A huge part of the last 30+ years of my life has been helping people put their gardens together. The most important part of our customers success is choosing the right plants, planting them properly and looking after them as thy settle in. This coming Saturday the 17th at 10.30 I invite you to be part or a discussion that I call “the three P’s” … Plant Choice, Planting Procedure and Post Plant maintenance. Get these three things right and you are a long way towards having a enjoyable successful garden. I don’t expect that, at the end of this talk that you will have the same abilities that I’ve spent a life acquiring but I hope that those attending have the confidence to ask the right questions and a better knowledge to choose plants with confidence. |
Helping Pollinators in the Garden

 Helping Pollinators in the GardenWorld wide we are loosing our pollinators – our birds, bees
and other insects, and our nocturnal animals such as possums and bats. And without pollinators we don’t
eat. It sounds bizarre but it is
true, that without bees and other pollinators we die. It is a pretty simple
equation; everything that goes onto our dinner table relies on bees or other
pollinators. Without pollinators
our forests will de-evolve back to ferns, without pollination the high yield,
high-energy plants (monocotyledons & dicotyledons) will wither and die. The decline of larger animals – birds, bats and possums, is
mainly due to loss of habitat through land clearing. The decline in pollinating insects is due to the use of
insecticides, and the main killer for these small pollinators are systemic
insecticides*. All insecticides they are like bombs, they are
non-selective. And if a contact
insecticide acts like a bomb then systemic insecticides act like a nucellar
bomb – the residue from its application lasts a long time. Because of the insular nature of the Australian population
the first time most Aussies will notice there is a problem is when the
Supermarket shelves start to get bare.
Australians lead by our politicians will rightly blame farming
practices. But what our farmers do
is only part of the problem; the predominance of the use of systemic sprays
around our houses, on our gardens and in public places is growing. And there is evidence from overseas
that home gardeners over use systemic insecticides (there have been higher
concentrations measured in tissue samples from gardens than from farms). So the general population is also the
problem … and can also be part of the solution as explained in the next
paragraph.  What gets me is that we don’t have to use them. When we are healthy we are less likely
to get sick. And like us a healthy
vigorous plant has resistances to both fungal and insect attack. We keep our health up by having a
healthy well rounded diet, similarly keep the health and vigore of your plants
up by using a well rounded mineral based fertiliser. A healthy environment has many checks and balances. Remember that insecticides are like
bombs; they don’t just target bad insects. Like a healthy environment a healthy garden that has never
or rarely had an insecticide used in it will have a good number of predatory
insects (good guys) and insect eating birds to keep the plant eating insects in
check. It is to easy, and to
simplistic, to reach for the can of insecticide every time we see an
insect. There is always an underlying problem or weakness when there
is damaging insect attack, and using insecticides will further weaken the
balance within the garden environment.
So instead of seeing insect attack as a problem, look at the damage as a
symptom; it is that the plants are under stress that has led to them being weak
enough to succumb to insect attack.
Instead of directly targeting the insects prune the damaged foliage off
and give the plant a feed of a well balanced mineral based fertiliser. I run a nursery that sells ornamental Australian native
plants. I can’t sell plants that
have damaged leaves or stems. Yet
it has been over six months (warm months at that) since we have used an
insecticide. I have been
controlling insect damage to my plants by keeping the vigore of my plants up
through creating and using a superior potting media, selecting and using the
correct amount of fertiliser and, if there are problem insects damaging my
plants, using vegetable oils**. In
my experience, vegetable oils work as a knockdown for all soft bodied insects
and as a deterrent for hard bodied insects. I also suspect that it acts as a barrier to fungal
infection. I know that I will have
to resort to insecticides at some stage but its use will be targeted and for a
very short period of time insuring that the numbers of predatory insects are
kept up. So help your environment, improve the health of your garden,
be a friend to a bee:
And year by year the bird a bee population will increase and
your fruit bearing plants will provide more food as the balance within your
garden and local environment improves. If enough of us turn away from our dependence on
insecticides and use products that improve the strength of the plants within
our gardens them Gardens Supply Centres will stop stocking them and promote
products that will help improve the garden environment. And by doing so lessen the use of
insecticides as more people become aware of better ways to protect their
gardens. And as more people become
aware of the potential problems of insecticide use the governments will respond
furthering the discussion … at lest that is my hope. Nick Hansa Fairhill Native Plants & Botanic Gardens * A systemic insecticide is a poison that is taken up by the
plants and distributed to every part of the plant, including the flowers and
fruit. Traditionally systemic
insecticides are sprayed onto the foliage of the plant but they come in forms
that are delivered via the root system.
Systemic sprays can be persistent within the plant for up to four weeks,
when applied via the soil it can be persistent for years. There are many different brands but it
is safe to assume that all for them have neonicotinoids as the active
ingredient which, in simplistic terms, is a nerve agent. **There are many recipes for vegetable oil sprays and you
can buy them pre-mixed. The recipe
that I use is: Canola Oil mixed
with enough dishwashing liquid to act as an emulsifier (approx. 1 cup of oil to
1 tablespoon of detergent). This
is mix at a rate of 10-15ml. to 1 litre of water. Bibliography |
Birdwatching at Fairhill

On the last Wednesday day of every month at 8.00am during
winter (7.00am starting August) the Wednesday Day Club spend and hour wondering
through Fairhill Botanic Gardens enjoying the huge diversity of bird life that
the gardens have attracted before retiring to have a cuppa, talk about their
sightings and a chat. On most
outings they identify over 60 different types of birds with the highest number
being 85 seen and three heard, that’s a huge diversity in a 10 acre
garden. They have listed over 150
species of birds over the past years. There is a consensus among the Wednesday Day club members
that the best bird watching any where is in the Fairhill Botanic Gardens which
is pleasing in many ways but in a lot of ways it is very concerning as is
indicates a lack of bird habitat else ware. In 1974 Fairhill Botanic Gardens was a dairy farm, not one
tree or shrub on the place. It has
been interesting to watch the changes in the bird population as the gardens
evolved. Before any of the trees
and shrubs the bird life consisted of open field bird, the Butcherbirds,
Magpies, Peewees and the odd Kookaburra.
As the quicker flowering garden beds started to provide
shelter the Honeyeaters started to arrive followed by finches and wrens as more
seed producing plants started to produce. Evolving further, the rainforest gardens started to close in
and rainforest birds such as Emerald Doves, Catbirds and Whipbirds took up
residency. During this stage the open field birds declined and the
gardens went through a period when they disappeared altogether. But recently they have started to come
back as the trees started to provide a habitat for them. There are Noisy Miners on the list of sighted birds; they
are occasionally seen in the open paddocks on either side but never in the
gardens. This is because the Noisy
Miner is an attack bird. It needs
open lines of sight so that it can dominate all other birds. And because the gardens don’t provide
that, the Noisy Miners don’t feel comfortable and stay away. At the last gathering of the Wednesday Clubbers there was a
discussion about the decline of bird life. The consensus is that there is a lack of corridors (one
comment was “that a bird can no longer travel from Brisbane to the Sunshine
Coast any more”) but also the lack of habitat in private gardens. Fairhill Botanic Gardens is a great
example of how a bird friendly garden can be created. And it does not need to be 10 acres, there a some fantastic
examples of small backyards providing great support for the bird population, we
just need more of them. The morning of the last Wednesday of the month is a really
enjoyable time in the gardens and the members of the Wednesday Day Club invite
all who has the time to join in.
There are no membership fees, just role up to Fairhill Botanic Gardens
and join in. The next gathering is on Wednesday the 26 of
June; look forward to seeing you then. |
Platypus Sighting

It’s been confirmed! Three weeks ago I sighted a platypus on the Fairhill dam. I was stoked of course but everyone that I spoke to bragging about the sighting doubted me with comments like; “are you sure”, “really” followed by mumbling something like “yea right Nick” and other remarks that are probably better left unsaid. On the last Wednesday of every month there is a bird watching group (called the “Wednesday Club”) come to the gardens to see what birds they can find. Last Wednesday as well as seeing 61 different birds they also sighted the fabled platypus. And better than that – some in the group recon they are two platypi. They were thrilled but a bit perplexed at my comment of “that’s confirmed”, I was relieved (it wasn’t my imagination). Fairhill Botanic Gardens is a haven of sights and sounds and the addition of either one platypus or, even better, two platypi … well it makes it even better. PS If I manage to get a photo (with platypi that can be a bit of an ask) I'll past ot this page. |

The sun is out, Grevillea and Banksia are flowering, the
gardens are looking a treat and the birds are loving it. On the last Wednesday of each month a group of bird watches
(called “The Wednesday Club”) come to the nursery and gardens to see what birds
they can find, have a cup of tea or coffee and a chat. Each month they typically see and hear
50 to 60 different birds. Last
Wednesday they saw 63 birds and heard a further 20 different birds, 83 species
of birds in one morning - WOW!! Everyone is welcome to come along and join in with The
Wednesday Club, so if can make it at 7.00am on the last Wednesday feel free to
join in. If there are any topics that you would like to find out more about send us your ideas and we’ll see if we can get something together. |
Autumn Is the Time to Plant

Autumn is the time to plant!! As I’m writing this blog I can already hear the mumblings
“here we go, a salesman trying to drum up some business”. Most people think that spring is the best time to plant but
its not. There is no right or
wrong time to plant in the warm temperate, subtropical and tropical areas of
Australia but the best time to plant is autumn as I’ll show you below. Compare the conditions in spring, when most gardeners plant
and autumn when there is not much planting done. In spring the soil is cold and dry (cold because winter has
just finished and dry because late winter and spring tends to be the driest
part of the year) and the ambient temperature is rising, often quite
radically. All of this makes it
quite stressful for the plants being planted (and those planting them). In autumn conditions are much, much more favourable, the
soil is warm and moist (warm because it has had all of spring and summer to
heat up and moist because most of our rain falls in late summer and early
autumn) and the ambient temperature is falling slowly. All of these conditions a make for an
almost stress free transaction from pot to ground, both for the plants and
those planting them. The other
advantage of autumn planting is that you don’t need to be consistently
watering. Often all you need to do
is water the plants in and keep an eye on them, only giving the occasional deep
watering. If you are in a frost zone it will be important to protect
newly planted plants from frost for the first year. I resent being called a salesman, I’m a “plantsman”, have
been for most of my life and yes I am trying to drum up sales, but only because
this is when my customers and I, those that have taken my advice, get the best
results and pest satisfaction from their gardening. |
