St John's Wort: Sowing, planting and harvest calendar
How to sow St John's Wort successfully outdoors?
Before sowing St John's wort, check the species and the seed packet: germination requirements and sowing time can vary. To retain the characteristics of a named garden variety, choose an identified plant or a propagation method suited to that variety.
Prepare a small, weed-free patch with fine, well-drained soil, or use small pots to monitor germination more easily. Sow thinly and follow the packet's recommended depth; do not leave 30 cm between every tiny seed. Water with a fine spray and keep the growing medium moist without waterlogging it.
Protect the sowing from drying out, heavy rain and frost if necessary. Once seedlings are well developed, thin them or transplant them gently. Choose their final position and spacing according to the species' mature size. Do not expect germination or flowering within a fixed time.
