A garden obelisk is an excellent way to support and display your shrub roses. Just put the obelisk over the rose, and secure the obelisk with pegs or spikes in the ground and tie the rose's branches to it. This is relatively easy to set up but it is important to make sure the obelisk is safely secured to the ground so that strong winds will not blow it over.
If you plan to grow rambling or climbing roses you should plant them outside your obelisk and train them around or thread them through your obelisk. You will find the stems of these roses are more
flexible than other types of roses which makes them easier to bend without causing them damage. When training climbing
or rambling roses twist the main shoots around the uprights to encourage flowering shoots to form low down, it is also better to train the shoots in the direction of their natural growth, before they have matured and hardened, particularly necessary for climbers that have stiff or semi-rigid shoots.
To fasten the rose shoots to the obelisk use rose ties or twine. It is good to use these because of the ease of loosening them when the shoots develop or for ease of releasing the shoots when pruning. When your roses have reached the top of your obelisk you should trim them regularly to make sure the rose keeps its shape.
