Collard greens are one of Georgia's classic cool-season vegetables. They can produce in both spring and fall, but fall is especially valuable: plants establish as summer fades, mature in cooler weather and can keep a Georgia garden productive long after many warm-season vegetables are finished.
Collards are deeply at home in Georgia gardens and Southern kitchens. University of Georgia Extension describes collards as a popular Georgia crop, and the state's relatively mild winters create opportunities to keep cool-season greens producing into colder months. Unlike okra and watermelon, which define the heat of a Georgia summer, collards help extend the garden into fall and winter.
The plant is closely related to cabbage, kale and broccoli, but collards form large open leaves rather than a tight head. That growth habit makes them particularly useful for a cut-and-come-again harvest: remove mature outer leaves while leaving the center growing point intact so the plant can continue producing.
Georgia Collard Quick Facts
Collards are a cool-season vegetable well suited to Georgia spring and fall gardens.
UGA's statewide planting chart lists Blue Max, Georgia Southern and Hevi-Crop among recommended cultivars.
A general statewide guide lists spring planting around February 1–March 15 and fall planting around August 1–September 1, with regional adjustments needed.
Fall and winter gardens can face fewer insect pests, lower disease pressure and lower irrigation demand than summer gardens.
Outer leaves can be harvested while the center remains growing for repeated harvests.
When to Plant Collard Greens in Georgia
Georgia's geography matters. UGA's statewide chart gives useful middle-of-the-state planning dates, but Extension notes that spring planting can run earlier in South Georgia and later in North Georgia, while fall timing shifts in the opposite direction.
Spring: A statewide guide uses approximately February 1 through March 15. Adjust for local conditions and your part of Georgia.
Fall: Approximately August 1 through September 1 is a useful statewide starting point. Fall collards should establish while soil is still warm enough for growth and then mature as temperatures moderate.
Winter harvest: Established collards can continue producing into cold weather in much of Georgia, with local temperatures and protection determining how long harvest lasts.
Best Collard Varieties for Georgia Gardens
For this page, we're prioritizing cultivars that appear in UGA's Georgia vegetable recommendations rather than treating every nationally sold collard as equally proven for the state.
Georgia Southern: The name alone reflects its long association with Southern gardens, and UGA includes it among Georgia recommendations.
Blue Max: Another UGA-listed option for Georgia home gardens.
Hevi-Crop: Included with Blue Max and Georgia Southern in UGA's statewide planting chart.
How to Grow Collard Greens in Georgia
Choose a sunny, well-drained site: Good light supports strong leaf production, while well-drained soil helps prevent root problems.
Start with a soil test: Use Georgia soil-test recommendations to guide lime and fertilizer rather than guessing.
Give plants adequate room: UGA's statewide chart uses rows about 36 inches apart with roughly 8–16 inches between plants as a general guide.
Keep young plants watered: This is particularly important for a fall crop started while late-summer Georgia weather is still hot and dry.
Mulch: Mulch helps moderate soil moisture, suppress weeds and protect the soil around established plants.
Watch the growing point: When harvesting leaves, avoid damaging the center of the plant if you want continued production.
Why Fall Is Such a Good Collard Season
A Georgia fall garden takes advantage of conditions that become progressively friendlier to cool-season crops. UGA notes that winter gardening can mean fewer insect pests, less disease pressure and reduced irrigation needs. Some cool-season vegetables may also develop improved flavor following frost.
The important part is starting early enough. A winter garden often begins while it still feels like summer: collards are commonly started during August and September so plants can establish before consistently cold weather arrives.
How to Harvest Collard Greens for a Longer Season
Collards do not need to be harvested all at once. Once leaves reach usable size, begin with the larger outer leaves and work inward while preserving the center growing point.
Harvest healthy outer leaves at the size and tenderness you prefer.
Leave younger center leaves and the growing point intact.
Remove yellowed or badly damaged leaves rather than leaving them around the plant.
Continue checking plants through cool weather; growth slows as temperatures fall but established plants can remain productive.
Collard Greens in Georgia and Southern Cooking
Growing collards is only half their value. In Southern cooking they can be slowly simmered with smoked meat, onions and seasoning, quickly sautéed, added to soups and stews, or used anywhere a sturdy leafy green is needed. Their ability to move directly from a cool-season Georgia garden to a traditional Southern meal gives this crop a particularly strong place on GA Garden.
From Georgia Collards to the Southern Table
These two preparations show both sides of collards: the long, slow Southern pot and a faster fresh sauté.

Georgia Collard Growing Calendar
Use this as a seasonal framework rather than a single statewide rule. Georgia planting dates shift with latitude, elevation, frost timing and year-to-year weather.
Spring Planting (March - May)
March: Start planting collard greens seeds or seedlings in early spring when the soil is workable. Collard greens prefer well-drained soil with a slightly acidic to neutral pH. Choose a sunny location for planting, as collards can tolerate some cooler temperatures.
April: Continue planting collard greens throughout April, spacing the seeds or seedlings according to the recommendations on the packet. Keep the soil consistently moist for germination and early growth.
May: Harvest collard green leaves as they reach the desired size. Collards are also a cut-and-come-again crop, so you can continue harvesting outer leaves while allowing the inner leaves to grow.
Summer Considerations (June - August)
June: Collard greens are relatively heat-tolerant, but they can still be adversely affected by the intense heat of summer. In June, you may continue to harvest collard greens from the spring planting. However, as temperatures rise, the leaves may become more bitter. Consider harvesting the remaining spring-planted collards and use the space for warm-season crops.
July: Collards can endure some heat, but their flavor may be compromised in the summer months. If you didn't already do so, clear away any debris from the spring planting and consider planting other vegetables that thrive in the warm season.
August: Use August to plan for a fall collard greens crop. Prepare the soil by adding compost or organic matter, and plan your garden layout for the upcoming season.
Fall Planting (September - November)
September: Late summer to early fall is an excellent time to start your fall collard greens crop. Plant seeds or seedlings directly into the soil, and ensure the soil is consistently moist for successful germination.
October: Continue planting collard greens as needed. The cooler temperatures of fall are ideal for collards, and the leaves will be sweet and tender. Keep an eye on pests and diseases, and address them promptly.
November: Harvest fall-planted collard greens as they mature. Collards are known for their cold tolerance, and you may be able to continue harvesting even as temperatures start to drop.
It's important to note that specific varieties of collard greens may have different temperature tolerances, so it's a good idea to choose varieties that are well-suited to the conditions in your region of Georgia. Additionally, practicing succession planting can help you maintain a continuous supply of fresh collard greens throughout the growing season. Adjust the planting schedule based on local climate conditions and the specific needs of the collard greens varieties you choose.
Common Collard Pests in Georgia
Collard greens, like other cruciferous vegetables, can be affected by various pests that may impact their growth and quality. Here are some common pests for collard greens, along with descriptions, the damage they cause, and control measures:
Aphids (Various species)
Description: Small, soft-bodied insects that come in various colors.
Damage: Aphids suck sap from collard green leaves, causing distortion, yellowing, and the secretion of honeydew that can attract sooty mold.
Control: Conserve beneficial insects and monitor aphids. On small plantings, a strong stream of water can reduce populations; use a product labeled for collards and aphids only when treatment is warranted.
Cabbage Worms (Pieris rapae)
Description: Green caterpillars with a velvety appearance.
Damage: Caterpillars feed on collard green leaves, creating irregular holes and causing damage to the outer leaves.
Control: Handpick caterpillars when practical and use row covers before pest entry. Bt products can work on susceptible young caterpillars when labeled for the crop and pest; follow label directions.
Diamondback Moth (Plutella xylostella)
Description: Small, grayish-brown moths with a diamond-shaped pattern on their wings.
Damage: Larvae feed on the undersides of collard green leaves, creating small holes and causing a lacy appearance.
Control: Use row covers where practical, conserve natural enemies and monitor feeding. Use labeled controls only when damage warrants treatment.
Flea Beetles (Phyllotreta spp.)
Description: Small, jumping beetles, often black or brown in color.
Damage: Flea beetles feed on collard green leaves, creating small holes and causing a stippled appearance. Severe infestations can lead to reduced plant growth.
Control: Protect young plants with row covers where practical and monitor feeding injury. Use a product labeled for collards and flea beetles only when treatment is justified.
Slugs and Snails
Description: Soft-bodied, slimy mollusks.
Damage: Feed on collard green leaves, causing irregular holes and damage.
Control: Reduce moist hiding places and handpick slugs or snails when practical. Use a labeled slug or snail control if damage becomes significant.
Whiteflies (Various species)
Description: Tiny, white insects that fly away when disturbed.
Damage: Whiteflies feed on collard green sap, causing yellowing, wilting, and the development of sooty mold.
Control: Monitor whiteflies and conserve natural enemies. Reflective mulch can help reduce some early pressure; use labeled controls only when populations warrant treatment.
Integrated pest management (IPM) practices, including regular monitoring, early detection, and a combination of cultural, biological, and chemical controls, can help manage pest problems in collard greens effectively. Always follow recommended guidelines for the specific pest control methods you choose.
Georgia Companion Planting with Collard Greens
Collards can share cool-season beds with onions, garlic, beets, lettuce and herbs when spacing allows. Flowers around bed edges can support beneficial insects, but leave enough airflow around the large leaves.
Rotation is especially important because collards are brassicas. Cabbage, kale, broccoli, cauliflower, Brussels sprouts and mustard relatives can share pests and diseases. Moving from collards directly into another brassica in the same bed is not much of a rotation.
Collards as a Georgia and Southern Food Tradition
Collards connect the garden directly to Southern food culture. Their ability to produce during cool weather also gives them practical importance in Georgia: they extend the edible garden beyond the tomato-and-okra summer season and into fall and winter.
