April in the Garden
What to plant?
- In a shady spot early in the month you can still plant pansies, violas, and primroses.
- You can plant dahlia tubers and transplant most perennials.
- As temperatures warm (nights consistently over 55 degrees) you can transplant tomatoes, eggplants and peppers.
- You can still plant seeds of cilantro, radishes, beets and chard. (Cilantro will go to seed quickly as the weather warms up.)
- Fertilize shrubs and trees once this spring.
- Watch azaleas and camellias for yellowing between the veins in the leaves. If the leaf is yellowish, apply chelated iron to the plants.
- Trim the dead flowers but not the leaves from spring bulbs. The leaves restore the bulb; so wait to remove them until they turn yellow. Fertilize the bulbs after the bloom is finished with bone meal.
- Apply organic mulch to all beds to keep the soil cool and enrich the soil.

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
