WaterThe Dortmund rose requires watering once a week with about 1 to 1.5 gallons of water, making sure the soil is moist but not waterlogged. During hot and dry periods, the frequency should be increased to twice a week. It's important to water the plant at the base to keep the foliage dry and prevent fungal diseases. Less water may be required during rainy seasons or if the plant is established in well-retaining soil. Always check the top inch of soil for dryness before watering to avoid over-watering.
LightThe Dortmund rose thrives best in full sunlight conditions, which means at least six hours of direct sunlight each day. A spot in the garden that receives morning sunlight and some afternoon shade is ideal to protect the blooms from intense heat. Avoid placing it in full shade as this will reduce flowering and can lead to poor plant health.
TemperatureThe ideal temperature range for the Dortmund rose is between 65 to 75 degrees Fahrenheit. This rose can survive in temperatures as low as 20 degrees Fahrenheit in winter and can tolerate summer heat up to 90 degrees Fahrenheit. However, prolonged exposure to temperatures outside this range can stress the plant, potentially affecting its growth and blooming capacity.
PruningPruning the Dortmund rose is important to maintain plant health, encourage new growth, and improve air circulation. Prune in late winter or early spring by removing dead or diseased wood and thinning out crowded areas. Cut back the remaining canes by about one-third to one-half their length, always cutting just above an outward-facing bud. Deadheading spent flowers throughout the blooming season encourages repeat flowering.
CleaningAs needed

Life cycleThe Dortmund Rose begins its life cycle as a seed, from which a seedling emerges when conditions are favorable—generally in spring. The seedling grows into a young plant, developing roots, shoots, and leaves as it matures. The juvenile plant eventually becomes an established rose bush, entering a phase of vegetative growth where it expands in size and strength. During the growing season, typically late spring through early fall, the bush produces flowering canes which bear the vibrant red, single to semi-double flowers characteristic of the 'Dortmund' variety. After pollination, the flowers may develop into hips (seed pods), which mature and eventually release seeds, completing the reproductive cycle. In the dormant season, usually winter, the rose bush's growth slows, conserving energy until the conditions are right to begin the next growing cycle.
PropogationPropogation time
Spring-Early Summer
Rosa 'Dortmund', commonly known as the Dortmund rose, can be propagated successfully during late winter or early spring, before the plant breaks dormancy. The most popular method of propagation for this rose is through hardwood cuttings. This involves taking a cutting of about 6 to 8 inches (15 to 20 centimeters) from a mature, healthy stem that has recently flowered. The bottom end of the cutting should be cut just below a bud, and the top just above one, leaving several buds on the stem. The cuttings are then inserted into a well-drained soil mix, with about half of their length above the surface. To encourage rooting, a rooting hormone can be applied to the cut end before planting, although this is not always necessary. The cuttings should be kept moist and in a sheltered location until they have rooted, after which they can be transplanted to their permanent location.
