How to Prune Roses

Learn How to Prune Roses with the Gro Garden Blog

July is a great month for planting new roses but is also the time to give your existing roses some attention for a fabulous display of colour and fragrance over the flowering season. July is the best time to prune your roses. In really cold frosty regions, you may need to wait until early August.
The task of rose pruning can be daunting, but roses are very forgiving and will bounce back beautifully. Winter rose pruning is important as it helps to reduce disease, improve air circulation, allows more light in and encourages good strong new growth. This allows the plant to put the energy into producing an abundance of beautiful blooms as the flowering time arrives.

These are some simple guidelines to follow.

      • Begin your pruning of bush roses by removing half of the existing growth. If the rose bush has not been pruned for several seasons, remove two thirds of the existing growth.
      • From the remaining plant, remove any dead, diseased, or damaged stems.
      • Remove any old woody branches.
      • Open up the centre of the plant by removing all inward growing stems. This will allow more light and air flow into the rose bush.
      • Prune the remaining stems to just above an outward facing bud. The new growth will then grow outwards and produce flowers around the outside of the bush.
      • Do not be afraid to prune these stems back to about 30cm to 40cm from the graft. It will look as if you have been harsh, but you will be soon rewarded with nice bushy plants full of lush new growth.
      • These final cuts should be at about a 45 degree angle. Make the cut so it is sloping away from the bud so that rain and dew won’t collect in the area where the bud forms onto the stem. This will help control any fungal problems.

Once Pruning is complete, give the pruned rose a good spray with a horticultural oil such as All Seasons Oil or Pest Oil to control pests that are hiding ready for the new growth to appear. Fertilise with a quality organic fertiliser suitable for roses and mulch with a nice thick layer of your garden mulch. It will not be long until the fresh new growth appears, and you will be rewarded with an abundance of beautiful fragrant blooms to delight the senses.
