Clematis 'Nelly Moser' Feeding Instructions
When planting a Clematis, it is important to build up soil with organic amendments (such as composted cow manure or mushroom compost) to retain moisture since the vine prefers a moist soil. A monthly feeding of liquid fertilizer or a complete organic fertilizer gives the vine the boost it needs for good growth and best flowering performance. There are slow-release organic fertilizers available in which a one-time application will last for 3 to 6 months. It's long been said that Clematis prefers their feet in the shade and their tops in the sun - this is a myth.
Clematis 'Nelly Moser' Pruning Instructions
Nelly Moser is a large-flowered hybrid Clematis. Prune in early Spring before foliage emerges by removing dead and weak stems, then cut back remaining stems to the topmost pair of large, plump green buds. This cut could be a few inches to a foot or two from the stem tips. Plants in this "Large-flowered Clematis" group have the tendency to become bare at the base as they mature. Underplant to help conceal the stems. You may be able to force a flush of new growth from the base by cutting the vine back to 18 inches immediately after the flush of bloom in June.

Clematis are generally resistant to pest's and diseases, however, Clematis wilt and powdery mildew can show up. To control Clematis wilt, immediately remove and destroy infected stems that begin to wilt (not from lack of watering), pruning below the point of infection. To discourage powdery mildew, plant in full to mostly sun and space plants for adequate air circulation. Morning sun is a must t dry morning dew from foliage. Water at the base of the Clematis vine to avoid wetting leaves when watering. During the season, pick off any diseased leaves where practical, and remove and destroy severely infected plants.
