How to Make Clematis Bloom All Summer

Clematis plants can live for decades with proper care, but they require firm hands to reach their full blooming potential. Planting them correctly and providing ideal growing conditions are all equally essential.

To keep clematis blooming throughout summer, they must be correctly planted, pruned, fertilized, and watered. Follow these simple guidelines to guarantee an eye-catching display every year!


Clematis plants thrive in full sun, but some varieties will tolerate partial shade. All require rich, moist soil that retains moisture. Clematis are avid feeders, so add organic material when planting and regularly fertilize with high-potash fertilizer throughout summer to maximize results.

To plant your clematis, start digging a hole twice the width and depth of its container. Add soil amendments like humus, compost, or any other suitable substance – such as fertilizers – into this hole to enrich its environment and minimize competing for nutrients against grass or other plants regarding water supply.

When pruning your clematis, remember that its type will impact when and how often it flowers. Group A (Spring-bloomers) clematis benefit from hard pruning early spring, cutting all vines to around an inch off the ground- promoting strong new growth while creating texture. Furthermore, this also encourages flower production!

Group B and C clematis produce blooms on old and new growth, usually blooming between late spring and early summer, then reappearing through fall. While these varieties may be a little less demanding than Group A varieties, hard pruning to two sets of fat buds a few feet from the ground should still take place each March to encourage strong, reblooming growth while eliminating seed heads, which would detract from its beauty.


Pruning is vital to keeping clematis blooming all summer long, and you must identify which of three pruning groups your clematis belongs to (Group 1, Group 2, or Group 3). Each blooms on different wood, so cut stems that correspond with each group.

Your Clematis belongs to Group 1 or Type 1. To keep it looking neat after blooming has finished, prune these plants after they’ve finished flowering to maintain their appearance neat and clean. As these vines can self-seed easily, remove their seed heads after flowering to prevent unwanted propagation of self-propagation.

Group 2 Clematis flower on old and new wood, producing two yearly bloom periods: early spring and late summer. Reblooming varieties such as Nelly Moser’, Bee’s Jubilee’ and Duchess of Edinburgh belong to this category of Clematis; after spring flowering, these should be lightly pruned with sterilized shears to remove deadwood and keep their shape.

Group 3 Clematis may rebloom on both old and new growth, making them ideal for larger-flowered hybrids such as Nelly Moser or Bee’s Jubilee. These should be pruned lightly after spring flowering to maintain neatness and tidyness.


Over 250 species and hybrids of clematis are available to choose from, each offering different cultivars and bloom times in your garden. Some varieties, like Midsummer Night or Bluebird, will begin flowering late winter or spring and continue through summer; others might start in midsummer or later into autumn; others rebloom annually from their same buds. Selecting an ideal variety for your growing zone is critical for optimizing blooms; ensure your local garden center carries suitable types!

Clematis plants require plenty of fertilizer. Start by applying low nitrogen products when soil temperatures warm in spring; spread granular fertilizers with ratios such as 5-10-10 around each vine’s base to provide ample nutrition. Many clematis enthusiasts also opt for organic high-phosphorous options like bone meal or liquid tomato feed containing potassium as the best solutions.

Herbaceous (non-woody) clematis that bloom during summer and fall will produce new flowers each year from buds on last season’s growth, but they must still be pruned annually in March to remove old stems and encourage reblooming. Though more forgiving if pruned too harshly, these types should still be pruned back to approximately 12 inches above a robust set of buds for best results.


Clematis prefer a well-drained soil that’s rich in organic matter. Before planting, amend your planting spot with compost and water regularly until the ground remains moist without becoming waterlogged; this step is especially crucial during its first year after being established.

Clematis requires at least four to six hours of sunlight daily for vibrant blooms, so shade from trees or shrubs should be avoided as much as possible. When planting, support should be provided for the vine to prevent injury while aiding it to establish robust root systems.

Once established, clematis tend to be drought-tolerant once watered regularly during spring and summer; occasional watering will still help preserve moisture for maximum bloom. Also, consider mulching around its vine to preserve moisture.

Assume an 8″ distance between the stem base and mulch (straw, leaves, or compost). Mulching helps protect plants from mowers and trimmers, keeps soil cool, helps reduce water needs by up to 40 percent, and potentially helps you save on additional irrigation needs.

Clivia thrives when planted among other plants, like roses or honeysuckle; their vines will need protection from wind and frost while providing an environment to display their showy blooms all summer. By grouping them with similar varieties like these perennials, such as Osmanthus, they’ll receive enough sun to produce blooms to fill their showy flowers!


In conclusion, extending the blooming season of clematis requires strategic care and attention. You can enjoy a spectacular display of clematis flowers throughout the summer by implementing proper pruning, providing suitable support, and selecting the right varieties. Cultivate a thriving and continuous bloom with these expert tips.
