Thriving clematis plants may produce about blooms per season. The plants flower in mid to late spring. Prune early-flowering clematis just after the blooms fade, but no later than midsummer, to encourage new growth for the following season. Vines produce flowers in early summer and often again in late summer.
Prune large-flowered hybrids in late winter or early spring. Some late-flowering clematis varieties start to bloom in early summer and continue through fall. Prune them in late winter or early spring. Vines thrive in bright sunlight for six hours a day and cool, well-drained soil with neutral pH of around 7. If necessary, amend the soil with bone meal or superphosphate before planting. Support structures, such as fences, trellises and stakes, allow clematis vines to twine, curl and cling. Keep the soil wet, but not overly saturated.
Clematis vines are susceptible to several diseases, including leaf spot, clematis wilt and powdery mildew, according to PennState Extension. Suspect leaf spot Phoma if you see large tan or black spots on the plant's leaves. If your soil is too sandy, nutrients poor or the soil is overly boggy transplant clematis in the Spring to an area of the garden with more suitable soil amended compost.
Otherwise remove the clematis from the ground and dig out an area much larger then the root ball to add lots of compost and organic matter around the plant to ensure the soil conditions are more favourable for the plant to flower. Clematis prefer full sun at least 5 hours but can flower well with morning sun and shade in the afternoon.
In full shade the clematis vines grow extensively with lots of healthy looking foliage but the plant displays few if any flowers. Transplant any clematis that are shaded to an area with some direct sun or cut back over handing branches and other plants that can cast shade on the clematis to promote flowering.
However an interesting quirk of encouraging clematis to flower is that they bloom far greater with their roots in the shade with their leaves in full sun. Whilst this is true of many plants, there is a far greater requirement for clematis to have their roots shaded in order to grow well and flower. The roots of the clematis prefer to be in cool moist soil whilst their leaves are in full sun to promote blooms. A 1 inch layer of mulch on the soil surface helps to retain moisture and prevents the sun from shining directly onto the soil so the soil does not bake in Summer and that the roots remain cool.
Materials such as compost, leaf mould and well rotted manure are the most appropriate types of mulch for clematis as they all have a great capacity for retain moisture so that the root system remains cool in the Summer heat. Apply mulch around the base of your clematis in the Spring before the heat of Summer and again in mid Summer for optimal flowering.
Clematis can often benefit from fertilizer to boost the nutrients that are available, however it is important to find the right balance. Clematis does not tolerate consistent additional fertilizer in the same extent as competition standard roses. Too much nitrogen in the soil from applying fertilizer too frequently or in too great a concentration promotes foliage at the expense of clematis blooms. Clematis in poor or sandy soils, pots and containers or perhaps soils that have not had an application of mulch for years generally benefit in terms of flowering more from additional fertilizer then established clematis in well prepared soil.
If you have applied a high strength of fertilizer or have used fertilizer more then twice during the growing season then this can be detrimental to flowering. Scale back the use of fertilizer to a half concentrated application of well balanced NPK equal parts Nitrogen, Phosphorous and Potassium multi purpose fertilizer in the Spring for the optimal nutrients balance to ensure clematis flowers well for the following Spring. Some clematis varieties bloom on last years growth whereas other bloom on new growth in the Spring time.
If you prune clematis in the early Spring then you can stimulate lots of vines and foliage growth without flowers as you may have cut away the flower buds that develop on last years growth. It is best practice to wait till after flowering which occurs in late Spring or early Summer depending on the climate to prune back and shape your clematis.
Pruning just after flowering encourages more growth so more flowers can be displayed the following year and keeps the plant looking more orderly and tidy.
Pruning each year ensures that the clematis vines do not overlap and become a matted tangled mess which can also limit blooms. Clematis 'Evijohill' bears unusual double lilac-pink flowers through summer and early fall.
