An Ounce Of Prevention



Being in the depth of winter here in Tasmania with the temperature regularly dropping into minus temperatures overnight now our first topic discussed at the Living Better meet-up was wool; it's use, care and protection. 
Coincidently this week, 4Corners aired a particularly damning expose of the exploitation of clothing factory workers. To say that these workers paid less than $3 per day in unsafe factories with no entitlements, protection etc is to spouse the usual blah, blah rhetoric. But to SEE their maimed and missing limbs and hear how a mother sees her son just once a year etc etc....
This is big clothing companies that retail in our countries squeezing the tightest dollar from the manufacturers. I am taking some responsibility for this too. Recently I have bought insanely cheap knitwear and though I marvelled and mused "how can they make it for the price?" that was as far as my thoughts went. In this country as recession has hit, we have congratulated ourselves staying afloat, keeping fed, staying warm....but clearly at the expense of poorer countries. 
Please, I urge you to watch this episode and report from 4 Corners called

The book in the photo above as you can see by the cover is a collection of war time brochures that though outdated in some of the energy information, still has valuable and timely household wisdom for today. A lot of the literature was about making clothing last. Our group discussed how in today's society little thought is given to the preservation or care of clothing. It is bought so cheaply and usually quality is compromised. Households are more inclined to throw clothing into machines and wear them less than a year and casually toss them out. Like the "Slow Food" movement principles, we can apply this also to our goods we use and wear. For instance, think about kitchen cabinetry. When you add up the time the timber took to grow, the miles that the product, raw and dressed travelled, the hours that it passed from hand to hand as it was crafted from tree to cabinet, it becomes mind boggling when one considers how cavalier people can be gutting their kitchens for a new one because it is not cosmetically fashionable enough.


Not so for Kylie over at lucy violet vintage, check out her story here about saving a Tasmanian Oak kitchen on the other side of Australia....but I digress a little.
Back to wool. Same applies. From the farmer to the shearer to the textile worker, literally miles and miles and lots of dollars but what IF we stopped for a moment and consciously thought about our purchases and cared for our things with the respect they deserved. 
Wool is a champion fibre. It is insulating and used in housing and garments. It can be spun from the finest of threads to the thick textiles and even felted. It is soil and stain resistant. It is fire retardant. 
I have woollen garments in my wardrobe typically older than 20 years. My oldest garment would be my grey scarf that my mother used to wear in 1973. That's 40 years old! Even older is the dress that my father knit for my grandmother, tucked away in a trunk here safely.


This is typical moth damage.
Woollen garments need not be washed every single wear as they are soil resistant. A mark needs only spot treatment like a sponge. After wear simply air before folding and putting away. Perhaps there has been a spot here and a moth has certainly found it. 


At the meet-up last night we discussed some simple ingredients from our garden and local area that can be used to deter moths and silverfish in cupboards. 
You may recall posts recently about our trip to the west coast. While there I picked up a couple of bags of Huon pine shavings, wonderful for the hen house and in the nesting boxes acts as a natural insect deterrent. It smells divine too. If you don't have access to Huon Pine then Cedar chips are commonly used in such a sachet. I acquired absithe artemesia plant from Killiecrankie Farm, commonly it is known as Wormwood and another wonderful pest deterrent and good for planting near the fowl yard. In the later part of summer I harvested and dried the leaves easily for use in wardrobe sachets. The lavender was also cut and dried upside down in the summer. Not only does it smell good but it is also an insect deterrent. Lastly from the pantry we added cloves which also has anti-mould properties. 
People have used ingredients like these for centuries. There are no hard and fast rules, just make sure the ingredients are dry and that they have insect repellent properties. You can also add essential oils if you wish to or other fragrant herbs as you prefer. 


You can simply cut a square of fine lawn or muslin and place a small pile of the ingredients in the centre then gather the fabric and tie off with a piece of string or ribbon. Recycle those small gauze drawstring sachets you sometimes get or stitch a shape like the heart above (here for more ideas and also here) and stuff with the ingredients and some wadding and sew closed. As simple or as pretty as you like. This is a great project to do with children and they make lovely presents at Christmas or for teachers.
And that was just the FIRST topic we discussed but that's enough for now, more tomorrow.....

Before You Drop That Bomb...


Some green beans climbing the federation fencing wire. Lush, happy and producing loads of beans.
Let's have a closer look though....


Does the sight of this cause you to gasp and quickly head for the pesticide? 
It certainly does for most people. Even organic growers reach for pyrethrum (because it's safe and natural right?) or some other concoction of rhubarb leaves or tobacco. 
WAIT, can I ask you to spend 10 minutes before you do and really look at the plant and ask yourself a couple of questions first.


There is some leaf damage but there are also more flowers and plenty of beans. The vines seem to be in good health. Healthy plants should tolerate a reasonable amount of attack from pests.
Don't reach for poison just yet.


There are a couple of dead cabbage moths (bottom left) within but I think they have sought shelter here. I bet they have laid their eggs elsewhere. I can't see their eggs hanging from the underside of the leaves or their chubby bright green caterpillars munching away.


I've searched and searched but can't give you a definitive identification of this common garden moth we get here in Tasmania. It is sheltering from the mizzling rain. The moth itself is not a problem but the larvae that hatch are leaf eaters. During my quick inspection I only see two so they are clearly not in outrageous numbers yet.


Here is a green shield bug. Shield bugs make up a large common category and are sap suckers. In great numbers these could definitely ruin your plant. They are easy to spot because they don't particularly hide from predators. They do tend to be a colour that blends with their surroundings but they also have stink glands that secret a foul smelling liquid, hence their other common name of stink bugs. Because of their harder shell, pyrethrum is usually not effective anyway. So hold that spray!
KEEP LOOKING....


Ahh, the nymph stage (young before adult stage) of the above green shield bug. I am no entomologist but I suspect the colourings are for warning or "foxing" as it probably hasn't developed it's stink glands yet.



This is significant though. I can see six nymph shield bugs in a small space. Numbers are multiplying and definitely could do significant damage but experience has shown me that the plant will take a bit of sap sucking.


Some baby spiders show me that other predators are in the area.
Consider first and remember that spraying a control substance will also kill the predators that are helping you with your problem. Within this vine is probably small frogs and stick insects who also rely on bugs for food.


So standing back and weighing it all up....
The plant has been producing well and I have been picking beans for about six weeks. yes there are some holes and webbing leaf damage but the beans are tender and juicy. Reasonably I can expect another few weeks of picking and I weigh that up with wading in and killing the bugs. What would I gain? Another week or two of cropping? By then the beans are getting tired any way.
The shield bugs perhaps look like they are increasing but natural predation could take care of that within the next week. Given that pyrethrum isn't effective there is no point spraying. My preferred method of control is manual in most cases anyway. In this instance you would use a small brush to move them into a jar or a pair of forceps because remember, they secrete smelly stuff and you don't want that on your hands.

From my experience in the garden, I find the key is to keep things in balance and everything will cycle and take care of itself. 
You definitely DO NOT want to eradicate any one thing.
 Just because it is a pest doesn't mean that it doesn't have a vital part to play. Everything is reliant on something else. It's all part of the cycle  or the chain. Think of yourself as the custodian of the garden rather than the controller. Your job is to aid and assist not to seek and destroy.
I haven't used any sprays in my garden, organic or otherwise in at least 20 years. 
Spend a little time and weigh it all up, including the consequences of wiping out not one but several species. Could you be in fact doing even more harm than a few chewed leaves?
