Coir Vs. Peat

Coir

waste product
Shipped from India thousands of miles away,
equires lots of fresh water for cleaning
Coir is less acidic, and lasts longer
dispute about which one holds more water is pretty much irrelevant, since both hold so much water that as a soil amendment, both would dramatically boost soil water and nutrient retention.
Coir contains a great deal of lignin, which makes it very slow to decompose



Peat Moss

Peat bogs are valuable wildlife habitat, valuable carbon sinks, valuable water filters, Renewable?

Peat moss may acidify your soil enough that some of the more sensitive plants may need the soil to be neutralized before they can thrive.
Peat bogs are a natural carbon sink that hold more carbon than all of the world's forests
Peat bogs are also habitats, which mining disturbs.
Large bales of peat moss are cheaper
Liming to balance acidity – (MY NOTE: not a concern for LA as our water is alkaline and the acidity of peat might prove more benefical in the long run... )


The Canadian Sphagnum Peat Moss Association's study supporting peat moss as superior:

Syllabus: Container Gardening: Patios, Balconies, and Beyond; Summer 2013

COURSE SYLLABUS

Instructor: David King
Email: redacted 
Phone: redacted

COURSE TITLE AND NUMBER: Container Gardening: Patios, Balconies, and Beyond BIOLGY X 498.3

There are no prerequisites for this course. We will meet from July 1st through July 29th for 6 meetings. PLEASE NOTE THAT THE FINAL MEETING IS ON JULY 29th and credit students will have an assignment due. All class meetings, except for the one field trip (noted below) take place at The Learning Garden, located on the campus of Venice High School at the intersection of Venice Blvd and Walgrove Ave. You enter the garden on Walgrove, the first gate on south of Venice Blvd. Parking is on the street. The class will be held on the patio, the first night there should be signs indicating where to go.

Please remember when you are that close to the ocean, you will often have very cool evenings even on very hot days. Please keep a sweater or a jacket handy as we will meet outdoors.

Course Purpose

At the conclusion of this course, students will be confident in planting a multiplicity of containers with a wide variety of plants that will thrive in our unique climate. Students will be introduced to design principles applicable to container gardeners and will learn their care and maintenance.


Course Objectives

Students will be able to meet the following objectives by knowing:
Types of pots used in container gardeners
The qualities of the components of potting soil and how to choose a good one
Color combinations and other basic design principles
Care of plants in containers over their life span
Appreciation of light and water in container gardens
Students should also be able to report that they’ve been inspired to find their own individuality in container garden design and to experiment with colors, plants or containers that had been off their personal radar before this class. Students are expected to share their experiences and knowledge with the class which guarantees an enhanced learning experience for all of us.

Application

This course is designed to be applicable for home gardeners whether they are in a house, a condo or a town home; as well as professionals that wish to incorporate container gardening as a part of their business’ offerings. Students should also find time to do some networking with fellow students.


Text for this course:

Sunset Western Garden Guide 8th Edition, Brenzel, Kathleen Norris, Editor, ©2007, Sunset Publishing There will be no specific assigned reading from this book, but it is the “bible” for gardeners in Southern California.

In addition, the following texts are suggested for your reference shelf:
The City Gardener’s Handbook, Yang, Linda, ©2002, Storey Books, Published first as The City Gardener’s Handbook and then as The City and Town Gardener and now back again under the original title and now I see it back as The City and Town Gardener – whichever title you get, it is the same book.

Potted Gardens, Cole, Rebecca, ©1997, Clarkson Potter/Publishers

The field trip is on Saturdays, as indicated below.

Credit Students: Your grade will be predicated on class participation and a design project assigned at the first class meeting.

Office Hours

I have no set office hours, however, I am available by phone (the number above is my cell phone) and by email. I am willing to meet with students almost any day of the week at my office at The Learning Garden or a mutually convenient coffee bar. It is my most sincere desire that you learn and you will find me very approachable. After class is usually not a very good time because that’s when all students vie for answers and we are all tired after a long day. You can net a more thoughtful answer by contacting me another time.

Updates and Handouts

For this course I will utilize my personal blog page at http://lagarden.blogspot.com/ to post handouts and extra material for the class. There is an RSS feed through which each posting is automatically forwarded to your email so you can have access to handouts whenever they are posted. This approach is most handy when dealing with field trips because links to maps can be posted and any last minute updates are easily available. If this technology is new to you, another classmate or I will guide you through it. It is not difficult. If you miss a class or need an update, can't find your syllabus or whatever, you can find it here. You will need to, of course, bookmark it before you loose your syllabus...

Project Guidelines For Credit Students
Design a container garden with a minimum of five pots, any size (although five two inch pots won’t necessarily net a decent grade). Themed design.

Specify:
The purpose of the garden
Placement according to light
Other buildings or features that obfuscate or enhance light
Type of building; building color; building style
Interior style
Any particular facets of the owners’ personality that impact your design
How the owner will use the space
Plants used in each pot, by scientific name at least, indicate their water needs
What the pots are constructed of and their size (i.e. terra cotta) and design
How will they be watered?

Summary
I am looking for an understanding of what plants do well together (color, foliage, water requirements) and plantings that will enhance the building, style and owners’ lifestyle. I am also looking for appropriate design (i.e. no Phormium tenax in a narrow hallway). I have left this pretty open in hopes of accommodating a wide variety of interests and desires. If this is too open for you, I’ll be happy to fill in details that will narrow your focus.

I will endeavor to have tea or coffee available in the evening as there is no 'snack stand' near the garden. If you want to partake, bring your own cup and if you use sugar or cream, bring that too. Occasionally there will be baked goods, but no guarantees.  

Syllabus may be changed to reflect changes in reality. 

Bibliography for Container Gardening

Container Gardening, Elving, Phyllis, Editor, ©1998, Sunset Publishing, A small book withsome good ideas and at least it’s a look at the West Coast.

Potted Gardens, Cole, Rebecca, ©1997 Random House – I love her attitude about gardening and how she approaches the whole thing with a strong sense of whimsy and joy. Her gardening philosophy fits very well with my own. She writes a lot like I do.

Roof Gardens, Balconies and Terraces, Stevens, David ©1997, Rizzoli International Publications, Another ‘east coast’ book, but again the ideas and creativity are worth consideration as a starting point.

Sunset Western Garden Guide 8th Edition, Brenzel, Kathleen Norris, Editor, ©2007, Sunset Publishing All of the recent editions have their merit, but each successive edition has more plants and updates the scientific undergirding of gardening, so I encourage you to invest in the most recent edition you can afford (used copies are usually easy to find, either locally or at Amazon.com, I have a few for sale!). This is the number one go-to book for horticulture in Southern California; no other book is as authoritative as this one for our area. We cannot take advice from most gardening books and apply it to what we do in Los Angeles because our climate and soils are nothing like the rest of the world – especially those on the east coast and England where most books about gardening originate.

The City Gardener’s Handbook, Yang, Linda, ©1995 Storey Publishing, Although written for the east coast, this book’s ideas and principals are so clear and valuable, it stands out as one of my favorite references.
The Complete Container, Joyce, David, ©1996 Reader’s Digest Again, another focus on the east coast, but the ideas and plant lists in this book are better than most. It has pretty definitive instructions and is full of good clean photos. A good book to have – especially if you only buy one.

The Terracotta Gardener, Keeling, Jim, ©1990, Trafalgar Square Publishing, Not really a design book, but a historical perspective of terracotta used in English gardens and some background information on terracotta.

LA River Field Trip for May 11


Saturday is our field trip to the LA River.  We are going to a place on the river near Glendale.  The main reason to spend this time at the river is to acquaint ourselves with this tremendous resource that has been alternately abused and neglected; sometimes abused with neglect, sometimes just abused and sometimes just neglected.  Discussions abound about what to do with the river and I hope we take a few minutes to speculate about what the LA River could be like and how it could be a resource again; preferably ecologically so.  The Los Angeles River, unique among American rivers has one of the most precipitous drops in elevation in its 57 mile run to the ocean - AND it does so with a major population center sitting on its banks.

We inhabit LA largely because of this river.  We have disdained it and feared.  It would stand us all in much better stead to become at least familiar with it and perhaps even come to appreciate, if not love, it.

The address is 3900 Chevy Chase Drive, Los Angeles, 90039.

Twelve Points to a Better Organic Garden


“Patience may well be a virtue for the general populace, but for a gardener, it is essential.” David King, Gardenmaster

I have been a successful organic gardener in Southern California for the last twenty five years with a good deal of dirt under my nails on the mid-West plains before that. I have evolved a style of gardening that works well in Southern California and is 100% wholly organic and sustainable, as “sustainable” as a person can be in a land where water is shipped in from thousands of miles away. There are no books written for our climate that are truly organic or sustainable.

The principles that I use to guide my gardening are quite simple.

  1. Very little fertilizer. In fact, the fewer things you buy for your garden, the better off you will usually be. It is the task of advertising, with which we are constantly bombarded, to create the desire for a thing. I want to tell you that a few packets of seed, a couple of really well made tools and patience are all you need to grow good, nutritious, uncontaminated food. The scientific community, as far back as 1936 was aware that fertilizers, organic and chemical, were harmful to soil biota, the organisms living in the soil that make soil truly fertile. This understanding was deliberately not popularized because you won't buy something if you've already got it. No, you don't need fertilizer – you do need compost and lots of it, but you don't need fertilizer.
  2. No pesticides. In many ways, chemical pesticides are better for the world than organic ones because the chemical pesticides at least target the species that we wish to deal with while most organic pesticides kill everything they come in contact with while they are active. The key to a healthy, pest free garden is not through war, but through cooperation with nature. The entire key is to be attracting more insects to your garden – not less.
  3. Continuous cropping. Our gardens are small and the idea of crop rotation can be a little ludicrous. We need to have as much diversity in our gardens as we possibly can have – this means interplanting species and using legumes and other plants to keep the soil fertile for this constant cropping.
  4. Composting. Compost everything that can be composted. Everything ends up somewhere, if it will break down, compost it. If you lack space, vermicompost, but keep this valuable 'waste' out of the landfill!
  5. Mulch. Three inches in planting season, twice a year. This is the key to the soil's fertility and vitality. I use unfinished compost on top of my soil, in Fall and in Spring. Three inches!
  6. Insure the survival of pollinators. In this world of uncertainty, the roll played by pollinators has become more and more critical – plant your garden to provide for their well-being. And provide a source of water.
  7. Diversity in your garden. No matter how small your garden, you have room to plant a variety of species and should take advantage of that. Interplant everything to the degree you can (corn and garlic should have their own space, but for different reasons).
  8. Grow your own plants from seeds. Don't buy transplants from the nursery. Buy seeds and plant them yourself – there are good reasons to do this and the fact that it saves you money is just one.
  9. Saving seed to plant next year. And that means allowing some of your harvest to go to 'waste' in that some of your cabbages will flower, some of your lettuce will bolt and some of your cucumbers will stay on the vine well past the edible stage. These are investments in your future. This also means you will need to leave behind hybrid plants.
  10. Preserve and share your harvest - help someone else grow . Nature is lusciously abundant, emulate Her! Learn how to dry, pickle, can and freeze the food that is overwhelming you – if you can't do that, share it with your neighbor and make new friends. Teach a child the importance of gardening and how food really tastes.
  11. Don't stop learning. Go buy my book. Better yet, write your own book: keep your own garden journal and learn from your mistakes. Join a club, find a website or two, subscribe to a magazine. Garden in a community garden.

  12. Garden for yourself. Plant the foods you will eat or the foods you eat that are expensive or unobtainable in the market. Do not plant what the books tell you to plant if you don't like it, except you really should have some kind of legume – for you and for the soil. Above all, put a chair in your garden so you can sit with a cup of tea, coffee, a beer or a jug of water (is that really water?), and just hang out in your garden. You can use it to rest when you over-do it, or you can make it a place where you read a book. I love to have a bottle of sparkling water or a cup of coffee (depending on the time of day and the season), with my radio tuned to the Dodger station and my notebook in hand. Some of the finest moments of my life have been spent this way – certainly, some of the most peaceful! Make your garden a part of your life, just like your living room is! Ditch the TV, watch insects fight for their lives in your garden, butterflies, bees, hummingbirds and other critters doing their daily chores in your garden. It is peaceful and oh so refreshing.
And take care of yourself while you garden. Drink plenty of water (that's the best), protect your skin from the sun with long sleeved shirts and a hat. Stop to catch your breath and look around, your garden will soon team with life so get to know it and don't fear it.

As a society, we have left so much of this behind. Don't get so caught up in 'working' on your garden, that you miss the peace and wonderment of watching Nature do her thing right in front of you. Allow the garden to be so much more than just a place to 'make food.' A garden can heal. Let it happen for you!

Easy Native Plants Lecture, Thursday 7:00 pm, Brea

I will be speaking for the Rio Hondo Group of the Sierra Club, Thursday May 9, 7:30 pm, Dinner at 7:00 pm. Please plan to order at least a coffee if you are coming. I will be doing my 'Easy Native Plants' Lecture. The Coco's Restaurant where they meet is at 1250 E. Imperial Hwy, Brea 92821    Their phone number is: (714) 990-0671

Reading List and Resources for Sustainable Water

Handout from Water Saving Strategies Lecture at Saddleback College; somewhat cryptic: http://nativesanctuary.files.wordpress.com/2009/09/water-saving-strategies-handout.doc

Mulch Suppliers that deliver:
Soil and Sod, Pacoima, 818-686-6445
Foothill Soils, Sylmar, 661-254-0867
 
Rainwater catchment supplies from Gardeners Supply (also upscale but small tanks):

Tanks (Tank Depot) choose tanks that ship from CA. Also sells first flush systems. Etanks is another option.

California Native plants that can be used as lawn:
Carex praegracilis: Clustered Field Sedge, more runner-forming and faster cover than Carex pansa, which is also sometimes sold as a lawn alternative.
Festuca rubra: Red Fescue, the lumpy lawn, requires much more water than above, but easily available in conventional nurseries.
Bouteloua gracilis: Blue gramma grass is also very lumpy, looks like a bluer Bermuda, great for desert/hi-elevation applications.

Books and other resources:
Shawna Dark et al,  Historical Wetlands of the San Gabriel River   I believe this is the newest link to the above research showing how dewatered the landscape of the San Gabriel River watershed has become in the last 100 years.

Art Ludwig
You can buy books, plumbing supplies, etc. from this website, http://oasisdesign.net/. Reading the articles on the website is an education in water storage and reuse. The only source of salt-free dish and laundry cleanser that I am aware of, "Oasis Biocompatible." Remember, all "natural" or "biodegradeable" detergents contain Sodium as a major ingredient, thus are bad for your soil.

Ludwig, Builder's Grey Water Guide, Oasis Design

Another excellent resource for water use.
Lancaster, "Rainwater Harvesting for Drylands" Vol 1 & 2, Rainsource Press
Vol. 1 is overview, Vol. 2 is earthworks

Mollison, Mia Slay, "Permaculture: A Designers' Manual," Tagari Publications

Hemenway, "Gaia’s Garden," Chelsea Green, especially good for theory of constructed wetlands
