Gardening Tips for January for Longview, WA

Northwest Region

  • Order seed catalogs. See our Mail Order List for ideas.
  • Begin planning this year’s garden. Consider companion planting—some plants grow better when planted near each other! Add plants that attract beneficial insects (such as sunflower, yarrow, dill, and coriander).
  • Before the spring, test your garden soil for its pH levels. Contract your local Cooperative Extension office for a soil kit.
  • Check your storage areas and get rid of old and unwanted pesticides. Visit for information on safe disposal.
  • Plant hardy, pest- and disease-resistant plants, especially if certain varieties have been troublesome in the past. For example, consider deer-resistant plants!
  • Prune trees and shrubs while they’re dormant. For trees and shrubs that bloom in summer, prune on the current year’s growth in winter. Note: For those that bloom in spring from buds on 1-year-old wood, prune just after flowers fade.
  • If your mulch was blown or washed away, reapply it around your plants.
  • Prevent lawn damage by limiting the traffic on your frozen lawn.
  • When temperatures are above freezing, water your plants deeply to prevent them from drying out.
  • Remove the snow from your shrubs to prevent them from breaking.
  • Remove leaves and other debris from your yard and around your plants (if there is not too much snow) to help reduce pests and diseases.
  • Check your houseplants: Look for any insects or diseases.
