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.
- At first the graft union may seem all fine and dandy, but if you see shoots from below the graft union, you may have a problem Houston.
- Shoots from below the graft union could signal failure of the graft and the rootstock is trying to take over.
- Keep on rubbing off these shoots and hopefully it's only a minor abberration.
- If this persists, you may find the top part or scion is slowly dying, so time to start all over.
You’ll also need the correct root stock.

- Switch to grafting methods.
Practice makes perfect and I would recommend wearing gloves before attempting to do any type of grafting.
So What is Grafting?
- The scion has to be a particular size and be related botanically speaking to the rootstock. That means you can't graft an apple onto citrus rootstock, because apples are in the family 'rosaceae' and citrus are in the plant family 'rutaceae.'
- 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.
You’ll also need the correct root stock.
Let’s find out more by listening to the podcast. I'm talking with Margaret Mossakowska of www.mosshouse.com.au

Small Space Gardening in the Kitchen Garden

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.
Making the right choice
- Before any planting, determine the movement of the sun in your small space and and note down the hours of sunlight and shade in each part of your small space/courtyard.
- Choose those edibles that like all day full sun for those spots that get 6 hours plus of sunlight such as tomatoes.
- Leafy vegetables such as lettuce, rocket, Swiss chard and kale, don't mind a bit of shade throughout the day if your have only 3-4 hours of sunlight.
- If you only have morning sun then choose vegetables such as carrots, celery, and dwarf beans.
- For those spots with morning shade and afternoon sun, the choice is climbing cucumbers, climbing peas and beans.
Soil prep is key for Corinne.
-
The raised garden beds are made up with homemade compost, worm castings and bought in compost and other organic material.Grow cucumbers on a lattice made of string.
Think of vertical spaces
-
Think about growing vines like cucumbers and zucchinis and even nasturtiums, vertically.
I'm talking with Corinne Mossati drinks writer and founder of the gourmantic garden website.
Don’t be put off by lack of space you may have because no space is too small to have plants, even if it’s just herbs on the kitchen windowsill.

Saturday Nov 06, 2021
PLANT OF THE WEEK Number 2
Scientific Name: Atriplex nummularia
- The leaves impart a salty flavour if your dry and crumble them and sprinkle on food.
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.

Australian Native Raspberry in Plant of the Week

PLANT OF THE WEEK
Scientific Name: Rubus parvifolia
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.
Listen to the podcast to find out more.

SUCCESS WITH CORIANDER
Coriander leaves |
Coriander is easy enough to grow but being in the carrot family,(Apiaceae) its green leafy tops can look not only like other herbs, but other vegetables!
- My guest, Toni Salter in the podcast, calls it the 'primadonna' of herbs.
- Soil is too dry
- Too little water at the right time.
- Poor or impoverished soil.
- Poor drainage in your herb garden.
- Temperatures too warm for it's liking.
- Temperatures too cold for it's liking
- Transplanting-the worst sin.
- TIP: Always sow the seeds directly into the position where it will grow.
Coriander seedlings |
When to Sow in Australia
For sub-tropical and arid zones, you have August to September;Temperate districts, sow the seeds from September until the end of November,
In cool temperate zones, October to November,
- Sow your seeds about 1 cm deep, cover them and keep them moist.

In fact the whole herb, including the roots can be ground up to make a Thai Green Curry paste.

Winter Savoryvs Thyme in Spice it Up

SPICE IT UP
SAVORY VS THYME
Often there’s a couple of herbs that look alike and even have similar flavour profiles.
If you had them growing together in the herb garden, you may even confuse the two because of how closely they look to each other.
If you rubbed both herbs without knowing which was which, you would most likely think they both were the same herb.
- Winter savory, unlike thyme, is not sold as a cut herb in the produce aisle of your supermarket.
- Confusingly there is a 'summer savory' which tends to die off in winter and usually not come back.
- I've never seen the seeds of savory being sold however if you have a pot of winter savory that's overgrown and become leggy, follow these tips to refresh it.
- Dividing the roots in spring, will rejuvenate the plant.
- Start off by trimming about a third of any wrapped or circling roots.
- Divide the root ball into thirds or quarters, making sure that each section has a healthy piece of root and stems with green leaves attached.
- Remove one-third of the top growth, and trim away any dead or damaged stems and leaves.
- Re-pot into new containers and gift some to your friends.
But can you substitute one for the other?
Wild thyme growing amongst a rocky outcrop |
- Did you know there are over 100 varieties of thyme?
- The wild thyme of Provence is known for its strength of flavour. Think 'herbs de Provence' is a blend with this wild thyme.
- You will find winter savory, Satureja (sat-you-rea) montana, as a plant sold in most garden centres.
- So time to get some of your own.

PLANT DOCTOR
FUNGUS GNATS
These tiny flying things can swarm around your indoor plants but other than annoyance, are they killing your plants?
Those tiny little flies that hang around your fruit bowl or indoor plants aren’t always that same thing.
Sometimes they’re confused with fruit flies, or even ordinary house flies, but none of those two are correct. Inevitably they’re up to no good but how to tell them apart?
- There are fungus gnats and fermentation flies.
- they are attracted to different things.
- Fermentation or vinegar flies tend to hang around the fruit bowl, especially if you've got overripe fruit because vinegar flies are attracted to sugars.
- Fungus gnats are smaller, flitting around erratically: the adults of which are attracted to moisture.
- the adults are doing much if anything to your plants other than laying lots of eggs, although there is evidence that they can transmit plant diseases.
- The larvae can be the problem because the feed on the roots of your plants.
Fungus gnats -magnified heaps. |
- Remember: Vinegar or fermentation flies are attracted to sugary treats, such as over-ripe fruits, whereas fungus gnats are attracted to moisture such as overly wet potting medium.
- Greenhouses can also have an outbreak of fungus gnats.
- Keep your soil medium a bit on the dry side.
- Drench the potting mix with neem oil which will control the juvenile stages.
- Make a sticky trap using vaseline to trap the adults.
- Use a type of mulch the prevents the adult fungus gnats burrowing into the soil to lay the eggs.
- Worst case, repot with fresh potting mix.
- Greenhouse control can be with predatory insects.

PLANT DEFICIENCIES:
But still the plants look sickly, or perhaps a bit yellow, or they’re just not putting on any growth.
Does that sound familiar?
- So what’s the problem?
Basic pH test kit |
- Ideally the ideal pH range that gardeners should strive for is pH 6 - 7.5
- This is the range that the major nutrients of NPK are available to the plant the most.
- Some plants such as rhododenrons and azaleas like a like a low of pH6.
A good tip when taking soil samples from your soil is to get a sample from just below the surface for an accurate reading.

PLANT NUTRITION UNPACKED
Major Nutrients
Have you ever asked yourself "how do plants take up nutrients when you spread fertiliser around them on the ground or dilute it into liquid ?"
- What went wrong?
- So What Are These Nutrients?
- Nitrogen:Phosphorus:Potassium or NPK:
A selection of fertilisers - Kylie's main mantra is NPK refers to shoots:roots;fruit
Without the major nutrients, your plants may not grow and develop roots, stems leaves and flowers properly.
If you know what and how much to give your plants, the plants will be healthier and more productive.
Just remember to read the NPK amounts on the bag or packet of fertiliser.
Let’s find out more about what plants really need.
