For more than 300 years, these natives of the southern hemisphere have been grown by northern gardeners.

general maintenance:

Deadhead spent flowers regularly, and pinch growing tips in spring to encourage bushy habit. Remove discolored leaves to maintain a tidy appearance. Before the first hard frost, transplant to a pot and overwinter indoors in a bright window, taking care not to overwater, or take cuttings and root them indoors.

pests/diseases:

Caterpillars, gray mold and mildew may occur. Indoors, whiteflies, thrips, spider mites, and mealybugs may also occur.

controls:

Handpick caterpillars. To control gray mold and mildew, reduce soil moisture by allowing top of soil to dry before watering. To control whiteflies, thrips, and spider mites, apply insecticidal soap, following label directions.

how to sow/plant:

Plant in spring. Start with new plants or rooted cuttings. Choose a sunny to partly shady site with moist, well-drained soil, and amend with compost or well-rotted manure. Set plants at the same depth they were in pots, spacing at a distance equal to their mature spread. Water after planting, and mulch to conserve moisture.

water and fertilize:

Maintain uniform moisture all season. For container-grown plants, let the soil dry on top between waterings. Feed biweekly with a balanced, soluble fertilizer; or use a slow-release fertilizer, following label directions.

garden hint:

The unusual leaf shape of stellar geraniums provides a fine texture for many of Martha's container plantings.
