Garden Checklist for the week of Jan.15, 2020

Nurseries will begin to have plants in bloom now so you can find the colors you really want before you plant them.


    • Rainfall may not reach areas under eaves and overhangs.  Check soil moisture and apply supplemental water if needed.

    • Apply preemergent herbicide to lawns and beds in the late part of the month to control crabgrass and other early germinating weeds.


    • Finish pruning roses and deciduous fruit trees by the end of the month.

    • At bud swell, spray deciduous fruit, almond trees and roses with dormant oil to prevent and control for over-wintering insects.

    • Prune out fire blight infections. Remove the infected shoot or branch at its point of origin.


    • Fertilize spring-flowering perennials, annuals, bulbs and shrubs.

     • Yellow foliage, particularly the youngest leaves, may be attributed to iron deficiency. Yellowing in older leaves may be attributed to nitrogen deficiency.


    • Group plants with similar water needs together.

    • This is a good time to move perennials, shrubs or small trees.

    • Spring planting season begins next month. Work on your garden plans and be ready to start next month.

Consult the California Garden Web for more information.

Enjoy Now!

     • Annuals and perennials: feverfew (Chrysanthemum parthenium), toadflax (Linaria maroccana), cyclamen.

    • Citrus fruits are abundant now. Use to brighten up the winter menu.

Things to ponder

frost damage
  • Leave frost-damaged growth on tender plants as protection until the danger of frost is past. Begin pruning as new growth emerges.
