Things to Plant in January 🌱
What You Can Grow Even in the Coldest Month
January may seem like a quiet time in the garden, but it’s actually one of the most important months for planning and planting—especially if you know what to grow and where. While outdoor conditions vary by climate, many vegetables, herbs, and flowers can be started indoors, under cover, or directly in mild regions.
Planting in January gives crops a strong head start and leads to earlier, healthier harvests.
🌍 Know Your Climate First
Before planting in January, consider:
- Your USDA hardiness zone or local climate
- Whether you’re planting indoors, in a greenhouse, or outdoors
- Frost risk and daylight hours
This article covers options for cold, moderate, and mild winter climates.
