Planting Conditions

Planting the Rose Birthe Kjaer™ involves creating the perfect conditions to ensure its lasting beauty and fragrance. Select a well-drained, loamy soil that provides excellent moisture retention without water logging. This rose variety thrives in locations that receive a minimum of six hours of direct sunlight daily, ensuring vibrant growth and blooming. When planting, dig a hole slightly larger than the root ball, ensuring that the graft union is at ground level, allowing for proper root development and stability. Ensuring that the graft union (i.e. where the cultivar joins the rootstock and the point from which the branches originate) is at soil level (not below as this is reported to increase the risk of rose dieback). Spacing is essential, with individual roses typically needing 2 to 3 feet of separation. Applying a layer of organic compost around the base helps regulate soil temperature, reduce weed growth, and retain moisture. By adhering to these planting conditions, you'll provide the perfect environment for Birthe Kjaer™ to thrive.

Watering & Feeding

Watering and feeding Rose Birthe Kjaer™ is vital for its vitality and ability to showcase its stunning features. When it comes to watering, strive for consistent moisture in the soil. Deep watering is essential, ensuring the roots are thoroughly saturated, particularly during hot or dry periods. Morning watering is advisable to allow the foliage to dry during the day, reducing the risk of fungal diseases. To prevent potential issues, avoid overhead watering and opt for methods like soaker hoses to deliver water directly to the base of the plant. Feeding is equally important. Slow release rose fertiliser is advised. Typically, two feedings in Spring and late Spring or early Summer are beneficial. However, take care not to over-fertilise with excessive nitrogen, as this can lead to vigorous foliage growth at the expense of blooms.

General Care

General care for the Birthe Kjaer™ Rose is vital to ensure its health and showcase its exquisite beauty. Regular pruning, typically during the dormant season in late Winter or early Spring, involves the removal of dead or diseased branches, shaping the plant, and stimulating fresh growth and continuous blooming. Practicing deadheading throughout the growing season by removing spent blossoms encourages new flower production. Vigilance against common rose pests, such as aphids and spider mites, is essential, with prompt action through appropriate remedies if needed. Feeding the rose is crucial, employing slow release fertiliser is advised for your Birthe Kjaer™, following recommended application rates and schedules.
