Plant Happy Face Hearts® Potentilla in well-drained soil with full sun exposure. Space plants about 2-3 feet apart. Water regularly during the first growing season to establish a deep, extensive root system. Once established, reduce frequency, allowing soil to dry between waterings. Fertilize in early spring with a balanced, slow-release fertilizer. Prune lightly after flowering to maintain shape and encourage new growth. Protect from extreme heat and cold.
