large-flowered climbing rose

The large-flowered climbing rose (Rosa 'Lawrence Johnston') should be watered once a week or every 5-7 days, depending on the weather. During periods of hotter weather, it should be watered more frequently, potentially up to twice a week. When watering your rose, it's best to give it about 2 inches (5 centimeters) of water, either from rainfall or irrigated water. The water should reach the root system, which will consist of several feet of the plant's stem. Avoid getting the water on the rosebush's leaves as this can lead to the spread of diseases and fungi. If the soil is dry and there hasn't been sufficient rain, you may need to water your rose more often. When you water the rose, send the water through the soil and around the plant, especially the area surrounding the rose canes or stems. Doing this will help deliver adequate moisture to the root systems, promoting healthy and long-lasting blooms.

Large-flowered climbing roses (Rosa 'Lawrence Johnston') prefer full sun exposure for at least 6-8 hours per day in order to grow and produce flowers. However, they can tolerate partial shade, as long as they receive 3-4 hours of direct sunlight each day. These roses grow best if they are planted in sites that get morning sun and afternoon shade, due to the higher temperatures in the afternoon. During the hottest part of the summer, it's important to provide extra shade and water to ensure the best growth for the plant.

To properly prune a large-flowered climbing rose (Rosa 'Lawrence Johnston'), start by removing any dead, weak, or diseased canes. In early spring, any diseased branches should be pruned out, then in early summer, about 1-third of the oldest canes may also be pruned out. Next, shorten the remaining canes by about 1-half to 2-thirds, and finally pluck out any water sprouts (sucker growth) that appear during the season. This pruning should take place from late winter until early summer, with the most intensive pruning taking place in mid to late spring. With regular pruning and care, this climbing rose will produce an abundance of large blooms for years to come.
