Garden Tips for January

David Hillock


Lawn and Turf

  • Continue mowing cool-season lawns on a regular basis (HLA-6420)
  • Continue to control broadleaf weeds in well-established warm or cool-season lawns with a post-emergent broadleaf weed killer.

 

Trees and Shrubs

  • Continue controlling over wintering insects on deciduous trees or shrubs with dormant oil sprays applies when the temperature is above 40 degrees in late fall or winter. Do not use dormant oils on evergreens.

 

General

  • Keep all plants watered during dry conditions even though some may be dormant. Especially broadleaf and narrow leaf evergreens and plants under eves or in raised beds and planters.
  • Irrigate all plantings at least 24 hours before hard-freezing weather if soil it dry. (HLA-6404)
  • Till garden plots without a cover crop to further expose garden pests to harsh winter conditions.
  • Now is a great time to design and make structural improvements in your garden or landscape.
  • Send in mail-order catalogs if you are not already on their mailing lists.
