This \u00a0biennial or short-lived perennial is winter hardy to USDA Zones 3-7. It blooms the first year from seed\u00a0set out in early spring. It grows in average, moist, well-drained soils and in full sun.\u00a0 Brown-eyed Susan\u00a0is at its finest in moist,\u00a0compost-rich soils. For maximum bloom time, start seed indoors in late February or the beginning of March. Garden centers sell them in cell\/six packs. Set out seedlings or purchased plants after the last frost date has passed. At planting time feed\u00a0the flower\u00a0bed with a granulated fertilizer such as 10-10-10 or or equivalent plus a secondary feeding in early summer. Deadhead spend flowers to encourage lateral branching and additional\u00a0bloom.\u00a0Removing old spent flowers also prevents\u00a0self-seeding.<\/p>\n

Most disease and pest problems may be avoided if properly sited and care for. In some years\u00a0aphids, rust, powdery mildew, and septoria leaf spots may trouble these annuals. Watch for slugs and snails on young plants.<\/p>\n
