MATT’S GARDENING COLUMN MAY 2019
Now that we are in the cooler months of autumn, I am looking forward to selecting and planting out the world’s most popular flower of course I mean Roses. Most of us have a favourite rose flower, maybe the most heavenly perfume, that can awaken all of our senses. Others talk about the form or appearance of the flower. How tight or loose petal forms the flower, the most unusual colour, repeat flowering potential, or even best suited to our climate in SE QLD. Some of the most trusted for their appeal, fragrance, and quality are varieties include hybrid tea roses. Suited for their strength of growth, flowering potential and generally long stems great for cut flower displays. Buds and flowers can be more pointed and tend to open slower than other varieties like floribundas. Floribundas advantage is they can offer a bouquet of multiple flowering buds free flowing all over, rather than producing single stemmed roses. Most are highly fragrant like Hybrid Tea roses, have excellent vigour and both certainly have performed well traditionally.
Some of my favourites in the Hybrid tea range are Mister Lincoln, this has deep red large double flowers. Has a strong perfume, that forms tight cupped flowers, on a single stem, great for the flower vase. Grows vigorously and is a high performer in our district. Blue moon has large double lilac blooms. Amazing perfume, highly scented and is an excellent variety to consider. Just Joey also has double soft orange very large and sweetly scented free flowering shrub, also has good disease resistance.
In the Floribunda range, proven roses are Gold Bunny offers profuse large double cupped lemon-yellow flowers. Continuously blooms high quality flowers, on a vigorous strong bush. The beautiful old-fashioned blooms of the Old Port rose are highly fragrant. Blooms of rich red to mauve colours on and a higher petal count type that our old-fashioned roses can only provide.
No matter which of the choice that you decide on either Hybrid teas or Floribunda most of these two varieties will perform very well for you, talk to our garden staff if you would like more information on selecting your cultivar.
The versatility of planting roses is amazing, whether in garden beds, mass displayed, or a single specimen used as an accent plant. In turf areas can create a wonderful appeal by planting into decorative, terracotta or glazed pots. Most of the guidelines for planting, care and maintenance remain the same. Roses need to have at least 6 hours of full sun a day to grow well. Increase your success with either adjusting soil with adding well composted manure, preferably add fresh garden soil, free draining is very important. Roses do not grow well in long periods of heavy soaked soils. Support plant growth and performance with applying rose fertilizer every three months to maximise flowering. In pots use a premium potting mix or speciality rose potting mix. An excellent addition to fertilizers is Triple Boost liquid tonic for boosting plants resistance to extremes and increasing blooms, as well longer life for cut flowers. Adding sulphate of potash on planting time is recommended to encourage root growth and builds plants overall health. If already planted out existing roses can be supplemented well with Silica Potash, very quick acting as is applied as a foliar spray. This will increase the general health of the roses root system, that can develop a stronger shrub that can repel pest and disease effectively. Disease and pest attack can be prevented with applying foliar spray dual action fungicide as well as insecticide, every few weeks. Regular deadheading spent flowers will also increase your blooms. With pruning, keep it as simple. In mid-winter July, I cut back shrubs by a half, taking care to formatively prune back into a vase shape shrub. Removing ill formed stems, or crossover branches rubbing against each other. After cutting rose bushes I use a fungicide to prevent dieback or disease getting into stems. Overall roses can offer us all such a great reward they are worth giving a try.
Keep Growing
