After decidious trees have lost their leaves, mistletoe is easy to spot. To control, remove the branch at its point of origin and at least one foot below the mistletoe cluster. (Photo: UC IPM)

Tasks
  • Remove fallen camellia blossoms promptly to prevent petal blight on next year's flowers
  • Mistletoe is very difficult to control because reinfestation occurs from nearby infected trees. An infected branch must be removed at its points of origin and at least one foot below the cluster.

Pruning

  • Wait to prune spring?flowering plants until after bloom - deciduous magnolias, spiraea, azaleas, and camellias
  • Do not apply any treatments to pruning cuts or other wounds, because these materials are ineffective and often detrimental to plant health

Fertilizing

  • No fertilization is recommended this month

Planting

  • Bare root plants started now, while they are dormant, will have the full advantage of the spring growing season and will be well established during the coming year
  • Bulbs, corms, tubers: cyclamen, dahlia
  • Fruits and vegetables: bare root cane berries, garlic, leek

Enjoy now

  • Annuals and perennials: dianthus, poinsettia (Euphorbia pulcherrima), toadflax (Linaria maroccana), stock (Matthiola)
  • Bulbs, corms, tubers: snowdrop (Galanthus), narcissus
  • Trees, shrubs, vines: camellia, Hawthorne (Crataegus)
  • Fruits and vegetables: avocado, grapefruit, kumquat, pomegranate

Things to ponder

  • Look through garden books for landscaping ideas using drought-tolerant or water-wise plants
  • Avoid overhead watering if frost is expected
