July in the Garden

  • You can still plant seeds of annuals: zinnias, marigolds, sunflowers and alyssum will grow and bloom this year.
  • Be sure everything is well mulched for the heat of summer. Water before 10 am to avoid fungal infections and to minimize water loss to evaporation.
  • If you have blackberries in your garden, cut the canes that bore fruit to the ground. Tie up 3-5 of the new canes and fertilize to promote new growth.
  • Cut canna stems to the ground as they finish flowering to encourage new stems to grow.
  • Dig and divide bearded iris that have not been divided for 3 yrs. Cut the foliage on the divisions to 6-8 inches, replanting only new rhizomes and discarding the old rhizomes.
  • You can dig and divide other bulbs after the foliage has died off.
  • Deadhead blooming plants as they finish flowering to promote continuing bloom. Fertilize roses after each burst of blooms.
  • Cut back lavender after flowering to promote a second bloom. You can prune by half to keep the plant in bounds.
  • If you have fruit trees, be sure to pick up dropped fruit to prevent brown rot from developing and leaving spores for future infection.

UC Master Gardeners of Colusa County

The University of California Master Gardener Program provides the public with UC research-based information about home horticulture, sustainable landscape and pest management practices. The program is administered by local University of California Cooperative Extension (UCCE) county offices that are the principal outreach and public service arms of the University’s division of Agriculture and Natural Resources.

The UC Master Gardener program supports sustainable gardening practices that protect the environment, conserve natural resources, and take into consideration each gardener's lifestyle and goals.

 

What do UC Master Gardeners do?

UC Master Gardeners are trained to help residents of California become better gardeners. Using a variety of activities such as workshops, lectures, and garden hotlines these volunteers answer questions about home horticulture, sustainable landscaping, and integrated pest management using University of California research-based information.

After their training UC Master Gardeners are qualified to help the public with problems in areas such as:

  • Weed Control
  • Plant Problem Diagnosis
  • Integrated Pest Management (insect and pest control)
  • Soils, fertilizers and irrigation
  • Selecting and caring for fruit and landscape trees
  • Growing annuals, perennials and food crops
  • Lawn care
  • Vegetable Gardening
  • Plant Pathology
  • Composting

 

Each county develops programs to address local needs. Some typical activities are:

  • Using mass media to disseminate gardening information
  • Teaching workshops, or lecturing on gardening practices
  • Participating in research activities with academics within UC
  • Answering gardeners’ questions via email or helplines
  • Speaking to the public on horticultural and gardening topics
  • Manning county fair information booths
  • Consulting with gardeners to improve their landscape practices
