Background

Clematis patens 'Hagley Hybrid' is a compact, free-flowering climber prized for its abundant, shell-pink blooms with contrasting reddish-brown anthers. It flowers reliably from early summer into autumn, making it a dependable choice for trellises, arbors, and container growing.

Best grown with its head in the sun and its roots in the shade, this clematis benefits from a cool root run achieved by mulching or underplanting. As a member of the large-flowered hybrid group, it blooms on new growth and responds well to hard pruning in late winter to encourage vigorous, well-shaped plants.

Common problems

Clematis Wilt

Symptoms

Sudden wilting and blackening of stems and leaves, often just before flowering. Whole shoots collapse rapidly while roots remain healthy. Caused by the fungus Calophoma clematidina.

Treatment

Cut affected stems back to ground level and dispose of them, not in compost. Water at the base to keep foliage dry, improve air circulation, and plant the crown deep so the plant can regenerate from below soil. Apply a fungicide if the problem recurs.

Powdery mildew

Symptoms

White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.

Treatment

Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.

Aphids

Symptoms

Clusters of small soft insects on new growth and flower buds.

Treatment

Knock off with a strong jet of water. Ladybirds and lacewings are natural predators. Insecticidal soap as last resort.

Spider Mites

Symptoms

Fine stippling or bronzing on leaves, faint webbing on undersides, foliage drying out during hot, dry weather.

Treatment

Spray foliage with a strong jet of water to dislodge mites. Apply insecticidal soap or horticultural oil to leaf undersides; repeat every 5–7 days as needed.
