Planting & Care

Sow Harz Geranium seeds indoors 6-8 weeks before the last frost. Press seeds lightly into the surface of a moist, well-draining seed-starting mix; do not cover deeply, as light aids germination. Maintain a temperature of 65-70°F (18-21°C) and keep the medium consistently moist but not soggy. Germination can be slow and uneven, so be patient. Once seedlings have developed several true leaves and all danger of frost has passed, harden them off gradually and transplant to the garden.

Choose a location with well-drained soil and partial to full sun. Water regularly during establishment, then reduce frequency as plants mature. Mulch around the base to conserve moisture and suppress weeds. Deadhead spent blooms to encourage continued flowering and maintain a tidy appearance. In late fall, cut back foliage after it dies down to prepare for winter.
