AllRound Tree Service guide to pruning your roses
Growing roses is one of the world’s favourite gardening activities. Queenslanders love growing roses, too, although we have some challenges in our warmer climate, with heat and humidity. AllRound shares below our basic guide to pruning your roses in south-east Queensland.
Time to prune the roses
The classic advice to rose-growers is to prune in the eighth week of winter, or after the last major frost. In most of south-east Queensland, that makes the last weekend in July peak pruning season. If you are out and about this weekend, you are bound to see rose lovers in their gardens with the shears.
Where on the stem to prune
Generally, you should trim the bud the same distance above the stem as the width of the stem. So, if your stem is about 10mm thick, you should cut about 10mm above the bud. You can reduce the height of a large bush by around a third to a half this way. The buds you prune will propagate and make great new plants.
You can also prune out dieback and dead growth from bushes at this time. Look down near the base of the bush for larger dieback and use loppers rather than shears for these tougher stems.
Your bush might have some thin canes that produce little growth. Prune these out as well. A bush might even have many of these unproductive canes, and don’t be afraid to trim them all out. You can trim at an angle, but it is not really necessary. Your pruning will stimulate new growth at the cut point either way. See how easy it is to prune your roses in south-east Queensland?
The next step after pruning is spraying with lime sulphur. You should do this as soon as possible after pruning, in a couple of days or a week at most. The spraying will control the bacteria and fungus that gathers on the bush over winter. It will ensure the plant goes into spring and summer in good health.
Brisbane City Council is revitalising the famous rose gardens of New Farm Park in inner-city Brisbane. Stage 1 in 2017 added 700 new rose bushes. Stage 2 is underway and will involve another 2000 bushes. The Council will also add six new arbours and add attractive landscaping to the rose gardens of this favourite park. Work is expected to complete in August 2018. There couldn’t be a better time for roses in south-east Queensland.
