Gardening is a rewarding pursuit that connects us with nature and provides fresh produce, vibrant flowers, and a sense of accomplishment. However, knowing what to plant and when can make all the difference in a thriving garden. This month-by-month gardening calendar is tailored for temperate climates (USDA Hardiness Zones 5–8), with adjustments for other regions where applicable. Whether you’re growing vegetables, herbs, or flowers, this guide offers a comprehensive plan to keep your garden flourishing year-round.
January: Planning and Indoor Prep
Overview: January is a quiet month for outdoor gardening in colder climates, but it’s the perfect time for planning and starting seeds indoors. In warmer regions (Zones 9–11), you can begin cool-season crops outside.
What to Plant
Indoors (All Zones): Start seeds for slow-growing crops like tomatoes, peppers, eggplants, and leeks. Use seed trays with a quality seed-starting mix and keep them under grow lights or in a sunny window.
Cool-Season Crops (Zones 9–11): Plant lettuce, spinach, kale, radishes, and peas directly in the ground. These thrive in cooler temperatures.
Flowers: Begin pansies, snapdragons, and petunias indoors for spring transplanting.
Tasks
Order seeds from reputable suppliers and plan your garden layout.
Clean and sterilize pots and tools to prevent disease.
Check stored bulbs (e.g., dahlias, gladiolus) for rot or pests.
Tip: Use a gardening journal to map out crop rotations and avoid soil depletion.
February: Early Spring Prep
Overview: February signals the start of the gardening season. Indoor seed starting ramps up, and in milder climates, you can begin outdoor planting.
What to Plant
Indoors (Zones 5–8): Sow seeds for broccoli, cauliflower, cabbage, and Brussels sprouts. These brassicas need a head start for spring planting.
Outdoors (Zones 9–11): Direct-sow carrots, beets, Swiss chard, and turnips. Plant onion sets or transplants.
Flowers: Start seeds for marigolds, zinnias, and cosmos indoors.
Tasks
Prune fruit trees and dormant shrubs to encourage healthy growth.
