watering
Black-eyed Susan (Rudbeckia hirta 'Irish Spring') should be watered regularly. Keep the soil moist but not soggy. Water deeply every 7-10 days, allowing the top 2 inches of soil to become dry between waterings. Avoid frequent, shallow watering. During periods of hot, dry weather, water more frequently, but do not overwater. It's important to water at the base of the plant to reduce the risk of disease.
sunlight
Black-eyed Susan (Rudbeckia hirta 'Irish Spring') should be planted in an area with full sun exposure for best blooming results. This type of plant requires about 6-8 hours of direct sunlight per day to thrive. If it does not receive the proper amount of light, blooming may be reduced. It is important to not plant the black-eyed Susan in too much shade or too much sun as either can negatively effect it.
pruning
Black-eyed Susan (Rudbeckia hirta 'Irish Spring') should be pruned back in the early spring before the plant begins to grow actively. Pruning is important to help create a more bush-like plant as the stems tend to flop over. Pruning should be done by cutting back the old growth to about 6-8 inches high. Removing any faded flowers or stems with seed heads will also help to create a bushier form. Deadheading throughout the growing season can also help to increase flowering. Caution should be taken not to over prune the plant as this will weaken it.
