With climbing roses, you must determine if it is a spring blooming plant, or one that blooms almost year round. Most blooms come from the lateral canes, so pruning out the weaker canes allows a vibrant cane to grow. Shaping occurs within this context as well.
Pillar roses produce tall, somewhat flexible canes - a cross between the bush and the climbers - and produce flowers on a consistent basis with minimal lateral training. Pruning should be much like the shrub rose.
Tree (standards) roses should be pruned much like the shrub rose; they probably need staking to bear the weight of the canopy.
Old Roses are usually divided into two categories,
- species native to Europe and western Asia (spring flowering)
- species native to eastern Asia (repeat flowering plants)
Old Roses are noted for their fragrance. Many of the modern roses (see the last blog) are the foundations of hybrids coming from Old Roses, working at making them more "landscape friendly."
Remember, now is the time to spray weeds, clean and sharpen your tools and reduce your watering. A deep watering once a week helps establish a strong root system. There are numerous organizations to help with more detailed information.
