Question 2

Planting and Growing Pachysandra terminalis

Accepted Answer

Light:

Partial to full shade. Pachysandra will tolerate some morning sun, but avoid hot, direct afternoon sun, which can scorch the leaves.

Soil:

Well-drained, humus-rich soil is preferred.
Pachysandra tolerates a range of soil types but performs best in slightly acidic to neutral soil (pH 6.0-7.0).
Amend heavy clay soil with compost, peat moss, or other organic matter to improve drainage.

Watering:

Establishment (First Year): Water regularly, keeping the soil consistently moist but not waterlogged.
After Establishment: Pachysandra is relatively drought-tolerant once established. Water deeply but less frequently, allowing the top inch of soil to dry out between waterings.
Water more frequently during periods of extreme heat or drought.

Planting (Bare Root):

When to Plant: Early Spring (before new growth emerges) or fall.
Soak Roots: Before planting, soak the bare roots in water for 1-2 hours to rehydrate them.
Prepare the Hole: Dig a hole slightly larger than the root mass.
Planting Depth: Plant the crown (where the roots meet the stem) at or just slightly above the soil surface. Avoid burying the crown too deep, as this can lead to rot.
Spread Roots: Gently spread the roots out in the hole.
Backfill: Fill the hole with the amended soil, firming it gently around the roots.
Water Thoroughly: Water deeply after planting to settle the soil.
Mulch: Apply a layer of organic mulch (shredded bark, leaf mold) around the plants, keeping it away from the crowns.

Planting (Potted Plants):

Follow the same general steps as above, but you will not need to soak the roots.
Gently loosen any circling roots before planting.
Plant at the same depth the plant was growing in its container.

Spacing:

Space plants 6-12 inches apart. Closer spacing will result in faster coverage.

Fertilizing:

Pachysandra generally does not need much fertilizer if planted in rich, organic soil.
If desired, apply a light feeding of a balanced, slow-release fertilizer in early spring. Avoid over-fertilizing.

Maintenance:

Pruning: Minimal pruning is needed. You can trim the edges to maintain a neat appearance or to control spread.
Weeding: Weed regularly, especially during the establishment period, until the Pachysandra forms a dense mat.
Thinning: If the planting becomes overcrowded, you can thin it out in spring or fall by digging up and replanting sections.

Pests and Diseases:

Generally, pest and disease-resistant.
Watch out for slugs and snails, especially in damp conditions.
Leaf blight (Volutella pachysandricola) can sometimes be a problem, especially in overly wet or crowded conditions. Ensure good air circulation and avoid overhead watering if possible.

Winter Care:

Pachysandra is hardy.

Important:

Shade Tolerance
Slow to Establish (Initially): It may take a year or two for Pachysandra to fully establish and spread.

Potential for Invasiveness: While generally well-behaved, Pachysandra terminalis can spread aggressively in ideal conditions. Be mindful of this when choosing a planting location. Consider using edging to help prevent spread to other parts of the landscape.

Question 4

Pachysandra Morphology

Accepted Answer

Pachysandra has a distinct morphology that makes it well-suited as a groundcover. Here is a closer look at its key features:

Growth Habit

Spreading Rhizomes: Pachysandra spreads primarily through underground stems called rhizomes. These rhizomes grow horizontally, sending up new shoots at intervals, which leads to the formation of dense mats.
Low-growing: It typically reaches a height of 6-12 inches, making it an ideal groundcover for suppressing weeds and preventing soil erosion.
Evergreen: Pachysandra retains its leaves throughout the year, providing year-round green cover.

Leaves

Arrangement: The leaves are arranged alternately along the stem. They tend to be clustered towards the tips of the stems, forming whorls.
Shape: Oval to obovate (egg-shaped with the narrower end at the base) with coarsely toothed margins.
Texture: Leathery and glossy, contributing to its visual appeal.
Color: Typically dark green, although some cultivars have variegated patterns with white or silver margins.

Stems

Woody: The stems are somewhat woody, especially at the base, providing support for the foliage.
Upright: Stems grow upright, but they often become decumbent (lying on the ground with the tips ascending) as they spread.

Flowers

Inflorescence: Flowers are borne in short, terminal spikes (racemes).
Color: Small and inconspicuous, typically greenish-white.
Blooming Time: Flowers appear in early spring (March-April), but they are not the main ornamental feature of Pachysandra.

Fruits

Type: Small, fleshy capsules.
Appearance: White or light-colored when mature.
Not Showy: The fruits are not particularly ornamental.

Adaptations

Shade Tolerance: The morphology of Pachysandra, particularly its leaf structure and growth habit, reflects its adaptation to shade. The broad leaves efficiently capture diffused light, and the spreading rhizomes allow it to colonize areas with limited sunlight.
Weed Suppression: The dense growth habit and spreading rhizomes help Pachysandra outcompete weeds for resources.

Question 13

Do Pachysandra Plants Attract Pollinators?

Accepted Answer

Pachysandra's attractiveness to pollinators is a bit of a nuanced topic. While they are not considered major pollinator magnets, the answer depends on some key factors:

Species and Variety:

Japanese Pachysandra (Pachysandra terminalis): This common variety has small, inconspicuous white flowers that bloom in early spring. While not particularly showy or attractive to most pollinators, it can offer early-season pollen and nectar to some native bees and flies searching for food sources.
Allegheny Pachysandra (Pachysandra procumbens): This native North American species blooms earlier, even before Japanese pachysandra, offering a valuable early food source for pollinators emerging from hibernation. While its flowers are still small, they can be more attractive to native bees compared to the Japanese variety.

Flowering characteristics:

Inconspicuousness: The small, white flowers of pachysandra lack vibrant colors or strong scents, making them less noticeable to some pollinators like butterflies and hummingbirds.
Short bloom time: The blooming period of pachysandra is relatively short, lasting only a few weeks in early spring. This limits its overall impact on attracting diverse pollinators.

Overall impact:

While pachysandra may not be a powerhouse for attracting pollinators, its early blooms can be particularly valuable in supporting native bees and flies emerging from dormancy before other flowers are available.
Compared to other flowering groundcovers or native plants, pachysandra's contribution to pollinator populations is generally considered minor.

Here are some additional factors to consider:

Double-flowered cultivars: These have even smaller and less nectar-producing flowers, further limiting their appeal to pollinators.
Planting location: If pachysandra is planted in a shady spot with little other flowering competition, it may be more likely to be visited by pollinators in early spring.
Complementary plantings: Combining pachysandra with other early-blooming, pollinator-friendly plants like crocuses, hellebores, or native shrubs can offer a more diverse and attractive food source for a wider range of pollinators.

In conclusion, while pachysandra is not a champion for attracting pollinators, its early blooms can offer some support for native bees and flies. Considering its overall low-maintenance nature and other benefits, it can still be a valuable addition to your garden even if pollinator attraction is not your primary goal.

If you are interested in creating a garden that specifically attracts pollinators, I recommend researching plants native to your region that offer longer bloom times, diverse flower shapes, and stronger scents.

Question 16

Is Pachysandra Invasive?

Accepted Answer

The short answer is that yes, pachysandra can be invasive in some areas. The most common type, Japanese pachysandra (Pachysandra terminalis), is notorious for its aggressive spreading nature.

Here is a breakdown of why it can be considered invasive:

Spreading Habits:

Rhizomes: Pachysandra spreads primarily through underground rhizomes that can travel long distances and readily sprout new plants.
Dense mats: These rhizomes create dense mats that can crowd out native vegetation, preventing them from accessing sunlight, water, and nutrients.

Impact on Environment:

Loss of biodiversity: By displacing native plants, pachysandra can reduce the diversity of plant life in an ecosystem.
Invasive in some areas: The invasiveness of pachysandra varies depending on the region. It is considered a serious threat in parts of the Northeastern United States, Midwest, and Pacific Northwest.
Less problematic in other areas: In its native habitat in eastern Asia and in warmer climates, pachysandra tends to be less aggressive and does not pose a significant threat to native ecosystems.

Alternatives:

Native groundcovers: Consider using native groundcovers that offer similar shade tolerance and low-maintenance benefits without the risk of invasiveness. Examples include wild ginger, coral bells, and Virginia creeper.
Non-invasive cultivars: Some cultivars of pachysandra, like 'Green Sheen' and 'Silver Edge,' are considered less invasive. However, it is still crucial to monitor their spread and ensure they do not escape into natural areas.

Before planting pachysandra:

Research its invasiveness in your region. Consulting local resources like native plant societies or conservation organizations can provide valuable information.

Question 17

When Is The Best Time To Divide Pachysandra Plants?

Accepted Answer

The best time to divide pachysandra plants depends on your climate and personal preference, but there are two main options:

Early spring (after the last frost):

Pros:

The soil is usually moist and workable from winter rains, making digging easier.
Cooler temperatures are ideal for plant establishment and minimize stress.
Dividing early allows new plants time to adjust before the heat of summer.

Cons:

New growth might be damaged during division if it has already emerged.
Flowering might be delayed or reduced in the year of division.

Early fall (before the first frost):

Pros:

Cooler temperatures are still present to minimize stress on the plants.
The soil is typically still moist due to autumn rains.
Plants have had a full season of growth and are well-prepared for the division process.

Cons:

New plants might not get established before winter, increasing the risk of cold damage.
Spring flowering might be slightly delayed in the following year.

Ultimately, the best time for you will depend on your specific climate and priorities. If you live in a warmer climate with mild winters, either spring or fall can work. However, if you have harsh winters, dividing in early spring is generally considered safest for ensuring the new plants have enough time to establish before the cold arrives.

Here are some additional things to keep in mind:

Avoid dividing pachysandra during hot and dry summer months, as this can stress the plants significantly.
Water your pachysandra thoroughly before and after division to help them adapt to the new environment.
Use clean, sharp tools when dividing the plants to minimize the risk of infection.
Replant the divided sections immediately.
Keep the soil moist for the first few weeks after division until the new plants are established.

I hope this information helps you choose the best time to divide your pachysandra plants for a successful outcome!

Question 19

Pachysandra Morphology

Accepted Answer

Pachysandra has some distinct morphological features that make it recognizable and well-suited as a ground cover. Here is a breakdown:

Overall Growth Habit:

Low-growing and spreading: Pachysandra is a low-growing plant that typically reaches heights of 6-12 inches (15-30 cm). This makes it ideal for carpeting the ground and filling in spaces under trees and shrubs. It spreads via underground stems called rhizomes, which produce roots and new shoots. This allows it to form dense mats that can effectively suppress weeds and prevent soil erosion. The spreading habit of Pachysandra also makes it a good choice for covering large areas quickly.

Leaves:

Arrangement: The leaves are arranged alternately on the stems, often clustered towards the tips.
Shape: Oval or obovate (teardrop-shaped) with a pointed tip.
Margin: Toothed or serrated edges.
Texture: Leathery and glossy, giving it a somewhat polished look.
Color: Typically dark green, but some cultivars may have variegation (e.g., white, or silver markings).

Flowers:

Inflorescence: Flowers are borne in short, terminal spikes (meaning at the end of the stems). The spikes are typically 1-2 inches long and contain numerous small, individual flowers.
Color: Usually white but can sometimes have a greenish tinge. The flowers are not particularly showy, but they do add some visual interest to the plant, especially when viewed up close.
Size: Relatively small and not particularly showy. Each individual flower is only about 1/4 inch in diameter.
Blooming Time: Early spring (March-April). The flowers appear before the new leaves emerge, making them even more noticeable.
Pollination: Pachysandra flowers are pollinated by insects, such as bees and flies. The flowers produce nectar to attract these pollinators.
Fruit: After pollination, the flowers develop into small, green capsules that contain seeds. The capsules mature in late summer or early fall and split open to release the seeds. The seeds are dispersed by ants, which are attracted to a fleshy appendage on the seed called an elaiosome.
Significance: While the flowers of Pachysandra are not particularly showy, they do play an important role in the plant's reproduction. They also provide a valuable source of nectar for early spring pollinators.

Roots:

Rhizomatous: Pachysandra is a rhizomatous plant, meaning it spreads through underground stems called rhizomes. These rhizomes produce roots and new shoots at regular intervals, allowing the plant to colonize new areas and form dense mats. This spreading habit makes Pachysandra an excellent ground cover, as it can quickly fill in gaps and suppress weeds. Additionally, the rhizomes help to anchor the plant in the soil and prevent erosion. The rhizomes of Pachysandra are also an important storage organ for the plant, allowing it to survive harsh winters and droughts. In the spring, the rhizomes produce new shoots that emerge from the ground and grow into new plants. This process of vegetative reproduction allows Pachysandra to spread rapidly and form large colonies.

Other:

Evergreen: Pachysandra retains its leaves throughout the year, providing year-round interest in the garden.

This combination of features—low growth, spreading habit, attractive foliage, and evergreen nature—makes Pachysandra a popular choice for landscaping in shady areas.

Question 20

Pachysandra Cultivation

Accepted Answer

Pachysandra is a fairly low-maintenance ground cover, but providing the right conditions will help it thrive. Here is a guide to Pachysandra cultivation:

1. Planting

Timing: Early spring or early fall are the best times to plant Pachysandra. This allows the roots to establish before the stress of summer heat or winter cold.

Location: Pachysandra prefers shade to partial shade. It can tolerate some sun in cooler climates, but direct sunlight, especially in hot afternoons, can scorch its leaves. It often does well under trees where grass struggles to grow.

Soil: Well-drained soil is crucial. Pachysandra prefers slightly acidic soil (pH 5.5 to 6.5), but it tolerates a range of soil types as long as drainage is good. Amend clay soil with compost to improve drainage.

Spacing: Space plants 6 to 12 inches apart. Closer spacing will result in quicker coverage, while wider spacing allows for more gradual spreading.

Preparation: Before planting, prepare the planting area by removing any weeds or debris. Loosen the soil to a depth of 6-8 inches and incorporate compost or other organic matter to improve soil fertility and drainage.

Planting: Dig a hole for each plant that is twice as wide and as deep as the root ball. Gently remove the Pachysandra from its container and place it in the hole, making sure the top of the root ball is level with the surrounding soil. Backfill the hole with soil, firming it gently¹to remove any air pockets. Water the newly planted Pachysandra thoroughly to settle the soil and help the roots establish.

2. Watering

Establishment: Water regularly after planting to help the roots establish.
Mature Plants: Once established, Pachysandra is relatively drought-tolerant. However, it benefits from watering during prolonged dry periods.
Avoid Overwatering: Overwatering can lead to root rot, so make sure the soil is moist but not soggy.

3. Mulching

Benefits: A 2-3 inch layer of organic mulch (shredded bark, pine needles, or compost) helps to:

Retain soil moisture
Suppress weeds
Moderate soil temperature

Application: Keep mulch a few inches away from the plant crowns to prevent rot.

4. Fertilizing

Light Feeder: Pachysandra is not a heavy feeder.
Optional Fertilizing: An annual application of a balanced, slow-release fertilizer in spring can promote healthy growth.

5. Maintenance

Pruning: Pachysandra rarely needs pruning, but you can trim it back in early spring to control its spread or remove any dead or damaged foliage.
Dividing: Overgrown patches can be divided in spring or fall to create new plantings.

6. Pests and Diseases

Generally Resistant: Pachysandra is generally pest and disease resistant.
Potential Issues:

Volutella blight: A fungal disease that can cause leaf spots and stem dieback. Ensure good air circulation and avoid overhead watering to prevent this.
Scale insects: These can infest Pachysandra, causing yellowing and stunted growth. Treat with insecticidal soap or horticultural oil if necessary.

By following these guidelines, you can cultivate healthy and attractive Pachysandra ground cover in your garden.
