What’s on the show today?Fixing bean problems in Plant Doctor, Growing something unusual and salty in Vegetable Heroes; grow this palm instead of the weedy Cocos palm in Plant of the Week and all about Agapanthus in the Talking Flowers segment with Mercedes.?
Perhaps it’s not just disease but a horde of insects have descended.
|Powdery mildew on beans|
Let’s find out what you can do about this.
I'm talking with Steve Falcioni from OCP’s www.ecogarden.com.au
Whitefly, thrips and aphids control with eco oil or soap based spray to.
|Possibly bean fly damage on leaf|
You may as well pull them out at this stage as there is no control.
Caterpillars can be picked off or use Dipel.
Powdery mildew can be controlled with potassium bicarbonate spray such as eco Carb.
Other diseases, such as rusts and leaf spots is better prevented with cultural methods because chemical control is difficult and mostly ineffective.
Good sunlight is best for beans so not near overhanging trees.
No pods but plenty of flowers?
The main reason for no pod set is very hot weather.
Steve says, just be patient and wait for the weather to cool.
Of course, encourage pollinators into your garden with plenty of flowers near your veggie bed.
If you have any questions, either for me or for Steve, why not email email@example.com or write in to 2RRR P.O. Box 644 Gladesville NSW 1675.
- As far as the home gardener goes this plant is rare and exclusive.
- But there’s more.
- It’s highly ornamental, has a creeping or prostrate growth habit and is great in a pot.
- It’s very attractive and can withstand environmentally tough conditions, plus the glistening succulent leaves look like they are covered in frozen icy bumps.
- Botanically speaking it’s also quite novel because it seems to be able to switch between two modes of growing.
- I need to mention here that your normal every day tree shrub or groundcover is what’s termed a C3 plant.
- That means it needs sunlight to carry out photosynthesis which it converts to sugars, taking in carbon dioxide and giving off oxygen.
- Salty Ice plant grows like this when conditions are good meaning there’s plenty of rainfall.
- Another method that plants can grow by is called Crassulacean Acid Metabolism or CAM for short.
- CAM plants shut their breathing pores or stomata during the day but open them at night to take in CO2 which is stored.
- This CO2 is released inside the plant during the day and even though the breath pores are closed, it can carry out photosynthesis.
- Also, as the breathing pores are closed, that means that water loss is minimal during the heat of the day.
- How clever is that?

PLANT OF THE WEEK
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.
I'm talking with the plant panel:Jeremy Critchley of www.thegreengallery.com.au and Karen Smith, editor of www.hortjournal.com.au
Let’s find out.
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.
If it gets too tall for the room, give it a trim because being multi-branching, there's no risk of killing of the leader.
Plus, you don’t have dropping palm fronds like you do with cocos palms and a few others.
If you have any questions about parlour palms, why not write in to firstname.lastname@example.org
Agapanthus flowers are normally picked when the bud bract has fallen off and no more than three florets are open.
