How to Grow
Plant Rosa ‘Don Juan’ during the dormant season—late winter or very early spring—when the plant is readily available. Ideal siting requires a location receiving full sun for the best flowering and disease management, although very light shade is tolerated. The soil must be a medium moisture, slightly acidic, well-drained garden loam, ensuring roots do not sit in standing water.
Watering should be deep and consistent, preferably early in the morning to allow foliage to dry before evening. Avoid overhead watering to further minimize the risk of common fungal issues. Good air circulation is vital for vigorous, healthy growth; this is why selecting an open location or providing support structures is critical for this Large-flowered climbing rose.
Apply mulch during the summer months to help conserve soil moisture and keep the root zone cool while suppressing weeds. Deadheading (removing spent flowers) throughout the bloom period encourages the prolific rebloom this rose is known for. In colder reaches of its range (like Zone 5), ensure the crowns receive adequate winter protection.
Pruning for Rosa ‘Don Juan’ should generally wait until late winter or early spring. However, gardeners should strictly avoid pruning for the first two years after planting; this crucial delay allows the main canes to establish the framework necessary to support the mature climbing structure.
Landscape Uses
The inherent stature and vigorous climbing habit of Rosa ‘Don Juan’ make it an outstanding choice for structure and vertical accent planting. This red climber is frequently utilized as a pillar rose, trained over dedicated supports to achieve impressive vertical height. It performs exceptionally well when secured against solid structures such as sturdy walls, arches, or tall arbors.
Beyond individual statement pieces, Rosa ‘Don Juan’ acts as a dramatic backdrop in mixed perennial borders where its height can anchor the design. For an elegant effect, train this Large-flowered climbing rose over white fences or pergolas to maximize the contrast with its deep red flowers and glossy green foliage.
When selecting companions, choose plants that thrive in full sun and share similar medium water needs, avoiding competition directly at the base of the rose. Low-growing, non-invasive spreading plants or bulbs that die back before the rose foliage fills in make excellent foundation accents directly beneath the main structure.

Potential Problems
Roses, including Rosa ‘Don Juan’, face susceptibility to several common diseases, namely black spot, powdery mildew, and rust. Cultural practices form the primary defense; ensure good air circulation and avoid overhead watering to reduce humidity buildup on the leaves. In areas prone to summer rain, preventative fungicide applications throughout the active growing season are often necessary to maintain healthy, glossy foliage.
Common insect pests include aphids, scale, mites, and borers, which can plague the plant if left unchecked. Regularly inspect the stems and undersides of leaves for early signs of infestation. Promptly remove and destroy diseased or infected leaves during the season and during the thorough winter cleanup, as this helps break the disease cycle for the following year.

Companion Planting
When designing arrangements around Rosa ‘Don Juan’, focus on plants that thrive in full sun and medium moisture but do not aggressively compete for nutrients near the rose base. Low-growing, clumping ornamental grasses or smaller, deep-purple or white-flowering perennials work well as visual anchors underneath the high-reaching canes. Consider planting silver-leaved groundcovers nearby, as the lighter foliage provides a striking contrast to the deep red blooms and the glossy, dark green leaves of the rose itself.
Seasonal Care Calendar
Mid-to-late winter is the appropriate time to prune Rosa ‘Don Juan’ as needed, removing dead or crossing canes to improve air flow before new growth begins. During the active growing season, focus on consistent deep watering, especially during dry spells, and monitor weekly for the first signs of pests or disease, treating immediately upon detection. As autumn approaches, reduce nitrogen feeding and ensure all dead leaves are cleared from the ground before the heavy dormancy period to minimize overwintering fungal spores.
