DENDROBIUMS Part 3

Cultivation and care

If you been listening to the series on dendrobium orchids you might now be wondering how best to look after them? 
You might even be asking do I need a greenhouse or shadehouse like Adrian has for his 200 or so orchids, or can you grow just one or two without too much fuss somewhere in the garden?

Dendrobium_nobile_%2528BG_Zurich%2529-04.jpg

Let’s find out.. 
I'm talking with Adrian O’Malley, native plant and orchid expert. 
 
The three most important things for care of your dendrobiums are location, watering and fertilising. 
Adrian’s tips is let them completely dry out in winter, but if temperatures are in the high 40’s, you may need to mist them several times a day. 

If they look pinched they need watering.

  • Fertilising
Adrian has an inline fertilising system which is attached to a hose but before the tap. He then places a rock mineral fertiliser in that inline system which leaches a very small amount into the water each time he waters the orchids.
Adrian also recommends using two types of additional fertilisers depending on the time of year.
Fertilisers high in potash to promote spring flowering, and fertilisers high in nitrogen to promote growth.
Tip: Add a handful of dolomite lime over the bark mix every couple of years to counteract the acidity of the media as it breaks down.

Real World Gardener Hybrid Dendrobium Orchids of the Week

October 8th, 2020

Dendrobium sp. episode 2

Dendrobium hybrids

Australia has 50 native species of dendrobiums and dockrillias and most of these grow mainly somewhere along the east coast of Australia. 
The ones that grow in Qld, in quite warm temperature to tropical areas, don’t grow so well further south and one might need a greenhouse to grow some of these.

D_Hilda%2BPoxon.jpg

But those that originate in Victoria or NSW don’t do so well in the tropics. 
This is where hybrid dendrobiums of these native orchids come in 
Let’s find out.. 
I'm talking to native plant expert and orchidophile, Adrian O’Malley 

Hybrid dendrobiums are numerous and as an example can be crosses of Dendrobium speciosum and Dendrobium kingianum. 
This particular cross gives you Dendrobium x delicatum which can have either with or pink flowers and even perfume. 
A famous one that Adrian mentioned is Dendrobium Hilda Poxon (pictured above).
This is a cross between Dendrobium speciosum x Dendrobium tetragonum

Real World Gardener Rock Thryptomene in Plant of the Week

September 27th, 2020

PLANT OF THE WEEK

Thryptomene sp and Thryptomene saxicola F.C.Payne

There are some plants that can be forgiven for not doing much for most of the year, then, when they come into flower, they become the star of the garden.
In a way, they behave like a spring or summer bulbs, because they’re practically invisible until they pop out and flower their heads off.

Thryptomene.jpg

So what is this Thryptomene which I have been alluding to? 
Let’s find out more… 
I'm talking with Adrian O’Mally, qualified horticulturist and native plant expert.
PLAY:Thryptomene NEW_26th August 2020 

Rock thryptomene is as close to a common name as you'll get for this plant.
Growth is as for a sub-shrub 0.75 – 1.5m tall by 1 – 1.5 wide.

  • Adrian came across seven thryptomene planted along a bank with a south-east aspect.
  • They had grown leggy so to keep your shrub bushy, keep up the formative pruning in the early stages.
  • Doing this you will able to keep the shrub to 60cm in height.
Thryptomene is evergreen with a slightly weeping habit and  aromatic small leaves are small.
You may find it as a filler in bouquets because the tiny 5-petalled flowers blend well with larger flowers of any kind.
Thryptomene saxicola (pictured below)
 
Thryptomene_saxicola-flowers.jpg
Thryptomene paynei, then newly introduced to New Zealand was "raised by FC Payne of Adelaide".
F.C. Payne was the owner of "The Sanctuary" plant nursery in Ashton, in the Adelaide hills of South Australia who promoted the use of Australian native plants in local gardens.
By 1967 the cultivar had become a "garden favourite" in Australia and was featured in a gardening guide for native plants in The Australian Women's Weekly.

Bird and insect attracting plants always make a lovely addition to your garden. 
Look out for the different cultivars of thryptomene in your nursery or big box store this spring, because there won’t be many, and they’ll be snapped up quick smart. If you have any questions about anything gardening, why not email us realworldgardener@gmail.com
 

Real World Gardener Creating Habitat for Native Bees in The Good Earth

August 26th, 2020

THE GOOD EARTH

Building Habitat for Native Bees

This year, gardening has been taken up by many people who have never gardened before.
But that’s not all, worm farming, keeping chickens and bee-keeping have become more popular because people are spending more time at home. 
You probably know there are honey bees and Australian native bees. 
But which type of bees pollinate your crops better or is there no difference?
Let’s find out.. 
I'm talking with Margaret Mossakowska of www.mosshouse.com.au 

Margaret suggests build habitat for the native bees because they are so much better at pollinating your flowers, in particular veggies in the tomato family, than honey bees. 

Blue%2Bbanded%2Bbee.jpg

 

  • Building native bee habitat can be bricks made from clay, or wood and other materials.

Margaret's Clay Bricks Recipe

Mix clay with water then 2 or 3 parts of sand.
Margaret then pours the mix into moulds. One litre milk containers say from rice milk.
When dry she drills various size holes into these 'clay' bricks and places them strategically around the garden.
  • For 'blue banded bees,'  or even 'teddy bear bees,' drill holes 6mm in size and 6cm deep. The bees will excavate the holes further.
  • Bees will also next in bricks where the mortar has worn out. 

Bee%2Bhabitat.jpg

Most native bees are dormant or die during the Australian winters.

Flower are important from spring onwards.
Plant flowering trees with small flowers such as melaleucas or paperbarks.
  • Borage is also an excellent plant for bees because it has a high percentage of protein and sugar in the pollen and nectar.

    1-1-1-Borage-Flowers-for-blog.jpg
  • Perennial basil is also fantastic for not only attracting bees but hover flies and other beneficial insects to the garden.
  • Why not also let some parsley or coriander go to seed.
  • Provide some water for the bees-not deep, and include some pebbles so the bees don't drown. Plant saucers are ideal for this purpose.

Common Name:Golden Guinea Flower: Snake vine

Latin Name: Hibbertia scandens
Family: Dilleniaceae
Etymology: Hibbertia...after George Hibbert, a patron of botany; scandens.... "climbing", because of the climbing habit of the species.

Hibbertia scandens
What else?
Let’s find out…

That was Adrian O’Malley, qualified horticulturist and native plant expert.
Hibbertias are sometimes called Guinea Flowers because the flower shape and colour looks like the ancient Golden Guinea coin.
When Adrian has seen it in the bush, it's mostly in open forest or gullies. 

The flowers shape and colour is a dead give-away for the hibbertia species.
The "snakes" are the tendrils that twine themselves together and climb up.
Perfect specimen for sloping sites where it can scramble freely.

Real World Gardener Australian Mint Bush in Plant of the Week

June 26th, 2020

PLANT OF THE WEEK

Prostanthera lasianthos and other species. Australian Mint Bush

It smells like mint but is it? The leaves are round or sometimes oval or even pointy. 

It’s even in the same family as common mint: Lamiaceae
Australia does have a wide variety of endemic mint bushes.

There are 90 species all of which originate somewhere in the bush,  but how well does it do in your garden? 
I'm talking with Adrian O’Malley, qualified horticulturist and native plant expert. 

Prostanthera comes from the Greek for an appendage because inside the flowers are small spur-like appendages on the anthers. 
These minty plants are bushy, evergreen shrubs, usually with strongly aromatic leaves.

Heaps of purple flowers covers the soft leaves all through spring and early summer, attracting butterflies and small insect-eating birds. 

did you know?

  • Mint bushes often wilt when they badly need a water, particular in the summer months.Because of this, they are excellent "indicator" plant for the rest of the garden.
 
Prostanthera lasianthos


Some of the varieties available are:

Prostanthera lasianthos is quick growing and in good conditions may reach 8-10 metres. Tolerates heavy shade as well as full sun.

  1. ovalifoliahas very aromatic foliage. Quick growing and spectacular in flower. Prune back by about one third to keep that bushy habit. Suitable for full sun or semi shade.
  2. rotundifolia- Very aromatic foliage. Quick growing and spectacular in flower. Needs pruning back by about one third every year to keep a bushy habit. Can grow in sun or semi shade. Prostanthera_lasianthos_flowers.jpg

The leaves are round while growing as a compact shrub that reaches a height of one and a half metres in our garden.  The flowers are over one centimetre wide and mauve to purple

Plant it along a pathway so you get the benefit of brushing past the fragrant leaves. 

Good pot plant also. Feed with a good native fertiliser, watering in afterwards to avoid leaf or root burn.

Real World Gardener Creating Edible Gardens part 3 in Design Elements

June 11th, 2020

DESIGN ELEMENTS

Edible Gardens Series Part 3

Part 3 is selecting and buying the seeds and plants.
Probably the most enjoyable part of the edible garden process.
So which seeds or plants and where to buy and what about crop rotation?
Let’s find out…
I'm talking with Glenice Buck, landscape designer and consulting arborist. 

You don't have to go to a store, because every type of vegetable is available online, either as a seed, or seedlings.
You can buy advanced seedlings as an example, from a mail order company in Gippsland, Victoria if it‘s getting a bit late to sow or plant your winter crop. www.diggers.com.au 
They call them speedings, because they’re at least a month ahead of where you would be if you started them from seeds.

diggers%2Bspeeding%2Bcollection.jpg
Diggers seeds speeding collection

Seeds are of course much cheaper but they could be 6-8 weeks behind seedlings, especially cabbages and other brassicas which are quite slow growing.

The other issue if you plant out winter crops too late, so that when they're maturing, the season is too warm. Warm weather can bring with it more fungal problems and a horde of insects to infest your crop.

  • Crop Rotation Is Important

Crop rotation is important of course so that you don't have a build of pests of diseases with a particular crop.

If you understand which group the vegetable your growing belongs to, then you can understand what to plant next once a certain crop is finished. Never grow the same crop more than once in the same bed.

Fabacea or Legume family: peas, beans

Asteraceae or Daisy Family: Leafy crops: spinach, lettuces, chicory.

Solanaceae or Potato family:-tomatoes, cucumbers, eggplant, capsicum

Apiaceae or Carrot family-carrots, parsnip, parsley, dill, celeriac

Brassicaceae or Cabbage family: broccoli, cabbage, brussel sprouts, cauliflower, radish

Amaranthaceae or beetroot family: beetroot, spinach, swiss chard

Cucurbitaceae or Marrow family-cucumber, zucchini, squash, marrow, melon
