Hi Everyone,
I love this rain. Hard to believe it is only 8 weeks to summer, I feel as though we haven’t had a spring as yet. I had a stall at Hulbert Street on the weekend. What a great weekend and a great festival. The highlight of the weekend was the “couch race” on Sunday after the festival was over. John, who lives close to Hulbert St, makes all these machines out of lounge chairs, bath tubs, wooden carts, old motor cycles and whatever takes his fancy and at the end of the weekend when all the stall holders have gone all the kids grab a machine and race down the street. It is really a sight to see. Thanks to Shani, from the Painted Fish, all her volunteers that helped during the weekend and to all the residents on Hulbert Street for a terrific weekend.

Charles, from our Gwelup group and Permaculture West, has been working hard organising talks and displays for the sustainable section at the Royal show. Come along and see all the hard work that Charles and all his helpers have done and show them your support. To find out more information go to this web site http://permaculturewest.org.au/news/royalshow2011
The OGAWA Organic Festival is on again. This year it is Saturday 15th October at Perth City Farm from 8.00am till 2.00pm. We have special guest speakers throughout the day, Perth City Farms Farmers Market is on and there is also an Artisan market happening as well. Lots of Kids activities, extra stalls and plenty of taste testing, including wine. So come along and support OGAWA and all our commercial members.
One more event on the 15th October is our AGM at 9.00am, we will be done by 9.30am. Every year we ask the same question, HELP WANTED. We really would like to see more people put their hand up to help us go forward. We have a few more ideas we would like to get off the ground but unfortunately we are light handed. We meet every 3 months, the rest of the time we do business through emails. If we could have a few more helpers we would be able to have OGAWA seen more. Those of us who are putting our hand up are keeping the Association going, but we are unable to expand, so please see if you have a few hours free every month to help this great Association.
On that note, I shall bid you farewell and see you all on the 15th
Cheers

Organic Farming is Superior to Conventional Agriculture According to 30-Year Comparative Study
Rodale Institute announces the latest results of the Farming Systems Trial, America's longest running side-by-side comparison of organic and conventional farming practices. The Farming Systems Trial shows that organic farming is the healthiest and safest way to feed the world, provide much-needed jobs, reduce our greenhouse gas emissions and protect precious natural resources.
Key findings show:
-
Organic yields match or surpass conventional yields.
- Organic yields outperform conventional yields in years of drought.
- Organic farming systems build rather than deplete soil organic matter, making it a more sustainable system.
- Organic farming uses 45 percent less energy and is more efficient.
- Conventional agricultural systems produce 40 percent more greenhouse gases.
- Organic farming systems are more profitable than conventional farming systems.

On 17th September we visited the holy monastery of St. John in Forrestfield. Stan Kailis who also arrange this visit introduced us to the monks who later gave us a short overview of Greek Orthodox Religion and the history of the monastery. We then toured the grounds and visited the vegetable garden, chook shed, said hello to the donkey and had a look at the new olive grove. Stan gave us a told us the story about the olive grove and shared his amazing knowledge on olive trees with us. We then proceeded to the “café” where we had some delicious snacks and teas and lots of chats. The monks were quite thrilled and have enjoyed our visit. I would like to thank the monks for their hospitality and Stan for organising the visit to the monastery.
The next meeting is going to be on 13th October at the Meeting Place. It will be an informal meeting and any thing you would like to share or questions you have about your garden can be answered.
Kind regards
May-Ring and Margaret

Hi Everyone,
We had 2 good visits in September. First of all a few of us joined MOGG and went to their “seed-in” and secondly we visited the Greek Monastery. It's always great to see what others are doing and get new ideas. Sue Hartley is opening her permaculture garden to the public under the Open Garden Scheme October 1-2, a garden really worth seeing!! Her address is 33 Lisle Mt Claremont. There will be lots of talks and I will be speaking about sprouting on Sunday arvo if you are interested.
DEVELOPING A BUSHFIRE SURVIVAL PLAN
If you live in on or near bushland, you are at risk from a bushfire and developing a bushfire survival plan is critical.
Being prepared for a bushfire can help save you and your family’s lives, your property and your livelihood.
Are you and your family at risk?
You need to think about the bushfire risk to your family and home:
- Do you live in or near bush?
- Does your local area have a bushfire history?
- Do you have trees and shrubs within 20 metres of your house?
- Is your house built on a slope?
- Is your bushfire survival plan more than one year old?
|
|
If you answered yes to one or more of these questions then being impacted by a bushfire is a real risk to you and your family. You need to have a bushfire survival plan and keep it updated.
When developing your plan decide together if you will leave for a safer place, which may be to relocate to family or friends, or stay to actively defend your home. Make sure you write everything down.
Keep your bushfire survival plan in an easy to find place and make sure everyone knows where it is.
At the October meeting of the Roleystone Organic Growers Chris Cairns from the Roleystone Volunteer Fire Brigade will be discussing how to develop a bushfire survival plan and we will meet in small groups on the night to share ideas.
Chris has a wealth of knowledge and experience. She has been in the Roleystone Volunteer Fire Brigade as a fire-fighter for 16 years, Bushfire Ready educator, part of the emergency response groups and been involved with Juvenile and Family Fire Awareness Program (JAFFA).
The meeting is on Wednesday October 12th at 7.30pm in the Roleystone Family Centre, 19 Wygonda Rd, Roleystone. Entry $3-members free.

Seed in for summer planting
|
 |
Message from Ralph Darlington |

|
|
Hello everyone.
Last month was quite a busy month. On Sunday the 3rd, we held our seed-in for summer plantings. Members of the Rolystone Group joined us as did Tanya from the Freo Group. It turned out to be a lovely sunny day after some threatening clouds. Much chat, and planting into seed raising mix went on, as did the swapping of seeds between us.
The ‘Mundaring mob’ also put in extra seeds to be given away as seedlings, at the Whim Festival which is to be held at Mount Helena on Sunday the 23rd of October. We are having a stall where we will answer questions about organic Vege’ gardening and give away these seedlings. We will also have a table to encourage children to plant seeds provided, into a punnet to grow.
This is to be part of raising the awareness of Organic Gardening in our area, and of course encouraging membership in our group and OGAWA.
The speaker at our last meeting was David Williams who spoke on Bio Dynamic growing. The mysteries of the various preparations and stirring techniques were explained as were insights into ‘broad acre’ techniques of weed and parasite control was very interesting. Much of the information could be modified to our own gardens.
Next month our meeting is a group one, were we will run a Q&A night and finalise arrangements for the Whim Festival.
Regards,
Ralph Darlington

Nola's garden |
 |
Message from Charles |
 |
|
We gathered at Nola’s in Victoria Park on an almost warm Saturday afternoon for our last winter meeting. A few patches of thriving nasturtiums add colour and distract some of the pests, similarly the marigolds in and amongst a few eggplant and capsicum that have grown through winter.
We prowled around amongst the onions, garlic, fennel, parsnips, spinach, collards, kale and lettuce and checked out the first pods forming on the broad beans plants which have to reach high to get the sun during winter. The Chinese cabbage has run to seed in and amongst self sown dill, lettuce and parsley. The new herb gardens among the citrus trees haven’t yet developed – the vision is a type of knot garden, planted with Mediterranean herbs that will survive hot summers in sandy soils – borders of different types of lavender plus rosemary are starting to grow.
Pam had experimented by recycling lengths of hessian as weed mat, mulch and moisture saver . Results have been good. Pam is also trying to deter ants from aphid farming in her citrus trees by putting a wide (about 10cm) band of Vaseline around the trunks/branches.
Joe’s patch has been yielding good garlic, he has dwarf citrus in pots and we discussed citrus pruning strategies in general - such as removing a little of the older wood to encourage new growth as well as removing/trimming very vigorous watershoots from citrus. General thinking was that citrus need to be around 4-5 years old before they produce regular crops – so next year Joe! His pond is established and doing well – it’s a kidney shaped pond which he’s extended with plastic. He debarked a log and has drilled holes into it to encourage native bees. He’s included running beans in plantings around the pond. Feedback from Joe’s visits to other workshops includes the importance of boron to set fruit – in addition to potassium. This is especially important for beetroot. |
Wendy’s plan for growing veggies in pots in her sunroom is developing which led us into a conversation about good resources for organic gardening in containers. Peter Bennett’s ‘Organic Gardening’ was recommended plus the website beyondgardens.com.au (recommended as a good website for lots of organic gardening ideas). Around this time we discussed the benefits of nasturtiums as a useful addition to mulch and compost as a way of returning minerals and other goodies to the soil – in addition to nasturtiums role in attracting some of pests.
Michelle provided information about Perth Edible Gardening on Facebook. It’s a closed Facebook forum which means that participants have to be nominated/accepted by a member. The site is a virtual space to exchange information and ideas about edible gardens with enthusiastic WA gardeners. Joe and Michelle are members. Request access via messaging Charles Otway in Facebook. Other interesting options are the Open Garden Scheme (see their website for more info) – Michelle will circulate further information to the group. Many thanks Michelle.
Mike and Di gave a run down on their garden, their passion fruit has produced a winter crop – word is that while winter fruit may not change to the purple we’re used to; they will ripen and by around October should be ripe inside even if the fruit are still green.
We ended by exchanging ideas about watering strategies. Michelle has found that she can adapt a watering wand from the hardware store by removing its sprinkler head which then leaves a hollow metal wand which she can push into the ground to get water to the root areas of plants. We noted that plastic pipes have also been dug into the ground to help get the water below the surface.
Our next meeting will be on 29th October. charles@permaculturewest.org.au or 0466633275 |

Snake bean seedlings
|
 |
Message from Tan Fowler |

It was a very quiet meeting this month; I think everyone is probably a bit burnt out after all the events of the last couple of months!
The topic was extending the growing season, very appropriate this time of year as the temperature starts to rise and the fierce sun is starting to return. There were three main points
1) get rid of abundance! Have a think about how much you are actually eating and if there is more than you need remove anything that is starting to flower first and then just thin the patch. Abundance will breed up bugs and starve plants of the nutrients they need. If you have a Kang Kung patch get in there and cut out any damaged old growth.
2) Shade! If you can put some shade cloth over your leafy greens. This is too difficult for me so I try to companion plant and let the plants shade each other.
3) Plant for the wet season. Now is a great time to get things established. It’s warm enough for all the tropical species but we still (hopefully!) have a little bit of time before it’s too hot! I've been planting Thai green eggplants,
3 varieties of chilies, snake beans, angled loofah, zinnia, Thai basil and lab lab bean (ground cover for beds I won't use over the wet season). Others are sweet potato, kang kung, loofah and Vietnamese mint.

Sorry I missed the report last edition. We had a great visit to the Broome Organic Gardens, a 12 acre 12 Mile property established in 1988. Wayne has turned his patch of savannah into a tropical food forest. There was too much information for me to give you all now but I will mention the plants he is growing; black Sapote, Avocado, edible taro, coconut, starfruit, jackfruit, mango, banana, papaya, cardamom, 40 varieties of bamboo, 8 types of boab, a variety of herbs and vegetables, and quite a few rare plants such as Frankincense and Asha nagenda (not sure about the spelling) commonly known as Indian ginseng.
An interesting fact I learnt was that Lord Mac Alpine brought the Malaysian Blue earth worm into Broome which Wayne proudly calls his secret workers. Wayne’s main tip was water! Unless you have the irrigation worked out don’t bother.
I will be away in October so no meeting at 12 Mile Café. If anyone would like to host the meeting which would be on the 15th of October let me know by email;

After the lean times of winter the bounty of spring has arrived. We've now got a huge range of fresh herbs from Broome and various other growers. The local Asparagus is in full swing now and as well as a few different varieties of Kale. After being really short for the last few months the Queensland Celery season has arrived and it’s looking really nice and fresh.
Bananas are now coming down in price and hopefully will stay there. Broome mangoes are not too far away and the local Valencia Orange season has just started, but the most exciting thing in the fruit basket at the moment are the juicy, fresh local Strawberries - I’m eating one as I write this. |

| Gardening report from Linda Mitchener from The Green Life Soil Co. |
Hello again. I hope you've been enjoying time in the garden this Spring. The good rain followed by lovely sunny days has meant plants have been springing out of the ground. Especially the weeds at our place!
This is the perfect time of year to be growing heaps of summer vegies and salad greens. It’s not too late to get planting. Remember to improve your soil with compost and aged manure, and incorporate rock dust to provide trace elements. Water well and leave to settle for about a week if possible.
Whether you choose to grow from seed or seedlings, there is a huge variety of things which will grow well now over the next few months, including Artichoke, Asparagus, Basil, Beans, Capsicum, Carrot, Celery, Chilli, Choko, Coriander, Eggplant, Leek, Lettuce, Peas, Pumpkin, Radish, Rockmelon, Silverbeet, Spinach, Sweetcorn, Tomato, Watermelon and Zucchini.

Improve your soil with compost an
aged manure
|
Most seeds need constant temperatures of between 18 – 25 degrees to germinate, so depending on where you live, we are starting to approach this. But remember soil temperatures are lower than air temperatures, so you may wish to start seeds off in seedling trays you can move around to ensure seeds are kept warm enough. Remember to keep an eye on moisture levels. As a general rule the smaller the seed, the more water may be required – often you are best misting regularly with a spray bottle or setting up a simple wicking system. It is as bit of a trick to ensure the seed is kept moist but not waterlogged. On our website we have a downloadable ‘When to Sow’ chart that incorporates a seed germination guide. Temperature & moisture problems, and sowing too deeply are three of the main reasons why seeds fail to germinate. As a rough guide seeds should be sown to a depth of two/two and a half times their diameter – so you can see that is not very deep given that most seeds are quite small. Small seed can be placed on top of soil and JUST covered with a sprinkling of sand or fine compost. While germination rates vary greatly, as a very general rule most will germinate within 10 – 14 days. However, don’t get impatient and throw them out day 15 if they haven’t popped up!
Personally, I like to grow from healthy seedlings to avoid the uncertainty and for some instant gratification (OK, the secret’s out - I’m a lazy gardener). We have a lovely range of Certified Organic summer vegies becoming available, with the range increasing every week. We also have loads of non-hybrid tomatoes, and many herbs which make great companions for them.
So if you've been thinking about giving Organic Growing a go –now is the perfect time. Even if you start small with a 1m x 1m plot, you can be enjoying your own healthy salads within a few weeks!
Until next time, have fun in the garden!
Linda
Until next time,

We all know that GM canola cannot be segregated or controlled and this has been highlighted by the recent finding of GM canola growing wild along the roadways outside of Esperance. Last year that area saw 30 farmers grow almost 8,000 hectares of the crop so it is not surprising that some of the seed has escaped and is now growing along the highways. The situation will only worsen as this year 38 farmers are growing GM canola in the area.
Of course this will be replicated across all GM canola growing regions and where ever trucks carry the GM seed. It has been said that if a truck leaks water it will leak canola.
During the 2009 GM canola trials the state government insisted on taping trucks to prevent such escapes to show its ability to successfully segregate. Although this clearly did not replicate normal practice it should have continued even when the trials finished.
Apart from having GM canola growing wild and being a clean-up burden on local councils there is a more worrying part to this scenario. Canola is part of the brassica family, and shares its genes with broccoli, cabbage, brussel sprouts, bok choy and many others. What happens when wild GM canola cross-pollinate with their cousins? Crossing does occur, so how do we protect our brassicas, especially if they are organic? This appears to be another area that the State Government has not investigated, although I am sure their response would be to allow some level of GM ‘tolerance’ as has been suggested in the Steve Marsh situation.
Meanwhile on the other side of the world the European Union Commission has declared that honey which may contain just one grain of GM pollen will have to be labelled as derived from GM. German honeymakers are seeing this as an opportunity to rid their lands of GM crops, and to seek redress for loss of income from any resultant contamination.
Having enjoyed over a decade of transparent GM labelling, a healthy debate in the media, and the ability to declare areas, and countries, GM free and be allowed to uphold that choice, we can only envy the EU’s position in regard to protecting themselves and their livelihoods from invasive and unwanted GM crops.
If we want to see such success here we will have to maintain the pressure, show a united front and refuse any idea of lowering our standards.
Cheers,
Janet Grogan Jan60gro@yahoo.com |

Interview with Jason Fowler, Cook and Owner of 12 Mile Café in Broome
What makes an organic café different? Well 50 % of the menu had to have 100% organic ingredients. A limited supply of organic ingredients means the menu had to be flexible and adaptable to what is available. For example our Gado Gado Salad has a variety of steamed veggies with peanut satay sauce. If one veggie is not available, such as sweet potato, it can be substituted with another such as potato.
Do you find this challenging? Of course! It means we have to be more creative to achieve a 100% organic dish. One of our popular cakes is a Kaffir Lime Polenta Torte which traditionally uses lemons. The lemon supply stopped and at the same time we had a glut of Kaffir Limes so we substituted and created a delicious new torte. So it inspires creativity.
What’s taboo in the Café? Anything GM (the Greenpeace truefood guide is very useful when shopping and lets you know which brands to avoid), caged chicken and eggs. We try to think sustainable and local when sourcing ingredients and cleaning products.
What’s involved in the yearly audit? You have to provide evidence that the organic ingredients are traceable to their source. Cleaning products are examined and how they are used. A normal organic café (which doesn't have its own garden) may have problems separating organic from non organic ingredients in storage so cross contamination doesn't occur. Not such a problem for us as we use 90% organic ingredients.
Staff training is discussed to make sure staff is aware not to contaminate food with prohibited substances.
Lastly the menu is assessed to ensure compliance with 50% totally organic.
Is philosophy part of the audit? Yes. The auditor will question the owner on why they have chosen the organic path because they want to see that your basic philosophy is to be organic and sustainable. These questions are usually designed to bring out flaws or inconsistencies in management.
So tell us about 12 Mile Café. Our café is located on an organic/biodynamic farm 20km east of Broome. As far as sourcing ingredients we couldn't be more isolated! This means we rely heavily on our own produce. Our cooking philosophy is based on simplicity and letting the ingredients speak for themselves. We use lots of fresh herbs to give the dish flavour instead of drowning it in creamy/processed sauces or dressings.
Most of what we grow is of south East Asian origin and our food has a strong Malay/ Indonesian/ Thai/ Sri Lankan flavour but we aim to keep everyone happy by having European/Australian dishes as well. The organic lamb bolangaise is very popular.
What do you find most rewarding? When customers tell you that’s the best food they've had in months or the best sandwich ever! Showing people organic food is brilliant and that you don’t have to a 5 star chef to make it great!

Orchard Alert – Issue 1, Sept 2011 from the Agriculture Department
Thrips
The numbers of thrips found in stone fruit blossom in the Perth Hills and the Donnybrook regions have been low so far. However, this could change with the weather warming up and monitoring should continue until after shuck fall.
Identification and damage symptoms
Adult thrips are very small (1 to 2mm) winged insects. The two main species of thrips which can damage fruit crops during blossom are plague thrips and western flower thrips (WFT). Thrips species identification is difficult and should be left to the experts. Because control methods and damage are very different for these two species, and western flower thrips distribution is still spreading, it is important to know whether western flower thrips occurs in your orchard.
Plague thrips
Plague thrips are the main species present in orchards early in the season. Although they can breed in weeds and ground covers particularly capeweed, dock, sorrel and clover, their main source early in the season is native vegetation (wattles and gum trees). Their numbers in orchards are determined by what happens to their population in the bush.
On summer fruit, adults lay eggs into the flower ovary during blossom; emerged larvae feed under the calyx and can cause severe scarring on stone fruit.
On apples, heavy plague thrips infestation will cause flowers to abort resulting in lower fruit set.
Western flower thrips
Western flower thrips are an exotic species and primarily breed within the orchard on fruit trees and ground cover plants including weeds present in and/or around the orchard. Depending on the season, they are more likely to be a problem mid to late season when populations have had a chance to increase after winter.
On summer fruit, adults feeding on mature fruit will cause “silvering” in the period leading to harvest.
On apples, egg laying in the young fruitlets will result in a ‘pansy’ spot visible at harvest time.
Wind damage can cause symptoms very much like those attributed to thrips damage. Field sampling is needed to confirm the presence of thrips at blossom time.
Monitoring
Thrips monitoring should start at least two weeks before bloom and continue until harvest. Tapping is the preferred method for monitoring. Flowers, foliage and fruitlets should be sharply tapped over a white tray or container. Tap 4 flower clusters per trees over 25 trees (or 100 flower clusters). A 10xhand lens is required to see and count the thrips.
To collect thrips for identification, use a small paint brush dipped in a 70% solution of methylated spirit. Dab the insect with the paint brush and place it into a glass vial containing a small amount of the same solution. Take the specimens to your nearest DAFWA office for identification.
Management
Weed management can help reduce thrips population levels. Do not encourage host plants such as capeweed, dock, sorrel and clover to occupy the orchard floor. If you need to slash to suppress host plants, do so well before budbreak. Avoid disturbing the ground cover in the rows and around the orchard from immediately prior to budbreak until well after fruit set. Naturally occurring ladybirds, lacewings and predatory thrips may feed on thrips larvae but are unlikely to control infestations. However, their preservation is important so care should be taken.
Brown rot
In most areas, rainfall for the period August-September has been substantially higher than for the same period last year. The conditions so far this spring have been ideal for the development of brown rot on stone fruits. It is important to ensure stone fruit blossom is protected at all times.
San José scale
Orchardists in the Perth Hills have noticed large populations of San José scales while pruning their apple trees. San José scales are difficult to control and if left unmanaged can gradually weaken the tree, even causing premature death. Fruit marked by scales cannot be sold. San José scales are not tolerated in export fruit. Action must be taken when this pest is first noticed as populations can quickly explode making its control more difficult. Populations can build up during mild winters, similar to the one just experienced
Life cycle-Symptoms
A pest of both pome & stone fruits, San José scales overwinter mostly as immature adults protected by a hard grey wax coating. Their yellowish soft body can be seen with a hand lens if the protective cover is carefully removed. High numbers give the branches or twigs affected a scruffy grey appearance. On older trees, heavy infestations can match the colour and appearance of the bark.
In spring as the temperatures increase, these immature adults become either male or female. The males emerge as small winged insects. Females remain under the wax cover and do not move for their entire life.
Following mating, each female can give birth to up to 400 tiny live crawlers which are bright yellow and look like mites. These highly mobile crawlers leave their wax shelter and move to other parts in the tree or to other trees. Within 24 hours, they find a new feeding site and begin to suck sap. Constant feeding will weaken the trees which will appear water stressed. As they settle in and keep feeding, they develop a new hard wax cover. Initially white, this protective cap turns black later on and ultimately becomes grey.
The duration of the life cycle depends on temperature but is generally completed within 6 to 8 weeks. There can be 2 or 3 generations per year. If infestations are severe, young fruitlets can become misshapen and bumpy, particularly pears. These symptoms can be mistakenly attributed to boron deficiency or even apple dimpling bug.
Monitoring and management
San José scales favour dry weather and dusty conditions.
If damage was noticed on fruits during the previous harvest, trees should be carefully examined during winter and “hot spots” marked. Although the scales can only survive on live tissues, it is recommended to remove pruning’s from the orchard and to burn them if possible. The weakest point in the life cycle of the pest is the crawler stage when the pest is not protected by its wax coating. Monitoring the emergence of these crawlers in spring/summer will help
Proposed suspension of dimethoate
As part of its review of dimethoate, the Australian Pesticides and Veterinary Medicines Authority (APVMA) has completed the latest Residues and Dietary Risk Assessment (released 22 August 2011) and found that its use on many crops exceeds the health standard established in January this year.
The assessment concluded that some of the estimated exposures for consumers are above the health standard, reducing, but not breaching the margins of safety that are normally in place to protect consumers from short-term dietary risks.
The APVMA therefore proposes to suspend dimethoate products as an interim regulatory action while it completes further assessments on the chemical. This would effectively prohibit the use of dimethoate on certain horticultural crops, including for fruit fly treatments of many fruits and vegetables
