St John’s Wort will be planted 1 per square foot. We like to put them into Smart Pot containers because they can be invasive and grow quite large if not pruned or regularly. St John’s Wort will require full sun to partial shade and consistent watering. Take care to notice what plants are around the area as well, see the companion plant section below. 

Companion Plants:

Companion planting is a vital part of organic gardening. Companion plants assist in the growth of others by attracting beneficial insects, repelling pests, or providing nutrients, shade, or support. There are also plants that do not like being next to each other. Some plants get too tall and can provide too much shade for your plant. Sometimes certain plants attract the same pests, so it is important to try and separate these. St John’s Wort makes a fantastic companion plant to virtually all plants!
