western ironweed

Western ironweed (Vernonia baldwinii) should be watered once a week in summer and fall. During the active growing season, deep watering is beneficial as the plant's roots can extend deeply. Water slowly and evenly, allowing moisture to penetrate the soil. Water your western ironweed enough to moisten the soil to a depth of at least 8″. Watering should be stopped during winter, unless the plant is growing in a container. If it is, it should be watered only when the top inch of the soil feels dry.

Western ironweed enjoys full sunlight for most of the day. For optimal growth and flowering it wants at least 6-8 hours of direct sun from early morning to late afternoon. If planted in a shady or partially shaded area the growth and flowering will be stunted. It is also important to note that if this plant receives too much sun, during especially hot days, it will not be able to thrive as it is not tolerant of high temperatures.

Western ironweed (Vernonia baldwinii) is a plant species native to North America. For optimal growth, Western ironweed should be pruned in early spring before buds are visible. Pruning should consist of removing any dead or diseased stems, as well as cutting any long or unruly stems back by 1-third of their height. This will help promote bushiness and produce fresh new growth. Western ironweed is a short-lived perennial and can become overgrown in 3 to 4 years. In such cases, cut back the entire plant by 1-third of its height to encourage new growth and revitalize the plant. Additionally, some flowering stalks can be pruned off to help encourage flowering of new shoots.
