DETAILS

Care Instructions
Western Coneflower thrives in full sun and requires moderate temperatures. It prefers soil that dries out partially between waterings and can tolerate a range of humidity levels. Regular watering is essential during the growing season, but the soil should not be waterlogged. This plant can handle cooler temperatures and will enter a dormancy period during the winter months.
Soil
Rudbeckia occidentalis prefers well-draining loam soil. It can tolerate a range of soil types but thrives best in nutrient-rich soil with good drainage. Adding organic matter can improve soil quality and support healthy growth.
Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable for Western Coneflower. Fertilize the plant in early spring and again in mid-summer to support its growth and flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
Repotting
Repotting is generally not necessary for Rudbeckia occidentalis, as it is typically grown outdoors. However, if grown in containers, repotting should be done in early spring before new growth begins. Choose a slightly larger pot with good drainage and fresh potting mix.
Propagation
Western Coneflower can be propagated by seed or division. Seeds can be sown in the fall or early spring. For division, dig up the plant in early spring or fall and separate the clumps, ensuring each division has roots attached. Replant the divisions immediately.
Pruning
Pruning is beneficial for Rudbeckia occidentalis to maintain its shape and encourage new growth. Deadhead spent flowers to promote continuous blooming. Cut back the stems to the ground in late fall after the plant has finished blooming and entered dormancy.
Toxicity
Rudbeckia occidentalis is not known to be toxic to pets or humans. It is generally considered safe to grow in gardens where pets and children are present.
Additional
Western Coneflower is a low-maintenance plant that attracts pollinators such as bees and butterflies. It is also deer-resistant, making it a good choice for gardens in areas with high deer populations. Mulching around the base of the plant can help retain soil moisture and suppress weeds.
