shrub rose

Shrub roses should be watered deeply about once a week during periods of active growth. The soil should be kept evenly moist, but not soggy. During hot, dry periods, water 2-3 times a week. Monitor the soil closely to make sure the soil does not dry out. Water in the morning or evening, avoiding the hot midday sun. It’s best to direct water at the soil level, keeping the foliage dry, to avoid fungal diseases. Mulch around the shrub to help keep soils evenly moist and help reduce weeds. Avoid overwatering and allow the soil to dry out slightly between watering sessions.

Shrub rose (Rosa 'Radcor' RAINBOW KNOCK OUT) plants will thrive best in full sun. This means they need to receive at least 6 hours of direct sunlight each day. During the spring and summer months, when the days are longer, this may be a natural occurrence. During the winter months, when the days are notably shorter, you may need to shift the location of the plant to ensure it continues to receive an adequate amount of sunshine.

Prune your Shrub Rose (Rosa 'Radcor' RAINBOW KNOCK OUT) lightly in early spring, just before its buds are ready to open. This encourages new growth and helps to keep the plant’s shape. To prune, start by removing any dead or damaged canes and cutting back thin and elongated growth. Then, cut back older canes that have bloomed in the past season and prune the remaining canes to an outward facing bud. This will help to improve air circulation and promote more new growth. Finally, cut out any crossed branches, and cut back the plant if needed in order to maintain a manageable size.
