Gardening enthusiasts often associate the start of a garden season with the arrival of spring. However, many experienced gardeners know that January is actually one of the best times to begin growing a thriving garden. By starting seeds indoors early, you give plants more time to develop strong roots and grow vigorously when the weather turns warm. This gives you a significant head start and ensures a quicker, more bountiful harvest when the growing season truly begins.
In this article, we’ll explore 10 seeds you should consider starting in January to set yourself up for gardening success. Whether you’re a beginner or an experienced green thumb, these seeds are perfect for early sowing. Let’s dive in and learn about these excellent choices for your January planting!
1. Tomatoes
Tomatoes are a staple in most gardens, and they thrive when started early indoors. Starting tomato seeds in January allows them to get a good head start before being transplanted outside in the spring. Since tomatoes are sensitive to frost, it’s important to start them indoors where they can grow in a warm, controlled environment. After 6-8 weeks, your tomato plants will be ready for the outdoors when the danger of frost has passed.
- Best Varieties to Start in January: Heirloom tomatoes like Brandywine or Cherry tomatoes are ideal for this early start.
- Growing Tip: Keep the indoor environment warm (70-80°F) and provide plenty of light, either from a sunny window or a grow light.
2. Peppers
Much like tomatoes, peppers need a long growing season to develop fully. Starting them in January ensures that you’ll have strong, established plants ready to be transferred to your garden by the time the weather warms up. Peppers require warmth and a steady amount of light to germinate and grow well.
- Best Varieties to Start in January: Bell peppers, Jalapenos, and Hot peppers.
- Growing Tip: Use a heat mat for faster germination and make sure your plants get 12-16 hours of light per day.
3. Herbs: Basil, Parsley, and Oregano
Herbs are a must-have for any garden and can add fresh flavors to your meals all year long. Many herbs, like basil, parsley, and oregano, can be started indoors in January. These plants generally take a little time to grow, so starting early ensures that you can transplant them outdoors when it’s warm enough.
- Best Varieties to Start in January: Basil, Oregano, Parsley, and Thyme.
- Growing Tip: Herbs thrive on a sunny windowsill, but if that’s not possible, a grow light is an excellent alternative.
4. Cabbage and Kale
Cold-hardy vegetables like cabbage and kale can be started indoors in January, allowing them to be ready for early spring planting. These vegetables are known for their ability to withstand frost, so starting them early can lead to a long growing season with multiple harvests. They can be grown indoors until they are sturdy enough to be moved outdoors when the weather improves.
- Best Varieties to Start in January: Winter kale varieties like ‘Winterbor’ and cabbage types like ‘Savoy’ are ideal for an early start.
- Growing Tip: Ensure that your indoor plants are getting enough light to avoid leggy growth. A good grow light will work wonders.
5. Lettuce and Salad Greens
Lettuce and other salad greens are great for an early start in January. These crops grow relatively quickly, and starting them early indoors gives you a fresh supply of greens as soon as the weather warms up. Leaf lettuce, spinach, and arugula are especially suitable for early indoor sowing and can be harvested within a few months.
- Best Varieties to Start in January: Romaine, Butterhead, and Arugula.
- Growing Tip: Keep your indoor environment cool but not freezing, around 55-60°F, and make sure your greens get plenty of light.
6. Onions
Starting onions from seed in January is an excellent way to ensure you get a bountiful harvest come summer. These versatile vegetables need a long growing season to form large, healthy bulbs. Starting indoors in January means that you’ll have the opportunity to transplant them outdoors in early spring, giving them a head start.
- Best Varieties to Start in January: Yellow onions and red onions are popular choices.
- Growing Tip: Ensure that you’re providing plenty of light to your onion seedlings to keep them strong.
7. Celery
Celery is another vegetable that benefits from an early start. It has a long growing season and needs plenty of time to establish its root system before it’s ready to be transplanted outside. Starting celery in January ensures that it will be big and healthy enough to thrive when it’s time to move it outdoors.
- Best Varieties to Start in January: ‘Utah’ celery and ‘Golden Self-Blanching’ celery.
- Growing Tip: Keep celery seedlings in a cool environment (around 60°F) and provide them with at least 12-16 hours of light each day.
8. Cauliflower and Broccoli
Cauliflower and broccoli are part of the cool-season crops that do well when started early. If you want to harvest these nutritious vegetables in the early spring, start seeds in January. Broccoli and cauliflower can withstand some frost, but they do best when they’ve had a few months of indoor growth to establish themselves.
- Best Varieties to Start in January: ‘Calabrese’ broccoli and ‘Snowball’ cauliflower.
- Growing Tip: Keep the plants cool but not cold, and ensure that your seedlings are strong and robust before moving them outdoors.
9. Flowers: Marigolds and Zinnias
Starting flowers early allows you to have a vibrant garden right from the start of the growing season. Marigolds and zinnias are perfect flowers to start in January. These flowers grow quickly and are easy to care for. They also attract pollinators to your garden and help protect other plants.
- Best Varieties to Start in January: ‘African Marigolds’ and ‘Cactus Zinnias.’
- Growing Tip: Keep the temperature consistent and provide plenty of light. Marigolds and zinnias are both sun-loving plants, so a sunny spot is key.
10. Brussels Sprouts
Brussels sprouts are another vegetable that benefits from an early start in January. These cold-tolerant plants need a long growing season to form their small, tightly packed heads, and starting them indoors allows them to mature early in the season. By the time the weather warms up, they’ll be ready to move outside and continue growing.
- Best Varieties to Start in January: ‘Long Island’ and ‘Jade Cross’ Brussels sprouts are ideal for early starts.
- Growing Tip: Make sure to give Brussels sprouts plenty of space to grow and avoid overcrowding, as they need room to produce their sprouts.
Tips for Starting Seeds Indoors in January:
- Temperature Control: Ensure the indoor temperature is warm enough for germination. Most seeds thrive in temperatures between 65-75°F (18-24°C).
- Light: Since days are shorter in winter, invest in grow lights to ensure that your plants get at least 12-16 hours of light daily.
- Humidity: To encourage germination, consider using a humidity dome or a plastic cover to maintain moisture around your seedlings.
- Watering: Be careful not to overwater your seedlings. Use a gentle watering method to avoid disturbing the seeds.
