Many seeds can be started indoors or outdoors, depending on your space and climate. Here’s a detailed guide to 9 seeds you can start right now, along with tips on how to grow them successfully.
1. Tomatoes
Tomatoes are a staple in many gardens because they are versatile, productive, and relatively easy to grow.

- Provide 12–16 hours of light per day with natural sunlight or grow lights.
Outdoor Planting:
- Transplant seedlings outdoors after the risk of frost has passed.
- Choose full sun locations with well-draining soil.
- Space plants 18–24 inches apart to allow airflow and reduce disease.
Tips: Tomatoes thrive when watered consistently and fertilized regularly with a balanced, nutrient-rich fertilizer. Varieties like cherry tomatoes or Roma are beginner-friendly and highly productive.
2. Lettuce
Lettuce is fast-growing, easy to handle, and perfect for small spaces or containers.

- Keep the soil moist but not waterlogged.
Outdoor Planting:
- Sow seeds directly into garden beds as soon as the soil can be worked.
