Topic and Question |
Answer | |

When should I
harvest the fruit after the flower flowers or before? The plants have a lot
of grubs eating the leaves does this hurt the tree, also do we have to save
the seed and replant when crop finishes or leave the plant for next crop of
fruit? |
Harvest rosella fruit as soon as they come away from the bush easily. If
you leave them longer they will be tough and fibrous. Pick the grubs off
by hand if you can or squirt them off with a hose. It’s the end of the
season so I wouldn’t be too worried about them. Save some seed for
sowing in spring for new plants as the shrubs are short-lived. |
|
I'm hoping you can help me regarding a couple of fruit varieties that I'm
trying to track down. One is a peach and a plum tree. |
Try either Daleys Fruit Tree Nursery in New South Wales or Flemings Nurseries in Victoria. They might be able to help you. If they don’t grow them they might be able to recommend a similar variety. | |

My photinias don't seem to be growing much and they are constantly being
attacked by bugs...what can I do? |
There are several possible reasons for plants not performing to your expectations. Being attacked by bugs tells me the trees are stressed. Too much or not enough water; overwhelming root competition from nearby trees; poor drainage; infertile soil and not enough light will cause your photinias (normally a robust shrub) to languish. Check all of these conditions and see if you can ameliorate the situation. | |

I am finding small yellow worms in a garden bed on a property where we
have moved. They are about 5cm, shiny and not slippery like ordinary
garden worms. I don't know if they are a grub and if I should leave them
in the ground, or dispose of them? I would so appreciate your advice. |
I would be taking a photo of the worms and sending it to your Dep’t of
Agriculture for identification and advice. They may be beneficial so you
don’t want to kill them if they are! | |

We have a 3yr tree in large tub which we wish to plant in the ground. We are
200kl south of Perth...when is a good time to do it? |
You would be okay to plant a citrus tree from a tub into the ground
during winter in your area. Dig a hole bigger than the rootball of the
tree and add some compost to the soil that is used for backfilling. Take
the tree out of the pot and check the rootball; tease out some roots if
it appears to be potbound. Water in well with a seaweed solution. |

watering in homemade hothouse NSW
We have just exchanged the green shadecloth on our shadehouse for the
white plastic recommended by the manufacturers, to create a "hothouse"
for the cooler months. I want to see if I can grow tomatoes and extend
my basil crop right through till Spring. |
It may be possible to grow both tomatoes and basil in a hothouse during
the winter. Just keep the soil moist but not wet. I would be using all
drip irrigation if you can to lessen the incidence of fungal disease.
The problem maybe that if it is too cold for bees there will be little
pollination of the tomato flowers to produce fruit set. You might need
to pollinate the flowers yourself. I have heard that using an electric
toothbrush or similar works! You hold it against the tomato stem and it
vibrates the entire plant shifting the pollen around! | |

Plants dying for no apparent reason VIC Having lost many roses,2 citrus trees, a pear tree etc I
am concerned there may be something in the soil (fungal?) How can I check
for this? The plants seems very healthy then seem to die almost overnight |
It may be fungal attack but it may be the extended dry period we had
this summer – I lost quite a few trees and plants seemingly overnight
too. Try contacting your Dep’t of Agriculture for advice. Some soil
testing labs can test for fungus as well as pH. I would get a
horticultural consultant to come and visit – I think they would be worth
every penny. | |

An orange tree bought in a nursery
several years ago and left potted for 3 years was planted in ground 3
years ago. As yet it has budded only twice and not fruited at all. Any
ideas? |
Possibly the tree has not sent out roots into the soil. It might be
worth digging it up this winter and checking the root ball. If it is
still in essentially the same shape as the pot, some root pruning might
be necessary before replanting. Pay attention to drainage, watering,
fertiliser and sun. Citrus trees like good drainage, plenty of water
especially during summer, feeding in spring/summer and full sun not part
shade. | |

A friend has given me a couple of chilli plants, the plants look very
healthy a couple of chillies have started to grow but have just started
to turn a blackish colour on small areas of the chillies. Is this
normal, if not what can i do to fix it? |
I’m not sure if this is normal or not. Chillies like hot weather and can start to look sick when the weather cools. Black spots could be a result of wet feet, cool weather, bacterial infection or even sun scorch! At this time of year if I wanted to grow chillies it would be in a pot in a hothouse or on a sunny kitchen ledge. |

Hi, i have two grafted panama red passionfruit one approx 14 months the
other 6 months. The older vine has an abundance of fruit the younger one is
also fruiting profusely. Due to a lack of bees i resorted to hand
pollinating which has proven very successful. My problem is that the fruit
takes ages before changing colour when i have removed one from the vine the
skin is extremely thick, seeds are not completely formed and the pulp is
quite bitter. I composted before planting have mulched around both vines
applied fruit and citrus fertilizer and have also sprayed with seasol. Can
you tell me if this is common with young vines or am i missing out on doing
something. |
I think you’ve had quite a bit of rain recently where you are (and therefore less sun). That might be a reason. Otherwise you are doing everything else right! I was told to always leave the fruit of a passionfruit inside for a few days before eating it. Then the flavour goes from sour to sweet. | |

We have a garden bed built of concrete blocks so it retains some heat, is
underneath a concrete verandah, and has a northerly aspect which receives
direct sunlight in winter but no direct sunlight in summer. A watering
system can be installed if needed. What plants would best suit this
environment? |
The plants that first jump to mind are succulents (no watering system needed). Then I think of bromeliads and hardy ferns and things like monstera and philodendron. For colour impatiens should be okay. | |
|
I have some copra, surplus from my wifes horse feed. I was wondering if
it's ok to add to the garden, soil, veggies, citrus, etc. I believe it's
just crushed/ground coconut. |
I believe copra for horse feed is high in oil and protein. I’m not sure if it is suitable for putting on the garden. Perhaps you could try some in a small area before spreading it everywhere. Keep an eye out for any fungal outbreaks or if it makes the soil hydrophobic (water repellent). | |
|
training/tying VIC What is the best thing/product to use to secure two
pencil pines into an arch shape?
|
I think the best thing would be strips of velcro. Then you can easily adjust the tension. You can buy it from nurseries expressly for this purpose. I would not be using wire, fishing line or cable ties as they can cut into the bark if forgotten. | |
|
Nourishment when first planting trees VIC We have been given the advice that Molasses together with Seasol ( 5 litres/1litre/1000litres of water ) put into the hole prior to planting trees is very beneficial. Has anyone heard of this? |
I would certainly recommend a seaweed solution but I don’t know about the molasses! I did a quick search of the internet and found conflicting opinions about using molasses. Maybe try it with a few trees and a few not and observe the results. | |

cordyline potted indoor plant NSW I have a large Cordyline in a pot in my kitchen. The tips of the leaves are turning brown. Is this because it's not getting enough light as it doesn't get a lot of light where it is or am I over watering it? |
It might be under or overwatering. Try this experiment: take it to the
sink and run the tap until water flows out the bottom. If the water runs
through very quickly, the potting mix might be hydrophobic (water
repellent). Take it out of the pot and look at the rootball! If it is
essentially still dry, try treating the soil with a soil wetting agent.
It’s best to water indoor plants thoroughly but rarely, rather than
briefly and often. Stick your finger in the soil up to the second
knuckle. If your fingertip is moist the plant is okay. It might also
need a bit more sun. | |
|
Identifying an unusual flower NSW I was wondering if you could tell me
the name of a plant I saw on holidays recently. It had leaves similar to
an agapanthus but slightly smaller, and had a flower kind of like a
bottlebrush, but with much thicker and less frequent stamen (maybe 1cm
apart) with filaments (I think) coloured a very strong purple with
almost fluoro pink anthers (again, I'm guessing on the terminology). |
I’ll take a guess and say it’s a bromeliad – possibly an aechmea. I have
one flowering now and it matches your description exactly. |
