01 January guide

Start the Year with a Garden Plan

January is for dreaming and doing the groundwork. While the garden sleeps, smart planning sets you up for a productive season ahead.

What January means

January offers gardeners a critical window for planning. With most of the garden dormant, it is the perfect time to review the past season, order seeds, and sketch layout changes. Bare-root trees and shrubs can be planted when the ground is workable. Indoor seed starting for slow-growing crops like onions, leeks, and certain perennials gives transplants a head start. Pruning dormant deciduous trees and fruit trees is easier now, with no foliage obscuring structure. Soil testing kits sent to a lab in January return results well before spring planting deadlines, giving you time to amend properly.

January tasks

08
  • 01 Order seeds and bare-root plants from catalogs before popular varieties sell out
  • 02 Start onion, leek, and celery seeds indoors under grow lights — they need a long growing season
  • 03 Prune dormant deciduous fruit trees (apple, pear, plum) while branch structure is visible
  • 04 Send soil samples to your local extension office for pH and nutrient analysis
  • 05 Clean, sharpen, and oil garden tools to prevent rust and ensure clean cuts in spring
  • 06 Check stored dahlia tubers, canna rhizomes, and gladiolus corms for rot and desiccation
  • 07 Sketch your garden layout on paper, rotating crop families from last year to reduce disease
  • 08 Spread winter mulch over exposed perennial beds if snow cover is lacking

Plants to start in January

07
  • Onions (from seed indoors)
  • Leeks (from seed indoors)
  • Celery (from seed indoors)
  • Pansies (from seed indoors for early spring transplant)
  • Snapdragons (from seed indoors)
  • Hellebores (plant bare-root if ground is workable)
  • Fruit trees (bare-root planting when soil is not frozen)

Design tips for January

04
  • 01 Use the dormant garden as a canvas — photograph beds from upstairs windows to evaluate proportions and flow before making changes
  • 02 Plan focal points for each season so the garden has interest year-round, not just in summer
  • 03 Sketch paths and hardscape changes on graph paper now while installation is still months away
  • 04 Identify areas where winter structure (evergreens, bark, berries) is lacking and earmark those spots for improvement

FAQ

Frequently Asked Questions

01 What should I plant in January?

In most temperate climates, January planting is limited to bare-root trees and shrubs when the ground is workable, and indoor seed starting for slow-growing crops like onions, leeks, celery, and certain perennials. In mild-winter zones (USDA 8–10), you can also direct-sow cool-season crops like peas, spinach, and radishes.

02 Is January too early to start planning a garden?

January is the ideal time to plan. Seed catalogs are freshly released, popular varieties sell out by February, and soil test results take 2–4 weeks. Starting now means you will have amendments in hand, seeds organized, and layouts finalized well before spring arrives.

03 How do I protect my garden from frost in January?

Maintain 3–4 inches of mulch over perennial crowns and root zones. Use burlap windbreaks around newly planted evergreens. For any early-started seedlings in cold frames, close lids overnight and ventilate on sunny days above 40°F to prevent overheating.
