If you’re searching for the best vegetables to plant in august in kansas, you’re in the right place. August planting can feel tricky, but with the right choices, you’ll enjoy a bountiful fall harvest.
Many gardeners think August is too late to plant anything. That’s not true. The key is selecting vegetables that thrive in warm soil and mature before the first frost. Kansas’s growing season extends into October or even November, giving you plenty of time.
Let’s break down what works best. You’ll find practical tips, planting dates, and care instructions. No fluff—just actionable advice.
Best Vegetables To Plant In August In Kansas
When you think of August planting, focus on two groups: fast-growing warm-season crops and cool-season vegetables that can handle the heat. Here’s a detailed list of the top performers.
Warm-Season Vegetables For Late Summer
These vegetables love heat and mature quickly. They are perfect for August sowing.
- Bush Beans: Plant bush beans directly in the soil. They mature in 50-60 days. Choose varieties like ‘Provider’ or ‘Contender’. They handle heat well.
- Summer Squash: Zucchini and yellow squash grow fast. Plant seeds 1 inch deep. Harvest in 45-55 days. Keep picking to encourage more fruit.
- Cucumbers: Pick slicing or pickling types. They need warm soil to germinate. Plant seeds 1/2 inch deep. Mature in 50-70 days.
- Sweet Corn: Yes, you can plant corn in August. Choose early-maturing varieties like ‘Early Sunglow’. Plant in blocks for good pollination.
- Southern Peas: Black-eyed peas and cowpeas thrive in heat. They are drought-tolerant. Mature in 60-70 days.
Cool-Season Vegetables For Fall Harvest
These crops prefer cooler weather but can be started in August. They will mature as temperatures drop.
- Carrots: Sow seeds directly. They need loose soil. Mature in 60-80 days. Harvest after frost for sweeter flavor.
- Beets: Plant seeds 1/2 inch deep. Both roots and greens are edible. Mature in 50-70 days.
- Turnips: Fast-growing. Harvest roots in 40-60 days. Greens are ready in 30 days.
- Kale: Direct sow or transplant. Kale gets sweeter after frost. Mature in 50-70 days.
- Swiss Chard: Heat-tolerant. Harvest outer leaves. Mature in 50-60 days.
Leafy Greens And Herbs
These are excellent for August planting. They grow quickly and provide continuous harvest.
- Lettuce: Choose heat-tolerant varieties like ‘Buttercrunch’ or ‘Red Sails’. Plant in partial shade if possible. Mature in 45-60 days.
- Spinach: Sow seeds 1/2 inch deep. Spinach bolts in heat, so plant in a spot with afternoon shade. Mature in 40-50 days.
- Arugula: Fast-growing. Ready in 20-40 days. Great for salads.
- Cilantro: Plant seeds every 2 weeks for continuous harvest. Bolts quickly in heat.
- Dill: Direct sow. Mature in 60-70 days. Attracts beneficial insects.
Why August Planting Works In Kansas
Kansas has a unique climate. Summers are hot, but fall is mild. The soil stays warm, which speeds up germination. Cooler nights in September reduce stress on plants.
Another advantage: fewer pests. Many insects decline in late summer. You’ll deal with less squash bugs and cucumber beetles. Also, weeds grow slower.
Watering is crucial. August is dry. Use drip irrigation or soaker hoses. Water deeply in the morning. Mulch around plants to retain moisture.
Soil Preparation Tips
Before planting, prepare your soil. Remove spent crops. Add compost or aged manure. Till lightly. Test soil pH if possible. Most vegetables prefer pH 6.0-7.0.
- Clear the area of weeds and debris.
- Add 2-3 inches of compost.
- Mix well into the top 6 inches of soil.
- Rake smooth for even planting.
- Water the soil a day before planting.
Planting Techniques For August
Direct sowing is common for August. But some crops benefit from transplants. Here’s a simple guide.
- Direct Sow: Beans, corn, carrots, beets, turnips, radishes, peas.
- Transplant: Broccoli, cauliflower, cabbage, kale, Brussels sprouts.
- Either: Lettuce, Swiss chard, spinach, herbs.
For transplants, start seeds indoors in July. Or buy seedlings from a nursery. Harden them off before planting.
Step-By-Step August Planting Guide
Follow these steps for success. Adjust based on your specific location in Kansas.
Step 1: Check Your Frost Date
Kansas’s first frost varies. Northern areas see frost in early October. Southern areas in late October. Check your local extension office. Count backward from frost date to determine planting windows.
Step 2: Choose Your Vegetables
Select from the list above. Focus on what your family eats. Plant a mix of warm and cool-season crops.
Step 3: Prepare The Garden Bed
Remove old plants. Add compost. Level the soil. Create rows or raised beds. Ensure good drainage.
Step 4: Plant Seeds Or Transplants
Follow seed packet instructions for depth and spacing. Water immediately after planting. Keep soil moist until seeds germinate.
Step 5: Provide Shade If Needed
August sun can be intense. Use shade cloth for tender seedlings. Or plant in areas with afternoon shade. This prevents heat stress.
Step 6: Water Consistently
Water deeply 2-3 times per week. More if temperatures exceed 90°F. Check soil moisture with your finger. Water when top inch is dry.
Step 7: Fertilize Lightly
Use a balanced fertilizer. Apply at half strength. Too much nitrogen leads to lush leaves but few fruits. Side-dress with compost mid-season.
Step 8: Monitor Pests
Watch for aphids, flea beetles, and cabbage worms. Use insecticidal soap or neem oil. Handpick larger pests. Encourage beneficial insects.
Specific Vegetable Recommendations For Kansas
Not all varieties perform equally. Here are top picks for Kansas conditions.
Beans
Bush beans are best. ‘Provider’ matures in 50 days. ‘Contender’ is heat-tolerant. Plant every 2 weeks for continuous harvest.
Carrots
‘Danvers’ and ‘Nantes’ types do well. Sow seeds 1/4 inch deep. Thin to 2 inches apart. Keep soil moist for good root development.
Beets
‘Detroit Dark Red’ is reliable. ‘Golden’ beets are milder. Soak seeds overnight to speed germination. Harvest when 1-2 inches wide.
Kale
‘Lacinato’ (dinosaur) and ‘Red Russian’ are cold-hardy. Plant in full sun. Harvest outer leaves. Frost improves flavor.
Lettuce
‘Buttercrunch’ and ‘Romaine’ handle heat. Plant in partial shade. Use row covers to keep soil cool. Harvest leaves as needed.
Radishes
Fastest crop. ‘Cherry Belle’ matures in 22 days. Plant every week. Great for kids. Harvest when roots are 1 inch.
Spinach
‘Bloomsdale’ is heat-tolerant. Plant in late August for fall harvest. Use shade cloth. Harvest before bolting.
Common Mistakes To Avoid
Even experienced gardeners make errors. Here’s what to watch for.
- Planting Too Late: Check days to maturity. Add 14 days for fall slowdown. If it won’t mature before frost, skip it.
- Overwatering: August heat causes evaporation. But overwatering leads to root rot. Water deeply, not frequently.
- Ignoring Soil Temperature: Use a soil thermometer. Most seeds need 60-85°F. Carrots germinate best at 70°F.
- Skipping Mulch: Mulch keeps soil cool and moist. Use straw, grass clippings, or shredded leaves. Apply 2-3 inches.
- Not Thinning Seedlings: Crowded plants compete for resources. Thin carrots to 2 inches apart. Beets to 3 inches.
Fertilizing And Watering Schedule
Consistency is key. Here’s a simple schedule.
| Week | Action |
|---|---|
| 1-2 | Water daily if no rain. Keep soil moist. |
| 3-4 | Water every 2-3 days. Apply light fertilizer. |
| 5-6 | Water deeply twice a week. Side-dress with compost. |
| 7-8 | Reduce watering for root crops. Continue for leafy greens. |
Adjust based on rainfall. Use a rain gauge. Overwatering is more harmful than underwatering.
Harvesting Tips For Fall Vegetables
Harvest at the right time for best flavor. Here’s when to pick.
- Beans: Pick when pods are firm and snap easily. Don’t let them get too large.
- Carrots: Harvest when tops are 1/2 to 1 inch wide. Loosen soil before pulling.
- Beets: Pull when 1-2 inches. Larger beets can be woody.
- Kale: Harvest outer leaves. Leave center to grow. Stop picking after hard frost.
- Lettuce: Cut entire head or pick outer leaves. Harvest in morning for crispness.
- Radishes: Pull when 1 inch. They get pithy if left too long.
- Spinach: Harvest whole plant or cut leaves. Use before bolting.
Extending The Growing Season
Kansas fall can be unpredictable. Use these methods to extend your harvest.
- Row Covers: Floating row covers protect from light frost. They add 2-4 weeks.
- Cold Frames: Simple boxes with glass or plastic tops. Keep plants warm at night.
- Mulch Heavily: Thick mulch insulates roots. Use straw or leaves.
- Choose Cold-Hardy Varieties: Some vegetables tolerate frost. Kale, spinach, and carrots improve with cold.
