Personally I’m a fan of scented plants whether it’s the flowers or the leaves.
I just love to inhale their perfume either by sniffing the flowers or touching the leaves.

This next plant, the rose geranium, is not just your ordinary scented geranium because of its many uses.

Sure you can get by just inhaling the perfume after crushing the leaves but why not think about it’s culinary uses, especially in festive drinks. 

First let's talk about the plant.

Rose geraniums are quick growing especially in the warmest months of the year.

Expect this to be a small bush of 1-2-1.5meters with leaves that are soft to the touch, slight hairy and deeply incised as pictured on the right. 

Rose geraniums grow best in full sun but can tolerate part shade. Also frost and drought tolerant.

Keep pruning the leaves to make your rose geranium plant into a tidy compact form, otherwise it will tend to flop over and sprawl a bit.

Don't throw away the cuttings or prunings as all geraniums root easily and quickly. 

Just cut a piece or stem of about 5cm long, first removing the bottom two-thirds of leaves. Pop this piece into seed raising mix in a small pot or you can even place cuttings in water.

Rooted cuttings soon grow into plants that make great gifts to give to friends.

But don't waste those leaves, because what better way to use them, than making a rose geranium syrup to pour over ice-cream or a rose geranium spritzer.

Start off with making a rose geranium syrup.

All you need is 1 cup of sugar, 1 cup of water and 1 cup of chopped rose geranium leaves.

Slime Moulds part 2

The podcast continues with the topic of slime mould but particularly, about the slime mould called phytophthora. 

Did you prick up your ears?
Yep, that’s the root rot known as phytophthora which gardeners dread.

Gardeners are often told that phytophthera, in particular Phytophthera cinnamomi,  is a fungi but it's actually a water mould. You may have even heard it called 'root rot.'

• Phytophora is a particular slime mould that belongs to a group or Phyllum called Oomycota 
• This group are moulds that can only move in water columns.

Phytophthora cinnamomi lives in the soil and in plant tissues, 

During drought or prolonged dry periods , the organisms become dormant chlamydospores which is just a resting spore of Ascomycota. 

When environmental conditions are suitable, the chlamydospores germinate, producing mycelia (or hyphae) and sporangia. 

The sporangia ripen and release zoospores, which infect plant roots by entering the root behind the root tip. 

This organism is very resistant to most chemicals that gardeners can throw at it and doesn't die with soil disturbance..

Dieback of branches of whole shrubs or trees is often seen in the Australian bush.

Should you ever see branch dieback in your trees or shrubs or stem dieback in your tomatoes, it just may be due to a problem called root rot that is actually a slime mould. 

The best way Botanic gardens have dealt with it is by fencing off affected beds within the gardens so horticulturists and the public don't transfer the spores around the the gardens or indeed, back home to their own gardens.

Drainage was also improved in garden beds so that the organism wasn't able to stay 'live' or active.

Compost is also added to soil to improve the soil so the microorganisms can combat this slime mould.

Let’s find out more by listening to the podcast.

I'm talking with Steve McGrane, horticulturist and agriculturist.

So know you know the facts and myths about Phytophthera and how to deal with it in your garden.

Slime Mould: What Is It? 

Part 1

What do the words slime mould conjure up in your imagination?
Is it that black stuff growing in the grout and on the tiles in your bathroom?
Or is it that green stuff on your paths on the south side of the house?
You may be surprised to find that it’s neither one of those so where is it lurking?
There are a lot of other moulds that live in the garden some of which are very useful.

Wolf Milk Slime mould

Slime moulds are in the kingdom:Protista.

Did you know that slime moulds have a life cycle, and when you are able to observe them, is only part of their lifecycle?

They're usually brightly coloured -reds, vivid greens, yellow and purple. 

They can grow on grass, logs and pretty much anywhere where the environment is conducive.

Slime moulds are not very well known in Australia, but Tasmania has around 100 species of slime moulds one of which is called 'dog vomit.' 

Slime moulds are highly useful in that they break down materials, 80% of which is made available to plants.

GRAFTING TECHNIQUES Part 2

Approach grafting is an alternative method for citrus.

In part 1 of grafting techniques Margaret Mossakowska and I talked about how growing from a tree such as an orange or lemon from seed isn’t all that successful unless you graft it onto hardy rootstock.

In this segment, we refresh some of those points and take you onto more grafting techniques.

There are many types of grafting that are available to be used, some more complex or more exacting than others.

My Take On Grafting

Cleft grafting I find is quite straight forward and easy to get right. 

I've tried grafting Camellia reticulata scions onto Camellia sasanqua rootstock with a 100% success rate.  Camellia reticulata has huge flowers, a feature I wanted growing in my garden.

Camellia 'Red Crystal' is a cross between C.reticulata ‘Crimson Robe’ and C. japonica ‘Wildfire,’ however, both are slow growing. and don't grow so fast in temperate Sydney.

I find this is a faster alternative, plus Camellia sasanquas are very hardy and less prone to root rot.

Camellia 'Red Crystal'

• Grafting citrus is essential in Australia because the table citrus that we love to eat are not native to Australia, and so are prone to many diseases. 

The grafted union in most cases needs to be above the ground. There is one exception and that is with lilacs(Syringia vulgaris.). Lilacs tend to sucker if grown on their own rootstock so they are grafted onto privet rootstocks.

Things to Watch Out For.

Grafting Techniques part 1 & 2

Lemon tree

• Switch to grafting methods.

Practice makes perfect and I would recommend wearing gloves before attempting to do any type of grafting.

Grafting is a swag of techniques that involves having a root stock that is happily growing in the ground or in a pot, whose upper part you will cut off completely.

• Margaret describes cleft grafting where the scion's base is cut as a 'V' and inserted into the same length slit into the rootstock. The cambium (green wood) of each must be aligned.

TIP:If you’ve never tried grafting, make sure you get the right tools before you start.

SMALL SPACE GARDENING-COURTYARD STYLE

Modern day gardens are much smaller than they used to be.

Be inspired

• Corinne has managed to squeeze in over 200 plants into a small paved courtyard-that doesn't even include duplicates of plants.
• A good start is with recycling crates from your local council, to give you an idea of what works for you. Alternatively, plant into lots of containers that can be moved around to follow the sun.Then venture into raised garden beds.

Soil prep is key for Corinne.

• Grow cucumbers on a lattice made of string.

   The raised garden beds are made up with homemade compost, worm castings and bought in compost and other organic material.

Think of vertical spaces

• Think about growing vines like cucumbers and zucchinis and even nasturtiums, vertically.
  

PLANT OF THE WEEK Number 2

Scientific Name: Atriplex nummularia

Possibly, listeners would be familiar with the term ‘old man saltbush’ or even have seen this plant growing somewhere.

But I daresay, you would not have heards that parts of this plant are considered bush tucker.
There are many bush tucker plants that are not that well known and this is another one of them.

• The Department of Primary Industries NSW recommends the following for farmland. 

"Shrubs are grown in hedgerows as block or alley plantings across the farm to provide high-protein green feed during periods of feed shortage."

"Shrubs are grown in hedgerows as block or alley plantings across the farm to provide high-protein green feed during periods of feed shortage.Not recommended for areas with less than 300 mm average annual rainfall, or more than 600 mm average annual rainfall." 

In the home garden, if you’re first planting out old man saltbush, don’t expect it to survive without any water at the start. After the first warm season, then it’s good to go on just what falls out of the sky in rainfall.

Let’s find out more by listening to the podcast with Adrian O' Malley horticulturist and native plant expert. 

Rubus parvifolia

Not all fruiting vines or canes come from the northern hemisphere, Australia has quite a lot of its own.
These plants have similar fruits and are easier to grow than there northern counterparts so why are we growing them more? 

My experience is observing one such plant in Sydney Botanic gardens, scrambling on a stream bank near the Palm House. This plant is part of the native garden along with banksias, grass trees, lomandras, carpobrotus and many others, including a peppermint gum.

The habit of rubus species is to keep suckering and spreading, much like the non-native blackberry bushes, so take care where exactly you plant it in your garden.

Training-How to Get Started

 GARDEN AS THERAPY

Therapeutic Horticulture

You would think that yes gardening is therapy, so doing a bit of gardening would amount to therapeutic horticulture but you would be wrong.

• To understand therapeutic horticulture, you have to be across two areas:-health and well-being and horticulture. You can start from the health sector and then gain some qualifications in horticulture or vice versa..
• Therapeutic horticulture then means using gardening as an activity to improve people's health and well being through the use of plants . 
•  There are lots of courses that can assist you with training to be a therapeutic horticulturist.
• The next step is to gain some hours through volunteering with an organisation, eg aged care, through NDIS, and disability sector.
• It's also a good idea to join THA or Therapeutic Horticulture Australia https://tha.org.au.
