Climbing Don Juan
Rosa 'Don Juan'
This vigorous climbing rose produces an abundance of fragrant, deep red blooms that repeat throughout the growing season. Perfect for covering fences, arbors, or walls, Don Juan combines the classic beauty of red roses with the dramatic impact of a climbing habit that can reach impressive heights.

Harvesting
Harvest Climbing Don Juan roses when the petals have deepened to a rich crimson and the blooms have fully opened, feeling soft yet structured with slight give when gently squeezed. This cultivar's repeat-flowering nature means you can enjoy continuous harvests throughout the growing season rather than waiting for a single flush, allowing you to deadhead spent blooms to encourage additional flowering cycles. For optimal fragrance and longevity, cut roses in early morning after dew dries but before heat stress sets in, selecting stems with at least three sets of leaves below the cut to promote robust regrowth and fuller plant architecture over time.
Bloom time: Fall, Spring, Summer
Storage & Preservation
Climbing Don Juan roses are best kept in a cool location with high humidity. Store cut blooms in the refrigerator at 34-40°F in a vase with fresh, cool water and floral preservative, which extends vase life to 7-10 days. For longer preservation, dry roses by hanging them upside down in a dark, well-ventilated space for 2-3 weeks to create lasting arrangements. Alternatively, press individual petals between parchment paper under heavy books for 4-6 weeks to preserve them for crafts or potpourri. Rose water extraction is another option, simmering petals gently to capture their fragrance in a shelf-stable liquid.
History & Origin
Climbing Don Juan (Rosa 'Don Juan') is a cultivar grown commercially. See category-level varieties for general species history and origin information.

Companion Plants
Garlic, chives, and alliums are the most practical companions to plant at Don Juan's base. Their sulfur compounds are thought to deter aphids and may reduce black spot (Diplocarpon rosae) pressure — in our zone 7 Georgia gardens, where that fungus can start stripping leaves by late May, every bit of help matters. Lavender and catmint pull in pollinators and beneficial insects, stay low enough to avoid shading the cane base, and don't compete hard for water at the 1-2 inches per week Don Juan needs. Marigolds (Tagetes spp.) do similar pest-deterrent work and cost almost nothing to seed out along the trellis front.
Black walnut (Juglans nigra) is a hard no — the juglone it releases through its root system will stress or outright kill the rose, and you won't immediately connect the cause to the symptom. Large trees are a different problem: their canopy cuts into the 6+ hours of full sun Don Juan needs, and their root systems will quietly drain the soil moisture before the rose ever gets it. Impatiens aren't toxic to the rose, but they're susceptible to several of the same soil-borne pathogens and there's no good reason to crowd them against the base.
Plant Together
Lavender
Repels aphids, spider mites, and other rose pests while attracting beneficial pollinators
Garlic
Natural fungicide properties help prevent black spot and powdery mildew on roses
Marigolds
Repel aphids, whiteflies, and nematodes while adding vibrant color contrast
Chives
Deter aphids and Japanese beetles while improving rose fragrance and health
Clematis
Shares similar growing conditions and creates beautiful layered flowering display
Catmint
Repels ants, aphids, and rodents while attracting beneficial insects
Alliums
Strong scent deters aphids, thrips, and other rose pests naturally
Parsley
Attracts beneficial insects like hoverflies that prey on rose aphids
Keep Apart
Black Walnut
Produces juglone toxin that can stunt rose growth and cause yellowing leaves
Large Trees
Compete for nutrients and water while creating too much shade for optimal rose blooming
Impatiens
Require frequent watering which can promote fungal diseases in roses

Troubleshooting Climbing Don Juan
What you'll see, why it happens, and what to do about it.
Black circular spots with irregular, feathered edges on leaves; leaves yellowing and dropping, sometimes heavily by midsummer
Likely Causes
- Black spot (Diplocarpon rosae) — a fungal disease that overwinters on infected canes and fallen leaves, then splashes up onto foliage during rain or overhead watering
- Poor air circulation from dense or unpruned canes
- Watering late in the day, leaving leaves wet overnight
What to Do
- 1.Strip and bag (don't compost) all fallen leaves; NC State Extension's IPM guidance is clear that getting infected material off the ground breaks the disease cycle
- 2.Prune out cane infections in winter, cutting 4-6 inches back into clean wood and sanitizing shears between cuts
- 3.Switch to drip irrigation or water at the base early in the morning so foliage dries well before dark
- 4.Mulch the root zone in late winter to reduce soil splash onto the lower canes
White powdery coating on young leaves and new shoot tips, often worst on fast-growing spring and fall flushes
Likely Causes
- Powdery mildew (Podosphaera pannosa) — thrives when days are warm (70-80°F) and nights are cool, which describes Georgia springs almost perfectly
- Overfertilizing with nitrogen, which pushes the soft new growth the fungus prefers
What to Do
- 1.Pinch off and dispose of the most heavily infected shoot tips before the spores spread further
- 2.Back off high-nitrogen fertilizer; one application of a balanced 10-10-10 at budbreak is plenty for most seasons
- 3.Thin the interior canes to open up airflow — Don Juan can stack up dense growth fast at 8-14 feet on a trellis
New shoots with excessive thorniness, abnormal red coloration that won't fade from mature leaves, or broom-like shoot proliferation on one or more canes
Likely Causes
- Rose Rosette Disease (Rose rosette virus), vectored by the eriophyid mite Phyllocoptes fructiphylus — NC State Extension notes that hyper-thorniness is a near-certain diagnostic sign
- Glyphosate drift can mimic the witches'-broom symptom, so rule that out first if you've sprayed anywhere nearby
What to Do
- 1.If you see two or more of these symptoms together — excess thorns, retained red leaf color, distorted growth — the plant almost certainly has RRD; dig it out and bag it immediately
- 2.There is no cure, and delaying removal puts every rose on your property at risk
- 3.Scout surrounding wild Rosa multiflora, a major RRD reservoir throughout the Southeast, and cut it out if it's within a few hundred feet
Clusters of small soft-bodied insects on new buds and shoot tips; buds deformed or failing to open
Likely Causes
- Aphids (most commonly Macrosiphum rosae, the rose aphid) — populations can double in days during spring flush when new growth is coming fast
- Absence of natural predators, often because broad-spectrum insecticides have cleared out the beneficial insect population nearby
What to Do
- 1.Hit the colonies with a firm stream of water from the hose three mornings running — this knocks back most infestations without any chemical at all
- 2.If pressure continues, insecticidal soap applied directly to the clusters works without wiping out the ladybugs and parasitic wasps that will arrive on their own
- 3.Ease up on high-nitrogen fertilizer in spring; the soft, fast growth it produces is exactly what draws heavy aphid pressure
