Begin planning your garden. Research heirloom varieties suited to your region. Start seeds for cool-season crops like lettuce, kale, and broccoli if you have a mild winter.

Start seeds for early crops such as tomatoes, peppers, and eggplants. Use seed trays or pots with quality soil. Maintain consistent warmth and moisture.
