I took my usual walk through local neighborhoods surrounding Balboa Park in San Diego. A glorious spring day, I couldn’t help but marvel at the beautiful ornamental landscape trees, shrubs and vines in bloom everywhere! Very uplifting, glad plants are not affected by the virus!

Not a field of poppies but still…

Wow

“Arborgeddon” – PTCA Hosts Another Great Seminar and Field Day
The Professional Tree Care Association (PTCA) of San Diego hosted their annual seminar and field day, a two day event on Friday, August 22 and Saturday August 23, 2014. This was the 25th annual event and like many of the previous seminars, this was another informative, educational experience bringing together a wide diversity of speakers and audience!
The seminar was on Friday and this years theme centered on the ongoing California drought and ramifications to trees. There were a number of great speakers, starting with Mr. Ron Matranga who provided an overview about trees in times of drought, current and future water restrictions . Dr. Roger Kjelgren, Professor from Utah State University, provided a simplified method for landscape irrigation demand estimation. Dr. Linda Chalker-Scott, the Urban Horticulture Extension Specialist from Washington State University discussed how to treat and avoid drought stress in landscape trees and Ms. JoEllen Jacoby, the Water Conservation Landscape Architect for the City of San Diego enlightened us about planning for current and future water restrictions (gulp, better get some rain this winter)!
Ms. Mary Matav, Agronomist from Agri-Serve presented information on how to combat pests and drought, followed by Dr. Tracy Ellis, Entomologist with the San Diego County Department of Agriculture, scaring all of us about tree insect interceptions and quarantines in San Diego County.
A great roster of speakers who delivered relevant information in a beautiful setting at Balboa Park in San Diego. On Saturday, the event transferred to the field, where information discussed at the seminar was applied and viewed in the field, an aspect of the field day I find very beneficial.
As usual, Dr. John Kabashima, the Environmental Horticulture Advisor with the UC Cooperative Extension, presented new, current information on the latest insect threat to our ornamental and agronomic trees in California, that being the Polyphagous Shot Hole Borer, (PSHB). As many of us already know, this destructive ambrosia beetle is now active throughout the Southern California.
The PSHB is an invasive ambrosia beetle that carries the fungus Fusarium euwallaceae. The female tunnels through the bark and lays galleries of pre-fertilized eggs and grows the fungus, which becomes food the newly hatched beetles. The fungi infects the tree with a disease called Fusarium Dieback (FD), which interrupts the transport of water and nutrients through the vascular system of the tree. In essence, this is a vascular clogging disease resulting in dieback and death of a large host of trees. Unfortunately, there is no cure at the present time and beware of PSHB/FD look-alikes. Here is very informative attachment Dr. Kabashima provided that really provides current information about this insect. Handout is published from the University of California and the UC division of Agriculture and Natural Resources. PSHB Information
Many thanks to all of the hardworking voluntary staff of the PTCA. What a great local association, I am very proud to be a member of. The PTCA is an active association promoting the best in tree care and tree knowledge. An association composted of tree care companies, certified and consulting arborists and tree care professionals, the PTCA continues to provide current and relevant topics for it’s membership and community at large. Thanks again PTCA, looking forward to next years Seminar and Field Day!
Winter Sweetness!
Talk about a winter treat, try growing your own semi dwarf citrus tree(s). Last year, I planted a 15 gallon “Satsuma” seedless mandarin orange and one year later, we are feasting on an amazing harvest of sweet, juicy seedless mandarins. Try using mandarins in salads and dressings, not to mention fresh off the tree anytime!
I found the plant fairly easy to grow, full sun with normal fertilization and decent drainage. I kept the soil pH on the acidic side, the plant did great. I strongly recommend this particular variety because it stays relatively small, easy to maintain, and heavy fruit production.
Late fall / winter maturing citrus is such a special treat to have in Southern California. Just imagine all those mid western and eastern folk never having the opportunity to grow and have fresh citrus like we do!
With many varieties to choose from, you can select a tree that suits the size of your property. A nicely maintained citrus tree can be a very attractive small to mid size tree with the added fruit as a tremendous benefit.
Enjoy!
The Edible Landscape
In Southern California, we are blessed with a mild, Mediterranean climate that provides a 365-day year growing season. Although limited by some winter frosts, we are able to grow most landscape ornamentals as well as vegetables throughout the year.
We also face serious water supply challenges now and into the future. Water allotments from Northern California and the Colorado river are being reduced, municipalities have issued water alerts and restrictions on water use while implementing tiered water rates meant to punish abusive water consumers.
The days of cheap imported water that allowed Southern California to flourish as a green oasis in what normally would be a desert are ancient history.
If you are considering a new or renovating an existing landscape, water conservation and using appropriate plant materials should be a top priority. Studies show 50% of a residential water bill goes toward landscape irrigation. The single greatest water consumer is turf grass utilizing overhead spray irrigation.
Do you really need that turf grass lawn? Are you an empty nestor, no longer needing the big play area for the kids? Are you a new homeowner, trying to figure out the best design and functionality for your landscape? With todays water and maintenance costs, you must make an informed decision when tailoring an appropriate landscape for your property and your own personal, functional and aesthetic interests.
So, if you have already decided the typical water guzzling turf landscape is not for you, that leaves several types of water efficient landscapes to choose from. This blog will focus on using an organic fruit and vegetable garden as an edible, beautiful and functional landscape planting.
ARE YOU THE GARDENING TYPE?
If you:
- Love to get your hands dirty
- Have the time and commitment to garden regularly and as needed
- Have a area that receives a minimum of six hours full sunlight daily
- Enjoy eating fruits and vegetables
- Have a desire to eat chemical free produce
- Enjoy saving water cost, reducing your carbon footprint
- Like to educate kids, neighbors and your community
- Like to do the right thing
If the answer to the first four items above are yes, Congratulations, you are a likely candidate to start a fruit and vegetable garden!
The traditional concept of row gardening can be easily modified and adapted to a landscape design, satisfying both functional and aesthetic considerations. Using our residence as a example, we choose to convert our worn out, old front yard cactus garden into a fruit and vegetable garden.
Overgrown, non functional cactus garden
Since this is our front yard, I wanted to create a functional yet aesthetic fruit and vegetable garden that would enhance and enliven the site characteristics. Since the site is raised and already had a segmental block retaining wall, I designed a series of raised planters with pathways on each side of the planter for ease of cruising through the garden and access to work both sides of the planter beds.

Raised planters with pathways for access also create interest
In a few months, we celebrate our one year garden anniversary. Take a look at some of the fruits and vegetables grown this past year.
