I WOULD like some advice on growing roses up established large trees and whether a rambler is the best choice as opposed to a climbing rose? M. Clarke, Kirkby Lonsdale

It sounds like you need a rambling rose as opposed to a climbing rose. Climbers are most suited to the smallest most accessible trees, sides of buildings, fences and large frames. They require regular pruning as opposed to ramblers that are not at all demanding, requiring only the bare minimum, usually the removal of any wayward stems or damaged material. Ramblers are by far the most enthusiastic growers and once established will grow very vigorously. A large mature apple tree would be able to tolerate a rambler provide you reigned it in from time to time but anything smaller would drown under the weight. Ramblers are perfect for planting up large trees including evergreens such as yew, pine trees and holly. If you have a smaller sized tree then use a climbing rose. These are far less vigorous and more suited to the dimensions of a small garden tree. In the same way that you would happily plant a climbing rose on the side of your house but to plant a rambler would not be advisable unless you live in a substantial property with masses of wall space to cover. My other pointer would be to select the right cultivar of rambler, some are far more vigorous than others. Paul's Himalayan Musk is a glorious, scented rambler which does not get huge compared to something like Kiftsgate, which has the potential to become enormous. Check the details before you make your final choice.

When it comes to planting, the rose needs to be as close to the tree as you can get it. The trees root system will dictate this entirely. It might be necessary to build up the soil level to create some additional depth. To encourage your rose in the right direction, make an angled ladder to give it a helping hand and mulch it generously after planting.
