    The Hybrid Tea Rose 'Alexander' requires regular watering to maintain slightly moist soil, especially during the growing season. Water deeply once a week, about 1 to 2 gallons per plant, ensuring that the water reaches the deep roots. During hot or dry periods, water twice a week. Avoid overhead watering to prevent leaf diseases; instead, water at the base of the plant. In the winter, reduce watering frequency to prevent waterlogging as the rose is dormant.

  • sunLight

    Hybrid Tea Roses like 'Alexander' thrive in full sun conditions, requiring at least 6 hours of direct sunlight daily. The best spot for planting is an area where it will receive morning sun, which helps to dry dew on the leaves and prevent fungal diseases, while still getting ample sun throughout the day to promote vigorous blooms.

  • thermometerTemperature

    Hybrid Tea Roses such as 'Alexander' prefer a temperate climate with temperatures between 65 and 75 degrees Fahrenheit for optimal growth. They can survive short periods of colder weather down to 20 degrees Fahrenheit but require protection from extreme cold. High temperatures over 90 degrees Fahrenheit can stress the plant and may necessitate additional water and shade.

  • scissorsPruning

    Prune your Hybrid Tea Rose 'Alexander' in late winter or early spring, when the last frost is over, to shape the plant, remove dead or diseased wood, and encourage strong new growth. Cut back the rose by about one-third to one-half, making angled cuts above outward-facing buds. Remove any weak or crossing branches to improve air circulation, and deadhead spent blooms throughout the growing season to encourage repeat flowering.

  • circleLife cycle

    The life cycle of the Rosa 'Harlex', commonly known as Hybrid Tea Rose, begins with seed germination, although many garden roses are propagated via cuttings or grafting. Upon sprouting, the seedling grows into a young plant with foliage, during which roots establish and photosynthesis commences. As it matures, the rose bush enters a period of vegetative growth, producing stems and leaves vigorously. Once mature enough, typically in the spring, it develops buds that bloom into its characteristic large, fragrant flowers. After pollination, these flowers may develop into rose hips (seed pods), if not deadheaded, which contain seeds for the next generation. In colder climates, the rose experiences a dormant period in winter before resuming growth in the spring.

      Spring to Summer

    • The Rosa Alexander 'Harlex' (HT), commonly known as the Hybrid Tea Rose, is often propagated by cuttings, a method used widely for its simplicity and effectiveness. The best time to take cuttings is in late summer or early autumn when the wood is semi-hardwood: mature but still flexible. To propagate, one would cut a healthy piece of stem about 6 to 8 inches (15 to 20 centimeters) long, making sure it includes at least a couple of leaf nodes. The lower leaves are removed and the cut end is often dipped in rooting hormone to encourage root growth. The cutting is then planted in a mixture of potting soil and perlite or sand to ensure good drainage. It is important to keep the cutting moist and in a well-lit, warm environment without direct sunlight until roots develop, which may take several weeks.
