watering
Black-eyed Susans should be watered once or twice a week, depending on the conditions in your area. In hot, dry areas, plants may need more frequent watering as much as daily or every other day to keep the soil moist. In cooler, lightly moist zones, this plant may need less water, with once a week being sufficient. Whenever watering, ensure the soil is saturated with enough water to reach the plant’s roots, and allow the water to drain fully. Do not let the soil become soaked or allow the plant to sit in standing water. Avoid overhead watering if possible to prevent fungal diseases.
sunlight
Black-eyed Susan is an easy to grow perennial that does best in full sun. It grows best in well-drained soil with a pH of 6.0 - 7.5. It prefers about 6 to 8 hours of sunlight each day, staggered throughout the day to prevent damage from excessive heat. In the summer, it prefers cooler temperatures with partial shade during the hottest hours of the day. In the winter, the plant may need a few hours of direct sunlight a day to survive if the temperature dips below freezing.
pruning
Black-eyed Susan (Rudbeckia 'American Gold Rush') should be pruned in late winter or early spring, just before new growth begins. Pruning will encourage healthy new growth, promote more blooms, and keep the plant from getting too spindly. To prune, remove dead or damaged stems and any excess twigs or branches. Trim any shoots of growth that appear too long or extend too far away from the main stem. If needed, lightly prune the shrub to the desired size and shape. Finally, tidy up the plant by removing any errant leaves.
