Pruning serves several important purposes in helping to maintain the health and vitality of your roses. By removing the old stems and controlling the size and shape of the plant, you are allowing it to focus on the new growth.
It encourages the production of higher quality flowers, foliage, and stems. The best time to prune is in June or July. But if you live in a cold area of Australia, then wait until early August so that the frosts don’t knock back the new growth.
When pruning your roses, it’s important to follow these steps:
- Always use clean – sharp secateurs to minimise the damage to the plant.
- Identify the growth eye or bud from which new growth will emerge. Cut slightly above this point to encourage healthy growth. Growth eyes are typically found where a leaf has previously grown or is currently growing on the stem. It is best to select a growth eye that faces outward, as this will help maintain an open and balanced shape for the plant.
If you’re uncertain about which stems to remove, follow these recommendations:
- When in doubt, prioritise removing the oldest branches. The newer branches tend to produce stronger growth and more flowers.
- Remove any dead brown wood, anything crossing or rubbing and anything thin that shows signs of weak growth.
- Prune about a third back, always from the top and if you do this you’re going to find you get many more good shoots for flowers.
- Aim to cut at about a 45-degree angle.
- You are aiming for an open vase shape to reduce humidity around the leaves and promote good air circulation, therefore preventing black spot and fungal issues.
- If your plants have experienced fungal diseases such as black spot or mildew during the growing season, it’s crucial to take preventive measures. Fungal spores can persist in your garden, so it’s essential to collect all clippings after pruning and dispose of them in the bin. This practice helps prevent the spread of diseases throughout your garden, safeguarding the health of your plants.
What to do after pruning:
