Pruning roses is an essential part of maintaining healthy and beautiful rose bushes in Australian conditions. Proper pruning can encourage new growth, improve the overall shape and appearance of the bush, and promote the development of larger and more fragrant blooms. In this article, we will discuss the best time of year to prune roses, how much to take off when pruning, the equipment needed, and the fertiliser needed to help recovery.
When is the best time to prune Roses in Perth?
The best time to prune roses in Perth Australia is during the dormant season, which typically occurs between late winter and early spring. In Perth, we have found that late July to early August is usually best. This is when the plant is not actively growing and is less likely to be damaged by pruning. Pruning during the dormant season also helps to encourage new growth and blooms in the coming season.
How much do I need to prune?
The first goal when pruning roses is to remove any dead, diseased or damaged wood. This can be identified by looking for wood that is dry, discoloured or has no buds or leaves. It is also important to remove any wood that is crossing or rubbing against other wood, as this can lead to disease and damage.
In terms of how much to take off when pruning, it is best to remove around a third to a half of the bush’s overall growth. This will encourage new growth and keep the bush from becoming too large and unmanageable. Be sure to make your cuts at a slight angle just above an outward-facing bud.
What equipment will I need when pruning roses?
When it comes to equipment, you will need a pair of sharp and clean pruning shears or secateurs. It is also a good idea to have a small pruning saw on hand for removing thicker branches. Gloves and safety goggles are recommended to protect your hands and eyes from thorns.
Powered secateurs are a great option if you have a large number of roses to do.
What do I do after pruning my roses?
After pruning, it is important to fertilise the rose bush to promote recovery and healthy growth. A balanced fertiliser that is high in nitrogen and phosphorus is best for roses. Fertilise the roses every 4-6 weeks during the growing season. Black Marvel or Sudden Impact for Roses are both great options.
In summary, pruning roses in Australian conditions is an essential part of maintaining healthy and beautiful rose bushes. The best time to prune is during the dormant season, between late winter and early spring. When pruning, remove any dead, diseased or damaged wood and remove around a third to a half of the bush’s overall growth. Use sharp and clean pruning shears or secateurs and a small pruning saw. After pruning, fertilise the roses every 4-6 weeks during the growing season.
