Japanese Spurge Plant Care
Being tolerant of both shade and drought, the pachysandra plant is easy to care for. You can grow it in clay soil or dry soil in USDA zones 4-8 easily. It will form a dense shrubby mat, even with less watering and limited to no access to direct sunlight.
As mentioned, Pachysandra terminalis has excellent tolerance to shade. Not all ground covers can grow in shade and often die due to limited light access. In fact, if the foliage gets too much direct sunlight, it can actually turn yellow.
Japanese pachysandra ground cover has low to medium watering needs. You’ll need to water the plant to keep the soil moist, but make sure there is good drainage. Standing water will expose the roots and stem to fungal attacks and rotting. Also, it’s best to avoid overhead watering as it can put your plant at undue risk for disease.
Like many plants, it’s going to want a rich, well-draining soil. If you need to amend your native soil because it’s devoid of nutrients or simply too heavy clay, you can add a bit of compost to improve it.
Overall, you don’t need to stress much about the soil – it can handle a wide range of soil pH, as well as soil texture.
Pachysandra ground cover grows well with regular applications of organic fertilizer. You can use a 10-10-10 fertilizer in the spring when new growth begins, and taper off as fall approaches. Make sure you fertilize at the soil surface, or give it a rinse if you apply overhead. If amending a larger area before transplanting, use 1 to 2 pounds of a balanced organic fertilizer per 100 square feet.
Propagation of spurge ground cover is easy. You can do so by root cuttings and transplanting clumps. You can also grow newer sets of pachysandra plant by removing the seedlings from the older plant and planting them in the potting soil.
Japanese pachysandra is a slow-growing perennial and is not invasive in nature. Therefore, you don’t need to prune it back unless you feel it’s getting a bit too overgrown for its space. You can trim it to shape for aesthetic reasons, however.
Pest-wise, you’ll rarely face any serious problems with your spurge plant. It’s a fantastic ground cover for deer, as they tend not to like munching on it.
It’s tolerant of drought and also helps with erosion control, making it a great slope or bank planting option.
However, here are a few things to watch out for.
Diseases and Growing Problems
You’ll only face growing problems and diseases in your pachysandra ground cover if you don’t maintain consistent watering frequency, or choose a soil that has poor drainage. Over watering and planting in soil that holds too much water will result stem and root rotting.
Planting your spurge ground cover in direct sunlight will cause yellowing of leaves. Leaf blight can be a serious problem and would require an organic fungicide application to get rid of effectively.
Keep an eye out for different types of scale insects and mites in your Japanese pachysandra. If you see any of these pests on your plant, make sure to use an organic insecticide to get rid of them right away.
