The rose has long been a source of fascination and meaningfulness for cultures around the world.
Cleopatra was believed to have covered the floor of her palace room with roses before Mark Antony visited for in those times anything which was said "under the rose" was deemed to be a secret.
For many of us Queenslanders though how to keep roses looking amazing feels like a state secret.
I often stare in awe at the pictures in magazines of roses elsewhere in Australia. How dare they have the climatic conditions to grow these plants successfully?
I have never claimed to know the secrets of growing roses in a climate where for about six months of the year we have what feels like 100% humidity.
Many rose growers out there will probably have a small heart attack at my way of growing roses but that’s ok, my way is the right way for me and maybe if you’ve never had any success in the past it may become the right way for you.
The first thing I needed to realise was that my roses may never look like they do elsewhere. The humidity we suffer is the cause of most rose problems. No amount of sprays, fertilisers or correct planting techniques will change the problems humidity brings.
To combat most of the rose problems such as black spot, fungus, bud worm that occur during the warmer months I trim and fertilise.
I don’t spray.
During the really humid months most of my roses look like bare thorny sticks. I find removing all the affected leaves, trimming back the plant and then fertilising with a slow release complete organic fertiliser like Organic Link works fantastically.
I always trim my roses like I am cutting the flowers off for a long stemmed vase. I personally can’t stand long straggly bushes so I make sure all my roses get a good prune continuously throughout the year. I also find a good dose of granular Sulphate Potash at least twice a year, Winter and Summer, helps with fungal problems and boosts blooms.
After pruning you can use a product like Steriprune which is designed to protect wounds against infections and die back. Come the cooler months and my roses are thick and lush and full of flowers. The few leaves that do get black spot or mould just get pulled off and when the flowers die, I still trim the stem right back like I am cutting it for a long stemmed vase.
To keep roses healthy and insect free I try to regularly liquid fertilise them with Rose Triple Boost and neem oil, fortnightly is ideal (but not always possible). When black spot is rife I alternate between the Rose Triple Boost and Silica and Potash Liquid fertiliser (certified organic).
Another organic alternative for black spot and rust is eco-fungicide. Eco-fungicide is a registered organic fungicide for the control of powdery mildew, black spot and rust in many plants including tomatoes, zucchini, roses, grapevines and geraniums. It attacks existing fungal infections and kills external fungal growth within minutes. Eco-fungicide also leaves an invisible protective coating that prevents new spores from germinating.
This Rose quote is so true even when growing roses. You must put up with all the disease, insects etc but it is well worth it when they bloom
To control insects some people like to use a pyrethrum based spray or neem oil.
All my roses are in full sun in pots and in the ground. I use Searles Platinum Potting Mix for the pots and Searles' Garden Mix for the ground. I mulch with Sugarcane.
Roses do not have the prettiest bush and they can sometimes seem a bit fussy but the reward of the rose is well worth it all.
