Alabama’s mild winters allow kale to be planted in early spring or late fall for continuous growth. Knowing the best time to plant kale in alabama is key to a succesful harvest. This guide covers everything you need for a thriving kale patch in the Yellowhammer State.
Kale is a cool-season crop that loves Alabama’s moderate temperatures. It actually gets sweeter after a light frost. You can enjoy fresh leaves from your garden for months with proper timing.
Best Time To Plant Kale In Alabama
The ideal window for planting kale in Alabama is late summer for a fall harvest. Aim for August through September. This gives plants time to mature before the first hard freeze.
For a spring crop, plant kale in late February or early March. Soil temperatures should be above 40°F. You can start seeds indoors 4-6 weeks before the last frost date.
Fall Planting Schedule
Fall is the prefered season for kale in Alabama. The cooler weather improves flavor and reduces pest problems.
- North Alabama: Plant from August 15 to September 15
- Central Alabama: Plant from September 1 to October 1
- South Alabama: Plant from September 15 to October 15
Kale takes 50-75 days to mature from seed. Count backwards from your average first frost date. This ensures harvest before winter sets in.
Spring Planting Schedule
Spring planting works well if you time it right. Kale bolts quickly in hot weather. You want it to mature before temperatures hit 80°F.
- Start seeds indoors 4-6 weeks before last frost
- Harden off seedlings for 7-10 days
- Transplant outdoors 2-3 weeks before last frost
- Use row covers if a late freeze is forecasted
Most Alabama gardeners have success with a March 1 to April 1 planting window. Harvest ends by late May or early June.
Understanding Alabama’s Growing Zones
Alabama spans USDA hardiness zones 7a to 9a. This affects your planting calendar. Northern areas have colder winters and shorter growing seasons.
Zone 7A And 7B
These zones cover north Alabama including Huntsville and Birmingham. First frost comes around October 15-25. Last frost is around April 10-20.
Plant fall kale in mid-August. For spring, transplant in late February or early March. Use cold frames to extend your harvest into December.
Zone 8A And 8B
Central Alabama including Montgomery and Tuscaloosa falls here. First frost is November 1-15. Last frost is March 25-April 10.
Fall planting works best from September 1-15. Spring planting can start in early March. You might harvest kale through January with protection.
Zone 9A
South Alabama including Mobile and Gulf Shores has mild winters. First frost is December 1-15. Last frost is February 15-March 1.
Plant fall kale from September 15 to October 15. Spring planting can begin in February. You can grow kale nearly year-round here.
Choosing The Right Kale Varieties
Not all kale grows well in Alabama’s climate. Some varieties handle heat better. Others tolerate cold extremes.
Heat Tolerant Varieties
These work for spring planting or early fall:
- Red Russian – Tolerates heat and cold
- White Russian – Similar to Red Russian
- Lacinato (Dinosaur) – Holds up in warm weather
- Scarlet – Beautiful color and heat resistant
Cold Hardy Varieties
These survive frost and snow:
- Winterbor – Very cold tolerant
- Vates Blue Curled – Hardy to 0°F
- Siberian – Extremely cold resistant
- Premier – Good for winter harvests
Preparing Your Soil For Kale
Kale grows best in rich, well-draining soil. Test your soil pH first. Aim for 6.0 to 7.5 for optimal growth.
Soil Amendments
Add these before planting:
- Compost – 2-3 inches worked into top 6 inches
- Aged manure – 1-2 inches if available
- Nitrogen fertilizer – 1 pound per 100 square feet
- Lime – If pH is below 6.0
Kale is a heavy feeder. It needs plenty of nitrogen for leaf growth. Side-dress with compost tea every 3-4 weeks.
Raised Beds Vs. Ground Planting
Raised beds warm up faster in spring. They also drain better in Alabama’s heavy clay soils. Ground planting works if you amend the soil well.
For raised beds, use a mix of topsoil, compost, and perlite. For ground beds, till in organic matter to a depth of 8-10 inches.
How To Plant Kale Seeds
Direct sowing is easiest for fall planting. Start seeds indoors for spring crops. Follow these steps for success.
Direct Sowing
- Prepare soil to a fine tilth
- Sow seeds 1/4 to 1/2 inch deep
- Space seeds 1 inch apart in rows 18 inches apart
- Water gently to avoid washing seeds away
- Thin seedlings to 12-18 inches apart when 4 inches tall
Keep soil moist during germination. Seeds sprout in 5-10 days at 70°F. In hot weather, shade the bed with row cover.
Starting Indoors
- Use seed starting mix in 2-inch pots
- Sow 2-3 seeds per pot, 1/4 inch deep
- Place under grow lights or in a sunny window
- Keep soil temperature at 65-75°F
- Thin to one seedling per pot after true leaves appear
- Harden off for 7 days before transplanting
Transplant seedlings when they have 4-5 true leaves. Space them 12-18 inches apart in the garden.
Caring For Your Kale Plants
Kale is relatively low-maintenance. Consistent care produces tender, flavorful leaves. Follow these tips for best results.
Watering Requirements
Kale needs 1-2 inches of water per week. Water deeply at the base to avoid leaf diseases. Mulch around plants to retain moisture.
- Water in the morning to reduce evaporation
- Use drip irrigation or soaker hoses
- Increase watering during dry spells
- Reduce watering in cool weather
Fertilizing Schedule
Feed kale every 3-4 weeks during the growing season. Use a balanced fertilizer or compost tea.
- Apply 10-10-10 fertilizer at planting time
- Side-dress with nitrogen-rich fertilizer after 4 weeks
- Use fish emulsion or seaweed spray monthly
- Stop fertilizing 2 weeks before harvest
Pest And Disease Management
Common pests in Alabama include aphids, cabbage worms, and flea beetles. Use row covers to protect young plants.
- Handpick cabbage worms and caterpillars
- Spray neem oil for aphids
- Use diatomaceous earth for flea beetles
- Rotate crops to prevent soil-borne diseases
Diseases like downy mildew and black rot can occur. Space plants for good air circulation. Avoid overhead watering.
Harvesting Kale At The Right Time
You can start harvesting baby kale leaves in 30 days. Full-sized leaves take 50-75 days. Pick leaves from the bottom up.
Harvesting Tips
- Harvest outer leaves first, leaving the center to grow
- Pick leaves when they are 6-8 inches long
- Cut stems 1-2 inches from the base
- Harvest in the morning for best flavor
- Stop harvesting if plants start to bolt
Kale tastes sweeter after a frost. In Alabama, fall-harvested kale is usually the most flavorful. Spring kale can be more bitter.
Extending The Harvest
You can harvest kale well into winter with protection. Use these methods:
- Cold frames – Extend harvest by 4-6 weeks
- Row covers – Protect down to 20°F
- Mulch heavily – Insulates roots from cold
- Harvest before hard freezes – Leaves freeze and thaw poorly
Common Mistakes To Avoid
Many gardeners make these errors with kale. Avoid them for a better harvest.
Planting Too Late In Spring
Kale bolts when temperatures exceed 80°F. Plant early enough so it matures before summer heat. In Alabama, this means March planting at the latest.
Overcrowding Plants
Kale needs 12-18 inches between plants. Crowded plants produce smaller leaves and are more prone to disease. Thin seedlings ruthlessly.
Ignoring Soil Quality
Kale is a heavy feeder. Poor soil leads to stunted growth and bitter leaves. Always amend with compost and fertilizer before planting.
Not Using Row Covers
Flea beetles and cabbage worms can destroy young kale. Row covers are cheap insurance. Remove them when plants are established.
Kale Companion Planting
Certain plants help kale grow better. Others attract pests. Plan your garden layout carefully.
Good Companions
- Beets – Share similar soil needs
- Carrots – Don’t compete for space
- Onions – Repel pests
- Mint – Deters cabbage moths
- Nasturtiums – Trap aphids
Bad Companions
- Strawberries – Compete for nutrients
- Tomatoes – Attract similar pests
- Peppers – Same disease issues
- Potatoes – Compete for space
Seasonal Care Tips
Adjust your care based on the season. Alabama’s weather varies greatly throughout the year.
Spring Care
- Watch for late frosts – Cover plants if needed
- Water regularly as temperatures rise
- Harvest frequently to encourage growth
- Remove bolting plants immediately
Summer Care
- Kale usually stops growing in summer heat
- Keep plants mulched and watered
- Consider shade cloth for partial shade
- Focus on fall planting preparation
Fall Care
- Plant in late summer for best results
- Water consistently during dry spells
- Apply a nitrogen boost after 4 weeks
- Protect from early frosts with row covers
Winter Care
- Kale can survive Alabama winters with protection
- Harvest leaves before hard freezes
- Use cold frames or heavy mulch
- Plants may go dormant in January
