What affects apples, even those ballerina ones growing in pots in the Plant Doctor segment; growing purple veggies in vegetable heroes, why you need a green wall in Design Elements and the queen of bulbs, in Plant of the Week.
PLANT DOCTORBlack Spot on Apples; Apple Scab
We all love to eat perfect apples but if you grow apple trees, then watch out for this.
The spots become bigger, in some cases joining up, the leaves turn yellow, and then drop off.
Well you’ll be surprised to learn that there is another type of black spot, don’t worry, it’s not on roses, but it appears on apple trees.
Let’s find out more..
The spots are also more irregular than blackspot on roses.
The problem with this fungal disease is that it also spreads to the apples, especially in humid weather.
If you have any questions apple scab or apple black spot. or have some information to share, drop us a line to or write in to 2RRR PO Box 644 Gladesville NSW 1675 and I’ll send you a packet of seeds.
VEGETABLE HEROESGROWING PURPLE VEGETABLES
What veggie can you think of that’s purple?
Did you say eggplants and then were a bit stumped?
What about purple carrots and beetroot?
Ok beetroot is sort of a reddish purple, but it can be considered purple, I’ll tell you why in a minute.
There’s also purple cauliflower and purple sweet potato not to mention purple chilli peppers.
Let’s not forget purple podded peas and purple king beans, red/purple mizuna, red Russian Kale, Red/purple cabbages. Need I go on?
So there are a few purple veggies out there.
Why should we grow purple veggies and why are they purple in the first place?
They’re purple is because purple vegetables contain pigments called anthocyanins, the same antioxidants found in red wine.
Think blueberries that are marketed as a superfood.
They also contain other health-promoting pigments such as betacyanins and carotenes.
Those anthocyanins and other pigments are good for our health.
Did you know though that anthocyanins are not the only cause of red colour in fruit and vegetables?
Betacyanins, members of the betalain family, are distinct from anthocyanins and the two pigments are not found in the same plants together.
Betacyanins also have anti-oxidant and anti-inflammatory properties which contribute to health.
Here are some growing information for some of these purple veggies.
In Arid zones, plant direct into the garden from April until June.
In cool temperate and temperate zones, February was the recommended time to sow seeds but you can sow seedlings until the end of May.
If your district is sub-tropical, transplant seedlings until the end of June also.
Purple caulie is a lovely coloured vegetable that contains all of the health properties of white cauliflower with the added bonus of extra anthocyanin (that lovely antioxidant that's so great for you!).
Just don't be surprised when it turns green once cooked. You can use purple cauliflower in any recipe that calls for cauliflower.
- To sow cabbage, in temperate, sub-tropical and arid districts, March until June is the best time, but temperate and sub tropical districts can have another go from August until November,
- In cool temperate areas March until May is best then again in August.
- Purple cabbages are not only lovely in colour, but extra good for you with more than double the amount polyphenols than green cabbage.
Purple carrots can grow year round in subtropical and arid climates.
- In Temperate zones, you have from September through to May,.
- In Cool temperate districts, September through to February, and in the tropics you can grow carrots from April to June.
- Different-coloured carrots carry different health properties. The purple carrot specifically has 28 percent more of the antioxidant anthocyanin than orange carrots.
- Eggplant seeds/seedlings can be planted in spring to autumn in tropical areas, spring to early summer in temperate zones and during late spring in cool climates.
Eggplant is also a good source of iron, calcium and a host of other vitamins.
- Purple Potatoes can be planted August to October, in temperate and sub-tropical districts.
- Arid areas August until December is your best time.
- In cool temperate zones, September through to January.
These potatoes add more than four times the antioxidants in comparison to regular potatoes, according to reasearch, and score as high as kale and Brussels sprouts in antioxidants.
Purple potatoes were once considered the "food of the gods,

You may not have thought of the idea of having a green wall in your garden.
You might’ve thought that they were really expensive.
Some facts first about green walls.
Green walls can provide:
• aesthetic improvements
• protect the building they are attached to because they shield the the building or fence from the sun.
• reduce building heating and cooling costs due to increased insulation
• increased property value
• a place to grow food
• rain water run-off management and water filtering/pollution reduction
• habitat creation and increased biodiversity
• cooling effect
• cleaner air, with less pollutants
But did you also know that green walls suit any size garden, even if you have a large garden?
How do you achieve this?
Let’s find out? I'm talking with Peter Nixon from Paradisus garden design. www.peternixon.com.au
They’re fine too.

PLANT OF THE WEEK
Nerines; Guernsey Lily (Nerine bowdenii)
Although it’s a bulb, it looks nothing like the flowers of regular common bulbs such as daffodils or tulips.
Did you know that exposure to cold temperatures can cause the flower heads to turn slightly blue?
If you like planting bulbs that you can set and forget, then Nerines are your thing.
Plant them with Cyclamens and Colchicums which are lower, as the stems of Nerine flowers are very tall, between 30 – 50 cms.
