Water Trees First
Our trees are the most important garden asset. They provide shade, clean the air, provide habitat for wildlife, they are beautiful and increase your property value.
A new way of irrigating trees have been developed by the University of California. As you see in the picture you will circle the tree with a drip line or soaker hose to the edge of the canopy. You can purchase supplies at your local garden center or hardware store.
To get the deep watering need for trees, you will need to run the drip line for several hours but only irrigate every 2-4 weeks. The water needs to penetrate the soil about 2-3 feed deep.

September in the Garden
What to plant:
- Cool-Weather annuals like pansies, violas, snapdragons can be transplanted now.
- Also, transplants of broccoli, cabbage, cauliflower, and kale can be planted this month.
- Direct seed peas, spinach, radishes, lettuce, and carrots.
- September is a good time to consider reducing the size of your lawn. It is also a good time to rejuvenate a lawn with over-seeding.
- Put your spent annual 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.
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
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
