Following these St. John’s Wort care recommendations for watering and feeding can help ensure that your plant grows healthy and vibrant.

Pruning and Maintaining Your St. John’s Wort Plant

Proper pruning and maintenance practices are essential to keep your St. John’s Wort plant healthy and flourishing.

Pruning: Regular pruning helps to promote bushier growth and keep the plant in shape. It’s best to prune the plant in early spring before new growth appears. Begin by removing dead or damaged branches, then trim the remaining branches to the desired shape and size.

It’s critical to use clean, sharp pruning shears to avoid injuring the plant. Additionally, avoid pruning more than one-third of the plant’s growth each year.

Maintenance: Weeding is a critical part of St. John’s Wort maintenance since the plant is susceptible to weed invasion. Keep the area around the plant clear of debris, and mulch to prevent weed growth.

Regular monitoring for pests is also necessary since St. John’s Wort can attract aphids, spider mites, and other common garden pests. Utilize organic pest control methods, such as ladybugs or insecticidal soap, to combat any pest infestations.
