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.

- 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.

Real World Gardener Bring Plants Back to Life in Plant Doctor

PLANT DOCTOR
Can you bring a plant back to life?
We all love our garden, but sometimes a hiccup in garden maintenance brings distastrous results.
Take this next scenario:
You've come home from a couple of week's holiday and found that your treasured Spathyphyllum sp. or peace lily seems to have melted over the sides of the pot. It was a hot summer and the house-sitter didn't think to water it.
- What can you do to revive your dying plant?
Most people immediately assume that they should water it, but an extra dose of water can actually harm a plant that doesn’t need it.
- However, in this case, a good dunk in a bucket of water will remove most of the plant. There will be some dead leaves of course.
Out in the garden, there's a similar scenario, with small shrubs looking dried with burnt and scorched leaves.
They're not necessarily dead yet, so how can you tell?
The first thing to do is scratch the bark with your fingernail to see if there's some green underneath the outer layer.
If yes, then happy days, because with a bit of TLC, this plant will be brought back from the brink.
Also test if the limb or branchlet is still supple or snaps when you bend it.
If the stems are brittle, and brown inside when you cut it with a pair of secateurs, then the plant is dead and can’t be saved.
- Perhaps your buxus hedge is only half dead. Trim back the dead stems and give it a good water, adding a seaweed drink to the watering can. That can revive the plants no end.
Dead branchlets on my buxus hedge
One last chance.
When the plant above ground is all dried up and dead looking, there is a chance that new growth will spring from the roots, depending on what it is of course. Australian natives are good at springing back to life if you cut them to about 5 cm above the ground.
Diagnose the Problem
You need to weigh up whether or not your giving it too much water, (one of the most common mistakes) or not enough water.
- Has your peace lily got brown leaves that are dry around the edges or curled up? It's a sign of insufficient watering, so go water it!
Root rot symptoms.
This is when the plants' leaves look wilted, yet the soil is moist around the roots. In fact probably too moist if it's been sitting in a pot of water.
More than likely, your plant has root rot and the only way to save it,(slight chance), is if your spray it with Yates Anti-Rot which contains phosacid. This will only work if you've caught it in time and the leaves are able to take up the phosacid and translocate it to the roots.
Another option is to replant it into drier soil, which is easier if it's in a pot in the first place.
Don't Fertilise Yet
Fertilising now will stress the plant further and possible cause root and leaf burn. Wait it out a couple of weeks to let the plant recover, then add a gentle fertiliser at half strength.
Burnt Leaves
![]() |
Bromeliad needed more shade. |
Australia's hot summers can burn leaves of plants, particularly if the ground is very dry.
If it's in the ground and the leaves keep getting burnt every year, dig it up and move it to a shadier spot in the garden.
If it's in a pot, that's an easy fix to move to a better spot.
Frost damage on plants looks similar to leaf burn from too much sun.
If you're expecting more frost because it's only the start of winter, invest in a some horticultural fleece, and throw it over the plant on frosty nights. Leave the burnt leaves for now, because they will protect the lower leaves that haven't been burnt.

PLANT OF THE WEEK
Scientific name:Hoya species.
Common name:Wax flower
Family: Apocynaceae
There are some plants that quietly go about their business without too much fuss making them a little unnoticed in your garden.
- So why is it that they're not stars in the garden?
![]() |
Hoya carnosa |
Let’s find out more.
I'm talking with Karen Smith editor of Hort Journal, www.hortjournal.com.au and President of the Interior Plantscape Association.You could best describe hoyas as evergreen perennial twining creepers or vines.
- They have simple entire fleshy leaves in opposite pairs.
- The leaf shape varies considerably, with one species having heart shaped leaves: Hoya kerrii.
- being in the Apocynaceae family, their stems often exude a sticky substance.
- Most hoya don’t mind being a little rootbound, as they are used to growing epiphytically, so I don’t often repot my hoya.

PLANT OF THE WEEK
Chamaedorea elegans: Parlour palm
Do you love or hate palm trees?
The gardening community is divided into two groups, those that love the palm trees and those that hate them.
Probably because people persist in growing the environment weed, the cocos palm, which although grows really fast, is particularly ugly.

Chamaedorea elegans: Parlour palm |
There are many more well behaved palms and more lovely palms out there.
So let’s find out.
I'm talking with the plant panel were Jeremy Critchley of www.thegreengallery.com.au and Karen Smith, editor of www.hortjournal.com.au
Chamaedorea elegans is in the class of smaller palm trees, that is also one of the most palms sold around the world.
You can keep the parlour palm indoors for many years, but planted out in the garden under other leafy palms or larger leaved shrubs, it grows as a bushy alternative to the single trunks of most other palms.
Plus, you don’t have dropping palm fronds like you do with cocos palms and a few others.

Indoor Plant Pests Under Control
Over the past few weeks, we’ve talked about what plants you can grow indoors wherever you live in Australia.
Quite a few in fact can cope with all weather conditions for the far north of Australia to Tasmania.
Despite all your loving attention though, some plants can be susceptible to pest attack, or just like plain unhealthy, making you think you did something wrong.
Not necessarily true, so let’s find out about looking after indoor plants
That was Julia Levitt Director of www.sticksandstonesld.com.au
PLAY: Indoor plants-pests_2nd August 2017
Even the best plant owner will come across pests.
The trick is to keep an eye on your plants and act quickly as soon as you see something wrong with your indoor plant.
Why are we having plants indoors again?
Apart from plants reducing carbon dioxide levels in your home, did you know that people with plants in their homes have less stress, and plants have been known to contribute to lower blood pressure?

Indoor Plants for Warm Climates
The most important elements required for healthy houseplants include light, water, temperature and humidity.
If any or all of these factors aren’t properly met, your houseplants will inevitably suffer.
You might be sweltering under the fans in the heat of a subtropical summer but what about your indoor plants?
Dieffenbachia |
Can they cope or is this the climate where they thrive the best?
So let’s find out more in this new series on indoor plants.
I'm talking with Julia Levitt, Landscape Designer and Director of www.sticksandstonesld.com.au
The good news is that tropical plants usually enjoy warmer conditions and don’t perform well once indoor temperatures fall below 13-16 C.
Plus they like a lot of humidity, that means at least 50%, but better at 70% or more.
Most of the tropical, ornamental indoor plants with attractive foliage & colourful leaf patterns are suitable for hot & humid climates.
For example Dieffenbachia or Dumb Cane, Dracaena, house ferns of many kinds, Tricolor plant, snake plant, Philodendron, Money plant, Syngonium etc

Alocasia species
For an instant tropical feel, plants with large leaves are one of the main choices.
Some of these belong in the Alocasia family originating from a bulb or rhizome.
Alocasia amazonica |
But will they grow in your district.
Let’s find out
That was Jeremy Critchley www.thegreengallery.com.au
PLAY: Alocasia 21st August 2019
Jeremy mentioned these varieties of Alocasi to watch out for.
Alocasia macrorrhiza, Alocasia zebrina and Alocasia amazonica, are all outstanding cultivars.
The latter has very dark green leaves with prominent veins, edged in white, while the back of the leaf is purple.
Slow growing but hates the cold.
Jeremy thinks that it looks a bit like an African mask.
Don’t be like me and forgot they die down in winter.
Luckily I didn’t throw it out.

Real World Gardener Cool Pilea pep is Plant of the Week

PLANT OF THE WEEK
Pilea peperomioides: Pilea pep
This plant has a really interesting backstory.
- It’s common name is Chinese Money plant or Friendship plant, but I think there’s a few plants around with those same common names.
So as I always say, you need to know the scientific name to avoid confusion if that’s the case.
Let’s find out.
I'm talking with Jeremy Critchley, www.thegreengallery.com.au
Pilea peperomioides or Pilea pip,as it’s called in Jeremy’s nursery, was discovered and grown years before scientists ever got a hold of it.
It never occurred to anyone, that it was a new species until a member of the public want to know it’s real name.
Easily grown indoors or on a warm verandah because it doesn’t like to be below 15 degrees C much
- Hot Tip: healthy Pilea peperomioides plants produce baby plants both from their roots and their stems.
- Keep it away from direct sunlight.
- Likes to be kept moist but not overly wet.
- Although it can be kept outside in warmer regions, Pilea peperomioides is only suitable as a houseplant in most locations. It doesn’t appreciate temperatures below 10 °C and should be protected from sudden temperature swings.
- Pilea peperomioides will produce little plantlets growing in the soil next to the mother plant a. Once these have grown to a size of around 5-7 cm they are large enough to separate.
- Cut away the plantlet with a sharp, clean knife. They should already have their own root system and can simply be potted up.
