WHEN TO SET OUTSIDE
About a week after last frost, when nighttime temperatures remain above 50°F.
PLACEMENT & CULTIVATION
Geraniums traveled from South Africa and were cultivated and marveled over in glasshouses by the early 1600s, and we love them still for their varied beautiful leaves and flower colors. Provide well-drained soils and allow the soil to dry before watering throughly. Deadhead spent flowers regularly and provide some afternoon shade in hot summer areas.
Watering Details:
Water when the soil becomes noticeably dry down 2" into the pot. Geraniums suffer if the soil stays saturated with water, but will flower more profusely if kept lightly moist.
Fertilizer:
Fertilize twice a month with a balanced formulation such as 15-15-15.
Diseases & Pests:
Aphids and mealybugs can be troublesome; if detected, treat with an insecticidal soap or neem oil. Avoid botrytis or gray mold by spacing properly, not wetting the foliage when watering, and keeping dead plant material, such as spent flowers and leaves, cleaned up.
