Hi, I'm Stan Defreitas, "Mr. Green Thumb". St. John's Wart. Not one that you've probably grown but maybe you should. It has a beautiful yellow flower and one that can be used as a, well it's an herb in many different capacities. It's been rumored and alleged that this plant can help with some woes as well. So you might check with your local herbalist for some uses for St. John's Wart but we're going to tell you, as far as growing it, make sure it's in a well-drained soil. Usually, you're going to add a good amount of PEET and perlite. Usually about 50/50 on your combination. As far as fertilization, about every two to three weeks if you are using a water soluble at about half strength. Or, if you are using a time-released fertilizer make sure that you incorporate in the beginning. And, if you are growing it over a long season maybe add a little bit more of the time-released after about about three to four months. St. John's Wart will do well we said in full-sun to partial shade. Make sure that it has the well-drained soil but that it also gets a good deal of moisture. When you do pot it out of this container, step it into one size container just a little bit large and you can keep it in there for the rest of it's duration.
