Cotoneaster horizontalis

 

Rock Spray

Cotoneasters are popular garden shrubs, grown for their attractive habit and colourful fruit. Many deciduous species bring rich autumn colour to the garden. Some varieties are almost evergreen, only losing their leaves in severe winters. The evergreen species are useful for rock gardens, covering a wall or for borders. This shrub has pink and white flowers in the spring and then in the autumn it sports red berries.

Planting

From Early Autumn TO Late Autumn

Purchase a container-grown plant from a reputable nursery. The best time to plant cotoneasters is the autumn although they will also do well if planted in the spring. Pick a spot where you are certain you want to keep the plant as cotoneaster does not transplant easily. The best locations have full to partial sun and well-drained, alkaline soil. Avoid areas where the soil tends to experience saturation for extended periods. Plant ground cover plants 5 feet apart. Space larger plants about 4 to 6 feet apart.

 

Propogation by cuttings

From Early Summer TO Early Summer

Cotoneasters can be propagated with softwood cuttings taken in early summer. The use of a rooting hormone is highly recommended.

 

Propagation by layering

From Mid Autumn TO Late Autumn

Low growing species can be propagated by simple layering in the fautumn. Pin a low growing stem to the ground, using a piece of stiff wire bent into a U, leaving the last 6 to 12 inches of the stem exposed. Cover the pinned area with soil, then bend the tip sharply into a vertical position (for upright plants) and nick the bark on the underside of the bend. Provide a stake to hold it in place. Once the layer is well rooted, it can be severed from the parent and moved to another part of the garden.
