If you haven't considered herbs as candidates for hanging baskets, there are several reasons why it may be time to give it a try. Growing herbs in baskets is an ideal solution if you have a problem with slugs. Herbs planted in baskets are also out of reach from pets and curious children. Don't forget the visual element, as herbs are attractive, colorful plants.
Soak sphagnum moss in warm water overnight. Squeeze the excess water from the moss and pack the damp moss at least 1 inch deep in a 12-to-16 inch wire basket.
Fill the wire basket with commercial potting soil. If you are planting Mediterranean herbs such as lavender, sage, thyme or rosemary, fill the container with two parts commercial potting soil and one part coarse sand.
Dig a hole in the potting soil for each herb. Start with the tallest herb, and plant the herb in the middle of the container. The hole should be just large enough for the herb plant's root ball. Plant the smaller herbs around the outer edge of the basket. Lightly tamp the potting soil around the roots. Do not plant the herbs any deeper than they were planted in their nursery containers, or the roots may rot.
Water the hanging basket immediately after planting. Check the potting soil daily, and water only when the soil feels slightly dry to the touch. Don't allow the soil to become bone dry.
Hang the basket where the herbs will be exposed to a minimum of four to six hours of bright sunlight every day.
Apply an organic fertilizer, such as fish emulsion, every other week. Apply a weak solution of fertilizer, mixed according to the package directions.
Snip fresh herbs as often as you like, as snipping will keep the herbs bushy and prevent them from growing long and leggy.
