UCCE MASTER GARDENER ADVICE TO GROW BY WORKSHOP
Held: JUNE 19, 2010
Selecting the right subtropical tree for your climate: Some varieties are more tolerant of our “cooler” conditions during the foggy summer months. Varieties that require a lot of heat may never ripen. Rule of thumb – the more acid in the fruit, the less cold tolerant.
CITRUS VARIETIES - see last page for San Luis Obispo County
Citrus for the Home Garden in Contra Costa County http://ucce.ucdavis.edu/files/filelibrary/434/32989.pdf
AVOCADO VARIETIES – see last page for San Luis Obispo County

Select the best location in your yard and recognize micro-climates that occur even in small areas:
To protect your trees from frost.

Water needs and irrigation of citrus and avocado:
Mature trees in warmest months will need 60 gallons of water/week.

Weed Management for citrus and avocado:
Both citrus and avocado are very shallow rooted – only hand weeding and mulch underneath trees
Weed identification and control measures: http://www.ipm.ucdavis.edu/PMG/menu.weeds.html
Fertilizer requirements for citrus and avocado
Suggested application rates of nitrogen - Divide into 2 or 3 applications
- 1st year: 1 tablespoon nitrogen fertilizer 3 times per year, per tree.
- 2nd year: 0.25 lb actual nitrogen per tree
- 3rd year: 0.5lb actual nitrogen per tree
- 4th year: 0.75lb actual nitrogen per tree
- 5th year:1 lb actual nitrogen each year
|
1 pound of actual nitrogen equals about 5 lb of ammonium sulfate (21% nitrogen) per year, or 100 lb of composted cow manure each year. Organic fertilizers such as manure, bloodmeal, etc. could be applied in the fall under the tree canopy.
Pest identification, including methods of reducing pest populations using the least toxic methods.

Q We so often hear the word sustainable these days, from various sources and seemingly with various meanings. We do care about the environment but are not in a position to completely renovate our landscape and garden. Can the Master Gardeners offer an approach to sustainable gardening, or some specific practices which we can begin to use right away?
Paul and Mary Kubacki - San Luis Obispo
A An approach to sustainable landscaping recommended by the University of California Cooperative Extension includes practices developed by the Sacramento Stormwater Quality Partnership with permission and assistance from StopWaste.org in Alameda County.
Most gardeners should be able to implement these practices immediately and relatively easily, and save energy, water, time and money.
Benefits of sustainable practices can be felt in our own households; the environment benefits from such practices adopted throughout watersheds, and the cumulative effects may be significant.
Landscape in harmony with natural conditions of the site, watershed and climate.
Maintain fire safe landscaping, protect local flora and fauna, and utilize site-adapted plants, ideas for which can be seen at Cal Poly's Leaning Pine arboretum and at
http://arboretum.ucdavis.edu/arboretum_all_stars.aspx
* Landscape for less to the landfill
Use plants of sizes which match their intended space to reduce pruning; grasscycle; compost; and incorporate salvaged hardscape materials where possible.
* Nurture the soil
Save topsoil, mulch, avoid use of quick-release inorganic fertilizers and use pesticides as a last resort.
* Conserve water
Minimize turf, group plants according to water needs, and maintain efficient irrigation systems.
* Conserve energy
Plant trees to minimize energy use. Shade paved areas. Shade south and west sides with deciduous trees. Design outdoor lighting carefully.
* Protect water and air quality
Utilize Integrated Pest Management; minimize impervious surfaces; prevent runoff; use appropriate equipment.
* Create and protect wildlife habitat
Maintain diverse plantings and utilize natives. Provide water and shelter. Conserve or restore natural areas and wildlife corridors.
Please contact Master Gardeners for much more related information and detail.

Learn how to Build Raised Beds!
Click HERE to find a great step-by-step instructions by Sunset on building your own raised bed!
The Benefits of Raised Beds
- They warm up and dry out faster in spring, so plants get a jump-start on the season.
- You can grow more vegetables in less space and have less area devoted to paths.
- They create attractive, well-organized planting areas.
- They save on the amount of fertilizer and compost used because it's concentrated just on the planting beds.
- It's less work, especially if you make permanent raised beds bordered with wood, bricks, or stone. You won't have to remake the beds each spring.
- The plants will have healthy root systems because you won't be stepping on the planting bed, compacting the soil, and making it hard for roots to grow.
- You can be more creative with design, making round raised beds for example, and planting vegetables, herbs, and flowers in various designs on the raised beds.
- It's easy to plant climbers such as cucumbers up an A-frame trellis because it fits nicely over a 4-foot bed.
- It's easy to fit season extenders such as row covers with wire hoops over the 4-foot beds.
- Raised beds are designed with the human back in mind – less bending and stooping over.
- Lower maintenance for weeds, watering, pests and replanting.
- You’ll have more control over your soil mixture and you can easily change the soil texture, fertility and tilth.
- Ability to add gopher wiring and copper barrier around edges easily.
- Raised beds are a good way of balancing nature’s resources.
- They're beautiful!
Soil Information
Key points - good drainage for proper aeration and organic matter, organic matter, organic matter!
- Decide whether to use an amended garden soil and organic matter or a growing media like potting soil with amendments.
- Mix the top several inches of native soil with several inches of whatever you put in the raised bed to prevent abrupt soil boundaries that could impede drainage.
- Put down hardware cloth to eliminate gophers.
- Very sandy soils or soils high in clay will have the most benefit from organic matter amendment.
- If you use garden soil, double dig the planting bed to make sure that amendments and organic matter are uniformly mixed.
- Aim for at least 4 to 5% organic matter to soil ratio, good compost works well (good compost doesn't look like the original materials, but has a dark rich appearance and a moist, crumbly texture.)
- Add 2 to 3 inches of compost for every 6 to 8 inches of depth and mix well. 3 cu. yds of compost covers 1000 sq ft 1 inch deep
- Check the pH in the root zone after a week or so - should be around 6 to 6.5. Lime or sulfur can be used to adjust pH up or down, respectively.
- Leave at least 2 inches for a mulch on top of the beds
Other issues to consider:
- Peat moss is often mentioned as an organic matter addition - is this a sustainable amendment?
- Manure also mentioned as an organic matter addition –it can add salts to the bed and should not touch the edible parts of the plants.
- Good quality compost (fully composted, no large pieces of woody material) is best and sustainable.
- Vermiculite and perlite are also referred to as good soil amendments- they can be costly for large beds but may be reasonable for smaller units. They are also very light and tend to rise to surface and wash away.
