This sturdy, highly absorbent peat moss forms the 3-inch bed from which we built our hanging herb gardens. Curly and flat Italian parsley may be included around the sides, but I decided to save it for the top layer, with other herbs which grow more upright. Next up was a level of fertilizer-enriched professional potting soil. The top layer accommodated about 15 herbs, such as purple basil, regular sweet basil and chives, with trailing nasturtiums and rosemary planted around the perimeter. I suggest fertilizing a basket such as this one every time you water it.
Water takes out the nutrients and the plants begin to pale in color.
Mahovlic prefers a fish-emulsion fertilizer because it is organic and can be ingested without fear of hurting anything. I don't like to use chemicals on anything I eat. I fertilize everything I water, but with herbs, I use about one-fourth the strength. After basil begins growing substantially, make a traditional pesto sauce, with or without garlic. If an all-basil pesto is heavy for your taste, substitute some parsley for a portion of it and use walnuts instead of more expensive pine nuts.
