The Best Fertilizers
Thanks for the comment, but was simply answering the original post about the best ferts for Java fern and mosses.
Actually, I'd would disagree with tap water not being a good source of nitrates, phosphates and sulfates, though. Nitrates aren't supposed to exceed 10 ppm in municipal water supplies, so there is a reasonable amount in our water. As for phosphates, our ground water is filtered through numerous rock formations where it dissolves phosphates and sulfate is in our rain water. If we have decent lighting, keep to the less demanding plants and add a little of the micro nutrients, our plants will grow well.
