: Pick vegetables when they are ripe. Overripe fruit attracts pests and slows production.
Fertilizing Your July Garden
Plants need nutrients to grow fast. Use a balanced fertilizer like 10-10-10 at planting time. For leafy greens, use a nitrogen-rich fertilizer. For fruiting crops like tomatoes and squash, use one with more phosphorus and potassium. Apply liquid fertilizer every two weeks for container gardens.
Pest And Disease Management
July gardens attract many pests. Here are common ones in New Jersey and how to handle them.
- Flea Beetles: They make small holes in leaves. Use diatomaceous earth or row covers.
- Squash Bugs: Check undersides of leaves for eggs. Remove them by hand. Use neem oil on nymphs.
- Aphids: They cluster on new growth. Spray with water or insecticidal soap.
- Powdery Mildew: White powder on leaves. Improve air circulation and avoid overhead watering.
- Tomato Hornworms: Large green caterpillars. Pick them off. Beneficial wasps help control them.
Harvesting Tips For Late-Summer Vegetables
Harvest at the right time for best flavor. Beans should be picked when pods are firm and snap easily. Zucchini is best at 6 to 8 inches long. Cucumbers taste better when medium-sized. Carrots can be harvested as soon as they are big enough to eat. Kale leaves are tender when small. Pick outer leaves first to keep the plant producing.
Extending The Season Into Fall
You can keep your garden going after September. Use row covers or cold frames to protect plants from early frosts. Hardy crops like kale, Brussels sprouts, and parsnips can survive light freezes. Plant them in July for a fall harvest. You can also grow garlic in October for a summer harvest next year.
