Expert tips
The key tip
Plant in rich, well-draining soil with at least 5-6 hours of sunlight. Prune lightly after flowering to rejuvenate. Fertilize sparingly (balanced formula) and keep soil aerated: tea roses fear root asphyxia.
The common mistake
Over-fertilizing: many think feeding more means more blooms, but excess creates soft, pale stems that are highly disease-prone. Roses are hungry, not greedy.
The pro's trick
Mulch 5-7 cm from autumn onwards: this regulates winter moisture and cuts fungal diseases by 60%. Tea roses in dry, mulched soil flower better and longer.
Seasonal watch
July-August: powdery mildew and black spot explode in warm-humid periods. Spray preventively from June with wettable sulfur or baking soda solution. Good air circulation drastically reduces epidemics.
Care
Watering
Water regularly and deeply during the growing season, ideally at the base without wetting the foliage. Keep the soil moist but not waterlogged. In summer, increase frequency; in winter or in cool climates, space out watering.
Light Exposure
Place this rose in direct sunlight, minimum 6 hours per day for abundant flowering. A south or west-facing exposure is ideal in temperate regions, while in hot climates some afternoon shade is beneficial.
Soil Preparation
Prepare soil enriched with compost or well-decomposed manure. Ensure excellent drainage by adding sand or perlite if needed. A slightly acidic pH (6 to 6.5) is optimal for Rosa odorata.
Fertilizing
Apply balanced fertilizer in spring, then rose-specific fertilizer monthly during the blooming period. Reduce in fall to allow the plant to prepare for winter.
Pruning and Training
Prune lightly in late winter to balance the shape and remove dead wood. Pinch young stems to encourage branching. Regularly remove spent flowers to stimulate new blooms.
Pest and Disease Prevention
Watch for powdery mildew and downy mildew, particularly in excessive humidity. Spray if necessary with natural fungicides. Improve air circulation at the base of the plant and regularly clean diseased leaves to prevent infestations.
Did you know?
Rosa odorata, introduced from Asia to Europe in the 19th century, is the direct ancestor of many modern repeat-flowering roses. Its name "tea-scented rose" comes from the subtle fragrance of its flowers, reminiscent of fresh tea. This rose revolutionized ornamental rose hybridization by bringing the genetic trait of repeat flowering, which was unknown in European roses until then.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
