I am interested in planting St. Johns Wort. Three questions
1. What is the rate per acre of pounds or kilos per acre?
The planting rate for St Johnswort is 0.2-0.8 kg per hectare (ca. 0.2-0.8 lbs per acre).
2. What is the recommended spacing of the plants?
We recommend that you space the plants in rows 20 to 90 cm apart and 20-30 cm apart within the rows.
3. What are the fertilizer and water requirments, and preferred soil pH, and weather conditions?
The plants like well-drained, somewhat dry soil. They are not fussy about pH, nor do they need a rich soil or fertilizer -- except in very poor soil. Light fertilization after harvesting is a good idea.
