About this plant
A very pretty clematis that makes a pleasing show on a winter's day with the fine foliage and the tiny delicate bell-shaped creamy yellow flowers. Within the pendulous cup pink spots and streaks may be glimpsed. The foliage is another delight with sheeny dissected green leaves that have a rather ferny effect. This plant is one of winter's secrets, often only noticed by the perceptive. Note: Clematis cirrhosa forms can be subject to frost damage and need protection. Plant them on warm walls or fences, or against a south facing tree where the temperature is likely to be a few degrees warmer.

Spring
Spring - late · Outdoors
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.
Spring-Autumn · Outdoors
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.
Spring · Planting
Prune Clematis Group 1 after flowering
Clematis Group 1 prune: Prune immediately after flowering. Remove any dead, diseased or damaged wood. If it has got too large cut back and tidy any unkempt growth. This may include thinning slightly if the appearance is very congested.
This plant flowers on old wood which has had time to 'ripen' during winter. They are generally lightly pruned, but some containment may be needed for large and vigorous forms.

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.
