Garden Tips for November

David Hillock

 

Lawn and Turf

  • Fertilize cool-season grasses like fescue with 1 pound nitrogen per 1000 sq. ft.
  • Continue to mow fescue as needed at 2 inches and water during dry conditions.
  • Control broadleaf winter weeds like dandelions (HLA-6601).
  • Keep falling leaves off fescue to avoid damage to the foliage.

 

Tree and Shrub

  • Prune deciduous trees in early part of winter.  Prune only for structural and safety purposes.
  • Wrap young, thin-barked trees with a commercial protective material to prevent winter sunscald.
  • Apply dormant oil for scale infested trees and shrubs before temperatures fall below 40 degrees Fahrenheit.  Follow label directions.
  • Continue to plant balled and burlapped and containerized trees.
  • Watch for arborvitae aphids, which tolerate cooler temperatures in evergreen shrubs.

 

Flowers

  • Tulips can still be successfully planted through the middle of November.
  • Leave foliage on asparagus, mums, and other perennials to help insulate crowns from harsh winter conditions.
  • Bulbs like hyacinth, narcissus and tulip can be potted in containers for indoor forcing.

 

Miscellaneous

  • Leftover garden seeds can be stored in an airtight container in the refrigerator or freezer until next planting season.  Discard seeds over 3 years old.
  • Gather and shred leaves.  Add to compost, use as mulch or till into garden plots.
  • Clean and store garden and landscape tools.  Coat with a light application of oil to prevent rusting.  Drain fuel tanks, irrigation lines, and hoses.  Bring hoses indoors.

 

Fruits and Nuts

  • Delay pruning fruit trees until next February or March before bud break.
  • Harvest pecans and walnuts immediately to eliminate deterioration of the kernel.
