Virginia creeper (Parthenocissus quinquefolia) is a native vine to North America. These vine plants are now grown worldwide for their unique five-leaved foliage, rapid growth and adaptability.
As of now, the Virginia creeper vine is widely cultivated in gardens to adorn fences, arbors and buildings. The colorful leaves (formed only during autumn) of this vine are what makes it attractive.
About Virginia Creeper Vine
Virginia Creeper Vine belongs to the grape family (Vitaceae). These vines are perennial, woody and deciduous and can grow up to 50 feet. Its supportive structure called adhesive pads present in tendrils helps them effortlessly attach themselves to surfaces, such as fences, walls, trees or arbors.
These plants are highly versatile and can adapt to various growing conditions. There are many varieties of Virginia creeper plants, all of which can be grown either using seeds or by propagating the plant stem.
Virginia creeper vine also fruit. The berries produced by them are food for various birds, however, they are considered toxic to humans. These creeper vines are long-living and have a lifespan of over 50 years.
Preparing the Planting Location
Light: Virginia creeper can sustain in most light conditions. From full sun to full shade, any area can be chosen to plant these vine creepers.
Soil conditions: They are adaptable to various soil types such as clay, loam and sand. Just make sure that the soil is well-drained.
Temperature: Virginia creeper vines can tolerate as low as -20°F (-29°C) and as high as 90°F (32°C). This is what makes them a plant perfect for any geographical region.
Support: As the Virginia creeper vine grows tall about 30 to 50 feet, make sure that they will get support during growth. Planting along places like fence, walls and harbors will be perfect for their growth phase.
Planting
From seeds: If you are planning to plan the Virginia creeper vine plant from the seeds extracted from berries, simply allow them to germinate in cold and moist conditions. You can grow them in a plastic bag with moist peat moss or vermiculite and refrigerate them for 2 to 3 months.
After this stratification process, sow the seeds in containers filled with potting mix in the spring. As leaves start to develop, you can transplant them into your garden/ planting pots.
From stem cuttings: Virginiacreeper plants can also be propagated. Cut stems from a healthy plant (4 to 6 inches sections) and make sure they have at least one node.
Insert these cuttings into soil, around 1 to 2 inches deep from the soil's surface, preventing overcrowding. Optionally, you can also dip the cut ends into rooting hormone powder to promote root development before planting them.
After few weeks, check for root development by gently tugging on the cuttings. Once root formation has been confirmed, transplant the rooted cuttings into larger containers or directly into the garden.
Watering Schedule
Consistent soil moisture is necessary during the growing season of Virginia creeper plants. After planting, water Virginia creeper deeply and regularly during the first planting season. This is necessary rather than frequent shallow watering for successful root development.
As these plants possess a strong root system, they become drought-resistant once the roots are established. For container plants, regularly monitor the moisture as containers tend to dry out more quickly than garden beds.
Fertilizing Schedule
As already mentioned, Virginia creeper plants can grow in various growing conditions, as they are low-maintenance. A single application of the fertilizer is sufficient for these plants, favorably in spring.
Balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium (NPK) is considered best for fertilizing Virginia creepers. The fertilizers are applied around the base of the plant keeping a safe distance from the stem.
Watering the plant is recommended once in a while after the application of the fertilizer. This helps to dissolve the nutrients obtained from the fertilizers which can be directly absorbed by the roots.
Some tips for caring for the growth and maturation of Virginia creepers are listed below:
Pre-Plantation Care
Plantation sites with well-draining, fertile soil and partial to full sunlight should be chosen for the optimum growth of the Virginia Creeper plants.
Plantation Care
Plantation is best done when the weather is mild and conducive. Spring or autumn can be best for the establishment of the plant. As you plant them, make sure to fill the planting hole with soil in order to remove the air pockets. Water the plant thoroughly to settle the soil and to direct the plant toward successful root development.
Post-Plantation Care
Mulching: Mulching is important to conserve soil moisture, suppress weeds and improve nutrient content of the soil. Organic mulches like wood bark or wood chips are the best choices of mulches.
Mulches work by reducing soil's evaporation, acting as a barrier for the weeds, reducing soil's temperature and also by adding organic matter to the soil. Periodically replenishing the mulch is important to ensure the effective growth of the plant.
Pruning: Virginia creeper is a vigorous vine plant that can grow tremendously. It grows rapidly and can produce several feet of growth in a single year. So, it is important to prune it back to control its size and shape (and to make sure it does not encroach on your neighbor's area!).
Pruning Virginia creeper is best done during the dormant season, mainly during late winter or early spring before new growth begins. First, remove the dead, damaged, or diseased branches of the plant. After that, thin out overcrowded or crossing branches to improve air circulation and light penetration within the vine.
If you wish to make the plant bushy, prune the Virginia creeper back to lateral branches or buds. This promotes branching and results in a more dense, attractive vine.
Support: Being a climbing plant, the Virginia creeper plant requires support. For a vertical support, you can install a trellis against a wall, fence, or other structure. Trellis made of materials like wood, metal, or vinyl will be perfect to withstand the heavy weight of this plant.
It's best to plant this plant around already existing supporting structures like walls and trees. This allows plant to climb and twine around these structures without need of extra care.
For young Virginia creepers, training them to climb can be very helpful. The use of specific structures like stakes or bamboo poles can prove to be effective for these plants to adapt to climbing.
Virginia Creeper Berries Are Highly Toxic To Humans
Virginia Creeper Berries start to fruit in late summer to early fall. When ripen, the green berries turn dark blue or purple. As these berries fully mature, they get ready for consumption by wildlife.
Though attractive, these berries are toxic to humans. They are mildly toxic to humans if ingested and can cause gastrointestinal discomfort. The oxalic acid present in the berries is the reason behind nausea, vomiting, or diarrhea.
Therefore, it's best to appreciate the ornamental values of the berries. In case kids or pets are present near the plantation area, it is recommended to prune the berries before they ripen.
The mesmerizing fall color display of Virginia creepers can provide a beautiful backdrop in your garden. As autumn approaches near, the green-colored foliage of the creeper transforms into an array of vibrant hues, including shades of red, orange and purple.
The vivid fall coloration is what makes this plant gardener's favorite. As the autumn season draws to a close, the colorful foliages fade and eventually drop from the vine.
Disease and Pests
Virginia creepers generally possess well-developed immune systems. They can not be easily bothered by diseases and pests. However, they are less often infested and infected by certain pests and conditions which are listed below:
Leafhoppers
Leafhoppers are tiny insects that are green or yellowish in color. These insects feed on the sap of plants and can cause serious damage to the leaves. Leaf discoloration and curly are some of the serious effects related to the infestation of the caterpillars.
Mildews
Mildew is a fungal disease. In humid and warm conditions, these fungi appear as white, powdery spots on the leaves, stems, and sometimes even the fruits of the plant. If untreated, the fungi can spread to the whole plant thereby weakening it over time.
Leaf Spots
Leaf spots are associated with both bacteria and fungi. As a result, small brown or black spots are observed on the leaves. Over time, these lesions may enlarge and develop into spots with distinctive margins.
Caterpillars
Caterpillars are heavy feeders. Eight-spotted forester and grape leaf skeletonizer are some common caterpillars that are found feeding on the leaves of Virginia creepers. If not stopped from spread, the caterpillars can cause damage to the whole plant.
Management of Disease and Pests
For the management of insects and diseases associated with the Virginia creeper plant, the following ways can be adopted:
Pruning: Heavily infested (by insects) or heavily infected stems and leaves (by bacteria and fungi) need to be removed from the plant. This helps to stop the spread of the causative agents to the healthy parts of the plant.
Companion Planting: Planting marigolds or herbs can repel insects from infecting the Virginia creepers. This method helps to protect the plant from the leafhoppers.
Handpicking: Caterpillars should be removed from the plant by handpicking. Upon heavy infestation, use horticulture oils (such as neem oil), encourage natural predators or use biological insecticides.
Biological Control: Ladybugs, lacewings and predatory wasps can be introduced in the garden to stop leafhoppers and caterpillars. The introduced insects feed on the harmful ones, keeping the vines healthy.
Natural Remedies: Natural remedies such as neem oil or insecticidal soap help in controlling leafhoppers and caterpillars by suffocating them. These products can help control leafhopper populations without harming beneficial insects.
Use of Insecticides/ Fungicides: As a last resort, you can use chemical remedies as well. When the condition is severe, cautiously apply these remedies to the affected parts. For caterpillars, biological insecticide ( Bacillus thuringiensis also called Bt) is available. This product targets caterpillars specifically and is considered safe for beneficial insects, humans and pets.
