Vines are plants with long, long stems that make their way up in the world by clinging to or twining around a support. As long as there is something sturdy to mount, true vines can do it alone, or with minimal help. There are a handful of other plants that we call vines—Bougainvillea and climbing roses (Rosa) are two popular examples—that neither cling nor twine and cant ascend without help. Since they also want to be head and shoulders above their fellows, you must tie them to or drape them over a support.
As with other woody plants, the time and energy youll spend pruning vines has much to do with the plant you select and the spot in which you place it. Youll save yourself a good deal of anguish if you pick a vine that can live comfortably in the space you have. Old wisterias can produce primary stems the size of tree trunks and have been known to pry off drainpipes and gutters. Even my tropical wax plant (Hoya carnosa)—which hangs indoors and receives far less light than it needs—has managed to creep under the molding of the window, emerge on the other side, and now threatens to escape to the outdoors through a tiny tear in the screen.

How vines grow affects how much pruning they may need. Among the most intrepid are species that climb by using aerial rootlets and species like Virginia creeper (Parthenocissus quinquefolia) that have holdfasts, little suction cups that grab onto walls and other surfaces. Also exuberant (and sometimes invasive) are many vines that twine, such as Wisteria, bittersweet (Celastrus scandens), and honeysuckles (Lonicera). Somewhat less rampant are the vines that ascend by using tendrils, such as Clematis, grape (Vitis), and passionflower (Passiflora). But only somewhat.
Unlike many shrubs and trees that do well without ever being thinned or cut back, even vines grown in sizable settings may require regular pruning to keep them healthy, productive, attractive, and under control. Many vines just dont know when to quit—or in which direction to grow. They must be taken in hand early on or they will be collapsing trellises, pulling down fences, and obscuring windows and doors.
Once vines have developed adequate roots, most just keep on growing above ground. To keep a vigorous climber healthy, you must do the following:
Reducing a vines mass not only ensures that your fence wont collapse, it also allows light and air to reach the plants interior. Dont forget, though, that pruning doesnt just reduce mass: It can increase it. Heading back stems encourages new growth.
If youve purchased a container-grown vine—standard nursery fare these days—no pruning is mandatory at planting time, especially with evergreen vines. But heading back, which will encourage new growth, may be a good idea if your plant has long, spindly shoots with few leaves or only a single stem. Bare-root plants should be headed back by no more than a quarter before they are planted to allow the vine to balance its growth below and above ground. Be sure to cut out any damaged or dead roots and stems, or stems that have minds of their own and appear determined to grow into the neighbors yard rather than up your trellis.
Vines in their first or second year tend to sprout and elongate stems more than produce leaves and flowers. Pinching back shoot ends helps balance their growth. Also, woody vines tend to flower more generously on shoots that are horizontal rather than vertical, so keep that in mind as you direct and shape your climbers. Twining vines especially grow from upper buds and tend to lose their lower leaves. They may need severe heading back to promote foliage near the ground. If you want a compact vine, head back stems throughout the growing season; if you want a vine to ramble, keep your pruning shears in their scabbard.
The guidelines for pruning mature vines are similar to those for pruning deciduous shrubs. Species grown for their foliage can be pruned throughout the garden season, but early spring before leaves appear puts the least stress on the plant. Vines that flower in summer and fall on the current years growth, such as honeysuckles (Lonicera), should be pruned in late winter or early spring. That schedule gives the plant time to produce new shoots and flowers. Prune vines that flower early in the garden season on shoots produced the previous year—jasmines (Jasminum) and Wisteria are two—immediately after their flowers fade. Most hardy vines fall into this category.
Except…like all general rules, there are exceptions, the most important of which concerns vines that produce ornamental or edible fruits. Even if postflowering pruning is called for, wait until spring, or the fruit crop will be lost.
Pruning mature vines can be difficult, because their long stems become tangled. Dont be tempted to yank. Instead, prune one stem section at a time until youve cut out all you want to remove.
With its delicate pink or purple blooms and lacy foliage, the Alpine Stork’s Bill flower (Erodium) brings elegance to any garden. But without proper pruning, these flowering perennials can become leggy and unkempt This in-depth guide covers when, how, and why to prune your Alpine Stork’s Bill for optimal health and beauty. Let’s get snipping!
Pruning is essential for:
- Encouraging bushy, compact growth
- Removing dead or damaged stems
- Promoting more profuse blooming
- Improving overall plant health
Alpine Stork’s Bill should be pruned in late winter or early spring before new growth emerges, Additional trimming can be done after peak flowering in summer
Always use clean, sterile pruners to avoid transmitting disease. Make cuts just above leaf nodes or buds. Remove no more than 30% of growth at one time.
Deadheading for Continuous Blooms
Deadheading or removing spent flower heads redirects the plant’s energy into producing more blooms instead of setting seed.
To deadhead:
- Snip wilted flowers as soon as petals fade
- Cut back to the first set of healthy leaves
- Make cuts at an angle to prevent water pooling
Regular deadheading will maximize flowering from spring until fall frost.
Cutting Back Overgrown Plants
Over time, Alpine Stork’s Bill can become leggy and congested. Hard pruning rejuvenates overgrown plants.
In early spring:
- Cut all stems back to 6 inches above soil level
- Remove dead or diseased growth entirely
- Disinfect tools between cuts
- Allow the pruned plant time to regrow bushy and vigorous
Drastic renewal pruning every 2-3 years promotes lush, healthy new foliage and abundant blooms.
Maintaining Shape and Size
For container-grown Alpine Stork’s Bill, prune to:
- Keep compact and prevent legginess
- Maintain desired size and shape
- Improve air circulation and light penetration
On in-ground plants, prune to:
- Control spread in garden beds
- Maintain boundaries and prevent encroaching
- Remove old wood to stimulate new growth
Proper shaping creates an aesthetically pleasing plant that fits your space beautifully.
Pruning Flower Stalks
The long, upright flower stalks of Alpine Stork’s Bill add height and dimension. But older, spent stalks should be removed.
- Cut back any faded or dried out stalks
- Prune damaged or broken stalks entirely
- Remove congested areas for better air flow
- Follow stalks down to healthy growth or leaf nodes
This tidy up keeps your Alpine Stork’s Bill neater between major prune jobs.
Avoiding Common Mistakes
Steer clear of these all-too-common pruning pitfalls:
- Severe pruning too late in summer risking dieback
- Cutting improperly resulting in “bleeders” or unsightly dieback
- Allowing stubs by not pruning back to a healthy bud or leaf node
- Failure to sterilize pruning tools spreading disease
- Over-thinning interior growth exposing sensitive branches to sun scalding
Proper timing and technique prevents many issues and distresses. When in doubt, do less rather than more.
The Takeaway: Prune Purposefully
Pruning does wonders for keeping Alpine Stork’s Bill vibrant and floriferous. Follow these tips:
- Time pruning in early spring before new growth emerges
- Deadhead spent blooms all season long
- Renew leggy plants with hard spring pruning every 2-3 years
- Maintain shape and restrict size on potted plants
- Remove faded flower stalks and congested areas
- Always use clean, sharp pruners and sterilize between cuts
With some knowledge and the right technique, pruning your Alpine Stork’s Bill will be an easy, rewarding endeavor. Soon you’ll have the prettiest “haircut” in the garden!
Clematis: The Queen of Vines
Clematis are among the most beautiful flowering vines but also among the most puzzling when it comes to pruning. Most flower without any pruning—at least for a few years—but if you wait too long, the severe pruning that may be necessary can be a death knell. All clematis benefit from being pinched back to the lowest pair of healthy buds when planted, and pinched again in their second season if growth is slow and stems sparse.
The key to pruning clematis safely and effectively is to know what class of vine youre growing. Once you know what youve got—another argument for saving the tags that come with plants—the rest is easy. The experts have divided the genus into three groups.
Group One, the spring-flowering clematis that bloom on old wood, should be pruned lightly after they blossom. Old, overly tall woody vines can be pruned hard, but it may take a season or two for them to recover.
Prune Group Two, the late- and twice-blooming clematis, which blossom on both old and new wood, lightly in late winter when the vine is dormant. After their first flowering, prune them more heavily—cut back about a third of the shoots to the lowest pair of healthy buds—to induce new growth for fall flowers.
Group Three, the late-flowering clematis, which bloom on new wood, should be cut back to the lowest pair of healthy buds in late winter to early spring, before new growth begins.

A Vine-by-Vine Guide to Pruning
Some vines dont have to be pruned every year, but all vines need basic care: Remove dead, damaged, and diseased stems; stems that are tangled or head in the wrong direction; stems that are weak or unproductive; unwanted suckers; and spent flowers. Beyond those cuts, the general goal when pruning vines is to keep them healthy, vigorous, and productive, and to help them follow their natural inclinations at the same time they fulfill your needs.
Actinidia species, kiwi, silver vine. Flower on new wood. Do maintenance pruning—to train or control—on silver vine (Actinidia polygama), variegated kiwi vine (A. kolomikta), and other ornamental actinidias after they flower. Save severe or renewal pruning for late winter to early spring when the vine is dormant.
Aristolochia macrophylla, Dutchmans pipe, pipevine. Dutchmans pipe flowers on old wood, but it is grown for its foliage and can be pruned anytime to remove tangles and errant shoots. Save renewal pruning for late winter to early spring when the vine is dormant, then cut oldest stems to six inches.
Bignonia capreolata, crossvine, quartervine, trumpet flower. Flowers on new wood. Prune to remove weak, overgrown, or errant shoots in late winter to early spring; head back shoots to encourage new growth. Needs minimal pruning.
Bougainvillea species, bougainvilleas, paper flowers. Most bougainvilleas flower intermittently throughout the year on new growth, with the heaviest bloom cycles (followed by a rest cycle) coming in spring and fall. Prune after flowering ends. Remove dead, tangled, and errant wood and suckers; head back long stems to encourage new flower buds.
Campsis radicans, trumpet creeper, trumpet vine, cow-itch. Flowers on new growth. Head back stems in late winter to early spring to control growth and encourage branching. Remove suckers and root-prune to discourage underground runners. Cut stems to ten inches to renew.
Celastrus scandens, American bittersweet. Blooms on new wood. Prune in late winter to early spring. Remove suckers, tangled and weak stems, and stems that have fruited; head back last years growth; pinch shoot tips in summer to encourage branching. Do not confuse this native species with Celastrus orbiculatus, oriental bittersweet, which is invasive.
Cocculus carolinus, Carolina moonseed, coral beads. Flowers on new wood; prune as needed in early spring.
Ficus pumila, creeping fig, climbing fig. Remove older stems in late winter or early spring to promote immature foliage form. Pinch stem ends to promote branching. Needs little pruning.
Gelsemium sempervirens, Carolina jessamine, evening trumpet flower. Flowers on old wood. Head back lateral shoots, remove dead stems, and prune to shape after flowering ends.
Humulus lupulus, common hop. Flowers on new growth. Commercial growers cut their hop vines to the ground in late summer to harvest the cones. Hop vines grown for ornament should be cut to the ground in late winter to early spring. Root-prune to control underground runners.
Hydrangea petiolaris, climbing hydrangea. Flowers on new wood. Head back in early spring; remove stems that have pulled away from their support. Prune hard to renew.
Ipomoea species, cypress vine, morning glory. Ipomoea species, including morning glory (I. tricolor) and moonflower (I. alba), the p.m. version of the morning glory, flower on new wood. Cut vines to the ground in late winter to early spring in zones where they are perennial.
Jasminum nudiflorum, winter jasmine. Flowers on old wood; prune immediately after blooms fade. Winter jasmine, primrose jasmine (Jasminum mesnyi), and common, or poets, jasmine (J. officinale) need minimal pruning.
Lonicera, honeysuckle. Prune Henrys honeysuckle (Lonicera henryi), trumpet honeysuckle (L. sempervirens), woodbine (L. periclymenum), and trumpet honeysuckle cultivars (L. x brownii) in late winter to early spring to control growth; remove weak shoots; head back long stems. Renew old vines by cutting a third of oldest stems to the ground. Japanese honeysuckle (L. japonica) and its cultivars are extremely invasive and not recommended.
Mandevilla splendens, mandevilla. Flowers throughout the growing season on old wood; little or no pruning necessary.
Menispermum canadense, Canada moonseed, yellow parilla. Flowers on new wood. Postpone pruning until spring to preserve ornamental fruits. Root-prune to control underground suckers.
Parthenocissus species. Most Parthenocissus species, including Virginia creeper, or woodbine (P. quinquefolia), and Boston ivy (P. tricuspidata), need pruning only to control or direct their growth. Grown for their leaves, they can be shaped throughout the garden season; wait until late winter to early spring to do radical pruning.
Passiflora species, passionflowers. Bloom on new growth; remove tangled and unproductive stems in spring. Need only moderate pruning unless grown for fruit production.
Periploca graeca, silkvine. Flowers on new wood. Little pruning needed; head back in spring to stimulate and direct growth.
Rosa species and cultivars, climbing and rambling roses. See “Roses.”
Schisandra species. Schisandra species, such as Chinese magnolia vine (S. chinensis) and bay star vine (S. coccinea), flower in spring on old wood, but postpone pruning until late winter or early spring to preserve their ornamental beaded fruits.
Schizophragma species, hydrangea vine. Both Japanese hydrangea vine (Schizophragma hydrangeoides) and S. integrifolium flower on new wood. Prune in early spring; little pruning is needed.
Vitis species, grapes. Flower on new growth. Grape species traditionally are pruned in late winter. Ornamental grapes, such as V. vinifera Brandt, V. vinifera Purpurea, and V. coignetiae do not require the careful and severe pruning that is needed when growing grapes for their fruits.
Wisteria species, wisteria. Native wisterias, including American wisteria (W. frutescens) and Kentucky wisteria (W. macrostachya), are less vigorous and showy than Asian species, which are invasive. They flower on short, leafy shoots, or pedicels, that arise from buds on the previous years wood. To encourage flowering, head back stems after blooms have faded; if necessary, head back a second time in late winter, leaving at least three or four buds. Train shoots to establish a framework or increase vine height; head back once the desired height and width have been achieved. Old plants can be renewed by severe pruning, almost to the ground.

What do stork’s Bill seeds look like?
The seeds are about 6 mm long, hairy, brown in colour and club-shaped. Typically this weed flowers from June to September. Prevention of Stork’s Bill is less expensive and less time-consuming than trying to control it. Make sure when you are seeding a new area you are doing so with certified weed-free seeds.
How do I get rid of stork’s Bill?
Finally, make sure to give all equipment that has been in infested fields a good clean, to make sure no seeds are transferred. There are some good cultural control methods for Stork’s Bill, starting with spring and fall cultivation in crop fields, which will destroy the seedlings that have grown in summer and fall germination.
When should stork’s bill be treated?
Stork’s Bill needs to be treated as early as possible due to the fact that it quickly advances through its growth stages. Effective control of Stork’s Bill can be achieved by MCPA or 2,4-D applied at 500 g/L formulation.
