Despite this week of
real summer heat, the previous months of cold, wet and windy weather means that
many of us are having trouble with our “summer” vegetables. I have
self-sown miners’ lettuce, a cold season, salad green, coming up in my garden
now when it normally comes up in autumn. There is not much we can do about the
weather so I have decided to move on to attending more to the soil and to
sowing winter vegetables.
Observe and Interact
This is the first principle of Permaculture. I have observed
the weather and my garden and decided to take some action to work with, rather
than against, nature.
Here is what I am doing to areas of my food garden that I
have decided are never going to produce a worthwhile crop this summer. It is a
ruthless decision but a good one. Excellent vegetables are available from our
wonderful, organic, local market gardeners and small green grocers and I will
still hope that my tomatoes will produce.
1.
I push over all the plants so they lie in the
one direction, flat on the ground. Then, using a sharp spade, I chop it all up
and leave it on the ground, weeds and all (as long as they are not seeding).
2.
I then sprinkle lime plus ash from the fire over
as most of our Tasmanian soils are acidic and most of the winter veg we grow
like alkaline soil. Ash also adds potassium and trace elements but has no
calcium. Lime has calcium.
3.
If you have homemade compost you can add it
next. If not, then do not worry.
4.
The next layer, when broken down, adds organic
matter to a thin or hard soil, and is lucerne hay (Available locally. See her
advert. in this paper). It is expensive but full of nutrients and you don’t
need a thick layer. Pea stray would be great too. If you really don’t want to
buy these, then newspaper could substitute, especially if your soil is already
lovely and friable. Wet the layers of paper well as you go.
5.
Then, separated from the lime by the lucerne or
paper, I add mushroom compost or cow manure or pelletised chicken manure or
sheep manure. (Manure should not be mixed with the lime or nutrient take up is
affected. By the time the paper / lucerne breaks down, the lime has dissolved
into the soil).
6.
I will then add a thin layer of mulch such as
ordinary straw. This keeps the soil life from the extremes of temperature as
they break down the layers below.
7.
Water well as you assemble the layers. That way
any future rain will penetrate and start feeding your soil.
8.
Plant out your seedlings into this in autumn.
What to sow now and why
At 43 degrees south the days shorten and the light softens
to such as extent in winter that is seriously affects the growth of plants. Think
of the leaves of, for example, kale, as solar panels. With short days and the
sun low in the sky each leaf needs to be twice as big in winter as in summer to
catch the same amount of sun to power the plant. To achieve this growth by the
end of autumn we need to sow these big plants now!! Once we get to mid-May food
plants need to be full size so we can begin to harvest them through winter.
Moreover, we need to sow twice as many now as we would
coming into spring when days are lengthening, so that we can allow the plants
extra time to regrow after each harvest.
Getting the soil to its optimum condition for this time by
working on it now will ensure your winter vegetables flourish. There is nothing
more beautiful than picking vegetables that are dusted with frost, when you are
rugged up in boots and scarf, fingers cold and the light sparkling on every
leaf as the ice melts.
So, in trays in a sheltered spot I am sowing all my
favourite soup, casserole and roasting vegetables, to eat by the fire in winter
while I sip my homemade raspberry ratafia, blackcurrant cassis and Tas.
pepperberries in vodka!
Fire and the garden
The recent reminders in the news about the Dunalley fires need
action. Is there anything we can do to help protect our homes from fire? Most
fires are not as devastating as the Dunalley fires and we can do some things to
help reduce the flammability of our surroundings. Lush, deciduous trees and
shrubs can replace those closest to the house, which contain oils, such as gum
trees and even rosemary. There are excellent flammability lists on the Fire Tas
website: www.fire.tas.gov.au/publications/1709%20Brochure.pdf
Watering
Almost everyone I speak to overwaters everything!! In the
Tasmanian climate only minimal watering is required, unless extremely hot days
are forecast.
I stick my finger into the soil, up to the second knuckle
(first knuckle for pots). If the very tip of the finger feels dampness, I do
not water, unless I am expecting extreme heat.
This encourages the roots to seek water down deep, where the
soil moisture and temperature levels are more constant. If a plant develops
shallow roots, it struggles to manage on a hot day as the soil around its roots
becomes hot and dry very quickly and appears to need more water. Train your
plants well and they will be happy, like your dogs and children!
