It thrives in moist, well-drained soils that are slightly acidic, between pH 5.5 and 6.5. The soil texture can range from loamy to sandy, provided that it is well-draining. It can tolerate alkaline soils up to pH 7.5, but it might not thrive in such conditions.
Cultivation Methods
The Eupatorium urticifolium Reichard var. tomentellum B.L. Robins., also known as the White Snakeroot, is a resilient plant that is easy to grow. It thrives in full to partial shade and can handle a range of soil types, including clay and loam. This plant is known to have a shallow root system, therefore it's important not to plant it too deeply. When planting, it's essential to give each plant enough space to spread, as they can grow up to 3 feet tall and 2 feet wide.
Watering Needs
The White Snakeroot is a drought-tolerant plant, but they still need to be regularly watered, especially during periods of extended dry spells. The best way to water this plant is to provide it with a slow and deep soak every week. Adding a layer of mulch will help retain moisture in the soil, preventing it from drying out too quickly. However, it's essential not to water the plant too much as it can lead to root rot.
Fertilization
The White Snakeroot doesn't require a lot of fertilizer as it can grow well in nutrient-poor soils. However, adding compost to the soil before planting will help provide the plant with essential nutrients and improve the soil's quality. A light application of balanced fertilizer, such as 10-10-10, during the growing season, can also help promote growth. However, it's essential not to over-fertilize the plant, as it can lead to excessive growth and reduced flowering.
Pruning
The White Snakeroot doesn't require regular pruning, but trimming it back will help encourage bushier growth. Prune the plant in early spring before new growth begins. Removing the dead or diseased leaves can also help improve the plant's appearance and overall health. Be sure to use clean and sharp pruners to avoid injuring the plant.
