About this plant
The charm of deep blue nodding flowers is hard to beat. This modest clematis, flowering in April for several weeks, is one of the joys of spring. The flowers are held pendulously and the four petals (technically tepals) open out to reveal creamy blue staminoids within. The flowers are followed by the classic silken seed heads. The plant is best kept in check by removing some of the stems, taking them out to the base of the plant, immediately after flowering. This is beautiful grown over sturdy evergreen shrubs, or over a trellis or an obelisk.

Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.

Prune Clematis Group 1 - trim after flowering

Summer
Summer-Autumn · Planting
Support young plants
Provide support for young plants, and tie in any growth to the support to keep it tidy.
Winter

Apply an organic mulch
Apply an organic mulch to the plant taking care not to bury its stem or cover any young growth that emerges from its centre.
A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.
