Care Instructions
Spotted St. John's Wort thrives in bright, direct sunlight and prefers moderate temperatures. It should be watered when the soil partially dries out, and it benefits from moderate humidity levels. Regular pruning helps maintain its shape and encourages new growth.Soil
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is not waterlogged, as it can lead to root rot. A mix of garden soil with compost can provide the necessary nutrients.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10 during the growing season. Fertilize every 4-6 weeks to support healthy growth and flowering.Repotting
Repotting is generally not necessary for outdoor plants, but if grown in containers, repot every 2-3 years or when the plant outgrows its pot. Choose a slightly larger pot and refresh the soil mix.Propagation
Hypericum punctatum can be propagated through seeds or cuttings. Sow seeds in the spring or take cuttings in late spring to early summer. Ensure the cuttings have at least two nodes and plant them in a well-draining soil mix.Pruning
Prune the plant in early spring to remove dead or damaged stems and to shape the plant. Regular pruning encourages bushier growth and more abundant flowering.Toxicity
Hypericum punctatum is generally non-toxic to pets and humans. However, it is always best to prevent pets from chewing on any plant material.Additional
