Prepare a sunny spot with well-draining soil adjusted to a pH between 6.0 and 6.5. Since these are tender perennials grown as annuals, start seeds indoors 8 weeks before your last frost date or sow directly after all danger of frost has passed. Press seeds gently into the surface without covering them deeply, as they require light for germination. Expect sprouts to emerge within 7 to 14 days. Space plants 8 to 12 inches apart to ensure good air circulation and healthy growth. Water regularly but avoid wetting the leaves to prevent fungal issues; let the topsoil dry slightly between waterings. Apply a balanced liquid fertilizer every two weeks during the blooming period. Mulch around the base in containers to retain moisture, though this is less critical than proper watering schedules. Watch for aphids and spider mites which can damage foliage; treat with insecticidal soap or strong water sprays if infestations occur. Prevent powdery mildew by ensuring good airflow and avoiding overhead watering. These plants are grown for ornamental flowers rather than harvest, so enjoy the continuous bloom from spring until the first hard frost ends the season.When to Plant Geranium
