Exposure & Establishment: Pachysandra can adapt to light considerations, but it performs best when in shade or only partial sun. The best time to plant this groundcover would be early in the spring. You can plant it at other times, but you’ll have an increased need for watering, and may lose a percentage of your plants. Likewise, if you install it in fall, you may lose some of the young, tender plants to winter injury. Be sure to prepare the soil where you are planting. Till it to loosen the soil so the pachysandra can root deeply and quickly. Add fertilizer and organic compost if possible, and cover the area with mulch to help retain moisture.
Another major consideration for pachysandra is the disease Volutella blight. This also causes wilting or dead areas in the bed. Individual plants will exhibit irregular tan to brown lesions on the leaves and eventually coalesce until the entire leaf dies. Inevitably, the disease will spread to stems and cause even more damage. Insect infestation, winter injury, excessive sun exposure and drought will increase the chance for this disease to grow. Moist, dark conditions will cause Volutella blight to spread, so make sure the stand of pachysandra is able to dry out. If there is excessive leaf litter under the plants, or the stand is even too thick, this will promote the disease to spread. Yes, you may need to thin out your thick pachysandra stand slightly. Fungicides can also be applied along with insecticidal sprays to reduce fungal growth during summer months when this disease begins to develop.
