October in the Garden

 

What to plant:

Þ Cool-weather annuals like pansies, violas, snapdragons can be transplanted now. Also, you can direct seed cornflower, nasturtium, poppy, nigella, portulaca and sweet peas.

Þ If you don’t have a winter garden, consider planting a cover crop to be tilled in next spring.

Þ Direct seed peas, spinach, radishes, lettuce, and carrots.

Þ Early in the month you should buy your new bulbs and refrigerate them for six weeks before planting them in the garden.

  • October is also good time to consider reducing the size of your lawn. You can still rejuvenate a lawn with over-seeding.
  • Put your spent annuals and vegetables (disease-free, of course) in your compost pile.
  • Add compost to the beds that had the annuals and vegetables you are pulling out, before re-planting in those beds.
  • This is also the month to dig, divide, and re-plant overgrown perennials that have finished blooming. Be sure to clear out any weeds that developed in the perennial bed.
  • Check azaleas, gardenias and camellias for leaves yellowing between the veins. Apply chelated iron if this condition is present.
  • If you had glads, dahlias or tuberous begonias they should be dug up and cleaned after the foliage dies. Store the corms and tubers in a cool, dry place.
  • Be sure to deadhead your roses following the October bloom.
  • Keep your compost bin covered with a plastic tarp when rains begin.

 

 

Drought Advice

 

CONSERVE WATER

Create drought resistant soil

  1. By incorporating 2-4 inches of compost into the soil you will increase the water holding capacity of the soil.
  2. Topdressing compost around plants will reduce water needs but not up to the plant base.       Space @ the base.
  3. Mulch all exposed soil to reduce evaporation with bark, leaf litter or rocks
    Mulch

Benefit:

  • Reduced water usage

 

Grow California or Mediterranean natives

Check out the UC Arboretum All-Stars

  1. Plants thrive with little irrigation
  2. Planting in the fall allows the roots to grow without competition
  3. Irrigate until established
  4. Minimize high water use ornamentals

Benefit:

Cal Iris

  • Reduce watering
  • Reduce trimming
  • Reduce fertilizing
  • Reduce spraying

 

Minimize the Lawn

  1. The use of native groundcovers, grasses, shrubs and trees make an eye catching garden
  2. Reduce the size of the lawn and plant Tall fescue. It is a cool season grass that does well in summer. Most cool season grasses need a lot of water to look good
  3. Avoid slopes, plant a ground cover instead of lawn

Benefit:

Min lawn

  • Conserve water
  • Conserve energy
  • Conserve labor        

  

Hydrozoning

  1. By grouping plants together by water and light needs plants tend to be healthy
  2. When you group your plants together by water and light needs then you can properly water each micro-climate
  3. Use California natives

Benefit:

  • Healthy plants
  • Conserve water
  • Less pruning

 

Irrigation System

  1. Remember to change your irrigation timer seasonally. Monthly adjustments are encouraged
  2. Use an automatic controller on your irrigation system
  3. Use drip for your flower and shrub beds
  4. Replace old sprinkler heads with high efficient ones. If your system is over 10 years old check out the new sprinkler heads at your local garden center
  5. Use multiple run times if you have a lot of run-off before the timer shuts off.  For example; you should irrigate every other day for 20 minutes but after 15 minutes the water is running off the lawn. Instead run the system for 10 minutes, wait 1 hour and run for another 10 minutes. This works especially well on slopes.

Benefit:

  • Limit evaporation and run-off
  • Limit disease
  • Limit weeds

 

Irrigate according to the season

  1. Know your watering needs (Lawn water kits are available in our office)
  2. Adjust watering to the season, use chart in Lawn Watering brochure
  3. Water early
  4. Water slowly
  5. Water deeply

Benefit:

  • Appropriate watering slows plant growth
  • Promotes plant health
  • Reduces pruning and mowing
  • It is estimated that overwatering causes 85% of all landscape problems

 

Make every Drop Count                 

  1. Water wisely and slowly.
  2. Mulch is one of the quickest, easiest and most cost-effective ways to save water
  3. Repair leaks and broken sprinklers
  4. Reduce overspray areas
  5. Adjust the system frequently to the season
  6. Mulching exposed soil reduces evaporation.
  7. Prevent urban drool

Benefit:

  • Conserve water
  • Save money
  • Urban landscape water use can be reduced by 50%

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
