Rosa x 'Double Knock Out®'

Shrub Rose

Tips for Homeowners:

Prune in spring when new shoots are beginning to grow.  The shrub will grow 3 times its size so cut back according to the desired finished height.  Although Knock outs are self cleaning there may a lull where the plant is about to begin a new bloom cycle so it is not necessary to deadhead.  Rose hips are few and do not trigger the plant to stop producing flowers.

Interesting Notes about Shrub Rose:

Shrub roses are popular for both their beauty and because they are easy to grow.  They are also very hardy which is ideal for the northern gardens where hybrid teas and floribundas are risky to grow.  The flowers are either single, semi-double or double and the fragrance varies per variety.  Rose hips on the shrub roses are almost as beautiful as the flowers themselves and will vary in size and color.  The shrub rose is more rugged and will withstand drought as long as the soil is well-drained and the pH is balanced.  Shrub roses prefer full sun, but will take limited shade.
