Georgia’s long growing season allows for two separate squash plantings—one in spring and another in late summer. Knowing the best time to plant squash in georgia is key to getting a big harvest without pest or heat problems.
You can grow summer squash like zucchini and yellow crookneck, or winter squash like butternut and acorn. Each type has a slightly different ideal planting window. This guide covers everything you need to know for successful squash planting in Georgia.
Best Time To Plant Squash In Georgia
The absolute best time to plant squash in Georgia depends on your region and the type of squash. For most of the state, spring planting happens after the last frost date. Late summer planting is for a fall harvest.
Here is a quick breakdown:
- Spring planting: Late March to mid-April for south Georgia. Mid-April to early May for north Georgia.
- Late summer planting: Late July to mid-August for most areas. This gives squash time to mature before the first fall frost.
Soil temperature is more important than the calendar date. Squash seeds need warm soil to germinate. The soil should be at least 60°F (16°C) for summer squash and 70°F (21°C) for winter squash.
Regional Planting Dates For Georgia
Georgia has three main climate zones. Your exact planting window changes based on where you live.
North Georgia (Mountains And Foothills)
North Georgia has cooler springs and earlier fall frosts. The last spring frost usually occurs between April 10 and April 20.
- Spring planting: Mid-April to early May. Wait until the soil warms up.
- Late summer planting: Late July to early August. You want at least 60 days before the first fall frost (usually mid-October).
Central Georgia (Piedmont Region)
Central Georgia has a milder climate. The last frost is typically around March 25 to April 5.
- Spring planting: Early April to mid-April.
- Late summer planting: Early August to mid-August.
South Georgia (Coastal Plain)
South Georgia has a long, warm growing season. The last frost is often in mid-March or earlier.
- Spring planting: Late March to early April.
- Late summer planting: Mid-August to late August. You can plant later because the first fall frost is usually in November.
Why Soil Temperature Matters
Squash is a warm-season crop. It does not like cold soil. If you plant seeds in soil that is too cold, they will rot or germinate slowly.
Use a soil thermometer to check the temperature at a depth of 2 inches. For best results:
- Summer squash: Soil temperature of 65°F to 75°F.
- Winter squash: Soil temperature of 70°F to 85°F.
If you do not have a thermometer, wait until the soil feels warm to your hand. Another sign is when night temperatures stay above 55°F consistently.
Spring Planting Guide For Georgia Squash
Spring is the most popular time to plant squash. The weather is warming up, and the days are getting longer. Follow these steps for a strong start.
Preparing Your Garden Bed
Squash needs full sun and well-drained soil. Choose a spot that gets at least 6 to 8 hours of direct sunlight each day.
- Clear the area of weeds and grass.
- Loosen the soil to a depth of 12 inches.
- Mix in 2 to 3 inches of compost or well-rotted manure.
- Squash likes a soil pH between 6.0 and 6.8. Test your soil and add lime if needed.
Planting Seeds Or Transplants
You can plant squash seeds directly in the ground or use transplants. Seeds are cheaper and easier for most gardeners.
Direct seeding steps:
- Make mounds or hills about 12 inches wide and 6 inches tall. Space mounds 3 to 4 feet apart for summer squash. Space them 4 to 6 feet apart for winter squash.
- Plant 3 to 4 seeds per mound, about 1 inch deep.
- Water gently after planting.
- After seedlings appear, thin to the 2 strongest plants per mound.
Using transplants: If you start seeds indoors, do so 3 to 4 weeks before your planting date. Harden off the plants for a week before moving them outside. Plant transplants at the same depth they were in the pot.
Caring For Spring Squash
Spring squash grows fast. You will see fruit in 45 to 60 days for summer types. Winter squash takes 80 to 110 days.
- Watering: Give squash 1 to 2 inches of water per week. Water at the base of the plant to avoid wet leaves, which cause disease.
- Mulching: Add a 2-inch layer of straw or wood chips around the plants. This keeps soil moist and prevents weeds.
- Fertilizing: Apply a balanced fertilizer (10-10-10) when the plants start to vine. Follow the package directions.
- Pest control: Watch for squash bugs and vine borers. Use row covers early in the season. Remove them when flowers appear so bees can pollinate.
Late Summer Planting For A Fall Harvest
Many gardeners do not realize they can plant squash a second time. A late summer planting gives you a fresh crop in the fall. The weather is cooler, and pests are often less active.
Timing Your Fall Planting
Count backward from your first expected fall frost. Summer squash needs about 50 days to mature. Winter squash needs 80 to 110 days.
For example, if your first frost is October 15:
- Plant summer squash by August 25.
- Plant winter squash by July 25.
In south Georgia, you can plant winter squash as late as early August. In north Georgia, aim for mid-July.
Tips For Late Summer Planting
Late summer heat can be tough on young squash plants. Here is how to help them survive.
- Water deeply in the morning. The soil dries out fast in August.
- Provide shade for the first week. Use a shade cloth or plant near taller crops like corn.
- Mulch heavily to keep the roots cool.
- Watch for powdery mildew. This disease is common in humid Georgia summers. Use a fungicide or a milk spray (1 part milk to 9 parts water) as a preventive.
Choosing The Right Squash Varieties For Georgia
Some squash varieties perform better in Georgia’s heat and humidity. Pick disease-resistant types for the best results.
Best Summer Squash Varieties
- Yellow Crookneck: A classic Georgia favorite. It handles heat well.
- Zucchini ‘Black Beauty’: Reliable and productive.
- Pattypan ‘Sunburst’: A fun, scalloped shape. Tolerates humidity.
- Zephyr: A hybrid with good disease resistance.
Best Winter Squash Varieties
- Butternut ‘Waltham’: Very popular in the South. Stores well.
- Acorn ‘Table Queen’: Quick to mature (80 days).
- Spaghetti Squash: Fun to cook. Needs 90 days.
- Pumpkin ‘Howden’: Great for carving or pies. Needs 110 days.
Common Mistakes When Planting Squash In Georgia
Avoid these errors to get a better harvest.
Planting Too Early
The biggest mistake is planting squash before the soil warms up. Cold soil causes seeds to rot. Even if they sprout, the plants will be stunted. Wait until the soil is consistently above 60°F.
Planting Too Late For Fall
Winter squash needs a long growing season. If you plant too late in the summer, the fruit will not mature before the first frost. Check your frost dates and count backward.
Overcrowding Plants
Squash plants need space. Crowded plants get less air flow, which leads to powdery mildew. Follow the spacing guidelines on the seed packet.
Ignoring Pests
Squash bugs and vine borers can kill your plants quickly. Check the undersides of leaves every few days. Remove any eggs or bugs by hand. Use insecticidal soap if needed.
Harvesting Squash At The Right Time
Knowing when to pick your squash improves the flavor and texture.
Summer Squash Harvest
Pick summer squash when they are small and tender. For zucchini, harvest at 6 to 8 inches long. For yellow squash, pick at 4 to 6 inches. Check the plants every day or two. If you leave them too long, they become tough and seedy.
Winter Squash Harvest
Winter squash is ready when the rind is hard and cannot be punctured with your fingernail. The stem will start to dry and crack. Cut the fruit from the vine with a sharp knife, leaving 2 to 3 inches of stem attached.
Cure winter squash in a warm, dry place for 10 to 14 days. This hardens the skin and improves storage life. Store them in a cool, dark spot at 50°F to 55°F.
Frequently Asked Questions About Planting Squash In Georgia

What is the best month to plant winter squash in Georgia?
For most of Georgia, April is the best month for spring-planted winter squash. For fall harvest, July is best. Check your specific region’s frost dates.
How late can I plant squash in Georgia?
You can plant summer squash as late as early September in south Georgia. In north Georgia, stop planting by late August. Winter squash should be planted by early August in most areas.
Do I need to cover squash plants if a frost is forecast?
Yes. Squash is very sensitive to frost. If a light frost is predicted, cover your plants with a sheet or row cover overnight. Remove it in the morning when temperatures rise.
Can I grow squash in containers in Georgia?
Yes, but choose bush varieties like ‘Bush Baby’ zucchini or ‘Table King’ acorn squash. Use a container that is at least 5 gallons in size. Make sure it has drainage holes. Place it in full sun and water daily in hot weather.
Final Tips For Succesful Squash Growing In Georgia
Squash is one of the most rewarding crops for Georgia gardeners. With the right timing, you can enjoy fresh squash from spring through fall.
Here are a few last pointers:
- Keep a garden journal. Write down your planting dates, weather, and harvest times. This helps you plan better next year.
- Rotate your squash patch each year. Do not plant squash in the same spot for at least two years. This reduces soil-borne diseases.
