Pruning your Knockout Roses
Do you see new shoots growing on the canes of your Knockout Rose Bush?
This is a good sign that it is time to prune.
1. When should the Knockout be pruned?
2. How much should be pruned?
- Your rose bush will typically triple in size after pruning so cut it back one foot and it will be three feet when it is finished growing.
3. How can I promote blooms?
- Knockouts will bloom from Spring to first Frost about every 5-6 weeks.
- There is no need to deadhead as they are self cleaning, but regular trimming will promote new growth and produce a tidier look.
- Use a balanced fertilizer or fertilizer formulated for roses. Experts recommend to apply after the first wave of flowering.
