There you'll need to keep the plants shaded from direct midday sun. Their greatest enemies are fungus and rot, a problem in steamy climates but not dry ones. To improve your chances of success, give scented geraniums well-drained soil. Potted specimens will appreciate a soilless mix, and in-ground plantings do best with some sand mixed into the soil. Set plants in a raised bed or mound to keep water from pooling around the roots.
Scented geraniums are great container plants and are striking grown as topiaries.
One compelling reason to grow scenteds in beds, however, is that some grow to be large and shrubby and could easily overwhelm a container. Whether they're grown in beds or pots, cut them back when they get leggy. Cuttings can be rooted to start new plants. Cut a stem 2 to 4 inches long just below a node, and place it in a pot filled with a soilless mix. Although the flowers of scented geraniums are not the plant's raison d'etre , they often provide a nice, quiet show.
