What to Start in January and February

January and February are the perfect months to kickstart your gardening journey by starting seeds indoors, especially for gardeners in Louisiana. These colder months provide the ideal time to begin growing a variety of plants that will thrive in the warmer spring and summer months.

Knowing which seeds to start, how to care for your seedlings, and how to prepare your soil are crucial steps in setting yourself up for a successful growing season. Here's a list of popular vegetables and herbs to start indoors in January and February:

Tomatoes – Start tomato seeds indoors in late January or early February. Tomatoes need a long growing season, so giving them a head start indoors will ensure they mature before the heat of summer.
Peppers – Like tomatoes, peppers require a longer growing season. Start pepper seeds indoors in late January or early February.
Eggplant – Start eggplant seeds indoors in early February, as they also need a long growing season.
Herbs – Herbs like basil, oregano, thyme, and parsley can be started indoors in late January to February. Fresh herbs will thrive in the spring and summer months.
Cabbage and Kale – These cool-season crops can be started indoors in January and February for a spring harvest.
Lettuce – You can also start lettuce seeds indoors around mid-February to get a jump on the season.
Brussels Sprouts – If you're interested in growing Brussels sprouts, start them indoors in February for a late summer harvest.

When to Start Seeds Indoors

In Louisiana, timing is key for successful seed starting. The last frost date in most of the state is typically around mid-March to early April, so you'll want to time your indoor seed-starting schedule accordingly.

January – Start slow-growing crops such as tomatoes, peppers, and eggplant in late January.
February – Begin starting herbs, cabbage, kale, and lettuce seeds in early to mid-February.

As a rule of thumb, give your seedlings at least 6-8 weeks of indoor growth before transplanting them outdoors. To help with this timing, check your area's average last frost date and plan to plant outdoors once the danger of frost has passed.

How to Care for Your Seedlings

Caring for your seedlings indoors is critical to their success. Here are some key steps to help them thrive:

Light – Most seedlings need at least 12-16 hours of light per day. If you don't have enough natural sunlight, consider using grow lights to provide the necessary light for healthy growth.
Watering – Keep the soil consistently moist but not waterlogged. Use a gentle watering can or spray bottle to avoid disturbing the tiny seeds. Ensure good drainage to prevent root rot.
Temperature – Seedlings generally prefer temperatures between 65-75°F. Keep them in a warm area of your home, away from drafts or direct heat sources.
Air Circulation – Good airflow is crucial for preventing mold and mildew growth. If possible, use a small fan to circulate the air around your seedlings.
Thinning – As seedlings grow, thin them out to prevent overcrowding. This encourages stronger, healthier plants by giving each one more space to grow.

When to Plant Seedlings Outdoors

Timing is everything when it comes to moving your seedlings outdoors. Planting too early in Louisiana's climate could expose your young plants to frost, while waiting too long might stunt their growth as the temperatures rise. Each crop has its own ideal planting window, and using tools like The Old Farmer's Almanac can provide invaluable guidance for determining the best planting dates for your specific location.

General Guidelines for Transplanting Outdoors

Tomatoes, Peppers, and Eggplant: These heat-loving crops should be started indoors 6-8 weeks before the last frost and transplanted outdoors once all danger of frost has passed. For most parts of Louisiana, this typically falls between mid to late March. Use the Old Farmer’s Almanac's planting calendar to pinpoint the exact last frost date for your area and plan accordingly.
Herbs: Delicate herbs like basil and parsley are also sensitive to frost. Start these indoors and transplant them after the last frost, usually around mid to late March. Hardy herbs like thyme and oregano may tolerate cooler conditions and can be planted out earlier.
Cabbage, Kale, and Lettuce: These cool-season crops can handle lower temperatures and can be hardened off and planted outdoors around mid to late February to early March, depending on the weather in your area. Keep an eye on late-winter frosts and cover young plants if necessary.

Using the Old Farmer’s Almanac

The Farmer’s Almanac is an excellent resource for understanding your region’s specific climate and planting needs. By entering your ZIP code or city, you can access a detailed planting calendar that includes:

The average last frost date for your location.
Suggested dates for starting seeds indoors.
Optimal transplanting dates for each crop.

The Almanac also provides insights into moon phases, which some gardeners use to time their planting for optimal growth, and other regional tips for soil preparation and care.

Hardening Off Your Seedlings

Before planting your seedlings outdoors, it’s essential to harden them off. This process helps them transition from the controlled indoor environment to the unpredictable outdoor climate. Here’s how to do it:

Start Gradually: Begin about a week before transplanting. Place your seedlings outdoors in a sheltered area for a few hours each day. Start with 2-3 hours of indirect sunlight.
Increase Exposure: Gradually increase the time spent outdoors and the amount of direct sunlight they receive. By the end of the week, they should be able to handle full sun and outdoor temperatures.
Watch the Weather: Avoid exposing seedlings to heavy rain, strong winds, or temperatures below 50°F during the hardening-off period. Bring them indoors if the weather turns harsh.

Preparing the Soil for Transplanting

Once your seedlings are hardened off and ready to move outdoors, ensure your garden is prepared:

Test and Amend the Soil: Use a soil test kit to check pH and nutrient levels. Most vegetables prefer slightly acidic to neutral soil (pH 6.0-7.0). Amend the soil with compost or organic matter to improve fertility and drainage.
Warm the Soil: For warm-season crops like tomatoes and peppers, consider using black plastic mulch to warm the soil earlier in the season.
Space and Watering: Follow the recommended spacing for each crop and water thoroughly after transplanting to help seedlings settle into their new environment.

By carefully timing your indoor seed starting and outdoor transplanting, using tools like the Farmer’s Almanac, and properly hardening off your plants, you’ll set your spring garden up for success. A little preparation now ensures a thriving, productive garden later!

Conclusion

Starting seeds indoors in January and February gives you a head start on the growing season and ensures that you’ll have a strong, healthy garden when spring arrives. By choosing the right crops, timing your planting correctly, and preparing your garden beds, you can enjoy a successful gardening season in Louisiana.
