Roses add an element of beauty and a pleasant fragrance to any garden. They also provide aesthetic value when planted to climb up trees. Climbing roses can be trained to climb up anything and thrive, as long as they are established correctly. When planting climbing roses to run up trees, keep in mind some important steps to make sure they have a proper foothold.
Choose the planting site. Figure out what side of the tree receives the most amount of sun each day, as the roses need to be planted where they are in at least five to six hours of sunlight daily. Ensure that there is also good drainage at the planting site, which can be amended if possible.
Prepare the soil for the planting site, if necessary. For better drainage, combine equal parts of potting soil and compost to incorporate into the planting site.
Dig the planting holes. They must be one and a half to two times larger than the rose plant's root ball, and about two feet from the tree's base.
Set the rose plants into their holes. Backfill the soil so that the top is about 2 inches from where the rose plant's stem connects to the roots. Lightly pack the soil around the roots with the compost and potting soil mixture.
Use the twine to secure the main rose stems and vines to the tree trunk, which will act as a stake or trellis. Make sure not to tie any flowering stems, and keep the vines as horizontal as possible.
Water the rose plants generously after planting. Let the water settle so no air bubbles get caught around the roots. Add another light sprinkling of potting soil on top if the soil settles too much.
